Tastypie: getting "AttributeError: 'NoneType' object has no attribute '_clone'" Error

When I try to issue a GET to my model (using TastyPie), I get the following traceback error: 

File "/Library/Python/2.7/site-packages/tastypie/resources.py", line 
2141, in get_object_list
return self._meta.queryset._clone()
AttributeError: 'NoneType' object has no attribute '_clone'

Below is my resources.py file for the relevant Model. 

from tastypie.resources import ModelResource
from swtr.models import Com

class ComResource(ModelResource):
    class Meta:
        query_set = Com.objects.all()
        resource_name = 'com'
        object_class = none

I'm particularly confused given that Com.objects.all() returns at least one record that I created and saved within the python shell. So I'm not sure why the queryset is being returned as a NoneType.

Solution

  • You have misspelled some fields in your ComResource's Meta class.

    Try renaming query_set to queryset and give object_class a value of None, not none:

    from tastypie.resources import ModelResource
from swtr.models import Com


class ComResource(ModelResource):
    class Meta:
        queryset = Com.objects.all()
        # __^
        resource_name = 'com'
        object_class = None
        # _____________^
