It's not feasable at all. Thing is, wxPython is a python bindings to 
wxwidgets, which is a c++ gui framework.  The browser will not know how to 
handle them, this is on purpose.  The browser itself does all the actual 
rendering of widgets from within its html engine, the browser should not know 
about wxwidgets, even if it itself is written in wx, this way.

Don't let how the code is written fool you. wxpython is not going to work the 
way you think it is.  Browsers for security reasons do not execute random code 
and you can not send the widgets over the network that way, You'll need to 
rewrite the gui code.

best way to define a many-to-one relationship using FreeRadius' existing DB schema

[yolabingo]

Thanks in advance for any insight or suggestions.

I have a simple web interface for a freeradius mysql database.  It
uses the Django admin interface exclusively, and makes it simple to
manage Radius usernames, passwords, preferences etc, which we use for
authentication on WiFi hotspots.

My question - how can I best use "models.ForeignKey" to associate
freeradius accounting data with the "WifiUser" I am using to manage
radius usernames/passwords/etc?

Here's a portion of the WifiUser model:

class WifiUser(models.Model):
username =  models.CharField( max_length=64,
unique=True )
password =  models.CharField( max_length=64 )
# Radius attributes -see http://coova.org/CoovaChilli/Proxy#toc6
session_timeout = models.CharField( max_length=64, blank=True,
default='21600' )
# These point to entries in freeradius db tables
   radius_password = models.OneToOneField(RadiusPassword,
editable=False)
   radius_session_timeout = models.OneToOneField(RadiusSessionTimeout,
editable=False)

I then use Signals to update the appropriate freeradius db tables as
necessary (e.g., WifiUser.password is changed, the new value is also
stored in WifiUser.radius_password.value) - it works great, thank you
Django.

What I would like to do is have access to a WifiUser's radius
accounting data via the Django Admin interface.
This table looks like:

CREATE TABLE `radacct` (
`radacctid` bigint NOT NULL PRIMARY KEY,
`username` varchar(192) NOT NULL,
 bunch of cool radius info logged per session
 --snip--
So the radacct.username ==  WifiUser.username - but that is all I've
got to associate these two tables.

Can I set up some customized version of this Many-to-One relationship
-
class RadiusAccounting(models.Model):
wifiuser = models.ForeignKey('WifiUser')

in which I specify that "RadiusAccounting.username ==
WifiUser.username" instead of
"RadiusAccounting.wifiuser_id == WifiUser.id:  -- thus reaping the
benefits of a normal ForeignKey relationship?

Todd

Re: Need help: request.POST.copy() ?

[Sam Walters]

Yes, Id really need to see some code to work it out.

A bit hard to work out wether you're returning the request.POST.copy()
and wether this is instantiated in a new form instance and returned.
Eg: if form validation fails.
Or wether you are  having trouble redisplaying the original
request.POST data in a new form or one thats failed evaluation?

Once again would need to see the some code.

Hmm, dont forget:
http://en.wikipedia.org/wiki/Pass_by_reference

Here is some of my basic code... eg: adding a new param 'IP address'
to request.POST form data for evaluation. This might help.

def contact(request):
from hvv.contact.forms import ContactEmailForm
#form validation: Note: ip address is not form data, is validated
as form and added to formdata by 'getIpAddr()'
if request.is_ajax() and request.POST:
#Note: copy() makes QueryDict Mutable
data = QueryDict(request.POST['form']).copy()
data.update({'ipaddress': getIpAddr(request) })
form = ContactEmailForm(data)
if form.is_valid():
n_email = form.cleaned_data['email']
n_subject = form.cleaned_data['subject']
n_message = form.cleaned_data['message']
n_ipaddr = form.cleaned_data['ipaddress']

saveInDb(n_email, n_subject, n_message, n_ipaddr)
sendEmail(n_email, n_subject, n_message, n_ipaddr)

return render_to_response('contact.html', {
'form':ContactEmailForm(), 'message':'Thankyou. Your message was
sent!.' }, context_instance=RequestContext(request))
else:
return render_to_response('contact.html', { 'form':form },
context_instance=RequestContext(request))
form = ContactEmailForm()
return render_to_response('contact.html', { 'form':form },
context_instance=RequestContext(request))

cheers

Re: WxPython and django

[Aref Nammari]

