Show HTML in Labels for Model Choice Fields

[Adi]

Hi I have a situation like this

class AppearanceThemesForm(forms.Form):
page_theme =
forms.ModelChoiceField(widget=forms.RadioSelect(attrs={'title':'Select
the appropriate theme for your pages.'}),
 
queryset=Theme.objects.filter(section="1"),
 
initial=Theme.objects.get(section="1",representation="").pk,
label="Page Theme")

And my Theme model is like this:

class Theme(models.Model):
name = models.CharField(max_length=32)
image = models.ImageField(upload_to="images/themes", null=True)

def __unicode__(self):
return "%s" % (self.name)


When I render AppearanceThemesForm in my template, i would like to be
able to show a link next to the label. If a user clicks the link, the
webpage displays the image associated with Theme.

I tried putting in a custom field that extends the ModelChoiceField,
and in the label_from_instance method, tried to output the HTML, but
that gets escaped.

What is the proper way to achieve what i am trying to do?

Alternatively, how do i get access the underlying model object behind
the modelchoice field in my templates?

Sorry for the repeats!  I was already a member of the

me bounce messages even after I joined from this address
and resent -- then all 3 copies came at once ... oops.  :(

Django not seeing AuthenticationMiddleware for some reason ...

[Stephen Waterbury]

I am baffled, and it's probably something simple I'm missing ...
I just need to send a message for help and then I'll see it ...
(maybe ... ;)

My set up:
* apache2 on Ubuntu 10.04
* mod_wsgi 3.3, compiled with python 2.6.5 (the system python)
  (but Ubuntu's mod_wsgi package was apparently not the problem)
* django installed in a virtualenv with python 2.6.5 also
* 2 django apps, one running on ':80' virtual host and one on
  ':8000' virtual host, each with a separate wsgi script (of course)
* apache server config (apache.conf) has WSGIPythonHome directive:
  'WSGIPythonHome [path to virtualenv directory]'
* virtualenv directory has python interpreter in its bin dir and
  python packages installed in its lib dir, including all django
  libs
* I have verified that AuthenticationMiddleware can be imported
  successfully from the command line within the virtualenv using
  the virtualenv's python intepreter
* both django apps live within the virtualenv directory,
  each in its own "project" directory there
* both apps are configured in apache with WSGIDaemonProcess directive

The error I continue to get is:

"ImproperlyConfigured at /

"The Django remote user auth middleware requires the
authentication middleware to be installed.  Edit your
MIDDLEWARE_CLASSES setting to insert
'django.contrib.auth.middleware.AuthenticationMiddleware' before
the RemoteUserMiddleware class."

The relevant sections of the settings.py files for the apps are:
--
MIDDLEWARE_CLASSES = (
  'django.middleware.common.CommonMiddleware',
  'django.contrib.sessions.middleware.SessionMiddleware',
  'django.contrib.auth.middleware.AuthenticationMiddleware',
  'django.contrib.auth.middleware.RemoteUserMiddleware',
)

AUTHENTICATION_BACKENDS = (
  'django.contrib.auth.backends.RemoteUserBackend',
  )
---

Ultimately I'll be using Active Directory (Kerberos) auth, but for
purposes of testing the REMOTE_USER stuff I've configured Basic
Authentication, and it is working (I authenticate successfully
before seeing that error message).

One thing that puzzles me is that in spite of a WSGIPythonHome
directive that points to the virtualenv, the error message lists
the "Python Executable" as "/usr/bin/python".  The "Python Path"
shown in the error message seems correct: it includes the
virtualenv's site-packages directory, which is where django is
installed (there is no system-level django installed, Ubuntu's or
otherwise), and as I say I tested that the middleware classes
that the error message complains about can be imported using the
virtualenv's python interpreter on the command line.

Any suggestions welcome!  (I can send the whole error page if it
would help, but I'll need to launder it a little.)

TIA!

Re: Caught NoReverseMatch while rendering:Reverse for 'index' with arguments '()' and keyword arguments '{}' not found.

[Bartolomé Sánchez]

Message error tells that you are trying to reach "index" url, which doesn't
exists. Maybe you are calling "index" url instead of "login".

Any idea what this means?

The URL entry is as per the django tutorial as:

(r'^login/$', 'django.contrib.auth.views.login', {'template_name':
'registration/login.html'}),

And in my settings.py file I specify
LOGIN_URL = 'login/'

Re: ModelForm validation in 1.2.3

[Burhan]

The question is how do I get the modelform to only check for form
validity, and not model validity (like it did before). I don't see
what your link has to do with that.

ModelForm and checkbox from choices

[robos85]

In my model i have that part:
... 

