[patch] Make admin view methods wrappable by user views for non-staff

[garthk@…]

I'm trying to call admin views from my views to greatly simplify my code. My efforts are frustrated by this style of view definition in django.contrib.admin.views.main:

def useful_view_method(request): 
   # ...
useful_view_method = staff_member_required(usefulmethod)

Thanks to the wrapper, the method is useful only to the admin interface unless I make a copy of it. Such a copy is inefficient, error-prone, and requires checking each Django code update.

Making the unprotected view available as follows would let me wrap the view myself to whatever protection level I see fit:

def _useful_view_method(request):
    # ...
useful_view_method = staff_member_required(_useful_view_method)

On a similar line of thinking: change_list needlessly insists on change permission. I'd like it to list regardless, as even mortals should be able to view the table I've got in mind. I can have my change_stage equivalent check permissions and then pass on to either a read-only view method or the "official" change_stage, at least once I can reach around the staff_member_required wrapper.

[patch] permit wrapping of change_list et al

(In [4577]) Fixed #2104: allow somewhat nicer error messages in RequiredIfOtherFieldEquals validator. Thanks, Steven Armstrong

Darn it, that commit was supposed to close #2014, not #2104.

Reopening.

[garthk@…]

If you want to close #2014 with some code, though, feel free. :)

I think it would be nice to be able to re-use some of the admin functionality in other places. The new admin options stuff being talked about will allow you to run multiple admin interface instances and use different authorization checks, so maybe that will fix this ticket.

[garthk@…]

Control over the authorisation checks and URL would definitely help. Where is this "talked about"?

The admin views are going away, to be replaced with a much more customizable AdminSite class.
