[web2py] Upload error with 2.23.0? ('Field' object has no attribute '__dir__')

[Stephan]

Hi,
uploads with sqlite doesn't work anymore in my apps. I recognized this 
after installing ver. 2.23.0. Maybe it's just a coincidence. Here is the 
code:

127.0.0.1.2022-12-29.16-19-26.abbdc90d-cd14-467e-bd96-12f360bf1d4d

[web2py] Upload images to folder outside web2py

['Annet' via web2py-users]

To upload images to separate folders outside web2py I set the upload folder 
with the model definition:

UPLOADSDIR = '/home/me/apps/static/'

db.define_table('mytable',
Field('image', 'upload', autodelete=True, uploadfolder=os.path.join(
UPLOADSDIR, 'vertexID%s' % session.vertexID),
...)


I use the standard download function:

def download():
return response.download(request, db)


The form:

form = SQLFORM(table, row, deletable=True, upload=URL('default', 
'download'), showid=False, buttons=buttons)
if hasattr(request.vars.image, 'filename'):
form.vars.imagefilename = request.vars.image.filename


and to process the form:

if form.process().accepted:
if row and form.vars.image__delete:
file = row.image
os.remove(os.path.join(UPLOADSDIR, 'vertex%s' % 
session.back_end_vertexid, file))


In web2py 2.17.2 this all worked without problem, however, after upgrading 
to
web2py 2.20 it no longer works. The image doesn't show in the form, it's 
marked
with a broken link icon, and when I click the file link I get a page not 
found error.
Also when I upload a new image, the old one isn't being deleted, so the 
images pile
up in the folder.

I hope someone knows how to solve this issue.


Kind regards,

Annet

[web2py] upload - can I get the path to original file

['jim kaubisch' via web2py-users]

Hi

In a file upload, I want to store both the original filename AND the path 
to the original file (to cover the case of files with the same name but 
from different folders)
I'm successfully getting the filename from "request.vars.the_file.filename" 
as documented, but is there somewhere I can retrieve the path?

Thanks

[web2py] Upload field causing a temp file issue

[Paul Ellis]

I have 2 similar controller functions using SQLFORM() with an upload field. 
One works and one is giving an error online (not when testing locally). I 
suspect a file system permission problem but I am not sure.
The error only occurs if an image is uploaded. 
The extra processing after the form is submitted is not the cause. I 
removed it as a test and the error remains.

The error:

[web2py] Upload - need help

[wswiecho]

Hello,

I have an upload field in my form. It works fine when I run it on the same 
machine as the web2py service. The issue comes when I run the service on 
the server and the UI on a different machine. The issue is the fact that 
existence of the file path I enter is checked on the server as opposed to 
the machine from where I try to upload the file. How do you fix it? This is 
the definition of the form I have:


list_dictionary_names = os.listdir(os.getcwd() + 
*'/applications/mcarriage_console/uploads/dictionaries'*)
list_dictionary_types = list(set((i[:i.find(*'_'*)] if i[:i.find(*'_'*)]
 == *'ITCR'* else i[:i.find(*'_D'*)].replace(*'_'*, *' '*))  for i in
 list_dictionary_names if i[0].isupper()))
obj_admin = AdminClass(auth, db, session)


alert_message = *'Process of uploading may take a few minutes. The file 
content is first inserted into MARS database. '*
alert_message += *'Then content of the previously active file is 
checked for any updates. '*
alert_message += *'If no changes were made the content of the 
previously file is removed '*
alert_message +=  *'and the previously active data dictionary is set 
inactive.'*
session.message = alert_message
#obj_message = MessageDisplay(session.message)
button_list = [INPUT(_type=*'submit'*, _value=*'Submit'*)]


form = SQLFORM.factory(
   Field(*'file_type'*,
 label = *'Dictionary Type'*,
 requires=IS_IN_SET([ i[*'DICTIONARY_TYPE'*]
 for i in db(db.DATA_DICTIONARIES.ACTIVE_ID == *'A'*).select(
db.DATA_DICTIONARIES.DICTIONARY_TYPE)] if len(db(
db.DATA_DICTIONARIES.ACTIVE_ID == *'A'*).select(
db.DATA_DICTIONARIES.DICTIONARY_TYPE)) > 4 else list_dictionary_types  )),
   Field(*'file_version'*,
 label = *'Dictionary Version'*,
 requires=IS_NOT_EMPTY()),
   Field(*'file_directory'*,
 label = *'File Path'*,
 _type = *'string'*,
 requires=IS_NOT_EMPTY()
 #uploadfield=False,
 #uploadfolder
=os.path.join(request.folder,'uploads/')
 ),
   #Field('file', 'upload', requires = IS_LENGTH(
minsize=0, maxsize=1048576, error_message='File is too huge.')),
  buttons = button_list
  )

Re: [web2py] Upload an image from front-end

[Marco Mansilla]

I'm looking for a similar solution, but the front-end is written in VueJs,
and Axios for POST and GET requests, since I couldn'd find a way to send
the actual file to the server I'm going with a solution close to your
second option, has some extra steps but it's clean and somehow more verbose
for multiple uploads, loading notifications and progress tracker.

[web2py] Upload an image from front-end

[Πέτρος Χατζηλάμπρος]

Dear all,
in my last project I am using the following architecture:

   -  Web2py is used only at the back-end. 
   - The front-end is developed using React by an other developer. 
   - The front end sends GET and POST requests to web2py and web2py 
   responds with json. 
   
Using this architecture what is the best way to send and store an image 
from the browser to the web2py ? I am thinking to use one of the three 
following methods:

   - use a web2py controller to create a form with an upload field, sent 
   the hidden form inputs(_formkey and _formname) to front-end and then the 
   front-end will use javascript to imitate the behavior of the browser
   - The front-end will use javascript to convert the file to base64 format 
   and it will send it with a POST request to web2py. Then web2py will convert 
   the base64 string into a file and it will save it  to folder /uploads using 
   a controller

Which method you think that fits better to web2py ?

[web2py] Upload to auth_user

[Tiago Barrionuevo]

Hi,

I'm trying to upload images to auth_user without success. I already did it 
with other database tables with no problem.

My code:

model:

auth.settings.extra_fields['auth_user'] = [
Field('picture', 'upload', autodelete=True, label=T('Picture')),
]


I'm using the appadmin interface (myapp//appadmin/manage/users).

When I submit the Edit form with a chosen image the form processing stops 
with submit button showing "Working...".

