Doing pre-migrate database requirements — at Version 3
Description (last modified by ) ¶
Some database backends has special requirements when the database gets migrated.
For example, when using django.contrib.gis.db.backends.spatialite as a backend, the database file should be initialized at first time with this command: "SELECT InitSpatialMetaData();"
Unless, it causes some error like https://code.djangoproject.com/ticket/20968.
I guess this would be appropriate: adding a before_migration() method to DatabaseWrapper, and letting database backends inherit it to do some jobs.
New workaround codes are added to django/contrib/gis/apps.py. (Thanks @aaugustin!)

Look at
django/contrib/postgres/apps.py
for how to implement this.
