Manage object permissions by defining methods in Django Model

Project description

django-reinhardt Documentation Status Updates

There are many object permission backends like django-guardian or django-permission.

But some time, it is needed to define permissions as not just object-user relationship.

django-reinhardt make you handle object permissions by defining methods in your django model


Use pip like:

$ pip install django-reinhardt


Add extra authorization backends in your

    'django.contrib.auth.backends.ModelBackend', # default

It’s done. you don’t need to add any app or migrate anything.

Assume that Inquiry model needs to have two permission: change_inqury, view_inquiry

class Inquiry(models.Model):

    writer = models.ForeignKey(settings.AUTH_USER_MODEL)
    text = models.TextField()
    pub_date = models.DateTimeField(auto_now_add=True)

    def is_changeable_by(self, user):
        return self.writer == user or user.is_staff

    def is_viewable_by(self, user):
        return self.writer == user

Then you can just define methods having user parameter, decorated by object_permission.

Now the following codes will work as expected:

user1 = get_user_model().objects.create(
user2 = get_user_model().objects.create(
user3 = get_user_model().objects.create(
inquiry = Inquiry.objects.create(
    text='How can I delete my account?'

assert user1.has_perm('yourapp.change_inquiry', obj=inquiry) == True
assert user2.has_perm('yourapp.view_inquiry', obj=inquiry) == False
assert user3.has_perm('yourapp.change_inquiry', obj=inquiry) == False
assert user3.has_perm('yourapp.view_inquiry', obj=inquiry) == True