With auth_user I didn't even need to setup SQLFORM() call or download 
function. I don't know if I'm missing something!

Running Web2py version 2.15.3.

[web2py] upload and download, in order to manage attached files

[J-Michel Angers]

Hi,
I'm building an app to fill "PurchaseRequest", to valid it by the staff, 
and then type a "PurchaseOrder". Exactly like with a paper form that we 
fill, and get signatures to valid it.
Now the main boby of the app works (fill the form, set/choose the route, 
send emails to the concerned persons (by request to the Active Directory), 


Now I need for this app, to input one or more (or none) attached file 
(quotation in PDF format, Excel file, technical data in PDF format)...
I can upload this files, sort them, display the titles, ...
Impossible to show the file.
I see the file in the OS directories (/upload/, where  is 
TPJ.Document.<.>.extension).
I have a customised html page, but either I get "unknown page", or I get 
... nothing. When I manually copy the link into explorer, I see the file 


The model (only the table for attached) :
dbW.define_table('TPJ',
Field('NumDA',type='integer'),
Field('Document',type='upload',uploadfield=True,uploadfolder=os.path.
join(request.folder,'uploads')),
Field('Titre'),
rname='WFDA_DA_PJ',
migrate=False)



The controlleur for filling in is only a test fonction :
def saisie_pj():
form1 = SQLFORM(dbW.TPJ)
if form1.process().accepted:
response.flash = 'Votre PJ a été enregistrée'
return dict(form1=form1)



The display (and Iif possible showing the files):
It is nested in the main form (and this form is now quite long)
.
form = SQLFORM(dbW.WFDA_DemAchat, DA, formstyle ='bootstrap3_inline', 
buttons=LBoutons)
PiecesJointes = dbW(dbW.TPJ.NumDA==NumDA).select(dbW.TPJ.Titre, dbW.TPJ.
Document)
.



And now the html view..

{{=form.custom.begin}}


DEMANDE D'ACHAT: {{=form.custom.dspval.id}}

..

{{=form.custom.submit}}
{{=form.custom.end}}



Pièces jointes :

{{for ligne in PiecesJointes:}}
 Avec A : {{=A(ligne.Titre, 
_href=URL('upload',ligne.Document))}}
 Avec file:
{{=ligne.Titre}}
 
 {{pass}}







With the "=A(ligne.Titre...", I see the link 
"http://127.0.0.1/da/upload/TPJ.Document.blabla.pdf. When I click I get 
"404 unknown page"

[web2py] Upload complete, but with error

[Dave S]

When uploading a file from one of our Windows clients, we sometimes find 
this in the web2py.log file:

   File "/home/ec2-user/web2py/web2py-2.14.6/gluon/rocket.py", line 1337, in

  File "/usr/lib64/python2.7/socket.py", line 228, in meth

error: [Errno 32] Broken pipe


Is this basically a timeout because the end of transfer wasn't detected 
properly?  Or is something going wrong with preparing and sending the 
response?

Re: [web2py] Upload Video

Yes u can.

And not, "The normal "upload" type in db only lets me choose an image"
don't do that - RTFM:

http://web2py.com/books/default/chapter/29/06/the-database-abstraction-layer#More-on-uploads

You are probably including some code from examples and using a image
validator for the upload field.. and pls post your code or else no
body will help.

[web2py] Upload packed application ... error message clarity

[Dave S]

I was having trouble using the upload app button.  "errors in form; please 
check it out", and "invalid package name".  It may be that I'm slow today, 
but it took me a while to realize that I was supposed to fill in the 
application name, not just the filename.  

1) maybe changing the color of the text area that's "bad" would help people 
like me
2) is it practical to use the "middle" of the filename to obtain the 
[default] application name?

[web2py] upload field and IS_IMAGE

[Kirill Shatalaev]

Hello.

I have in model:

Field('avatar', 'upload', required=False, autodelete=True, label=T('Avatar'),
  uploadfolder=os.path.join(request.folder, 'static/images/avatars'),
  requires=[IS_LENGTH(16384), IS_IMAGE()])


Well, the logic is simple: "avatar is not necessary, but when it uploaded, it 
must be image size of <= 16KiB".


But I *can not* submit form without image uploading, error is "Invalid Image" 
always.


Is it a bug or I do not understand something?

[web2py] Upload file from 'static/images' to database

[Nick Michael]

Hi, I'm having some trouble and was hoping someone could point me in the 
right direction.

I'm creating an application which has an input form which stores to a 
database. One entry accepts images, but can also be left empty (by using 
requires IS_EMPTY_OR). I also have a placeholder image saved under 
'static/images'. I want to make it so that if the upload file is left 
empty, I store the placeholder image from the 'static/images' folder in the 
database entry, otherwise it'll use the image that was uploaded by the user.

Here's my current implementation:

if request.vars.image == "":
##Enter Code Here##
else:
image_file = db.user_items.image.store(request.vars.image.file, 
request.vars.image.filename)
addItemToData (request.vars.name, request.vars.collection, 
request.vars.tag, request.vars.value, request.vars.story, image_file, 
auth.user.id, request.vars.tradeable)
redirect(URL('default', 'profile'))

[web2py] Upload locations in web2py_ckeditor plugin

[David Orme]

Hi,

I've installed the web2py_ckeditor plugin from:
https://github.com/timrichardson/web2py_ckeditor4/releases

I think this will working really nicely for providing a table of simple 
blog posts, but I'd like to control where uploaded files get stored. I had 
a look at the source and it seemed like ckeditor.settings.uploadfs might be 
the answer, but I can't get it to work. Everything just gets stores in the 
root of app/uploads.

In an ideal world, I'd like to able to modify this in different controllers 
so that uploads for 'blog' posts go to one folder and uploads for 'news' 
posts go to another.

Cheers,
David


*db tables*

from plugin_ckeditor import CKEditor
ckeditor = CKEditor(db)
ckeditor.define_tables()

db.define_table('blog_posts',
Field('authors', 'string'),
Field('title', 'string'),
Field('content', 'text', widget=ckeditor.widget))



*controller*

def new_blog_post():

# set where the controller is going to save uploads
ckeditor.settings.uploadfs = 'uploads/blog'

form = SQLFORM(db.blog_posts)

if form.process().accepted:
response.flash = CENTER(B('Blog post submitted.'), _style='color: 
green')
else:
response.flash = CENTER(B('Problems.'), _style='color: red')

return dict(form=form)

[web2py] upload fields and curl

[Dave S]

Loose end from 
:

I have an upload field, and 1 controller to upload to it via SQLFORM and 1 
controller to access it via REST.  Using the SQLFORM, the local filename is 
included in the file data (as seen in the JSON-like representation printed 
to the console during debugging), which is handy.

