I have been trying to find the answer in the Django Auth docs, but can not seem to find what I am looking for.
The problem I am having is, when I define the code for ad
I was recommended this way to do it:
Create a fake migration in the appropriate module:
python manage.py makemigrations --empty yourappname
Open up the file that was created, which should look like this:
# -*- coding: utf-8 -*-
from django.db import models, migrations
class Migration(migrations.Migration):
dependencies = [
('yourappname', '0001_initial'),
]
operations = [
]
And add your code:
# -*- coding: utf-8 -*-
from django.db import models, migrations
def add_group_permissions():
#read_only
group, created = Group.objects.get_or_create(name='read_only')
if created:
group.permissions.add(can_read_campaign)
logger.info('read_only_user Group created')
#standard
group, created = Group.objects.get_or_create(name='standard_user')
if created:
group.permissions.add(can_edit_users)
logger.info('standard_user Group created')
#admin
group, created = Group.objects.get_or_create(name='admin_user')
if created:
group.permissions.add(can_edit_campaign, can_edit_users)
logger.info('admin_user Group created')
class Migration(migrations.Migration):
dependencies = [
('yourappname', '0001_initial'),
]
operations = [
migrations.RunPython(add_group_permissions),
]
Finally, run the migration:
python manage.py migrate
This is nice because you can deploy to Heroku or wherever and be sure it'll be applied, as it's just another migration.
Combining @Robert Grant and this I was able to do it like:
python manage.py makemigrations --empty yourappname
And then:
from django.contrib.auth.models import Group, Permission
from django.db import models, migrations
import logging
logger = logging.getLogger(__name__)
campaign_group_permissions = {
"Campaign Manager": [
"add_campaign",
"change_campaign",
"delete_campaign",
"view_campaign",
"add_campaignsms",
"add_sending",
"change_sending",
"view_sending"
]
}
def add_group_permissions():
# See https://code.djangoproject.com/ticket/23422
db_alias = schema_editor.connection.alias
try:
emit_post_migrate_signal(2, False, 'default')
except TypeError: # Django < 1.8
emit_post_migrate_signal([], 2, False, 'default', db_alias)
for group in campaign_group_permissions:
role, created = Group.objects.get_or_create(name=group)
logger.info(f'{group} Group created')
for perm in campaign_group_permissions[group]:
role.permissions.add(Permission.objects.get(codename=perm))
logger.info(f'Permitting {group} to {perm}')
role.save()
class Migration(migrations.Migration):
dependencies = [
('yourappname', '0001_initial'),
]
operations = [
migrations.RunPython(add_group_permissions),
]
Note: this works on Django 3.x, but I'm pretty sure it will work for Django 1.7 as well.
