How to retrieve all permissions assigned to a group in Django

Question

I am working on a task to retrieve a set of permissions assigned to a group in Django and I can get the created groups using the below code, but could not use it to get the permissions assigned to them:

from django.contrib.auth.models import Group, Permission
groups = Group.objects.all()

I am not really sure how to get permissions assigned to these groups.

permissions = Permission.objects.all() gives me all the permissions, but I could not figure out how to get permissions assigned to a particular group.

Any pointers would be appreciated.

Solution 1

The Group model has a ManyToMany relationship with the Permission model, so you can do this

for group in Group.objects.all():
    permissions = group.permissions.all()
    # do something with the permissions

Solution 2

To get all permissions in all groups the current user belongs to use this:

all_permissions_in_groups = user.get_group_permissions()

To get all permissions related to a user including ones that are not in any group do this:

all_permissions = user.get_all_permissions()

For more details see Django documentation

do not do query in loop! in this case better to do something like this group_ids = Group.objects.all().values_list('id', flat=True) Permission.objects.filter(group__id__in=group_ids) this way u will always have only 2 queries.
