Fault in url path?
Tank you for all the help! Still studying Django and trying to figure it out. In my program, I have a fault and I've tried different ways to go around it, but it persists...

How to use Django Backend Permissions in React Frontend?
I am implementing a simple object level permission using the django rest api backend and react.js frontend. I can successfully restrict the permission to a specific component in my backend by granting object-level permissions. class PostOwnerPermssion(permissions.BasePermission): """ Custom permission to only allow authors of a story to edit it """ def has_object_permission(self, request, view, obj): # Read permissions are allowed to any request, # so we'll always allow GET, HEAD or OPTIONS requests. if request.method in permissions.SAFE_METHODS: return True # Write and Delete permissions are only allowed to the owner of the story. return obj.author == request.user Now I want to hide some options in my react frontend based on the object-level permissions I granted in my backend. More concretely, a user other than the author should not see the "Edit Story" option in my frontend. I found this answer that looks quiet promissing but i have problems to map it to my example. How do I get the permission list of the user? In my backend only the author of story can edit the story. How can i pass this information from my django backend to my react frontend?