Hi Calvin,  I think that there is some misunderstanding about what my
question was about. Let me try to clarify. Wxpython is a module which is run
just like any other python module. It is great for rendering forms, widgets,
frames etc...and it has within it an html module. You can embed wxpython
within html code.
Since wxpython is a python module and if you can run python code in django
apps then you should be able to run wxpython code provided the right modules
are imported--just like any other python module. What I was thinking of
doing is either embed some wxpython code within html to render the different
pages of the django app or call wxpython functions from the html template.
All the code resides on the server of course. The user interacts with the
app through the web page. So the forms would be rendered by wxpython instead
of html. I don't know if this is clearer or if what I am thinking of is
feasible at all.

Re: Need help: request.POST.copy() ?

[hank23]

Sorry the last example I gave maybe wrong. I think I'm actually
getting the data back out using the cleaned_data. I'm trying to do
this from memory, since this is a work problem and I've been
struggling with it since the middle of this afternoon and it's been
very frustrating.

Re: Need help: request.POST.copy() ?

[hank23]

Currently I have logic in place that makes a copy of request.POST so
it can put data from a record using a key, gotten from the previous
bunch of POSTed data, on the screen for display purposes. This all
works fine. But when I go in and alter some of the data being
displayed then the next time I submit the form the data that I just
entered is not displaying in the request.POST dictionary when I look
at it. So what am I apparently not doing right to cause the data to be
lost? I display the data to the screen after making a copy of
request.POST (request.POST.copy()) like this:

request.POST['title'] = record.title

I actually call sub views from the main view which processes this
screen, display the data as shown above as well as capture the changes
to the request.POST dictionary like this:

title = request.POST['title']

After trying to capture the data this way then I try to write it to
the database, but nothing new is being saved, so that's why I'm
wondering why no new data  is being saved.

Re: Need help: request.POST.copy() ?

Hi hank23
request.POST would be immutable.

"QueryDict instances are immutable, unless you create a copy() of
them. That means you can't change attributes of request.POST and
request.GET directly."

I dont know what you mean by side-effect.

I copy/instantiate querydicts all the time never had any problems.
Dont forget if you can use python to clone objects :)

Need help: request.POST.copy() ?

[hank23]

I need to know when I can or should use request.POST.copy() when
processing screens, as opposed to when not to use it. I've used it
some, on one screen in particular, which seems to work fine for
displaying the data that I want to display, when I put the data on the
screen programatically from within a view. However when I try to alter
the data manually by keying it in from my keyboard, or selecting an
option from a dropdown, nothing seems to show up changed the next time
that submit the form to the view and look at the data posted. So I'm
wondering if there is something else going on or if this problem is
some kind of side effect of using request.POST.copy()?

Errors or warnings? There's a big difference. Errors mean it isn't
working. Warnings mean it is working, but something is telling you to
pay attention to something.

> Can one return an image in any other way?

Sure. Write a view that returns the content. It's 3 lines of code (a
couple more if you count imports and whitespace). Added bonus -- it's
actually more efficient than serve(), because it doesn't impose a disk
access overhead every time it gets called.

TRANSPARENT_1_PIXEL_GIF =
"\x47\x49\x46\x38\x39\x61\x01\x00\x01\x00\x80\x00\x00\xff\xff\xff\x00\x00\x00\x21\xf9\x04\x01\x00\x00\x00\x00\x2c\x00\x00\x00\x00\x01\x00\x01\x00\x00\x02\x02\x44\x01\x00\x3b"

Serve a tracking pixel via Django

[Adam Nelson]

We have one static file that needs to be served after business logic has run 
(i.e. log a view on a specific url based on a unique code).  We used to use 
serve() in production.  This has always been frowned upon but with Django 
1.3, the errors are worse.  Can one return an image in any other way?

Add to the bottom of the file that defines TranslationForeignKey:
replace my_app.fields  with a that matches the definition
try:
from south.modelsinspector import add_introspection_rules
add_introspection_rules([], ['^my_app\.fields\.TranslationForeignKey'])

I think i found the source of all problems

I am not a python expert, so I was wondering if anybody can tell me what
this code means

// beginning of code

*from django.db import models


class TranslationForeignKey(models.ForeignKey):
"""
"""
pass
*
// end of code

This piece of code has been generating an error when executing the *python

If the above code has doesn't do anything, I will comment it out

Any other suggestions would be great

Re: south for django

[jay K.]

that's weird, because I keep getting the same error

the field that I'm using is not custom (models.TextField)

it may be located somewhere else

Re: south for django

[jay K.]

