Loading initial data with Django 1.7 and data migrations

Question

I recently switched from Django 1.6 to 1.7, and I began using migrations (I never used South).

Before 1.7, I used to load initial data with a fixture/initial_d

Answer 1

In order to give your database some initial data, write a data migration. In the data migration, use the RunPython function to load your data.

Don't write any loaddata command as this way is deprecated.

Your data migrations will be run only once. The migrations are an ordered sequence of migrations. When the 003_xxxx.py migrations is run, django migrations writes in the database that this app is migrated until this one (003), and will run the following migrations only.