I've been using CURL to access the REST controller, and I haven't figured 
out how to send the local filename.  As a workaround, I use a string field 
(populated by the URL) to provide a filename.  I would prefer to have this 
field be redundant as it is in the SQLFORM dialog (or perhaps repurpose it; 
there are other strings I might want to record in the record).  My current 
CURL invocation looks like

curl --request POST -T /path/localfile.txt --user user@server pwd
 
http://SERVER/uploader/default/uplift/uploadf/ 

localfile.xt

How can I emulate the SQLFORM's data?

[web2py] upload file to rest service on GAE

[James Burke]

I'm having some trouble uploading/accessing a file on Google App Engine 
(GAE).

This is the code used to store the file:

@request.restful()
def workspace():
def POST(*args,**vars):

workspace_id = db.workspace.insert(repository=request.vars.
repository,
name=request.vars.name,
file=db.workspace.file.store(
request.vars.file))
from gluon.serializers import json
return json(dict(workspace_id=workspace_id))


return locals

When I check the field in the Datastore viewer (file_blob) it returns "No 
data was found".

When I change the above code to:

@request.restful()
def workspace():
def POST(*args,**vars):

workspace_id = db.workspace.insert(repository=request.vars.
repository,
name=request.vars.name,
file=db.workspace.file.store(
request.vars.file))

print '###'
print db.workspace(workspace_id).file
print db.workspace.file.retrieve(db.workspace(workspace_id).file)
print '###'

from gluon.serializers import json
return json(dict(workspace_id=workspace_id))


return locals

I get the following in the log:

###

[web2py] upload file path

[Manuele Pesenti]

Hi!
What's the right way of rebuilding file path of any record of my table
with an upload field like:

Field("archivio", "upload", uploadfolder=archive_upload_path,
uploadseparate=True)

where archive_upload_path = os.path.join(request.folder,'uploads/archives')

maybe something like:

path_to_file = os.path.join(db.mytable.archivio.uploadfolder, ,
row.archivio)

Thank you very mutch in advance

[web2py] upload and sqlform.grid

[Laurent Lc]

Hi,

I'd like to show pics for each records when i return a grid. My function is 
:

def showonly():
query=(db1.test.present=='present')
grid = SQLFORM.grid(query=query, user_signature=False, maxtextlength = 
40,deletable=False, \
editable=False, create=False, details=False, \
links=[dict(header='picture',body=lambda row: 
A(IMG(_src=URL('download', args=row.picture), _width=50, _height=50), 
_href=URL('download', args=row.picture)))], \

fields=[db1.test.nom,db1.test.burtelephone,db1.test.mail,db1.test.groupe, 
db1.test.picture],orderby=db1.test.nom) 
return dict(grid=grid)  

The pic does not appear (header pb i think, but i follow the doc and i do 
not understand)
And there are 2 times the field "picture" in the columns (it works when i 
click on the link "file")

So i would like to have just one column "picture" whith a pic inside 

thank you

[web2py] Upload via ajax

[Jose]

Hi

I want to upload a file via ajax. What I have working for when the file is 
stored in a folder, the problem and when I want it stored in a blob field.

*In upload_picture function I do not know how to put the value of 
image_blob *

The code is as follows

==
/models/db.py
==

tb_pictures = db.define_table('pictures',
Field('name'),
Field('image', 'upload', uploadfield='image_blob'),
Field('image_blob', 'blob', writable=False, readable=False),
)



==
/controllers/default.py
==
def pictures():
return dict(f=LOAD('default', 'formpictures.load', ajax=True, ajax_trap=
True))

def formpictures():
form = SQLFORM(tb_pictures, _id="formuploadajax")

return dict(form=form)

def upload_picture():
fd=request.vars.image
tb_pictures.insert(
name=request.vars.name,
image=fd,
*image_blob=fd,* #<===
)

#return



==
/views/default/formpictures.load
==


$(function(){
$("#formuploadajax").on("submit", function(e){
e.preventDefault();
var f = $(this);
var formData = new FormData(document.getElementById(
"formuploadajax"));
$.ajax({
url: "{{=URL('upload_picture')}}",
type: "post",
//dataType: "html",
dataType: "script",
data: formData,
cache: false,
contentType: false,
processData: false,
success: function (result) {
alert(result);
}
})
});
});


{{=form}}

[web2py] Upload files via ajax using jquery.form

[pang]

The web2py book says:

Because Ajax post does not support multipart forms, i.e. file uploads, 
 upload
 fields will not work with the LOAD component


This is a pity, as we are expected to split backend and frontend these 
days, and ajax comes handy. I have found other people hitted the same 
problem but didn't find a solution:

   - 
   
https://groups.google.com/forum/#!searchin/web2py/upload$20file$20ajax/web2py/6yL1pNd7QE0/-9z7DWoQyDwJ
   - 
   
https://groups.google.com/forum/#!searchin/web2py/upload$20file$20ajax/web2py/PmvIKczfn84/MCJso4P0vXEJ
   - 
   
https://groups.google.com/forum/#!searchin/web2py/upload$20file$20ajax/web2py/IHSnr6cppBQ/2FCBSgCCUTcJ

Then I realized there is one part of my app that has been doing file 
uploads via ajax for a long time. I grabbed it from this example appliance 
by Massimo, and never researched the code in depth:

https://github.com/mdipierro/web2py-appliances/tree/master/FileManager


I did some research and found it is using the jQuery.form library, which 
can do file uploads via ajax:


http://malsup.com/jquery/form/#file-upload


I write this in the hope that people trying to do fle uploads via ajax find 
this library, and the example app by Massimo, and it helps them.

[web2py] Upload multiple files and do background processing

[Phillip]

 

I need directions for properly executing the following


 Drop a window for selecting multiple files for upload
 Process the files in the controller (ideally using the scheduler to 
prevent the application from hanging)


Since it appears that the processing must occur after all files are 
imported to use the scheduler, is there a standard way of retrieving the 
id's of the uploaded files?


Please let me know if you need more info


Thanks,


PhillipVW

[web2py] Upload field default value ?!!

[António Ramos]

Hello i have an app that was designed with some required upload fields.

Now after 1 year and around 5gb in my download folder, someone tells me
that the upload fields are not required anymore under some scenarios.

