如何添加django管理员只读权限？

from django.contrib.auth.models import Permission

class ReadOnlyPermission(Permission):
    class Meta:
        proxy = True
        permissions = (
            ("read_only", "Can only view data"),
        )

from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import Group

UserAdmin.fieldsets += (("Permissions", {"fields": ("user_permissions",)}),)
admin.site.unregister(Group)
admin.site.register(ReadOnlyPermission)

python manage.py makemigrations
python manage.py migrate

python manage.py createsuperuser
