devdata_handler = Resource(DevDataHandler)
urlpatterns=patterns('',

def DevDataHandler(BaseHandler):
allowed_method = ('GET', 'POST', 'PUT', 'DELETE')
fields = ('title')
model = Data
def read(self, request):
data = {"msg":"Hi world"}
return data
it works if i did not include the devdata_handler = Resource(DevDataHandler) but i really need it...
do anyone can help me to solve my case?
thanks in advance
Handlers are classes, not functions. Change:
def DevDataHandler(BaseHandler):
to:
class DevDataHandler(BaseHandler):

Please help me.Thanks in advance....
Your identation is wrong, look in:
# Retrieve all of the associated pages.
# Note that filter returns >= 1 model instance.
pages = Page.objects.filter(category=category)
# Adds our results list to the template context under name pages.
context_dict['pages'] = pages
# We also add the category object from the database to the context dictionary.
# We'll use this in the template to verify that the category exists.
context_dict['category'] = category
Now you have an indentation error here:
def index(request):
category_list = Category.objects.order_by('-likes')[:5]
context_dict={'categories':category_list}
return render(request, 'rango/index.html', context_dict)
I am trying to create a simple API using django rest framework. In the view i have the following code.

It looks like you are hitting issue 2969. It should work if you upgrade from Django 1.6 to 1.6.11. However, please note that 1.6 is now end of life and does not receive security fixes, so ideally you should upgrade to the latest supported version of Django or the latest LTS.

This is the following exception that i need to manage :
'Commande' object has no attribute 'name'
I know that the 'name' attribute is in the class not the instance.
The fact that i can't figure out is, why the exception is raise with 'Commande' object and not 'Commands' object