I cannot delete the required value from my dal because the sqlite does not
let it.

So to bypass this problems is there anyway that i can default the upload
field to some trashy value ?

any other thoughts ?

Regards
António

[web2py] Upload path broken since 2.9.11 update

[Louis Amon]

Hi,

My website has been using web2py for a few months now, and we handle 
pictures using Amazon S3 and Cloudfront for storage and distribution.

The corresponding code in web2py looks like this :

Field('picture_1',
  type='upload',
  requires=IS_EMPTY_OR(IS_IMAGE(extensions=('jpeg', 'png'))),
  uploadfolder='offer/picture_1',
  uploadfs=settings.amazon_fs,
  autodelete=True,
  represent=lambda value, row: cloud_download(value) if value is not 
None else None,
  )


When a picture was uploaded through a form, it was uploaded to our Amazon 
bucket at a path similar to this : 
{bucket_name}/offer/picture_1/offer.picture_1.{timestamp_hash}.{filename_hash}

I recently updated to 2.9.11-stable+timestamp.2014.09.15.23.35.11 but now 
it seems that the uploadfolder does not get prefixed to the path.
i.e. : my uploaded pictures now go to : 
{bucket_name}/offer.picture_1.{timestamp_hash}.{filename_hash}


Was there something in the 2.9.11 patch that modified the behaviour of 
uploads through a filesystem ?

Is there a quick fix for mend these broken paths ?

Re: [web2py] Upload path broken since 2.9.11 update

[Louis Amon]

Hi Anthony,

I was using 2.9.5 before the upgrade.

In the end, I found that it may be that the part of the code than handles 
uploads through a filesystem never did work with the « uploadfolder » attribute 
(i.e. it might have been a patch I made a few months ago and lost in the 
process of the upgrade).

In any case, here is the solution to my issue if anyone ever meets it :

In dal.py, line 10211:
 os.makedirs(path)
 pathfilename = pjoin(path, newfilename)
 if self.uploadfs:
-dest_file = self.uploadfs.open(newfilename, 'wb')
+dest_file = self.uploadfs.open(pathfilename, 'wb')
 else:
 dest_file = open(pathfilename, 'wb')
 try:


In dal.py, line 10249:
 stream = StringIO.StringIO(data)
 elif self.uploadfs:
 # ## if file is on pyfilesystem
-stream = self.uploadfs.open(name, 'rb')
+fullname = pjoin(file_properties['path'], name)
+stream = self.uploadfs.open(fullname, 'rb')
 else:
 # ## if file is on regular filesystem
 # this is intentially a sting with filename and not a stream


With this, the DAL should be able to both write and retrieve files through a 
filesystem whilst still taking in consideration the prefixed folder (i.e. the « 
uploadfolder » attribute).
That’s very handy if you need to specify multiple upload locations in your 
bucket.

I really don’t have any time to setup my environment for proper testing  git 
contributions.
I still consider myself to be a novice and I’m the only dev in my startup right 
now…

But I do intend to contribute to the framework in a few weeks’ time, when my 
startup will have raised funds :)

[web2py] Upload to static folder in other application

[Annet]

I web2py/applications I have 3 applications 1 application 'dbmodel' that 
contains the .table files in the databases folder
and static files in the static folder, 1 application 'my' that serves as a 
backend and 1 application 'init' that serves as
a frontend.

As a way to reduce memory usage webfaction recommends a symbolic link to a 
static-only application which serves the 
contents from the static folder of my application 'dbmodel'.

I have the following table definition:

db.define_table('img_logo',
Field('nodeID', 'reference nd_node', ),
Field('imageFilename', length=128, writable=False, readable=False),
Field('image', type='upload', requires=[IS_IMAGE(extensions=('gif', 
'jpg', 'jpeg', 'png'), maxsize=(256, 128), error_message='Afmeting: 
maxWidth is 256 pixels maxHeight is 128 pixels. File format: gif, jpg, 
jpeg, png'), IS_LENGTH(32*1024, error_message='File size overschreidt 32 
KB')], label='Logo * ', autodelete=True),
migrate = False)

In the backend application I have a function which lets the user can upload 
a logo file. In the function I have the following
settings:

folder = 'nodeID' + str(nodeID)
 db.img_logo.image.uploadfolder = os.path.join(request.folder, 'uploads/%s' 
%folder)

To do what Webfaction recommends I wonder whether it is possible to upload 
the logo file to:

/applications/dbmodel/static/uploads/foldername

instead of:

/applications/my/uploads/foldername


Kind regards,

Annet

[web2py] Upload field custom manipulation

[Kuba Kozłowicz]

I have three tables:

- invoices
- invoice summaries
- invoice bundles

The website I am working on provides such a functionality, that user 
uploads a file, from which invoices and invoice summaries are generated and 
after being generated they are zipped and put into a bundle.

For each upload I create following structure for storing these files:

invoices/
 /bundle_id/list of invoices of bundle bundle_id/
summaries/
 /bundle_id/list of invoices of bundle bundle_id/
bundles/
 /bundle_id/list of invoices of bundle bundle_id/



So I end up having something that looks like this

invoices/
 /1/list of invoices of bundle_1/
/invoice1.pdf
/invoice2.pdf
 /2/list of invoices of bundle_2/
/invoice1.pdf
/invoice2.pdf
 /3/list of invoices of bundle_3/
/invoice1.pdf
/invoice2.pdf
summaries/
 /1/list of summaries of bundle_1/
/summary1.pdf
 /2/list of summaries of bundle_2/
/summary1.pdf
 /3/list of summaries of bundle_3/
/summary1.pdf
bundles/
 /1/bundle_1/
/bundle.zip
 /2/bundle_2/
/bundle.zip
 /3/bundle_3/
/bundle.zip




where inner folder name is ID of recently created bundle.

Now to provide CRUD functionality I am using SMART GRID and I want to be 
able to display the file of invoice, summary, bundle entries ( by 
displaying I mean I want to display file's name and allow downloading it ), 
when a user either chooses VIEW in the SMART GRID or when he looks at the 
list of entries. Since I've chosen my own folder structure for storing 
these invoices, summaries and bundles I can't do it in a simple way, 
because Web2py uses its own mechanism to store and retrieve files and 
changse file's name. So in each of these tables I store the following 
fields:
Field('f_invoice_file_path', type='string')
Field('f_invoice_file', 'upload')



what I wanted to do is something like this:

def on_before_insert_invoice(fields, id):
db(db.t_invoice.id == id).update(
f_invoice_file=fields['f_invoice_file_path']
)
db.t_invoice._before_insert.append(
on_before_insert_invoice
)

, here actually *fields* contains a list of tuples in following format 
(field, value) so I had to iterate over it to find fields[
'f_invoice_file_path'], I just omitted this part for brevity.