All I did to change my models.py, was to add the following line

*map_text = models.TextField( 'Map text', blank = True, null = False,
help_text = 'text on the subpage "map"')*

As you can see, I intend to add a new text area in my models.py

At the bottom of the page, I type this code

*from south.modelsinspector import add_introspection_rules
add_introspection_rules([], ["^destinations\.map_text"])*

The name of my application is "destinations" and the new field is called
"map_text"

Unfortunately it stills gives me the same error message

Strange admin changelist bug with list_editable and FK to User in 1.2.3

[Nan]

Hi folks...

I've got a model that looks roughly like so:

class Account(admin.ModelAdmin):
type = models.ForeignKey(AccountType, help_text='Type of account.
Determines what features are available to the user.')
user = models.ForeignKey(User, unique=True, primary_key=True)
design = models.ForeignKey(Skin, blank=True, null=True)


And a ModelAdmin that looks like so:

class AccountAdmin(admin.ModelAdmin):
list_display = ['__unicode__', 'user', 'type', 'design', ...]
list_editable = ['type', 'design', ...]

The User column is showing up blank in the admin changelist
(containing nothing but a hidden form field).  I've tried eliminating
other options on the AccountAdmin, changing field order, and narrowed
it down to some sort of odd interaction with list_editable.
Commenting out the list_editable property entirely fixes the problem,
but any value (even an empty list) for list_editable that does not
include 'user' causes the problem to recur.

Any idea what might be going on?  I'm using 1.2.3 at the moment, and
the client doesn't want to authorize the work to upgrade to 1.3 just
yet, so I can't determine whether it's version-specific.

Thanks.

south for django

[jay K.]

hello,

I've downloaded and installed south successfully to manage changes
with my models.py file

I type the following command

*python manage.py schemamigration myApp --auto*

then, get the following message

*You cannot use --auto on an app with no migrations. Try --initial.*

So I do as stated, with the command: *python manage.py schemamigration myApp
--initial*, but get the following message:

*Cannot freeze field*

what's wrong?

idiotic foreignkey error

[Nick]

I have a model with 3 foreignkeys to another model. This has never
been an issue for me before but now it's throwing an error:

 has more than 1

My model looks like this:

a_race = models.ForeignKey('Race', related_name='arace', blank=True)
b_race = models.ForeignKey('Race', related_name='arace', blank=True)
c_race = models.ForeignKey('Race', related_name='arace', blank=True):

I must reiterate that this has never been a problem for me before.

I don't know if this is the best way to do it (change the QuerySet), but I

want to write "Other" as the last  to choose.

Re: Dynamically generating form fields

[Andre Terra]

I've been fighting to get this to work for me to. I can point you to a few
articles that are helping me achieve what I want. There's some black magic
involved, but once you play with the code for a while you'll know what it
does.

These are some VERY good links with info that should definitely be included
in the docs. Good luck and I apologize for not answering sooner. My use case
is different from yours, so pasting my code probably won't be that useful to
you.

Use South for your database migrations:
http://south.aeracode.org/

Otherwise you have to write raw SQL statements to modify the database,
or delete the entire database and use syncdb to re-create it to match
you model.

I think South is the best of those options.

Re: new text area in django admin page

[jay K.]

that right, I've provided a very vague question

I have to modify an existing models.py file. What I basically want to do is
to add
a new Text Area in the django admin page so I can add a new subpage.

Here is what I do step by step

1) I open models.py and insert the following code:

// start of code

*class City( models.Model ):

   
   class Translation (multilingual.Translation):
 ...
 climate_text = models.TextField ( 'Climate text', blank = True,
null = False, help_text = 'text on the subpage "clima"' )
 map_text = models.TextField( 'Map text', blank = True, null =
False, help_text = 'text on the subpage "map"')
*

// end of code

The code in bold and italics is the text area I want to add to my models.py.

Then, I update my database by executing the following code:

python manage.py sql *my-application*

However, when I refresh my website, I get an *Error 505. *This error appears
only in the pages that use
the models.py file I've modified, so the rest of the website works fine.

