Found! This helper method exists already:
`django.core.management.sql.emit_post_migrate_signal`
{{{
from django.core.management.sql import emit_post_migrate_signal
def create_group(apps, schema_editor):
db_alias = schema_editor.connection.alias
try:
emit_post_migrate_signal(2, False, 'default', db_alias)
except TypeError: # Django < 1.8
emit_post_migrate_signal([], 2, False, 'default', db_alias)
Group = apps.get_model('auth', 'Group')
Permission = apps.get_model('auth', 'Permission')
(...)
}}}
I suggest this behavior and "how to deal with" to be documented on the
Permissions page.
Is this acceptable instead of a ''wontfix'' ?
