[web2py] Re: Readonly elements (select and date field) respond to clicks, allow for changes and can be submitted?
That s what readonly means. readonly is an HTML attribute and has nothing
to do with form processing. If you do not want them to appear in forms you
have to tell the model:
db.owner.own_end_date.writable = False # not writable
db.owner.own_end_date.readable = False # do not show is at all!

[web2py] Re: Undesired redirect to other page after submitting a form
Anyone has observed this as well?
Is this expected behavior?
I understood the importance of giving a formname when you're dealing with
two grids on one single page.
This however concerns one single grid per page in which case I believe the
formname is not required.
It looks however that the link associated to the redirect after submitting
a form is influenced by using the browser's back-button in the case when no
formname paramater is used in the grid.
Best regards,
Tom.

Hi,
I have some undesired behavior in my app that I was able to resolve, but I
would like to understand what goes wrong.
I could easily reproduce the problem with a simple test-application,
containing two pages and two forms (I'm skipping the boilerplate code that
is created when making a new application):
menu.py
response.menu = [
(T('Home'), False, URL('default', 'index'), []),
(T('Secondpage'), False, URL('default', 'secondpage'), []),
]
controller
def index():
form = SQLFORM.grid(db.contact, create=True, user_signature=False, )
return dict(form=form)
def secondpage():
form = SQLFORM.grid(db.activity, create=True, user_signature=False, )
return dict(form=form)
index.html
{{extend 'layout.html'}}
h1Index page/h1
{{=form}}
secondpage.html
{{extend 'layout.html'}}
h1Welcome to the 2nd page/h1
{{=form}}
db.py
contact = db.define_table('contact',
Field('first_name', 'string'),
Field('last_name', 'string'),
)
activity = db.define_table('activity',
Field('what_you_plan_to_do', 'string'),
)
The problem occurs as follows:
* I go to the index page
* I press the add button opening up the contacts form (which I don't fill
in at this point)
* In the menu I now press the link to the secondpage
* When the secondpage is loaded I press the browser's back-button
* Now I see the contacts form again which I fill in
* When I now press the Submit button, I am redirected to the secondpage as
opposed to staying on the index page, which is not the desired outcome.
I could resolve this by giving the forms a formname, but I would like to
understand why this behavior occurs.
In this specific example the undesired behavior is not critical, but it
was really a problem in my app as the redirect went to a .load page that
did not contain any css styling.
Updated controller resolving the problem
def index():
form = SQLFORM.grid(db.contact, create=True, user_signature=False,
formname='contact')
return dict(form=form)
def secondpage():
form = SQLFORM.grid(db.activity, create=True, user_signature=False,
formname='activity')
return dict(form=form)

[web2py] Re: web2py password encryption/decryption
Hello Farmy,
The code you posted helps and this examples the PHP algorithm:
http://pythonhosted.org/passlib/lib/passlib.hash.phpass.html
I recorded this in Python:
import random, hashlib
class PHPHash(object):
CHARS = '0123456789abcdefghijklmoqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
def __init__(self,secret,rounds=10):
self.secret = secret
self.rounds = rounds
def hash(self,password, salt=None):
if salt is None:
salt = ''.join(random.choice(self.CHARS) for i in range(8))
checksum = hashlib.md5(salt+self.secret).hexdigest()
for k in range(2**self.rounds):
checksum = hashlib.md5(checksum+password).hexdigest()
hashed = '$P$%s%s%s' % (chr(self.rounds+ord('0')-5),salt,checksum)
return hashed
p = PHPHash('mysecret', rounds=13)
print p.hash('mypassword')
Please check it an make sure you can reproduce the PHP passwords. Once
that's done we can try implement a custom validator, based on CRYPT that
will work with them.

Tomeu,
At the moment I'm just letting datatables.net enhance a plain html table
for me. One of these days I'll probably get around to giving it a json
datasource but so far it hasn't been a priority for my usage.
As a bonus, here's some of how to update the datatables.net display after
using the edit dialog. (So just the edited record's row in the datatable
gets updated rather than a full page refresh)
In controller
#after you'd done the necessary DB updates...
#tell browser to close the jqueryui dialog
response.js =XML( '$(#edit_dialog).dialog(close);')
#prepare for display update
edit_icon = IMG(_src=URL(c=static,f=images/page_white_edit.png),
_alt=Click
to edit)
#prep javascript code for datatables.net to update the existing row's
display
#basically just a json list of td values
row_update = simplejson.dumps([updated_record.table.first_name,
updated_record.table.last_name, updated_record.table2.name,
str(A(edit_icon, _href=URL(r=request,f='edit_loader', args=[
updated_record.table.record_id, mode]), _class=updateDialog)),
updated_record.table.email, updated_record.table.someother_id])
#using the tr#id method to update table is unreliable (the TR won't have
an id if it was added dynamically
#instead use the row index provided by datatables.net itself (we passed
it in via ajax vars)
#essentially fnUpdate(new td values, which row)
response.js += '$(#your_table_selector).dataTable().fnUpdate( '+
row_update+', '+request.vars['datatable_row_index']+',0, false );'
#also using jGrowl to give an acknowledgement
message = T(%s updated) % (updated_record.table.first_name)
response.js += '$.jGrowl('+message+');'
And as the second bonus, how to insert a brand new row in the datatable.
(Below my datatable.net is another always visible LOAD()ed form for
creating a new record. Upon submission the new record is inserted into the
existing datatable via javascript returned in web2py's response)
In controller:
#do the database insert then
#prepare for display update
edit_icon = IMG(_src=URL(c=static,f=images/page_white_edit.png),
_alt=Click
to edit)
table_update = simplejson.dumps([new_record.table.first_name, new_record.
table.last_name,
new_record.table2.name, str(A(edit_icon, _href=URL(r=request,f=
'edit_loader',
args=[new_record.table.record_id, form.vars.mode]), _class=
updateDialog)),
new_record.table.email, new_record.table.foreign_id])
#issue command for adding new row to datatable
response.js = 'vol_table.fnAddData('+table_update+');'
Good luck