, but I get following error and most likely it is not the proper way to do 
that:

*** RuntimeError: Unable to handle upload

Note that the field:

Field('f_invoice_file_path', type='string')

is saved correctly, I just need somehow to make upload field point to that 
location. The next weird thing is that variable *fields* doesn't contain 
field Field('f_invoice_file', 'upload')
, even though I added it to the model, settings.migrate is set to True, and 
server has been restarted.

How can I do it?

[web2py] upload progress recipe not working

[cowbert]

I'm trying to do a simple manual file upload (without DAL) and display 
progress bar. I would prefer not to use any ajax helpers.
I'm trying to use the upload progress recipe (involving the cache.ram 
tracking in copystream_progress).

Here's my controller default.py:
def index():
if request.extension=='json' and 'X-Progress-ID' in request.get_vars:
cache_key = 'X-Progress-ID:'+request.get_vars['X-Progress-ID']
length = cache.ram(cache_key+':length', lambda: 0, None)
uploaded = cache.ram(cache_key+':uploaded', lambda: 0, None)
from gluon.serializers import json
return json(dict(length=length, uploaded=uploaded))
else:
form = None
patherror = False
#some checking for a valid target path for later use
if not patherror:
#generate uuid
import binascii
myuuid = binascii.hexlify(os.urandom(24))
form=FORM(INPUT(_name='file', 
_type='file'),INPUT(_type='submit', _value='Upload'))
#will do stuff to file upon form accepts
return dict(form=form, myuuid=myuuid)


views/default/index.html:

script type=text/javascript
//Add upload progress for multipart forms
jQuery(function() {
jQuery('form[enctype=multipart/form-data]').submit(function() {
//only submit once per page load
if (jQuery.data(this,'submitted')) return false;
var freq = 1000; //update every n ms
var uuid = '{{=myuuid}}'; //myuuid was generated by the controller 
above
//console.log(uuid);
var progress_url = '{{=URL(extension=json)}}';
//console.log(progress_url)
//Critical construct X-Progress-ID to request
this.action += ((this.action.indexOf('?') == -1) ? '?' : '') + 
'X-Progress-ID=' + uuid;
var progress = jQuery(
'div id=upload-progress 
class=upload-progress/div').insertAfter(
jQuery('input[type=submit]')).append(
'div class=progress-containerspan 
class=progress-infouploading 0%/spandiv 
class=progress-bar/div/div');
jQuery('input[type=submit]').remove()

progress.find('.progress-bar').height('1em').width(0).css(background-color,red);
//func to update progress bar
function update_progress_info() {
progress.show()
jQuery.getJSON(progress_url, {'X-Progress-ID':uuid, 'dummy': 
'xmlhttprequest fix for IE'}, function(data, status) {
if (data) {
var progress_percent = parseInt(data.uploaded) / 
parseInt(data.length);
var width = 
progress.find('.progress-container').width();
var progress_width = width * progress_percent;
progress.find('.progress-bar').width(progress_width);
progress.find('.progress-info').text('uploading ' + 
progress_percent * 100 + '%');
}
window.setTimeout(update_progress_info, freq);
});
};
window.setTimeout(update_progress_info, freq);
jQuery.data(this, 'submitted', true); //finaly mark form as 
submitted
});
});
/script
{{=form}}

I am getting no javascript errors but i get no progress bar and the

[web2py] Upload txt, HTML, etc and display them

[Harish Krishna]

I am building this portal where people can upload HTML files. I notice that 
the uploaded files are by default stored in the static folder with a name I 
can't make much sense out of. Now, I want people to view this HTML page on 
their browsers without having them download it. 
What is the simplest way to do this?

[web2py] Upload image using RESTful api

[iw3ijq]

Hi!

I have a SQLFORM with some filelds and an image (like example here: 
http://web2py.com/books/default/chapter/29/07/forms-and-validators#SQLFORM).

I have to populate the database using a python script. So I made a generic 
restful api:

@request.restful()
def api():
response.view = 'generic.'+request.extension
def GET(*args,**vars):
patterns = [':auto[products]',
'/products/code/{products.code}',
'/products/code/{products.code}/:field',
'/products/image_filename/{products.image_filename}',

'/products/image_filename/{products.image_filename}/:field',
   ]
parser = db.parse_as_rest(patterns,args,vars)
if parser.status == 200:
return dict(content=parser.response)
else:
raise HTTP(parser.status,parser.error)
def POST(table_name,**vars):
return db[table_name].validate_and_insert(**vars)
def PUT(table_name,record_id,**vars):
return db(db[table_name]._id==record_id).validate_and_update(**vars)
def DELETE(table_name,record_id):
return db(db[table_name]._id==record_id).delete()
return dict(GET=GET, POST=POST, PUT=PUT, DELETE=DELETE)

On python script  I use requests.post and genercs fields are ok.
I used sintax from here ( 
http://docs.python-requests.org/en/latest/user/quickstart/#post-a-multipart-encoded-file
 
). /
This upload generally work but I have a big problem:
uploading file from browser I find on DB the encoded name of file, and dhe 
file on filesystem.
Uploading from restful I find on db, instead of encoded file name, this:

'FieldStorage(''image'', ''test_image.jpg'', ''...binary data of image'')'

What's the correct way to upload a file using restful api?

[web2py] Upload file to copy.com

[Tiana A. Ralijaona]

Hi everyone,

Is there a way for a web2py app, instead of uploading a file to the server 
local file system, to upload a file to a www.copy.com account?

Thanks in advance,

Tiana R.

[web2py] upload e CASCADE delete

[maurizio]

Hi all,
probably due to my incompetence I have the following problem,
Thank's in advance anyone who wants to help me.

consider the following code:

'''
db.define_table('prodotto',
Field('nome'),
format='%(nome)s',
plural='prodotti')

db.define_table('allegato',
Field('descrizione',requires=IS_NOT_EMPTY()),
Field('documento','upload',autodelete=True),
Field('prodotto','reference 
prodotto',writable=False,readable=False),
format='%(descrizione)s',
plural='allegati')

def index():
grid = SQLFORM.smartgrid(db.prodotto,
deletable=True,
editable=True,
create=True,
csv=False)
return dict(grid=grid)

web2py 2.7.4-stable+timestamp.2013.10.14.15.16.29
(Running on Rocket 1.2.6, Python 2.7.3) Debian  7.2 (wheezy)
'''

Deleting a record from the allegato table, also delete the corresponding 
file (autodelete=True) in the default /uploads folder.
Deleting a record from the prodotto master table, also delete all records 
in the allegato detail table (CASCADE delete), but files in the folder 
uploads are not erased.