So what am I doing wrong?

Thanks

Sorry, I couldn't answer earlier, but yes - that is exactly what you
should do. Class-based views can't be referenced by using dot
notation, so you must name them and reverse them by name.

Django expects a string in form of ".". A
class-based view is not a module, so it has no chance of success. Even
if it somehow was able to get the as_view method from the class, there
is no way to tell to which URL it was bound (look at how as_view()
works for more details).

Naming all your URLs is a good practice anyway.

Re: Dajax, what do you think about it?

[LJ]

My opinion would be to add it in.  But, I am not as experienced with
Dajaxice as others may be.  I just know it took me a long time to
figure out how to manually add it and get it working.
It wasn't until I learned how to use virtualenv that I was able to get
Dajaxice installed and working correctly.

Screen Fields and Dropdowns Not Capturing Changes To Data on Edit Screen

[hank23]

I have a screen with a form on it and the text fields values and the
dropdown box selected values that are changed do not appear to be
posted back to the view. How is this possible? When I go to the screen
originally I see all of the data that supposed to be there (often
times much of it is from the previous screen). But when I physically
go in and touch any of the text fields or select a different entry
from a dropdown, the values which appear to be posted  back to the
view are still the original values that the screen was originally
displayed with.

Re: authentication switching mid-session

[Chris Curvey]

there's no cacheing in front of the application server, if that's what 
you're asking.  The app server does do some cacheing on its own, but not

 What do you mean by that ? Do you mean the {% url %} template tag, or
 the `url` function commonly used in urls.py module. Give us some

Re: about url tag

I mean url tag: {% url ... %}

this is what I am using: Leer
mas...

directory structure:

site
  |--> url.py
  |--> apps (included in the python path)
|--> help
   |--> models.py
   |--> views.py
   |--> urls.py

where:
"apps" is a package (is in the python path)
"help" is my application
"HelpSubject" is a class based view, here is the definition:


class HelpSubject(DetailView):
template_name = 'help/help_subject.html'
context_object_name = 'help_subject'
queryset = HelpSubject.objects.filter(published=True)

and here is the two lines in url.py and apps/help/url.py

url.py:
(r'^help/', include('help.urls')),

apps/help/url.py:

about url tag

[Lic . José M . Rodriguez Bacallao]

hi folks, I was using django 1.2.5 and generic views to some simple
things, now, I upgrade to django 1.3 and I am trying to use the tag:
url but it doesn't seems to work with django class based generic
views. How to use this tag correctly?

Before asking a question, have a think about what you actually want to ask. 
Then think about whether you're providing all the information needed for 
anyone to answer the question. Now look at what you've written. Do you 
seriously, honestly think that anyone will have the remotest idea what 
you're asking, or be able to even start answering you?

Re: staticfile app question

[Micah Carrick]

I had to look up "grok". Guess I'm out of the loop.

Anyway, one other pitfall with using absolute URLs in CSS is that you can
break SSL (https) when you have common CSS for both the SSL and non-SSL
pages. So watch out for that. IMO, relative URLs are preferable in external
stylesheets. In fact, that has been a firm rule in most projects I've been
involved with.

Hi there,

I think that you would need to get the count of votes for each poll, add all
votes and use the formula:

vote_percentage = (poll_votes/total_poll_votes)*100

Re: Hi multilingual charfields?

[Stuart MacKay]

One more vote for django-transmeta, 
http://code.google.com/p/django-transmeta/, it's really simply to use. I 
have used in a project for names and small sections of text. The admin 
integration is nice as it allows you to view the fields side-by-side so 
it makes the process of translation easy to do.

EuroPython 2011: call for paper is ending - Please spread the word

[Palla]

Hi all Django users,
I'm Francesco and I am writing on behalf of "Python Italia APS", a no-
profit association promoting EuroPython conference.
(www.europython.eu)

Europython End of Call for Presentations is April 6th. I'd like to ask
to you to forward this mail to anyone that you feel may be interested.

We're looking for proposals on every aspects of Python: programming
from novice to advanced levels, applications and frameworks, or how
you have been involved in introducing Python into your organisation.