STATUSES_CHOICES = (
(0, _(u'one')),
(1, _(u'two')),
(2, _(u'three'))
)
...
status = models.SmallIntegerField(default=0, choices=STATUSES_CHOICES, 
null=True, blank=True)




then in my form based on that model I wanto to make that field as checkbox 
list. I know that I can make it as:
class Meta:
widgets = {'categories' : forms.CheckboxSelectMultiple, }

but, I want to change that field's label. How can I do that to server that 
list with changed label?

Re: Attempting to save instance with null ID?

[W. Craig Trader]

Jonathan ...

The problem is in the difference in SQLite and Oracle.  Unlike MySQL,
PostgresQL, and SQLIte, Oracle doesn't have auto-generated primary keys.  To
make up for that, Django on Oracle uses a trigger for each Django-managed
table that recognizes a NULL primary key on insert, and generates a key by
using a dedicated sequence for that table.  Usually if you're creating the
tables from scratch, the Django management tools (syncdb, sqlall, etc) will
create the sequence and trigger for you.  Without knowing more about how
your populated your schema, it's hard to say what went wrong, but if you run
'python manage.py sqlall invdb' it should print out the DDL to create the
trigger and sequence, and you can manually add them.

Re: User authentication in Django

According to the docs you just need to add

I think that your overall goal is quite admirable, but this may be an 
optimization too far.  One way to think of the way Django organizes its code is 
that a project is the platform on which applications are deployed.  The role of 
settings.py (and the top-level urls.py) is to configure the applications for a 
particular deployment, so things like STATIC_URL that are specific to a 
particular deployment of the app should not be in the app itself.

Thus, the top-level settings.py should include stuff that is:

1. General across all applications, or,
2. Used to configure a particular application for a particular deployment.

All that being said, it's no big deal to emulate the urls.py include facility 
in settings.py; just include your app-specific settings.  You can also have a 
'settings.py' (or whatever) file within the application that only that app 
imports.

Re: User authentication in Django

[aaron]

Okay, that problem is fixed. I just added the /accounts/login to the
url file.

New problem:

 my login page is giving me: CSRF verification failed. Request aborted

This is the html from login.html

{% block content %}

  {% if form.errors %}
Sorry, that's not a valid username or password
  {% endif %}

  
{% csrf_token %}
User name:

Password:




  

{% endblock %}

Any ideas?

Re: User authentication in Django

[aaron]

okay, so I added a url directing accounts/login requests to a view
which in turn directs it to the login.html template suggested at

http://docs.djangoproject.com/en/dev/topics/auth/

Which is:

{% extends "base.html" %}
{% load url from future %}

{% block content %}

{% if form.errors %}
Your username and password didn't match. Please try again.
{% endif %}


{% csrf_token %}


{{ form.username.label_tag }}
{{ form.username }}


{{ form.password.label_tag }}
{{ form.password }}



I've taken out the "base.html" stuff. When I now submit a user and
login (even though I've not yet created a user) I expect to see {% if
form.errors %}
Your username and password didn't match. Please try again.
{% endif %}

However instead I get an error: CSRF verification failed. Request
aborted.

Any ideas?

De-coupling settings.py from project

[eblume]

I'm new to Django and trying to create an office intranet web service.
Because I value pragmatic programming, I want to take the time to 'do
it right' and so I'm spending as much time as possible de-coupling the
'django application' from the 'django project' (or 'django site' -
these seem to be synonyms.)

To that end, I've managed to de-couple the urls.py file by using the
url importing system, and the templates by using a template loader.
However, a few settings seem to be impossible to de-couple from the
project to the application.

In particular, I'm having trouble specifying the static content URL
and the fixtures directories at a per-application level rather than in
the project settings.py file.

Is there a way to specify settings like STATIC_URL or FIXTURES_DIRS
per-application rather than per-site? Even better - is there a
mechanism to use a settings.py file in the application rather than in
the site?

Thanks,
eblume

User authentication in Django

[aaron]

Hi guys,

I'm attempting to follow the very simple setup for user authentication
in Django as detailed in the documentation here:

http://docs.djangoproject.com/en/dev/topics/auth/

I've got a database synced, the apps installed as detailed, but when I
attempt to access a password protected url it gives me the following
404 message:

Using the URLconf defined in logintest.urls, Django tried these URL
patterns, in this order:
^logintest/
^admin/doc/
^admin/
^secret/
The current URL, accounts/login/, didn't match any of these.

Secret is the app that simply renders a page that says 'secret'. It
works fine when the @login decorator is commented out.

Any ideas?

ModelForm validation in 1.2.3

[Burhan]

Hello:

  In 1.2 ModelForm validation was changed so that not only does it
check the form validation, but it does validation of the model as
well.

  I have a model that has custom validation for one of its fields,
which should be unique in the table. Now I have a front end form,
created by ModelForm for this model.