Any idea?

thanks again
Maurizio

[web2py] Upload form

A question about the upload form (Version 2.7.4):

[web2py] Upload fields custom_store

[Alan Etkin]

Supposing one has a controller like this:


def mycustomstore(f, n, p):
print file length, len(f.read())
print file name, n
print path, p

def index():
form = SQLFORM.factory(Field(myupload, upload, 
custom_store=mycustomstore))
if form.process().accepted:
pass
return dict(form=form)


Running in a welcome app and a linux machine with the rocket builtin server 
(web2py Version 2.7.4-stable+timestamp.2013.10.19.17.40.27)

When one submits the form specifying a file, the form passes validation and 
it is possible to store the file output elswhere or, for example use it as 
custom field input for a custom db interface (which is the way I'd use such 
code). Now, it seems that with this configuration, the upload feature does 
not keep a copy of the file in the filesystem (not within the application 
path afaik).

Is this the correct way of submitting file data without file storage with 
web2py? I belive this feature is not documented. Would this also work on an 
environment without write access to the file system (for example appengine)?

[web2py] upload and a process file using SQLFORM.grid

[P T]

Hello All,

Just started to learn web2py and here is an idea that I am trying to 
implement. Users creates scenarios, which includes an uploaded file. 
After the new scenario is created, the uploaded file should be processed 
and computed values written to results table. 
So far, I am successful in creating the scenarios and uploading the files. 
But, I am not sure where I would write the controller 
form.process().accepted. 
By the way, I am using SQLFORM.grid and here is complete code. Any help 
and/or pointers is highly appreciated.

-
db.py
from gluon.tools import *

db=DAL(sqlite://storage.sqlite)
auth = Auth(db)
auth.define_tables(username=True)
crud = Crud(db)

db.define_table(scenario, 
Field('title'),
Field('body', 'text'),
Field('created_on', 'datetime', default=request.now),
Field('created_by', 'reference auth_user', default=db.auth_user.id),
Field('file', 'upload'),
Field('file_status', default='file uploaded'))

db.scenario.created_by.requires=IS_IN_DB(db, db.auth_user.id)
db.scenario.title.requires = IS_NOT_EMPTY()
db.scenario.created_on.readable = False
db.scenario.created_by.readable = False

db.define_table(results,
Field('scenario_id', 'reference scenario'),
Field('amps', 'double'),
Field('volts', 'double')) 
default.py
@auth.requires_login()
def index():
   query = (db.scenario.created_by == auth.user.id)
   grid = SQLFORM.grid(query, selectable=lambda ids: [])
   return dict(grid=grid)
   
default/index.html
{{extend 'layout.html'}}
{{if auth.user.id:}}
h2Your Current Scenarios/h2
{{=grid}}
{{pass}}
--

I tested the following code and see that the form accepted is flashed. 
But, how do I link this form to the Add button in the SQLFORM.grid 
def scenario():
form = SQLFORM(db.scenario)
if form.process().accepted:
response.flash = form accepted
##get the uploaded file, process and write results
return dict(form=form)


Thanks,
PT

Hello Eduardo,

You can use db.table.insert(...) or db.table.field.store(...).

Re: [web2py] Upload image and make a thumbnail question.

[Richard Vézina]

Consider using this slice instead :

http://www.web2pyslices.com/slice/show/1666/improved-smarthumb

I can help you trouble shoot and integrate in your app...

I am the one who refactor smartthumb and set a threshold to make sure it
generate proper resized with good quality thumbnails...

[web2py] Upload field and SQLFORM.grid problem / bug?

[David Marko]

I have a table with upload field defined as follows: Field('file', 
'upload', uploadseparate=True) . When I create some items using database 
administration, the image is displayed correctly. When I involve 
SQLFORM.grid in my controller, the link to file is not correct. See two 
links below:

OK - this URL is produced by database administration interface
http://localhost:8000/periodicke_cinnosti/appadmin/download/db/item.file.8f5a1d4f8f222113.6e61747572616c6c5f30332e706e67.png

BAD - this URL is produced by SQLFORM.grid
http://localhost:8000/periodicke_cinnosti/default/form/download/item.file.8f5a1d4f8f222113.6e61747572616c6c5f30332e706e67.png

The difference is  'db' just after '/download/' in path. I'm running latest 
web2py trunk version.

[web2py] Upload field with clear text filename

[Joe Barnhart]

I'm not sure why this is difficult, but I see many posts about this when I 
search, yet none exactly work for me.  This seems like it should be easy 
but is surprisingly difficult in web2py.

I want to keep a table of uploaded files with the uploads in a blob field 
and the names in clear text in a filename field.  Like this model:

db.define_table(fileobject,
Field(filename,string,length=50,readable=False,writable=False),
Field(upload,upload,uploadfield=object_data),
Field(object_type,string,length=20,readable=False,writable=False),
Field(object_data,blob),
Field(owner,reference auth_user,default=auth.user_id,readable=False,
writable=False),
Field(saved,datetime,default=datetime.now(),readable=False,writable=
False),
Field(state,string,length=16,readable=False,writable=False),
migrate=settings.migrate)

Reading the relevant posts and the online book lead me to believe the way 
is with a controller like this one:

def index():
form=SQLFORM(db.fileobject)
if request.vars.upload:
form.vars.filename = request.vars.upload.filename
if form.process().accepted:
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)

And yet this controller does not work.  The blob is filled in but the 
filename is ignored and shows in the table as None.  In fact, form.vars 
is an empty collection and placing form.vars.filename in it does not 
produce an error, but it is ignored by the form processing.  In addition to 
the filename, I'd like to add the information about the object type etc. at 
the same point in the process, i.e. after the file has been chosen but 
before it has been loaded into the database.

I've been trying to scan through the code (I'm using 2.3.2 source) to 
answer my own questions about the upload field but it's just taking too 
much time.  The upload field is one of those parts of web2py that you 
either love or... uh... don't.  To me it seems designed for a very specific 
use model.  If my use model deviates too much then using upload is like 
pounding square pegs into round holes.  I'm tired of pounding.  Someone 
show me how to whittle off the corners of my square peg!