**First-time speakers are especially welcome**; EuroPython is a
community conference and we are eager to hear about your experience.
If you have friends or colleagues who have something valuable to
contribute, twist their arms to tell us about it!


Presenting at EuroPython

We will accept a broad range of presentations, from reports on
academic and commercial projects to tutorials and case studies. As
long as the presentation is interesting and potentially useful to the
Python community, it will be considered for inclusion in the
programme.

Can you show the conference-goers something new and useful? Can you
show attendees how to: use a module? Explore a Python language
feature? Package an application? If so, consider submitting a talk.


Talks and hands-on trainings

There are two different kind of presentations that you can give as a
speaker at EuroPython:

 * **Regular talk**. These are standard "talk with slides", allocated
in slots of 45, 60 or 90 minutes, depending on your preference and
scheduling constraints. A Q session is held at the end of the talk.
 * **Hands-on training**. These are advanced training sessions for a
smaller audience (10-20 people), to dive into the subject with all
details. These sessions are 4-hours long, and audience will be
strongly encouraged to bring a laptop to experiment. They should be
prepared with less slides and more source code. If possible, trainers
will also give a short "teaser talk" of 30 minutes the day before the
training, to tease delegates into attending the training.

In the talk submission form, we assume that you intend to give a
regular talk on the subject, but you will be asked if you are
available for also doing a hands-on training on the very same subject.

Speakers that will give a hands-on training are rewarded with a **free
entrance** to EuroPython to compensate for the longer preparation
required, and might also be eligible for a speaking fee (which we
cannot confirm at the moment).

Topics and goals

Specific topics for EuroPython presentations include, but are not
limited to:

- Core Python
- Other implementations: Jython, IronPython, PyPy, and Stackless
- Python libraries and extensions
- Python 3.x migration
- Databases
- Documentation
- GUI Programming
- Game Programming
- Network Programming
- Open Source Python projects
- Packaging Issues
- Programming Tools
- Project Best Practices
- Embedding and Extending
- Science and Math
- Web-based Systems

Presentation goals usually are some of the following:

- Introduce audience to a new topic they are unaware of
- Introduce audience to new developments on a well-known topic
- Show audience real-world usage scenarios for a specific topic (case
study)
- Dig into advanced and relatively-unknown details on a topic
- Compare different options in the market on a topic


Community-based talk voting
---
This year, for the first time in EuroPython history, the talk voting
process is fully public. Every partecipant gains the right to vote for
talks submitted during the Call For Papers, as soon as they commit to
their presence at the conference by buying a ticket. See all the
details in the talk voting[1] page.

Contacts

For any further question, feel free to contact the organizers at
i...@pycon.it. Thank you!

Re: WxPython and django

[Aref Nammari]

Calvin,

The database as well as the django app sits on a server
(internal--this is not meant for public access by the general public).
To access the app users would have to login to the server through http
and run the app from there.

Re: How to disable default authentication/messaging system?

[sanderkrause]

In addition to my last message, I have also tried specifying the apps
with the project name in front of it:

'uninspiring.auth'

instead of just 'auth' in order to prevent confusion that the
specified 'auth' module is in fact my own. I don't really want to go
through the process of renaming the module just because of this issue,
as it is the most appropriate name that I can think of. Any solutions,
anyone?

Re: WxPython and django

[Calvin Spealman]

Aref,

The question I would have is where your database sits. Is it supposed
to sit on a central server? In a website, your database only needs to
be accessed by machine rendering the pages. If you want the same
database talking to desktop applications, you need to let those apps
talk to the database or run the database on individual users'
machines. This is the part that concerns me, especially giving those
users access to a central DB.

wsgi configuration

[yongzhen zhang]

Hi,
I am using apache + wsgi for my Django project. But now i am a bit
confused. The project is under /home/yongzhen/workspace/www . I put
the apache folder under www, and it is same level with the project
"iStore". i write django.wsgi inside apache like this:
import os
import sys
path='/home/yongzhen/workspace/www/iStore'
if path not in sys.path:
sys.path.append(path)

wsgi_dir=os.path.abspath(os.path.dirname(__file__))
project_dir=os.path.dirname(wsgi_dir)
sys.path.append(project_dir)
project_settings=os.path.join(project_dir,'settings')
os.environ['DJANGO_SETTINGS_MODULE']='www.iStore.settings'

import django.core.handlers.wsgi
application=django.core.handlers.wsgi.WSGIHandler()

