Tastypie for MongoDB error: get_resource_uri() takes exactly 2 arguments (1 given)

I have added tastypie to my Django project with a Mongodb backend. When I query /api/myresource

I get this error:

{"error_message": "get_resource_uri() takes exactly 2 arguments (1 given)", 
"traceback": "Traceback (most recent call last):\n\n

Solution

  • I encountered the same error when I upgraded my app from django 1.4 to 1.7 and upgraded django-tastypie too. One of my resources had it's own definition of get_resource_uri: get_resource_uri(self, bundle_or_obj).

    In newer versions of django-tastypie the second argument is now defaulted:

    def get_resource_uri(self, bundle_or_obj=None, url_name='api_dispatch_list'):

    So I changed my method signature to match the newer signature and all was well.

    It turns out I no longer needed to override the get_resource_uri() for my use case so I could just delete it.