[web2py] Re: web2py and self-submission/postbacks - a newcomer asks
It would probably help if you show some code, or at least explain in more
detail an example where self submission is not possible or overly
difficult. Note, your code can always distinguish between a form creation
request and a form submission request by checking whether request.post_vars
is None or whether request.env.http_method == POST.
As Jim suggested, if you are using SQLFORM, the easiest way to pre-populate
is by setting field default values *before* form creation.

I also made some of my own extensions. Extensions are allowed and
compatible.
Yet it needs more extensions. I did not push this too much because I did
not want to depart too much much from the standard.
Collection+JSON is also very verbose. I made a Collection(compact=True)
option that makes it much less verbose but will break the specs.

and you expose both:
def api():
from gluon.contrib.hypermedia import Collection

links: [{href: http://127.0.0.1:8000/super/
collections/api/attr?thing=1,.
The links field tells you how to get the attributes of the thing Chair.
For many2many and links to images you have to do a little bit more
programming. For example:
Given:
db.define_table('thing',Field('name'),Field('image','upload'))
You can define:
rules = {'thing':{'GET':{'query':None, 'fields':None,
'links':{'picture':lambda row: URL('download',args=row.image,
scheme=True)
Problem is that collection+JSON does not say anything about image uploads
(POST) and does not say anything about many2many relations.

the problem with the traditional RESTful apps on web2py is that for get the
information
of our restful example planted before, you need do three request to the
api, like this case.
patterns = [ post/{post.id},
post/{post.id}/coments[coments]/{coments.id},
post/{post.id}/coments[coments]/{coments.id}/author[auth_user]
]
parser = db.parse_as_rest(patterns, args, kwargs)
#1 GET: http://example.com/default/index/post/1.json
#2 GET: http://example.com/default/index/post/1/coments/1.json
#3 GET: http://example.com/default/index/post/1/coments/1/author.json

I added Hypermedia API support to web2py using Collection+JSON.
Experimental.
Collection+JSON is a standard for self documenting RESTful API.

What do you think about my idea ?

Thanks massimo, this is the point, generate many2many relations, with one
request get all the information relations to a resource. I'm developing a
plugin to generate great RESTful API based in many2many relations. inspired
by the Instagram API
http://instagram.com/developer/endpoints/users/#get_users.
for example :
GET: http://example.com/default/index/posts/1.json
{
data: [{
id: 1,
title: web2py,
text: testing ...,
picture: http://web2py.s3.amazonaws.com/post/my_s3_file.jpg;,
coments: [{
id: 1,
text: my coment,
author: {id:3685, name: Lebron james ...},
}, ... ]
}]
}
I'm trying do this possible, this is my implementation :

Let me add that Collection+JSON is a standard but that does not make it
perfect. I find many limitations. I managed to overcome some but utilizing
extensions.
https://github.com/mamund/collection-json/tree/master/extensions
I also made some of my own extensions. Extensions are allowed and
compatible.
Yet it needs more extensions. I did not push this too much because I did
not want to depart too much much from the standard.
Collection+JSON is also very verbose. I made a Collection(compact=True)
option that makes it much less verbose but will break the specs.

This is a automatic in Colleciton+JSON. For example:
# assume a model that described things and their attributes
db.define_table('thing',Field('name'))
db.define_table('attr',Field('thing','reference thing'),Field('name'))
and you expose both:
def api():
from gluon.contrib.hypermedia import Collection
rules = {
'thing': {
'GET':{'query':None,'fields':['id', 'name']},
'POST':{'query':None,'fields':['name']},
'PUT':{'query':None,'fields':['name']},
'DELETE':{'query':None},
},
'attr': {
'GET':{'query':None,'fields':['id', 'name', 'thing']},
'POST':{'query':None,'fields':['name', 'thing']},
'PUT':{'query':None,'fields':['name', 'thing']},
'DELETE':{'query':None},

return Collection(db).process(request,response,rules)

{collection: {version: 1.0, href: /super/collections/api/thing,
items: [{href: http://127.0.0.1:8000/super/
collections/api/thing/1/chair, data: [{prompt: Id, name: id,
value: 1}, {prompt: Name, name: name, value: Chair}],
links: [{href: http://127.0.0.1:8000/super/
collections/api/attr?thing=1,.
The links field tells you how to get the attributes of the thing Chair.
For many2many and links to images you have to do a little bit more
programming. For example:
Given:
db.define_table('thing',Field('name'),Field('image','upload'))
You can define:
rules = {'thing':{'GET':{'query':None, 'fields':None,
'links':{'picture':lambda row: URL('download',args=row.image,
scheme=True)
Problem is that collection+JSON does not say anything about image
uploads (POST) and does not say anything about many2many relations.