But it does not work, the apache has the following error:
 mod_wsgi (pid=11619): Exception occurred processing WSGI script '/
home/yongzhen/workspace/www/apache/django.wsgi'.
 Traceback (most recent call last):
  File "/usr/local/lib/python2.6/dist-packages/django/core/handlers/
wsgi.py", line 230, in __call__
 self.load_middleware()
   File "/usr/local/lib/python2.6/dist-packages/django/core/handlers/
base.py", line 33, in load_middleware
 for middleware_path in settings.MIDDLEWARE_CLASSES:

functional.py", line 276, in __getattr__
 self._setup()
   File "/usr/local/lib/python2.6/dist-packages/django/conf/
__init__.py", line 40, in _setup
self._wrapped = Settings(settings_module)
   File "/usr/local/lib/python2.6/dist-packages/django/conf/
__init__.py", line 75, in __init__
 raise ImportError("Could not import settings '%s' (Is it on
sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE,
e))
 [error] [client 66.249.66.53] ImportError: Could not import settings
'iStore.settings' (Is it on sys.path? Does it have syntax errors?): No
module named iStore.settings

It seems that something wrong with
"os.environ['DJANGO_SETTINGS_MODULE']='www.iStore.settings'", but it
also does not work when i change it to
os.environ['DJANGO_SETTINGS_MODULE']='iStore.settings'
Anyone knows what is the problem?

Re: How to disable default authentication/messaging system?

[sanderkrause]

My INSTALLED_APPS looks like this currently.

Note that I did not have this same problem before, when I was using
Django 1.2. I recently upgraded to Django 1.3. Could this be part of
the problem?

The only other difference between now and then is that I used to have
the entries for contrib.auth and such in the INSTALLED_APPS, but
commented out. I don't see how this could affect my current situation
though, so my guess is, something changed in Django 1.3. Can anyone
confirm or deny this? I didn't see anything different in the
documentation.

INSTALLED_APPS = (
'django.contrib.sessions',
'form_utils',
'org',
'auth',
'entities',
)

If the user field on your Queue model is a ForeignKey to the User model, 
which it should be, this will happen automatically when you create the 
modelform.

Newbie question - modelform / dropdown list

[rune]

Hi all,

I just started with Django, done the tutorial, now I'd like to create
a page were users can put
requests in a queue. Lets say the fields to display are user, date,
filepath, date to load.
I can create this with a modelform, but I'd like the user field to be
a drop down list with values,
read from the data base. How would I do this?

regards,

Rune

make_messages verbosity

[tavis]

Just a small thing, I've noticed the default verbosity in the
make_messages function is the string '1'. The function never converts
this to an int, so if the function is called elsewhere without
specifying a verbosity level then when it checks to see if verbosity
is > 1 it always returns true.

Where should I report this?

Cheers,

Issues with post_save signals on test execution?

[rikuthero...@gmail.com]

Hi,

After migrate an application from Django 1.1 to Django 1.3 I noticed that
some unittest was failing. Debugging I get to the point that the post_save
functions didn't execute on test running. If I see the receivers on the test
execution:

ipdb> from django.db.models import signals
ipdb> signals.post_save.receivers
[]

But, seeing it on a ./manage.py shell:

In [4]: signals.post_save.receivers
Out[4]:
[((148050580, 135782264),
  ),
 ((148158980, 148372636),
  ),
 (((14908, 149046916), 148893804),
  BoundMethodWeakref( ._rename_resize_image )),
 (((150046508, 147356780), 150265060),
  BoundMethodWeakref( ._save )),
 (((150338604, 149046916), 150285820),


And a lot more... I check that the post_save signal is registering properly
on the test execution, but when you access to it, is empty.

Any ideas?

Thanks in advance

That's not what the docs say. They say you should create it on the Form. And 
where did you get the idea that the clean method takes any of those 
parameters?

The only reason syncdb would create the user tables is if contrib.auth is in 
INSTALLED_APPS. Can you post that?

Please tell how to implement a new project?

I m new to Django projects . if possible give me a graphical idea of
using Django from the base to the output.

My target is to make an inventory for a particular shop.

