Django: class-view lacking attribute COOKIES

I am currently playing around with REST and backbone.js and ran into this issue:

'LoginView' object has no attribute 'COOKIES'

Here comes the following code for might have caused the problem. I have commented out a few things in the javascript, since I wanted it to load directly to the server instead, but I thought it would be just as good to bring it along.

I can also add that I have checked for the csrf-token in the form and it is there.

class LoginView(TemplateView):
form_class = LoginForm
template_name = 'front/login.html'
initial = {'key': 'value'}

def get(self, request, *args, **kwargs):
form = self.form_class(initial=self.initial)
return render(request, self.template_name, {'form': form})

@api_view(['GET', 'POST'])
def post(self, request, *args, **kwargs):
form = self.form_class(request.POST)
print request.COOKIES('csrftoken')
print request.POST.get('csrfmiddlewaretoken')
if form.is_valid():
#if not is_safe_url(url=redirect_to, host=request.get_host()):
# redirect_to = resolve_url(settings.LOGIN_REDIRECT_URL)
print request.POST.get('email')
#user = self.get_user(request.POST.get('email'))
#print user
#auth = UserDataAuthentication(request, user)
user = authenticate(email=request.POST.get('email'), password=request.POST.get('password'))
if user is not None:
auth_login(request, user)
return Response(user, status=status.HTTP_201_CREATED)
return HttpResponseRedirect('/login/')


var csrftoken = $('meta[name="csrf-token"]').attr('content');
SigninView = Backbone.View.extend({
events: {
//"click button[type=submit]": "sendRequest"
sendRequest: function( event ){
var csrftoken = $.cookie('csrftoken');
var url = '/login/validate/';
var email = $("#id_email").val();
var password = $("#id_password").val();
var items = {
email: email,
password: password,
csrfmiddlewaretoken: csrftoken
data: items,
success: function (data) {
var json = $.parseJSON(data);
error: function (xhr, textStatus, error) {
$("#form_error").css('padding','7px').css('border-radius','4px').html('Error recieved: ' + error).fadeIn();
console.log("Status: "+textStatus);
console.log("Type: "+error);
var signin_view = new SigninView({
el: $("#login_form")

We are two people working on this, I have taken upon myself to work with Python, while my friend takes care of the js-part. I have yet to experience enough of Django to actually find what might have caused an error to arise due to cookies. I try, most of the time, to stay away from cookies, if I can, but it seems difficult here.

And of course: The traceback:

Exception Value: 'LoginView' object has no attribute 'COOKIES'

You used functions decorators on a method.

This won't work: the function as returned by the decorator expects its first argument to be a request, and receives self instead.
