Adding django admin permissions in a migration: Permission matching query does not exist

In django 1.10 the following code could be used:

from django.contrib.auth.management import create_permissionsdef migrate_permissions(apps, schema_editor):    for app_config in apps.get_app_configs():        app_config.models_module = True        create_permissions(app_config, apps=apps, verbosity=0)        app_config.models_module = None

Django <= 1.9

see another answer for Django 1.10+

It's enough to call create_permissions:

from django.contrib.auth.management import create_permissionsapps.models_module = Truecreate_permissions(apps, verbosity=0)apps.models_module = None

The whole migration being something like this

# coding:utf-8from django.db import migrationsfrom django.contrib.auth.models import Permission, Groupfrom django.contrib.auth.management import create_permissionsfrom django.contrib.contenttypes.models import ContentTypefrom django.conf import settingsMODERATORS_PERMISSIONS = ['change_modelname', ]def add_permissions(apps, schema_editor):    apps.models_module = True    create_permissions(apps, verbosity=0)    apps.models_module = None    moderators_group = Group.objects.get_or_create(        name=settings.MODERATORS_GROUP)[0]    for codename in MODERATORS_PERMISSIONS:        permission = Permission.objects.get(codename=codename)        moderators_group.permissions.add(permission)class Migration(migrations.Migration):    dependencies = [        ('contenttypes', '0002_remove_content_type_name'),        ('thisappname', '0001_initial'),    ]    operations = [        migrations.RunPython(add_permissions),    ]

And if you want something that will work on any version (or that will keep working when you upgrade):

from django.contrib.auth.management import create_permissionsversion = django.VERSIONif version[0] >= 1 and django.VERSION[1] > 9:    for app_config in apps.get_app_configs():        app_config.models_module = True        create_permissions(app_config, apps=apps, verbosity=0)        app_config.models_module = Noneelse:    apps.models_module = True    create_permissions(apps, verbosity=0)    apps.models_module = None
