Re: Data migration fails because contenttypes not yet ready

Hey Torsten,

Are you talking about Django 1.7 migrations or South? In the former case
you need to make sure that your datamigration depends on the
contenttypes application.

If you use South: yes, calling update_all_contenttypes seems to be a
valid solution.

Best,

Markus