  I want do to the following:

  1. Check if the fields are correctly filled in, as per the custom
validator written for this model.
  2. If an entry already exists for using the 'unique' field, return
that object.
  3. If and entry doesn't exist, create a new object.

  In the old django, before this change, I could easily do it:

  if request.method = 'POST':
 form = CustomerForm(request.POST)
 if form.is_clean():
try:
customer =
Customer.objects.get(email=form.cleaned_data['email'])
except Customer.DoesNotExist:
customer = form.save()

 In 1.2.3, this logic always fails because "is_clean()" fails if an
existing customer enter's their email address. How can I do the same
using django 1.2.3?

Thanks.

Attempting to save instance with null ID?

Re: django using wrong python???

I work with CentOS too but installing different python versions in
parallel seemed like a lot of unnecessary work to maintain. So I
developed python-schizoid [0], a script that installs a virtual
environment with python 2.7, django trunk and many other useful
software.

It tries to install as much software inside the virtual environment as
possible to avoid depending on the (old) software installed on the
system. The only thing it does not install is the database engine.

Working like this makes packaging and deploying *a lot* easier because
your whole project and its dependencies (and even the python binaries)
are inside one directory. You also have the script bin/activate that
sets some useful environment variables that help working inside the
environment.

I know this doesn't actually answers your question but I thought you
may find it useful.

Re: ModelForm validation

[derek]

Alex

And I seem to have been equally unclear :}

I agree that cleaned_data is only available after is_valid() - the
point being that your form *will* be valid if you have set the value
for that field in a hidden input.  I do not see that this can be a
"security risk" - the default that you are setting beforehand is a
dummy (meaningless) value which, in any case, you are going to be
overriding.  How is this done?  Consider this example from the Django
Book (http://www.djangobook.com/en/1.0/chapter07/):

def contact(request):
if request.method == 'POST':
form = ContactForm(request.POST)
if form.is_valid():
topic = form.clean_data['topic']

Now if you wanted to overide the topic, you could instead have:
topic = 'my custom text'


Hope this is clearer!

ouch, I misunderstood your question. if you're using mysql as a db backend
for you django project, you can use pam-mysql
http://pam-mysql.sourceforge.net/ for the authentication on your servers.

django using wrong python???

[ozgur yilmaz]

Hi,

I'm on centos and have two pythons 2.5 and 2.6.

I tried in models.py:

from fractions import Fraction

and got the error: No module named fractions

But when i use shell and type "from fractions import Fraction" it's OK, it
uses python2.6 installation.

How can i modify django installation to use python2.6???

I already defined alias in bash_profile for python2.6, but it seems it
doesnt work for django.

Thanks,

I worked around the same problem (in 1.2, at least) with just an empty
models.py file—I didn’t even need the “pass”.

Re: django and eclipse

[CrabbyPete]

You have to set up the run environment. Make sure on run manage.py and
the parameters are runserver x.x.x.x:000 where x.x.x.x is the server
and :000 is the port you want to run from.  After that it should not
ask anything and run off your settings.

What i found disappointing is sending a NSFW image to a django list
without a note.

You want pam authentication. Look for django and pam.

OpenID Provider

[antoniofcano]

Hello,

I'm trying to setting up an OpenID provider for an application that I
wrote using Django. For this task I use the django_openid_provider
(http://www.romke.net/django/openid_provider/) app.

After installing, syncdb of the ddbb, associate an user with his
openid... the truth moment comes and it fails :(

I'm becoming crazy trying to debug the flow but without results. For
the consumer test I'm trying to publish a comment in blogspot. The log
of my runserver is this it:

Re: django and eclipse

[Rajendra Waghmare]

To run Django server on specific  IP and port you can use following
command:

python manage.py runserver :

e.g. python manage.py runserver 11.12.13.145:5678

If you do not specify IP and the port it starts on
localhost(127.0.0.1) and port 8000.

If you are using command prompt and do not want to use it, you can use
eclipse for the same, following link is useful for this:

Getting model instances from cursor fetches

[Viktor Kojouharov]

Hello,

I have a stored procedure which creates a cursor for a query, and also 
returns the total count for the (unlimited) query. The query itself can be 
mapped to my model if ran through the raw method of the manager. However, 
I'm interested in using the procedure, rather than 2 separate queries for 
the count and the instances.

The documentation indicates that I should use the connection.cursor method 
for invoking custom sql. My initial plan is to first execute the procedure, 
which would return the count and open the query cursor, and then execute a 
'fetch all' for that cursor (I doubt 'fetch next' would be better, since the 
result is stuffed into the django cursor anyway, but I could be wrong here). 
But after I fetch from the query cursor, how do I initialize my model 
objects with the data from that cursor?
