Comment (by MarkusH):
Hi Shai,
the managers will be serialized in the same way as e.g. functions for
field arguments are serialized: imported and referenced. A migration for a
custom user model will thus look like
{{{#!python
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models, migrations
import myapp.models
class Migration(migrations.Migration):
operations = [
migrations.CreateModel(
name='MyUser',
fields=[
('id', models.AutoField(verbose_name='ID',
serialize=False, auto_created=True, primary_key=True)),
('password', models.CharField(max_length=128,
verbose_name='password')),
('email', models.EmailField(max_length=255,
verbose_name='email address', blank=True, unique=True)),
],
options={
'verbose_name': 'user',
'verbose_name_plural': 'users',
},
managers=[
('objects', myapp.models.MyUserManager()),
],
),
]
}}}
The `managers` argument keeps track of all managers of a model unless only
the default manager (`objects = models.Manager()`) is available. The
argument will be empty / not given in those situations.
A current work-in-progress implementation is available in my
[https://github.com/MarkusH/django/compare/migration-managers migration-
managers] branch.
