reverse() function doesn't seem to take account of the includer urlconf

[Seemant Kulleen]

I have a urlconf being included from the top-level urlconf. the one being included is named, and I'm trying to get the reverse() function to work with the named one. It fails with the posted exception. I think this is wrong behaviour. Forgive my unorthodox use if this is the correct behaviour.

urls.py:
    (r'^blog/', include('kulleen.blog.urls.blogs')),
    (r'^(?P<member>[\w]+)/blog/', include('kulleen.blog.urls.blogs')),

blog/urls/blogs.py:
    url(
        r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/(?P<day>\w{1,2})/(?P<slug>[-\w]+)/$',
        'object_detail',
        dict(
            blog_dict,
            slug_field='slug',
            template_object_name = 'entry',
        ),
        name='entry_view',
    ),


exception:
In [1]: from blog.models import Entry

In [2]: e = Entry.objects.all()[65]

In [3]: e.get_absolute_url()

Try as I might, I cannot reproduce this problem. If you could construct a very small, self-contained example that reliably demonstrates the problem, that might make things easier to debug. I can't see how this could be happening and all the tests I create to replicate it, including making a small project with a similar structure to yours, pass.

[Flavio Curella]

this is my test case with django r9699

blog/models.py:

class Post(models.Model):
    """Post model."""
    title           = models.CharField(_('title'), max_length=200)
    slug            = models.SlugField(_('slug'), unique_for_date='publish')
    publish         = models.DateTimeField(_('publish'))

    @permalink
    def get_absolute_url(self):
        return ('blog_detail', None, {
            'year': self.publish.year,
            'month': self.publish.strftime('%b').lower(),
            'day': self.publish.day,
            'slug': self.slug
        })

urls.py:

from django.conf.urls.defaults import *

urlpatterns = patterns('',
    (r'^blog/(.*)', include('basic.blog.urls')),
)

blog/urls.py:

from django.conf.urls.defaults import *
from blog import views as blog_views

urlpatterns = patterns('',
    url(r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{1,2})/(?P<slug>[-\w]+)/$',
        view=blog_views.post_detail,
        name='blog_detail'),
)

sorry, I just found the error was mine. I apologize for the noise.

[Karen Tracey]

Replying to kratorius:
What's the reason for closing this as invalid? The person (gogna) who said "sorry, I just found the error was mine. I apologize for the noise" is not the same as person who originally opened the ticket (seemant). I do wish gonga had said what, exactly, the error was, perhaps it is the same problem as the original poster, but I'm not sure that's 100% obvious from what we have here.

[Ivan Giuliani]

Replying to kmtracey: woops, sorry for closing this, I just made confusion with names.

[Seemant Kulleen]

For some reason, I don't get emailed on updates, so I didn't see the comments till just now. I'm so sorry for the latency. I will put my examples up here in just a few minutes

[Malcolm Tredinnick]

The error in gogna's example in comment:3 is in the urls.py file. That pattern is capturing everything after the string "/blog/" (the (.*) part) and leaving nothing for the patterns in blog/urls.py to match against. Changing the urls.py pattern line to

#python
(r'^blog/', include('blog.urls')),

fixes that problem.

So I'm still in the position of not being able to repeat this problem. Unless somebody comes up with a reliable failing case in the next few weeks, I think we're going to have to close this as invalid. I've created a lot of different variations on the original problem report and none of them have failed.
