How do I execute custom sql in a test right after the database is created?

[John Rambo]

First of all I know that is bound to break a lot of other things.

I changed the core so references to tables are PostgreSQL fully qualified 
table name (e.g. "family"."person" instead of family_person). So far it had 
been doing what I want except I can't run tests because the schemas are not 
created in a new database.

How would I run arbitrary SQL right after the test database is created so I 
can create the schemas?

Thanks,

JR

distinct().filter() applies filter before distinct

[John Rambo]

 

If we chain a call to filter() after a call to distinct(), the filter is 
applied to the query before the distinct. How do I filter the results of a 
query *after* applying distinct?

Example.objects.order_by('a','b').distinct('a').filter(b='something)

The where clause in the SQL resulting from filter() means the filter is 
applied to the query before the distinct. I want to filter the queryset 
resulting from the distinct.

This is probably pretty easy, but I just can't quite figure it out and I 
can't find anything on it.

Another way to ask the question is how do I return a distinct QuerySet and 
then filter it?

Re: distinct().filter() applies filter before distinct

[John Rambo]

This better illustrates what I mean:

Example.objects.order_by('a','foreignkey__b').distinct('a').filter(foreignkey__b='something')

Can't run tests when admin is part of INSTALLED_APPS?

[John Rambo]

If I try to run test suites in 1.7 with admin in INSTALLED_APPS, I get 
this...

  File "/django/core/management/commands/migrate.py", line 195, in 
model_installed
(opts.auto_created and converter(opts.auto_created._meta.db_table) in 
tables))
AttributeError: 'bool' object has no attribute '_meta'

If I comment out the django.contrib.admin, tests work fine.

I do not know how to dig further from here. Is anyone able to point me in 
the right direction?
