[Dirk Krause]

I have to apologize for my stupid question.

Of course web2py *does* deliver raw html. But AngularJS uses the same 
brackets convention as web2py - that's what caused the conflict (I should 
write a book: 'The Art of Reading Error Messages' ... *facepalm*)

There seems to be a workaround, since you can change the markup in angular 
according to this:
http://stackoverflow.com/questions/8302928/angularjs-with-django-conflicting-template-tags

I'll try this next.

[web2py] Rendering 'raw' HTML for AngularJS with Web2py

[Dirk Krause]

Hi,

I am trying to use web2py to manage a database and display the resulting 
JSON in AngularJS.  To render an angular compatible view I need to pass raw 
html in a view (for example the html needs to start with '' 
and so forth). Of course I could place the files in the static folder, but 
then I can't protect the files via @auth.requires_login() etc.

What would be the best way to achieve that?

Thank you,
  Dirk

[web2py] Re: How do I use web2py to make a simple GUI?

[Dirk Krause]

my two cents:
as long as you don't need web services (and you don't if I understood you 
correctly) you are probably better off with a JavaScript framework without 
a server component (i.e. without web2py).

The AngularJS framework is one of many frameworks that come with good 
documentation. I'd recommend digging into these examples, if you want to go 
this way:
http://rabidgadfly.com/2012/12/angularjs-simple-calculator/
The example there also works on mobile devices.
Also: http://docs.angularjs.org/tutorial/

[web2py] Re: MARKMIN line break

[Dirk Krause]

I learned from my editor that there is a huge difference between a 
paragraph and a line break. This also documented on a different thread here 
- people writing texts need both.

Sure. I could take what you wrote down there, test it on Heroku, verify

[web2py] Re: MARKMIN line break

[Dirk Krause]

I see, and thank you. Now we already have a database full of text without 
the 'newline' tag and I have two options:
(1) traverse through the database and applying foresaid regex to all text 
fields or
(2) hack the regex somewhere into the code.

I just tried (2) and it seems to be working; I applied this:
{{=MARKMIN(re.sub(r'([^\n])\n([^\n])', r'\1[[NEWLINE]]\n\2', theText))}}
and it seems to be working.

So that's ok now, but when I do a CSV export it's not in so I my guess is I 
need to change the MARKMIN renderer itself, right?

[web2py] Re: MARKMIN line break

[Dirk Krause]

ok, thank you.

I am only wondering why there is a special tag '[[NEWLINE]] when there is 
already a one-to-one token for it - the single page break itself.
This can be parsed with
re.sub(r'([^\n])\n([^\n])', r'\1[[NEWLINE]]\n\2', s)
(full example here: http://pythonfiddle.com/replace-single-line-break )

Where would I put this regular expression best to avoid the newline tag for 
the editor?

Thanks again.

[web2py] MARKMIN line break

[Dirk Krause]

Hi,

sorry if this was answered elsewhere but I couldn't find it:
I found no consistent answer how to add single line breaks ('') as 
opposed to paragraphs ('') into MARKMIN.

This is what I found so far:
(1) the 'purest' Markdown doesn't allow line breaks at all (found in 
stackoverflow)
(2) there is a common practice to add two or more spaces at the end of the 
line to inject a  (see http://goo.gl/iEGU).
(3) then there is github flavored markdown 
(http://github.github.com/github-flavored-markdown/ ) which simply adds 
this to the renderer.

Obviously the MARKMIN renderer doesn't support (3). From some forum posts I 
thought it would support (2) but it doesn't (I checked on version 2.0.9).

What is the best practice to achieve single line breaks?

Thanks,
  Dirk

[web2py] Form upload with cURL

[Dirk Krause]

Hi,

I finally figured out to do a file upload via curl (may be obvious to 
everybody else, but not to me ...) so here we go:

I followed the 'manual file upload' example over at web2pyslices (thanks, 
Yarin!):
  http://www.web2pyslices.com/slice/show/1504/manual-uploads

Just for clarity I changed the table name and the field names to 't_*' and 
'f_*' (which I consider a best practice).
I added this to the model ...
db.define_table('t_image',
Field('f_title'),
Field('f_file', 'upload'),
format = '%(title)s')

... and this to the controller ...
@auth.requires_login()
def index():
image_form = FORM(
INPUT(_name='image_title',_type='text'),
INPUT(_name='image_file',_type='file')
)

if image_form.accepts(request.vars,formname='image_form'):

image = db.t_image.f_file.store(image_form.vars.image_file.file, 
image_form.vars.image_file.filename)
id = 
db.t_image.insert(f_file=image,f_title=image_form.vars.image_title)

images = db().select(db.t_image.ALL)

return dict(images=images)
... and this to the view.

