Getting Django admin url for an object

Before Django 1.0 there was an easy way to get the admin url of an object, and I had written a small filter that I'd use like this: <a href="{{ object|admin_url }}" .... > ... </a>

Basically I was using the url reverse function with the view name being 'django.contrib.admin.views.main.change_stage'

reverse( 'django.contrib.admin.views.main.change_stage', args=[app_label, model_name, object_id] )

to get the url.

As you might have guessed, I'm trying to update to the latest version of Django, and this is one of the obstacles I came across, that method for getting the admin url doesn't work anymore.

How can I do this in django 1.0? (or 1.1 for that matter, as I'm trying to update to the latest version in the svn).

I had a similar issue where I would try to call reverse('admin_index') and was constantly getting django.core.urlresolvers.NoReverseMatch errors.

Turns out I had the old format admin urls in my urls.py file.

I had this in my urlpatterns:

(r'^admin/(.*)', admin.site.root),

which gets the admin screens working but is the deprecated way of doing it. I needed to change it to this:

(r'^admin/', include(admin.site.urls) ),

Once I did that, all the goodness that was promised in the Reversing Admin URLs docs started working.

You can use the URL resolver directly in a template, there's no need to write your own filter. Eg

{% url 'admin:index' %}

{% url 'admin:polls_choice_add' %}

{% url 'admin:polls_choice_change' choice.id %}

{% url 'admin:polls_choice_changelist' %}

from django.core.urlresolvers import reverse
def url_to_edit_object(object):
  url = reverse('admin:%s_%s_change' % (object._meta.app_label,  object._meta.model_name),  args=[object.id] )
  return u'<a href="%s">Edit %s</a>' % (url,  object.__unicode__())

这与hansen_j的解决方案类似，只不过它使用了url命名空间admin：作为管理员的默认应用程序名称空间。
