This fixture returns a helper object to test Django data migrations.
|
||||
The fixture returns an object with two methods;
|
||||
- `before` to initialize db to the state before the migration under test
|
||||
- `after` to execute the migration and bring db to the state after the migration
|
||||
The methods return `old_apps` and `new_apps` respectively; these can
|
||||
be used to initiate the ORM models as in the migrations themselves.
|
||||
For example:
|
||||
def test_foo_set_to_bar(migration):
|
||||
old_apps = migration.before([('my_app', '0001_inital')])
|
||||
Foo = old_apps.get_model('my_app', 'foo')
|
||||
Foo.objects.create(bar=False)
|
||||
assert Foo.objects.count() == 1
|
||||
assert Foo.objects.filter(bar=False).count() == Foo.objects.count()
|
||||
# executing migration
|
||||
new_apps = migration.apply([('my_app', '0002_set_foo_bar')])
|
||||
Foo = new_apps.get_model('my_app', 'foo')
|
||||
|
||||
assert Foo.objects.filter(bar=False).count() == 0
|
||||
assert Foo.objects.filter(bar=True).count() == Foo.objects.count()