{{extend "layout.html"}}
 






 

{{for image in images:}}



{{=image.f_title}}


[Download]


{{pass}}



The applications name was 'upload' so the corresponding cURL call would be:
curl --user user:pass --form "image_title=some name" --form 
"_formname=image_form" --form "image_file=@test.png" --form Submit=OK http:
//127.0.0.1:8000/upload/default/index
(with user:pass being substituted with a valid username/password 
combination and test.png sitting in the same directory)

I hope this saves somebody some time.

This doesn't work for the SQLFORM.smartgrid forms unfortunately since they 
sport a '_formkey' parameter which changes every time you call the form. 
 If someone knows a solution to this, I'd be happy to learn it.

[web2py] grid/smartgrid field editability

[Dirk Krause]

Is there an (easy) way to disable the editability of distinct fields in a 
grid/smartgrid?

I'd like to create a view for an editor (being able to edit all fields), 
and an approver (being able to just view all fields, and change only one 
field like a checkbox).

Thanks, Dirk

[web2py] Re: web2py 2.0 almost done

[Dirk Krause]

If you want the trunk (i.e. the latest version) I assume it's best that you 
do a 
git clone https://github.com/web2py/web2py/
and work from there.
Every once and a while you will want to do a
git pull
to receive the latest version.

[web2py] Re: web2py 2.0 almost done

[Dirk Krause]

Sry if this is a dumb question: am I supposed to post possible bugs here or 
file an issue on google code?

Re: [web2py] Re: web2py hangs while creating the mysql tables

[Dirk Krause]

I finally understand why the app wizard prefixes every table with 't_' and 
every field with 'f_'.  Probably a good practice anyway.

[web2py] RESTful services with curl and/or python

[Dirk Krause]

Hi,

I tried to pull together the different sources for restful services, 
including various hints in this group and of course the excellent web2py 
documentation. If this is the wrong place or info, feel free to move or 
delete it.

Here's how you create a restful web2py application in under 2 minutes:
- create a wizard application called 'RT'
- add a table named 'entries' and add a field 'entry wiki'
- finish the wizard with all the default values
- register a user 'user' with password 'pass'
now you have an application with 10 random entries.

The next two step are required due to a bug that I filed before 
(http://goo.gl/CPO0G)
- go to the design page of the app and change the table name from 
't_entries' to 'entries'
  in db_wizard.py (4 times) and in default.py (1 time)
- check that the application is still working. you notice that the table 
now is empty since we changed
  the name of the table.
- Add a couple of entries.

- now add the RESTful services to the controller as described in 
http://goo.gl/iITNd ('parse_as_rest') 
  or here: http://goo.gl/ltfa2

@request.restful()
def api():
response.view = 'generic.'+request.extension
def GET(*args,**vars):
patterns = 'auto'
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).update(**vars)
def DELETE(table_name,record_id):
return db(db[table_name]._id==record_id).delete()
return locals()


- In the browser:
  you get all entries with
  http://127.0.0.1:8000/RT/default/api/entries.json

  you get the just the second entry with
  http://127.0.0.1:8000/RT/default/api/entries/id/2.json

  you get all auto-generated patterns with
  http://127.0.0.1:8000/RT/default/api/patterns.json

That's as far as we get with GET in a browser.

To make things more realistic, we add basic user authentication and try 
some POSTs with curl.
- Add 
auth.settings.allow_basic_login = True
@auth.requires_login()

  above @request.restful. Authentification now is mandatory for the REST 
interface.

- get the first entry
  curl --user user:pass 
http://127.0.0.1:8000/RT/default/api/entries/id/1.json

- post a new entry
  curl --user user:pass -d "f_entry=something" 
http://127.0.0.1:8000/RT/default/api/entries.json

- delete the first entry
  curl -X DELETE --user user:pass 
http://127.0.0.1:8000/RT/default/api/entries/1.json


Same thing from python:

import requests
from requests.auth import HTTPBasicAuth 
payload = {'f_entry': 'somevalue'}
auth=HTTPBasicAuth('user', 'pass')
r = requests.post("http://127.0.0.1:8000/RT/default/api/entries.json";, data=
payload, auth=auth)
r = requests.delete("http://127.0.0.1:8000/RT/default/api/entries/1.json",data
=payload, auth=auth)

[web2py] Markmin patch with nested lists

[Dirk Krause]

Hi,

I am trying to apply this patch:
http://code.google.com/p/web2py/issues/attachmentText?id=524&aid=5240002000&name=markmin_nested_list.diff&token=kjJqRhq0Kmpw7px0Idciodnzvyo%3A1343665747008
(IIRC Massimo posted this somewhere here.)

I successfully patched it to the markmin2html.py file, but I don't see any 
changes. Do I need to restart something to see the changes working?

Thanks,
Dirk
