django rest framework create for self.request.user.<model>

Question

I have Folder model. Folder has foreignkey to User called folders.

In django rest framework I would like to create new Folder object. How do I specify "create object at self.request.user.folders"? under current (out of the box vanilla ModelViewSet) implementation I get error:

folder.folder.user_id may not be NULL

This indicates that a we are trying to create Folder object is without specifying a user.

Is there a built in way or will I need to override the create method and pass user in to the serializer as a argument?

Note that we don't want to pass user_id in request.DATA due to security issues.

models.py:

class FolderModel(Model):
    user = ForeignKey(User, related_name='folders')
    title = CharField(max_length=100)

views.py:

class FolderView(viewsets.ModelViewSet):
    serializer_class = serializers.FoldereSerializer
    model = FolderModel

    def get_queryset(self):
        return self.request.user.folders.all()

Please show the relevant models, so we can clearly see all relations. — mariodev

The original answer no longer works as of DRF 3.0, as the functions have changed. The relevant doc is here.

From the docs:

The pre_save and post_save hooks no longer exist, but are replaced with perform_create(self, serializer) and perform_update(self, serializer).

These methods should save the object instance by calling serializer.save(), adding in any additional arguments as required. They may also perform any custom pre-save or post-save behavior.

For example:

def perform_create(self, serializer):
    # Include the owner attribute directly, rather than from request data.
    instance = serializer.save(owner=self.request.user)
    # Perform a custom post-save action.
    send_email(instance.to_email, instance.message)
