Re: merge 2 views?

The one downside to this solution is that these variables will fetched
for every request, even if navigation.html was not included in the
output template.

An alternative solution would be to create a template tag that fetches
these variables, and only load and use this template tag in
navigation.html. That way those variables are only fetched if
navigation.html is included.

It's a little bit more complicated in code though (made a lot easier
in Django 1.3 with simple_tag), and might not be worthwhile if you
aren't doing complicated computations.

Can't you implement a static files finder, in the similar way to
template loaders to achieve the same effect?

As Christophe explained, it is possible, but I also agree with
Christophe - you're going to the extreme for very unlikely use cases.
Also keep in mind that every time Django handles a request, it will
import the settings for *every* app, instead of just the app you think
will be used to handle the request. Settings could then clash, making
debugging a pain.

The four part tutorials! I used to get frustrated that they just ended
too. I did them numerous times. In the end, it was starting my own
project and then hanging out in the boot camp known as [mailing
list|irc|docs]. That's it. I'm sure I'm not alone here in not knowing
Django inside out. Build it, and as you need something, look read and
ask. I don't think there's a short cut. The intro tutorials are
excellent for a broad overview and getting started on your own project
though.

cannot login to admin site with superuser

Hi,

It seems that for some reason I can't login to admin site or my
webpage using the admin user. I even created a new superuser with
manage.py createsuperuser using plain numbers as my password ('123').
So it is not a password issue.

However when I try to django-admin validate I get an import error like
this:

Error: Could not import settings 'myproject.settings' (Is it on
sys.path? Does it have syntax errors?): No module named
myproject.settings

c:\workspace\myproject is on my sys.path. I also did a
sys.path.append() c:\workspace but I still get the same error.

I also tried this:

http://coderseye.com/2007/howto-reset-the-admin-password-in-django.html

but still I can't login.

Admin user cannot login to the myproject web page. Other users can. I
use a postgresql database. I used to have a mysql db but I switched to
postgresql. Don't know if that matters.

I also use django 1.2.1 on windows 7.

Any help would be appreciated. I have tried hard and now I am
completely lost.

ANN: The django CMS 2.1 Release Candidate 2 has been released!

The second Release Candidate for the Django-CMS 2.1 was just released
and is
ready for testing. Please keep in mind that this is a release candidate,
and not
a final release yet!

Download: http://pypi.python.org/pypi/django-cms/2.1.0.rc2
Documentation: http://django-cms.rtfd.org
Source: https://github.com/divio/django-cms/tree/2.1.0.rc2

Please report any issues you find with this release to our issue tracker at
https://github.com/divio/django-cms/issues, thank you.

This second Release Candidate fixes a few bugs found in 2.1 RC1 as well
as a
compatibility problem with Django 1.2.4 which was released shortly after
RC1.

The bugs fixed in RC2 are:

- #621: Page changelist in admin is incompatible with Django 1.2.4 when
using multiple sites
- #624: Saving pages with a language not available to the site currently
being browsed, but available to the target site of the page
- #631: MultilingualURLMiddleware does not work with single-quoted urls
in templates
- #630: Pages cannot be added if CMS_MODERATOR is False

There are currently no known issues with RC2.

So what's new in 2.1?

* Frontend Editing!
You can edit your contents directly on the site, as an alternative to
the more
abstract admin panel.

* Better integration of 3rd party applications!
It is now easier then ever to integrate any 3rd party Django
applications into
your CMS or make your Django application CMS-Ready.

* "Placeholders"
It is now possible to use the Django-CMS Plugin based content
architecture in
any Django model using the new Placeholder Fields! This even comes
with full
blown frontend editing.

* Menu Refactor
The menu code has been strongly refactored since 2.0 and it is now
easier to
extend and alter the menus.

* Better Docs, Better Tests, Better Code
Our documentation is now hosted on the amazaing readthedocs.org and was
improved vastly and is still being improved until 2.1 final. On top
of that
our testing infrastructure, our test suite and our test coverage has
improved
significantly as well. And in the process of fixing a lot of bugs, we
have
also improved the readability and maintainability of the Django-CMS
codebase
to make it easier for new developers to get around.

* And lots more!

In the name of the django CMS Core Developers team I wish you all a
happy new year and enjoy our RC2!

DJANGO BOOTCAMP

Hi all,

I recently started working on a project which is based on django. I've had reasons to work through the documentation several times to get things done.
However, each time I check the documentation, I find out there is more to learn hence, my thought.

Is there any or can there be a django clinic for beginners or a bootcamp for beginners where people can go through the process of learning django.

With the little I have seen of the so many that is possible, can there not be such arrangement for beginners like me to tap into. Reading the documentation alone may not help as having a guide.

The value of a Datefield is a Python datetime.date object. To see the

Show HTML in Labels for Model Choice Fields

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?

Django not seeing AuthenticationMiddleware for some reason ...

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!
Steve

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

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

2010/12/30 aaron <aaron.jerling@gmail.com>

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: Attempting to save instance with null ID?

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
{% csrf_token %}

to each form.

sorry for the noise.

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!

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

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 %}
<p class="error">Sorry, that's not a valid username or password</
p>
{% endif %}

<form action="" method="post">
{% csrf_token %}
<label for="username">User name:</label>
<input type="text" name="username" value="" id="username">
<label for="password">Password:</label>
<input type="password" name="password" value="" id="password">

{% endblock %}

Any ideas?

Re: User authentication in Django

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 %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}

<form method="post" action="{% url 'django.contrib.auth.views.login'
%}">
{% csrf_token %}
<table>
<tr>
<td>{{ form.username.label_tag }}</td>
<td>{{ form.username }}</td>
</tr>
<tr>
<td>{{ form.password.label_tag }}</td>
<td>{{ form.password }}</td>
</tr>
</table>

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 %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}

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

Any ideas?

De-coupling settings.py from project

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

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

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?

I'm migrating from SQLite to Oracle, and I'm getting an error thrown on the line disn_requisition.save() claiming that it has a null ID. I have not attempted to manually set or fiddle with id fields on any model, although I do read them.

Any insight on what I need to do to address this?

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.

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.

Re: django using wrong python???

you can try ln -s python2.6 to default python, and then modify the yum script to python2.4.

Why/how have you two versions of Python installed?

Where is Django installed?

django using wrong python???

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

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.

I'm migrating from SQLite to Oracle, and I'm getting an error thrown on the line disn_requisition.save() claiming that it has a null ID. I have not attempted to manually set or fiddle with id fields on any model, although I do read them.
