DjangoModelPermissionsOrAnonReadOnly
DjangoModelPermissionsOrAnonReadOnly permission class is the same as that of the DjangoModelPermissions class except it allows unauthenticated users to have read-only access to the API.
Let’s import the DjangoModelPermissionsOrAnonReadOnly class.
from rest_framework.permissions import DjangoModelPermissionsOrAnonReadOnly
Now you can add the permission class to RobotDetail and RobotList class. The code is as follows:
Python3
class RobotList(generics.ListCreateAPIView): permission_classes = [DjangoModelPermissionsOrAnonReadOnly] queryset = Robot.objects. all () serializer_class = RobotSerializer name = 'robot-list' class RobotDetail(generics.RetrieveUpdateDestroyAPIView): permission_classes = [DjangoModelPermissionsOrAnonReadOnly] queryset = Robot.objects. all () serializer_class = RobotSerializer name = 'robot-detail' |
Let’s try to retrieve robots without providing any credentials. The HTTPie command is as follows:
http :8000/robot/
Output
Adding Permission in API – Django REST Framework
There are many different scenarios to consider when it comes to access control. Allowing unauthorized access to risky operations or restricted areas results in a massive vulnerability. This highlights the importance of adding permissions in APIs.
Django REST framework allows us to leverage permissions to define what can be accessed and what actions can be performed in a meaningful or common way. The permission checks always run at the beginning of every view. It uses the authentication information in the ‘request.user’ and ‘request.auth’ properties for each incoming request. If the permission check fails, then the view code will not run.
Note: Together with authentication, permissions determine whether to grant or deny access for an incoming request. In this section, we will combine Basic Authentication with Django REST framework permission to set access control. You can refer Browsable API in Django REST Framework for Models, Serializers, and Views
