Another shot at this problem ..

settings_test_snippet.py

class DisableMigrations(object):

    def __contains__(self, item):
        return True

    def __getitem__(self, item):
        return "notmigrations"

MIGRATION_MODULES = DisableMigrations()

This worked for me, and it is more simple than other solutions I came accross.

Just so everyone can support the publicly release app by @henriquebastos that includes this snippet:

• https://github.com/henriquebastos/django-test-without-migrations

Should rename the app to "headache reliever". Thanks guys! 👍

Is there a way to use it with django-nose?

Could someone please explain exactly how you use this snippet when running your tests? Thank you.

@flaugher: create a settings_test.py next to your regular settings.py:

import * from settings
# snippet content goes here

Then run your tests with settings_test instead of regular settings:

manage.py test --settings mysite.settings_test [test spec]

This is a great tool, but I use the hstore field on some models and the recommend way to install the hstore extension is via a migration: https://docs.djangoproject.com/es/1.9/ref/contrib/postgres/fields/#hstorefield

Any idea how I can run only one migration or run some custom SQL to install the extension?

@jamescw,

Based on the same source as this app, I use something like this in my settings:

RUN_MODE = sys.argv[1] if len(sys.argv) > 1 else None

if RUN_MODE == 'test':
    class DisableMigrations(dict):
        except_apps = {'app_to_run_migrations_for'}
        def __contains__(self, item):
            return item not in self.except_apps
        def __getitem__(self, item):
            return super(DisableMigrations, self).__getitem__(item) if item in self.except_apps else None

    MIGRATION_MODULES = DisableMigrations()

Not sure if someone else has the issue, but when I tried this snipped on my project that contains Cartridge, during the table creation it complains that one of the ManyToMany table already exists... Does anyone else had an issue with that?

Thanks. Used this snippet with another scenario where there was need to re-create "unmanaged" database tables during tests:

So, how do you use this pattern when you want to test migrations as part of your test suite?

For those who use pytest-django, it already supports commands to define db behaviour on tests:

@cjw296

You can have a stage env with a different pytest.ini where you test migrations.

Looks like you need to alter this slightly on Django 1.11:

def __getitem__(self, item):
        return None