When the user enters the admin page for the first time it should be
asked to enter the credentials of the super user's user name passwd ,
store details, address, etc

And later the one should be having facility for user creation with
various permissions for transacting in the retail shop with their own
assigned id. the stock to maintained automatically.

the admin superuser login should be able to add catagory items vendors
price etc with other users who are given the permissions for such
with the facility  fo report and bill ...

How to disable default authentication/messaging system?

[sanderkrause]

Because I'm using my own authentication and authorization system, I
would like to completely disable these standard apps from Django.

I've tried removing the relevant lines from MIDDLEWARE_CLASSES and
INSTALLED_APPS, but when I use the syncdb command, the default tables
that come with the default authentication system are still being
created. Is there a way to prevent this from happening?

Is there maybe another setting that I'm overlooking? Other possible
variables that could cause these standard apps to be enabled despite
my efforts?

I also don't use the built-in admin system, so I don't think that
could be a problem.

Any hints?

use standard django views - but send the result to a wxPython file

I liked this explanation/convention

Subject: staticfile app question

Like many people, I'm switching over to use a static directory to
serve site media. Overall, it works extremely well, but I have a
question about one aspect of it.

I have a CSS file that includes urls. I was wondering about the
possibility of the staticfile app inserting the proper STATIC_URL as
it's being collected.

For example, things like:

#container-head {
background: transparent url('/static/img/bg/cap/head-inner-
bg.gif') 50% 0 no-repeat;
}

Would it be a bad idea to write like this:

#container-head {
background: transparent url('{{ STATIC_URL }}img/bg/cap/head-inner-
bg.gif') 50% 0 no-repeat;
}

the collectstatic command could insert the right url as it is being
copied?

Re: Trouble raising forms.ValidationError in save() override in admin.py

[Sithembewena Lloyd Dube]

Hi Shawn,

Thanks for the feedback. I read the docs and defined a clean_audio_file
method in my ModelAdmin class. I dropped the Podcast table, made the field
not mandatory in the model and did a syncdb (to test my clean method).

Still a podcast can be saved without the audio_file: the code in the clean
method does not appear to run. Please see the code below:

class PodcastAdmin(admin.ModelAdmin):
 list_display = ('title', 'audio_file', 'active', 'user')

 def clean_audio_file(self, request, obj, form, change):
  data = self.cleaned_data['audio_file']
  if not data or len(data) < 1 or data == "":
   raise forms.ValidationError("Provide a file!")
  return data

admin.site.register(Podcast, PodcastAdmin)

Am at a loss.

'NoneType' object has no attribute 'set_cookie'

[Santiago Caracol]

Hello,

I didn't use a certain Django project for a few weeks. Now I wanted to
continue developing the project and, as it usually happens with
software that has been left alone for a while, it didn't work
anymore. I am not aware of having changed anything. The system
administrator may, of course, have made some changes to the
system. When I try to add a new object, regardless of which type, in
the admin interface, I get the error messages given below. (I had to
shorten the error message for Google Groups to allow me to post it.)

Any ideas what I could do?

Django provides tools to get static content translated.
You are trying to do so on dynamic content which is really different.
You might want to look at http://djangopackages.com/grids/g/model-translation/ 
to get what you're looking for.

How many ? Three or two dozen ?

If you have no more than 2 or 3 languages to support, django-
transmetta has been an easy-working solution for us so far. Now I
don't think it would scale that well with too many languages -
depending on your model, it might add way too many fields to the
underlying table. In this case you may prefer another solution using
distinct rows for the translated versions (there are quite few django
apps doing this one way or another).

Because i18n is definitly not a simple problem, so there's no good one-
size-fits-all solution. The "right" strategy depends too much on your
specific application and needs.

Hi multilingual charfields?

[Mika Sjöman]

Hi

The content of my models have fields that need to be translated in the
django admin in several languages.

I found it to be a major hassle to get it working. Since django is having
internationalization built in, why does it not also allow you to easily mark
model fields for translation?

