-migrations-custom-user-model-and-postgres-mysql
Basically - developing with SQLite3 worked perfectly fine with my custom
user model {{{class Client(AbstractBaseUser, PermissionsMixin}}}
When time came to get to production and use postgres or mysql, things
started failing. The root of it is that the migrations aren't being run in
the right order, and there are foreign key relations that aren't
maintained.
What's odd is that running {{{./manage.py migrate}}} twice in a row seems
to work. Unfortunately this doesn't seem to help with tests. In no
particular order, I would love some advice on:
1) How to unblock myself such that stuff 'just works' (my nuclear option
is removing the custom user model and custom user manager, and migrating
the old data over, which will take some time)
2) Understanding why everything seemed to work fine with SQLite, and why
it fails with postgres/mysql
The solution of running `./manage.py makemigrations offerdrive'` listed
here doesn't help unfortunately...:
