Django Migrate Schema From Sqlite To Postgresql

I am developing a large django-based project. On my laptop I use SQLite3 as a database. I have created a lot of migrations for my models. Everything seems working. Then I want to u

Solution 1:

Django handles dependencies between models in migrations correctly. What it can't handle, and what it explicitly warns against in the docs, is unmigrated apps with dependencies on migrated apps:

Be aware, however, that unmigrated apps cannot depend on migrated apps, by the very nature of not having migrations. This means that it is not generally possible to have an unmigrated app have a ForeignKey or ManyToManyField to a migrated app; some cases may work, but it will eventually fail.

Warning

Even if things appear to work with unmigrated apps depending on migrated apps, Django may not generate all the necessary foreign key constraints!

In this specific case is seems that the registration app has a dependency on the user model. You need to upgrade this app to a version that has the necessary migration files to support Django 1.7+.