(You would think this would be an easy task, yet from the number of posts 
on this exact topic I know I'm in the company of a large number of others.)

[web2py] upload field without the upload

[lucas]

hello one and all,

i am doing en masse data table using xml data to a table that has an upload 
field.  the files are already present in the upload subdirectory but i need 
to populate the table with the data, including the file name that is the 
upload field.  i hope that made sense.

how do i populate the fields using a db.table_name.insert(*...***) without 
web2py wanting to actually upload the file?

thanx in advance, lucas

Re: [web2py] upload field without the upload

[Bruno Cezar Rocha]

AFAIK upload fields are just string fields, so you can insert any string there!

db.table.insert(filefield=blah)

should work!

You just have to use Python glob, os, sh or shutil to take a list of files and 
then populate the database.

Re: [web2py] upload field without the upload

[Massimo Di Pierro]

You can do it and it will work. But you will not be able to download it 
using the download action. That is because it expects a certain format 
for filenames. You will need a custom download action that would know how 
to located the file from its name.

[web2py] upload from Edit page

[ArNew]

Hi Everyone,

I need help urgently.

In my application, I am have included upload fields in Create and edit 
page. Through create page, it was very straight forward with:
td{{=form.custom.widget.attachment}}/td (View)
Field('attachment','upload',uploadfolder=os.path.join(request.folder, 
'attachments')) (DAL). 
if form.vars.attachment:
form.vars.attachment_name = request.vars.attachment.filename
id = 
thisdb.service_attachments.insert(**thisdb.service_attachments._filter_fields(form.vars))
 
.(Controller) And this works great.

That with Edit page is not the same, as it is not about editing the current 
image, but uploading more attachments. So I tried doing something like this:

input class=upload id=service_attachments_attachment name=attachment 
type=file / (view)
if request.vars.attachment != '':
form.vars.attachment = request.vars.attachment.file
filename = request.vars.attachment.filename
form.vars.attachment_name = filename
id = 
thisdb.service_attachments.insert(**thisdb.service_attachments._filter_fields(form.vars))
This follows the very similar procedure of saving the encrypted version of 
attachment name in the attachment field, but it changes the extension to 
.txt for all the attachments. It saves the attachment as 
service_attachments.attachment.b19d4ef38978e8e6.746d707437756c626f.txt 
where as the orginal attachment is photo.JPG. So ideall it should save it 
as  service_attachments.attachment.b19d4ef38978e8e6.746d707437756c626f.JPG. 

Can anyone please help me with this?

[web2py] Upload form, onvalidation and postbacks

[Andy Salnikov]

Hi, 

I have an issue with the upload form and postbacks. In my application I 
need to validate file contents before accepting it from user upload form, 
so naturally I try to use onvalidation method to it. The table used in 
the forma is defined like this:

db.define_table('input_data',
Field('input_file', 'upload', autodelete=True, 
requires=IS_NOT_EMPTY(), label=T('Input file')),
Field('output_type', default=xxx, 
requires=IS_IN_SET(['xxx', 'yyy']), label=T('Output format')),
Field('original_name', writable=False, readable=False),
Field('created', 'datetime', writable=False, 
readable=False),
)

My simplified action looks like this:

def _validateFileForm(form):
try:
validator.validate(form.vars.input_file.file)
# on success set hidden fields
form.vars.original_name = request.vars.input_file.filename
form.vars.created = datetime.datetime.now()
except Exception, ex:
# if validation fails then display an error
form.errors.input_file = T('file_validation_failed') + ': ' + 
str(ex)

def index():

form = SQLFORM(db.input_data, submit_button=T(Upload))
if form.process(onvalidation=_validateFileForm).accepted:
# save file id in a session and go to options page
session.input_data_id = form.vars.id
redirect(URL(options_odt))

return dict(form=form)

Validation seems to work OK, if file is OK then everything is redirected to 
next page, if file is bad then message is displayed in red under file 
upload field. 

What is interesting about it is that when validation fails and form is 
re-displayed it also looks like that the whole file contents is send back 
to the client together with the form. For large uploaded file this could be 
a lot of data. I see long delays and when I check the HTTP response headers 
I see many-megabytes number there. Is there a way to avoid sending the file 
contents back with the form during a postback?

Thanks,
Andy

[web2py] Upload directly to the server: error

[Paulo]

Hi!

I'm trying to create a very simple upload field, without any complex 
mechanism. A user just uploads a file to a folder in the server (apache), 
without web2py changing the file name, and without any db. I have some 
dozens of files already in a folder in the server, I just need an upload 
form to send new files easly, without having to go personally with an Usb 
Pen to the server to copy new files.

But I'm having an hard time doing it, and dont know why. With small files 
(2mb docx file) it works perfectly. But when uploading a 300mbs wav file it 
gives an error ticket:
type 'exceptions.MemoryError'

I have tried a lot of diferent ways. I have read everything I could find in 
the web. I found a topic with the same problem but no solution I could use. 
Anyone can help with some tips?

This the code in the controller:

import os

def index():
form = FORM(INPUT(_type='file',_name='myfile'),INPUT(_type='submit'))
if form.accepts(request.vars,session):

open(os.path.join(request.folder,'uploads','filename.wav'),'wb').write(form.vars.myfile.file.read())
return dict(form=form)

I have tried a lot of different ways, this only an example. I used 
SQLFORM.factory {form = SQLFORM.factory(Field('myfile', 'upload', 
uploadfolder='/static')).process()}, shutil 
{shutil.copyfileobj(request.vars.myfile.file,open(os.path.join(request.folder,'static','filename.txt'),'wb'))},
 
and a lot of different code variants but none worked. Its allways the same: 
with small files it works, with a 200mb file it gives an error.


Anyone can help me understand this problem? The max file size I need to 
upload is 500mb. It will be used by only one person, with a login, so there 
is no need to a complex mechanism, and files need to mantain the same name. 
I just need the upload to work. 

Thanks and sorry for my bad english.




I want a user to be able to upload a file to a directory in the server 
(apache), without changing the file name, and wihout databases. A simple 
and direct upload, so a friend of mine can store some files in

[web2py] Upload fields does not use Bootstrap

[Joe Barnhart]

I was just playing with automatically-generated form with an upload field 
and noticed that the button created with that field does not use the btn 
class to invoke the styling of the Bootstrap layer.  Was this deliberate or 
an accident?  Is it easily fixed by a novice CSS/JS programmer?

