Processing of urlconf extra args, and removing args

[oyvind@…]

Allows for arguments to be pre-processed to allow urls to be more sensible, ie. comments below blog post.

Also allows arguments to be removed so arguments needed for preprocessing can be removed befor being passed to views.

Not sure if this is a good idea, but i just wanted to see if this is something django needs.

Example code:

form page.models import Page

class comments_urlprocessor:

def init(self, model, args=[]):

self.model, self.args = model, args

def call(self, *args, kwargs):

for key in kwargs.keys():

if key not in self.args:

del kwargskey

try:

commented_object = self.model.objects.get(kwargs)

except:

commented_object = False

return {'commented_object': commented_object}

info_dict = {

'queryset': Page.objects.all(),

}

commments_dict = {

'process_kwargs': comments_urlprocessor,
'remove_kwargs': ['pk','comments_urlprocessor'],

'comments_urlprocessor': comments_urlprocessor(Page, pk),
'commented_object_template': 'page.html'

}

urlpatterns = patterns(,

(r'^{(?P<object_id>\d+)/$', 'django.views.generic.list_detail.object_detail', dict(info_dict, object_id=1, template_name='page.html')),
(r'}(?P<pk>\d+)/comments/', include('advancedcomments.urls'), commments_dict ),

)

Ouch, needs some formatting

from django.conf.urls.defaults import *
from pages.models import Page

class comments_urlprocessor:

    def __init__(self, model, args=[]):
        self.model, self.args = model, args

    def __call__(self, *args, **kwargs):

        for key in kwargs.keys():
            if key not in self.args:
                del kwargs['key']

        try:
            commented_object = self.model.objects.get(**kwargs)
        except:
            commented_object = False

        return {'commented_object': commented_object}

info_dict = {
    'queryset': Page.objects.all(),
}

commments_dict = {

    'process_kwargs': ['comments_urlprocessor'],
    'remove_kwargs': ['pk','comments_urlprocessor'],

    'comments_urlprocessor': comments_urlprocessor(Page, ['pk']),
    'commented_object_template': 'page.html'
}

urlpatterns = patterns('',
    (r'^(?P<object_id>\d+)/$', 'django.views.generic.list_detail.object_detail', dict(info_dict, object_id=1, template_name='page.html')),
    (r'^(?P<pk>\d+)/comments/', include('advancedcomments.urls'), commments_dict ),
)

I really can't see the use case here.