I think it should be built in to core since so many of us use multiple
languages in our webapps, so using it would be something like this:

1. import the multilang in models.py
2. flag specific fields for content translation
3. set the LANGUAGES in settings.py

What do you guys think?

getting _collect_sub_objects() error during delete if a foriegn key's foreign key is null

[dan levine]

Trying to delete objects from the django admin or app code, I'm
getting an error:

File "/home/styleseat/ssenv/lib/python2.6/site-packages/django/db/
models/base.py", line 595, in _collect_sub_objects
  sub_obj._collect_sub_objects(seen_objs, self, related.field.null)
AttributeError: ‘NoneType’ object has no attribute
‘_collect_sub_objects’

I'm using django 1.2.1 final

I think its easiest to decribe the models rather than post:

I'm trying to delete a Pro object.  Related models: we have
GalleryImage objects, GalleryImage extends Image, GalleryImage has a
FKs (null=True, blank=True) to Pro and to a Location object

If the Pro has any GallleryImage objects with a null Location the
error is thrown.  If I assign a Location object to the GalleryImage
then the Pro will delete, along with the GalleryImage objects and the
Location object.

Any thoughts?  I can put together a simple test case and post a bug
and/or work on a patch, but maybe its already been addressed in 1.3

Stack trace:

File "/home/styleseat/ssenv/lib/python2.6/site-packages/django/contrib/

RE: model manager and request

[Chris Matthews]

Hi,

1) My need for getting the current user is that I want the following columns on 
all tables: created, created_by, updated and updated_by.

So I defined this abstract class which I inherit from on all models:

class AbstractCommonAll(models.Model):
r''' All our tables will be defined with this class. We always want to know 
who
created it and when it was done. The same goes for who updated it and when 
it was done.

We could either have:
1 A char field for the user.
2 A foreign key to the user table.

If we take option 2 then we must define users for our batch jobs as well 
and all the queries
and updates will have to link to the user table. So let us just implement 
option 1 for now.
We can always change this at a later stage.
'''
created= models.DateTimeField(editable=False, help_text='When this row 
was created')
created_by = models.CharField(max_length=20, editable=False, help_text='Who 
created this row')
updated= models.DateTimeField(editable=False, help_text='When this row 
was updated')
updated_by = models.CharField(max_length=20, editable=False, help_text='Who 
updated this row')

class Meta:
abstract = True

def save(self):
if not self.id:
self.created = datetime.today()
self.created_by = 'user' # we should get this from 
request.User.username 
self.updated = datetime.today()
self.updated_by = 'user' # we should get this from request.User.username

super(AbstractCommonAll, self).save()

I am still going to implement getting the request.User.username as per ProJango 
by Marty Alchin Chapter 11 (page 253 onwards). I could do it in a view but then 
I still need it in the saves via admin. I should probably allocate a user for 
the batch programs and let them sign on so that they may have authenticated 
access and I suspect that I should make this batch user name available to 
AbstractCommonAll.save() because there will not be a request structure 
available.


2) For Audit/History records see the book ProJango by Marty Alchin Chapter 11 
(page 263 onwards) and 
http://qr7.com/2010/10/django-simple-history-ftw/ by Corey Bertram.
It handles the Historical records.

There is a possible error (depending upon your naming convention) when the 
indexes for the history tables are created:
sql_indexes_for_field() in 
/Python26/lib/site-packages/django/db/backends/creation.py creates the database 
index with name being model name + column name. This causes a problem for this 
implementation of history. 
The error is: Failed to install index for myapp.historical_Line model: relation 
" myapp_historical_line_type_id" already exists

It happens when the one modelname + foreignkey column name + '_id' is the same 
as the referenced modelname + '_id', as in the following example:

class Line_Type(models.Model):
name = models.CharField(max_length=50, unique=True)
description = models.CharField(max_length=100)

class Line(models.Model):
type= models.ForeignKey(Line_Type)


So the indexes created would be:
CREATE INDEX " myapp_historical_line*_type_id" ON " myapp_historical_line" 
("type_id");
CREATE INDEX " myapp_historical_line_type*_id" ON " 
myapp_historical_line_type" ("id");
 * is on the model/column name border.

To bypass this error I renamed my linked field (I thought that it would be more 
difficult to have sql_indexes_for_field changed [put a specified literal e.g. 
'_x_' between model & column names]) as follows:

class Line(models.Model):
line_type= models.ForeignKey(Line_Type)

(PS: I prefixed 'zz' to the history table names so that pgAdmin lists them at 
the end of, or after, the 'real' tables).

Regards
Chris

yeah, shawn said the exact dilemma I am having.  I am working with a
