Hi, I have problem migrating some 3rd party database with Django
migrations. I have used router for controlling which apps are allowed to
be migrated on this database. But I have problem with **HStoreExtension**
operation because these operations don't check if they are allowed. And
because I have limited rights and I am controlling only my schema on that
database I will get error while installing hstore.
Source of trouble:
https://github.com/django/django/blob/master/django/contrib/postgres/operations.py#L18
Work-around/proposal for CreateExtension class:
{{{
class RoutingHStoreExtension(HStoreExtension):
def database_forwards(self, app_label, schema_editor, from_state,
to_state):
if not router.allow_migrate(schema_editor.connection.alias,
app_label):
return
return super().database_forwards(app_label, schema_editor,
from_state, to_state)
}}}
