Tastypie 'NoneType' object has no attribute '_clone' error
Rajeev Nair
I am using tastypie (v0.11) and django(v1.6.1) on windows operating system using pycharm IDE. I am using virtual environment within pycharm. The django model and related ORM cruds work fine and I am using postgresql with psycopg2 driver. Now, I am trying to create a simple REST based request-response framework utilizing json payloads. While trying to test the REST request-response, I keep getting a strange error in the response. The error is as follows:
**AttributeError 'NoneType' object has no attribute '_clone' error.** The url used for testing is
http://localhost:8000/api/comment?format=jsonI have already spent a day trying to figure what's wrong. I tried using two other versions of tastypie (v0.10 and v0.9), but the error remains. Any help and guidance will very much be appreciated. Many thanks !!
My code is as follows:
The django model class
from django.db import models
class Comment(models.Model):
ID=models.BigIntegerField(primary_key=True)
text=models.CharField(max_length=200)The tastypie resource class
from tastypie.resources import ModelResource
from pie.models import Comment
class CommentResource(ModelResource):
class Meta:
queryset=Comment.objects.all()
resource_name="comment"The urls.py file
from django.conf.urls import patterns, include, url
from pie.api import CommentResource
from django.contrib import admin
admin.autodiscover()
res=CommentResource()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^api/', include(res.urls)),
)
