Add tests for 'Allow DB-level ordering by non-fields in changelist view' admin functionality

Description

The attached patch lets you specify a field to sort a non-field
column in the admin list view. I created it for the django-multilingual
library, but there are more cases where this could prove useful.
See the example in docs/model-api.txt diff.

Seems useful.

Summary: [patch] Allow ordering by non-fields in admin list view → [patch] Allow DB-level ordering by non-fields in admin list view

Renamed the ticket to clarify it.

Triage Stage: Design decision needed → Ready for checkin

This seems reasonable. It's a little bit hard to understand until you read the docs, but the example gets the point across. The documentation paragraph probably needs a rewrite -- it feels a bit awkward at the moment. But I'm too tired to get it right now; we just need to remember to tweak that before checking in. Other than that, this looks fine.

(In [4596]) Fixed #3397: You can now order by non-DB fields in the admin by telling Django which field to actually order by. Thanks, marcink@…

This doesn't quite work correctly. It allows clicking on the column title to sort in ascending order but it doesn't display the triangle and a second click will sort ascending rather than descending.

The fix is for admin_list.py line 104 to also check if the admin_order_field equals cl.order_field.

Patch attached.

Unless I'm mistaken, in django/contrib/admin/views/main.py in section added in this patch, there(see my patch patch_allow_ordering_by_nonfields_fix.diff) should be AttributeError instead of IndexError (IndexError cannot raise there and IMO author meant there AttributeError)

comment:8 by marcin@…, 18 years ago

glin: you are right, it should be an AttributeError. I missed it because usually this code path is not executed at all, but it is a bug and should be fixed.

The file "patch_allow_ordering_by_nonfields_fix.diff" should be checked in following the last two comments (i.e. should be AttributeError not IndexError.

comment:10 by Gary Wilson, 17 years ago

(In [5799]) Refs #3397 -- Corrected the Exception that is caught when ordering by non-fields (added in [4596]), thanks glin@….

comment:11 by Gary Wilson, 17 years ago

Has patch: unset
Needs tests: set
Triage Stage: Ready for checkin → Accepted

Just because the other parts of the admin don't have tests doesn't mean that we should continue the trend.

Can someone verify if this broken on trunk? It sounds likely it will work just fine, but needs really needs a test case.

Replying to brosner:

Verified the function works correctly on trunk [8169]. I guess the ticket was just reopened because the function lacks a test.

In the intervening years since this was reopened, tests have been added for admin_order_field, see for example: ​http://code.djangoproject.com/browser/django/tags/releases/1.2.5/tests/regressiontests/admin_views/tests.py#L192

I think it's OK to close this one as fixed now.