[web2py] /default/user/login not honoring _next anymore?
In the current head branch in github (Version 2.9.5-trunk+timestamp.2014.06.19.17.16.40), it seems that the /default/user/login form does not use the _next variable specified in the URL. For example, The myapp/default/view is decorated with @auth.requires_login(), so when I am not logged in, it triggers web2py's login form with this URL: https://server-name:4443/myapp/default/user/login?_next=/myapp/default/view%3Fapp%3Dnextapp However, the variable _next in the form is always: input type=hidden value=/myapp/default/index name=_next I would expect it to be: input type=hidden value=/myapp/default/view?app=nextapp name=_next Is this a potential bug or is this an expected change?

[web2py] Re: Readonly elements (select and date field) respond to clicks, allow for changes and can be submitted?
I did what you suggested but the calls to:
db.owner.own_end_date.writable = False # not writable
db.owner.own_end_date.readable = False # do not show is at all!
are effective only if executed before the call to form =
SQLFORM.smartgrid(db.owner, ...
When executed after, have no effect.
I want to make db.owner.own_end_date not writeable conditionally:
...
...
if ((len(request.args)1) and (request.args(1)=='edit')):
if (form.element('input',_name='own_end_date')['_value']!=''):
db.owner.own_end_date.writable=False # - no effect
...
...
If the edited record contains a date value in that field then user must not
change it. How can I make that field not writeable in such a case?
Thanks

[web2py] IS_IN_SET options list separator
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi,
Is there a way to introduce a separator in IS_IN_SET options widget, so that
from code like:
IS_IN_SET( ('1', 'First'), (seperator?), ('2', 'Second'),'3', 'Third') )
it produces something like this?
select
option value=1First/option
option disabled_/option
option value=2Second/option
option value=3Third/option
/select
Thanks,

[web2py] Re: Trying to use the LOAD helper, if a button is clicked
Looks like the new datatables.net v1.10 has a new API so there are now
probably better ways to do this than I showed.

Tomeu,
At the moment I'm just letting datatables.net enhance a plain html table
for me. One of these days I'll probably get around to giving it a json
datasource but so far it hasn't been a priority for my usage.
As a bonus, here's some of how to update the datatables.net display
after using the edit dialog. (So just the edited record's row in the
datatable gets updated rather than a full page refresh)
In controller
#after you'd done the necessary DB updates...
#tell browser to close the jqueryui dialog
response.js =XML( '$(#edit_dialog).dialog(close);')
#prepare for display update
edit_icon = IMG(_src=URL(c=static,f=images/page_white_edit.png), _alt
=Click to edit)
#prep javascript code for datatables.net to update the existing row's
display
#basically just a json list of td values
row_update = simplejson.dumps([updated_record.table.first_name,
updated_record.table.last_name, updated_record.table2.name,
str(A(edit_icon, _href=URL(r=request,f='edit_loader', args=[
updated_record.table.record_id, mode]), _class=updateDialog)),
updated_record.table.email, updated_record.table.someother_id])
#using the tr#id method to update table is unreliable (the TR won't have
an id if it was added dynamically
#instead use the row index provided by datatables.net itself (we passed
it in via ajax vars)
#essentially fnUpdate(new td values, which row)
response.js += '$(#your_table_selector).dataTable().fnUpdate( '+
row_update+', '+request.vars['datatable_row_index']+',0, false );'
#also using jGrowl to give an acknowledgement
message = T(%s updated) % (updated_record.table.first_name)
response.js += '$.jGrowl('+message+');'
And as the second bonus, how to insert a brand new row in the datatable.
(Below my datatable.net is another always visible LOAD()ed form for
creating a new record. Upon submission the new record is inserted into the
existing datatable via javascript returned in web2py's response)
In controller:
#do the database insert then
#prepare for display update
edit_icon = IMG(_src=URL(c=static,f=images/page_white_edit.png), _alt
=Click to edit)
table_update = simplejson.dumps([new_record.table.first_name, new_record.
table.last_name,
new_record.table2.name, str(A(edit_icon, _href=URL(r=request,f=
'edit_loader',
args=[new_record.table.record_id, form.vars.mode]), _class=
updateDialog)),
new_record.table.email, new_record.table.foreign_id])
#issue command for adding new row to datatable
response.js = 'vol_table.fnAddData('+table_update+');'
Good luck

I see that you use datatables.net. Do you use some plugin o directly
you pass json from controller?
I want use in a new project but i have doubts have to implement. Can you
give me some idea?