[web2py] Upload filename - extension maintains original case

[villas]

If I upload a file,  it is renamed as follows:

.jpg   --   new.name.abcdefgh.jpg
.JPG   --   new.name.xyzdefgh.JPG

Note that despite the renaming,  the extension maintains its original case.

I do not like this because I want all my files to be saved in lowercase.

For me it is unexpected behaviour and maybe we can change this??
If we cannot change web2py,  then how can I make sure all my file 
extensions are lowercase?

Thanks, David

 response.flash = self.T(Included.)*



But, in GAE data are inserted, but no the images are not inserted in to
blob field, in GAE web2py created picture_blob and thumbnail_blob
automatically, it works ok with SQLFORM and CRUD, but does not works with
SQLFORM.factory. I get the *_blob fields none

Someone knows about it?

Thanks

[web2py] upload file to database using curl

[thodoris]

Hello,

I have been trying to find a way of how to upload a file in a database
using curl but i can't find any references. I have found a reference
that describes how to submit text  so i  guess that uploading a file
should possible as well. What i want to do is to upload a file from my
application that is written in C++ to the web server. I am new to
web2py so i would appreciate any advice.

[web2py] upload

[lucas]

hello one and all,

i know i have a lot of posts.  i will become proficient soon.  i am
getting the hang of web2py's rythums.

i get the response.download function, it is for the server to receive
files from the client and put the files onto the server.

i want to allow the user to download files to the client computer.  so
how would i best do an upload from the server to the client.
specifically, i want to store files under static or static/pdf and
upload static files from there to the client.

thank you in advance and have a great day.  lucas

[web2py] upload field in a generic form?

[pepper_bg]

Have to go to the experts for this. I have a table for storing
arbitrary user data:

db.define_table('extra_attributes',
Field('user',   db.auth_user),
Field('name'),
Field('type', requires = IS_IN_SET(('text','file'))),
Field('value',  'string') )

'value' could be text of file. Then the controller looks like:

def upload_birth_certificate():
form = SQLFORM.factory( Field('document', 'upload', uploadfolder =
'uploads') )
if form.accepts(request.vars, session):
db.extra_attributes.insert( user=auth.user.id, name='birth
cert', type='file', value=form.vars['document'] )

Like you notice I am bending the rules a little to make the 'value'
string field hold an upload path. This all works fine, uploads my
files and all, but turns out even if I know the file name and
location, using say 
http://mysite.com/my_app/my_cont/download/uploads/no_table.document.9b6...b10.62...67.png
I can't get my files. 'download' is just the standard:

def download():
return response.download(request,db)

I can live with the uploads/no_table.document.9b6...b10.62...67.png
uploaded file name but Response.download insists on 'no_table' and
'document' being actual table/column names.

I do have my reasons to keep my schema loose like this and not define
a dedicated 'upload' field and would explore other options before
messing with the schema.

So is there any way to change this behavior? What comes to mind is
somehow fool the Field or the Form to take an existing table/column
names so Response.download is happy but I am not sure it is absolutely
safe with no side effects downstream. Put another way can 'upload'
fields be used in truly generic SQLFORM.factory(...) forms?

Thanks for your help!

[web2py] upload - file in custom folder

I have need to chose folder folder where I need to store file

Is this possible

[web2py] upload and download with multiparty filter

[miroslavgojic]

Hi,

I need to create upload and download page:
On both page there is filter what should be applied for upload or
download.
Upload form have filter with 4 drop down list and one input field for
text after this there is field for file selection and button for
upload.
I need to select some values from drop down lists and than make title
in text field and than make upload file.
Data need to bee stored in database and file should be saved in folder
but it should bee renamed in accordance to filter options.
Download have same filter but instead upload options there should be
link for file download.

Is there an example of something similar to this, I know to make my
own forms and lists, but is there some built in class and methods for
this.

Thanks

[web2py] upload/post of semi-large files

[Carlos]

Hi,

My production environment is ubuntu, postgresql, uwsgi and nginx.

The issue I'm having is when posting a form with a semi-large file (~2 mb), 
where it keeps 'resetting' the % uploaded every 30 seconds up to 2 to 3 
times, and finally failing (with no specific error that I could see).

I thought this could be fixed by setting a big number for uwsgi's harakiri 
option (which defaults to 60 secs), but that doesn't seem to help.

What should I do to fix this and allow posting forms with semi-large files 
that take about a minute or so to upload?.

Thanks!,

   Carlos

Check your nginx error log, you are probably receiving a 413 error (entity
too large). By default the limit is 1 mb

[web2py] upload - S3 storage

[Nils Olofsson]

Hi all,

 Before I go off and make an  attempt at creating a S3 upload
function, I was just wondering if anyone has a working version ?

I read the discussion on this and for me I need a way of storing
uploaded images on S3 to share between a few  VPS on Amazon's EC2.

The only other way to accomplish the same thing would be to use rsync,
which is not ideal.

I want to stay within the functionality of web2py SQLforms, maybe by
having the field type 'uploadS3' so web2py would know that the file is
going to be uploaded to amazons S3 service.

Is this a good approach ?

So far I've only used the functionality of web2py, I never had to
change or customize it, so any help or pointer would be appreciated.

Regards,

Nils

[web2py] Upload form using Load

[David J.]

I had this working a few weeks ago.

I have an upload form which I load into the page using the LOAD helper.

Right now I get an exception when I try to upload.

Here is the code.

def upload_contacts():
form = FORM(INPUT(_type='file', 
_name='data',requires=[IS_NOT_EMPTY()]), INPUT(_type='submit'))


if form.accepts(request):


contact_list = request.vars.data #I also tried 
form.vars.data.file Exception about data being a string.


...csv processing left out for brevity

I am just trying to access the file at this point.

I followed the example in the book in DAL for uploading CSV data.

[web2py] upload file without storing it

[jc]

I wish to upload a file, then process it without storing it in the
upload folder (or anywhere else on the file system). I am trying to
use the 'SQLFORM.Factory' because it gives me the nice html table of
input fields, and the normal 'if form.accepts' processing for
convenience. I thought I could persuade the form to upload and store
the file contents in 'request.vars.field.file' for processing.

Nothing I have tried so far in the field definition has allowed me to
access the contents of the file in a variable, without it being stored
to disk. Can anybody advise me what is the simplest way to achieve
this?

Thanks.

Re: [web2py] upload file without storing it

[Bruno Rocha]

request.vars.field_in_form.file

should give you the binary definition of the file, I am using it with
uploadify
