Comment (by Jaap Roes):
That seems similar to the solution I've been using for a while:
{{{
class NoMigrations:
"""Disable migrations for all apps"""
def __getitem__(self, item):
return None
def __contains__(self, item):
return True
MIGRATION_MODULES = NoMigrations()
}}}
(Which I also suggested it as a temporary solution in the original ticket
https://code.djangoproject.com/ticket/25388#comment:20)
I hadn't actually tried this `MIGRATION_MODULES` override on this project
before. I just did a test run with the override and or some reason I had
to add a `fixtures = ['myapp/initial_data.json']` line to some of the
`TestCase` classes that worked fine without it before. It seems that these
test cases really needed this fixture, but for some reason worked fine
when migrations are enabled. Is (test) fixture loading somehow tied to
migrations?
Anyway, the tests work fine (the same 3 failures) with the
`MIGRATION_MODULES` override, so it seems like it would be a reasonable
alternative solution.
