    initial v1  
    11Well in some ways I think the patch creates some consistency given that there is already a hook for the "view on site" url in the admin. Grepping around, there could be some savings of lines get_*_url in the tests where basically the same hooks already exists.

    3 Example: http://dpaste.com/1JFCGQG
     3Example:
     4
     5{{{ #!python
     6# /parents/1/child_changelist
     7
     8class ParentAdminSite(admin.Site):
     9    def get_urls(self):
     10        return super(ParentAdminSite, self).get_urls() + [
     11            url(r'^(?P<parent_id>%s)/children/', include(ChildObjectAdmin(imodels.ChildObject, self).urls)))
     12        ]
     13
     14
     15class ChildObjectAdmin(admin.ModelAdmin):
     16    def changelist_view(self, request, parent_id=None):
     17        if parent_id:
     18            self.parent_id = parent_id
     19            self.parent = get_object_or_404(models.Parent, parent_id=parent_id)
     20        return super(ChildObjectAdmin, self).changelist_view(request)
     21
     22    def get_queryset(self, request):
     23        return super(ChildObjectAdmin, self).get_queryset(request).filter(parent=self.parent)
     24}}}

    526The current implementation presumes that a modeladmin is registered under a namespace with no other args or kwargs, but that may not be the case if someone has included additional url args in get_urls(). Almost everything about the admin works fine out of the box in this situation aside from the somewhat superficial problem of where the user is redirect post-save because, the urls that are being reversed deep in response_change (and subsequently response_post_save_change) are hard-coded.
