Migrations and multiple databases

[odd hogstad]

I have two databases in my project, db1, which changes quite frequently, and db2, which seldom changes. The app was original written in django 1.3, but we've upgraded since then, and now uses 1.8. Now I need to make a change on db2 for the first time since the upgrade from 1.3. I make my changes in the model, but when I do python manage.py migrate model_of_db2 db2, the changes seems to be applyed, but I get an error:

"Error creating new content types. Please make sure contenttypes "

RuntimeError: Error creating new content types. Please make sure contenttypes is migrated before trying to migrate apps individually.

I tried adding a router, but same issue. What am I doing wrong? Do I need contenttypes also in db2?

Thanks!

hi Hogstad,

Before doing app migrate please python manage.py migrate auth ==>I hope this will solve the issue

db1 holds the auth stuff already. Do I need to also have it in db2 for the migrations to work?
