Python/Django: as_view() takes 1 positional argument but 2 were given -

-

i have written as_view() in django project in 2 positional arguments given submit form. when rendering template raising type error : as_view() takes 1 positional argument 2 given. appreciate helping me in solve this.

views.py:

class auctionview(loginrequiredmixin, multipleformsview):     template_name = 'loggedin_load/active_deals.html'     form_classes = {'accept_bid': auctionform,                 'accepted': acceptedform}     success_url = '/live_bids/'       @method_decorator(user_passes_test(not_in_company_group, login_url='/login/'))     def dispatch(self, *args, **kwargs):         return super(auctionview, self).dispatch(*args, **kwargs)       def accept_bid_form_valid(self, request, post_id, bid_id, form):          accept_bid = form.save(commit=false)         accept_bid.bid = bid         accept_bid.post = post         accept_bid.post_owner = request.user         accept_bid.save()         form.save()         return form.accept_bid(self.request, redirect_url=self.get_success_url())      def accepted_form_valid(self, form):         accepted = form1.save(commit=false)         return form.accepted(self.request, user, self.get_success_url())

urls.py:

url(r'^post/(?p<post_id>[\w-]+)/bid/(?p<bid_id>[\w-]+)/$', auctionview.as_view, name='accept_bid'), 

url(r'^post/(?p<post_id>[\w-]+)/bid/(?p<bid_id>[\w-]+)/$', auctionview.as_view(), name='accept_bid'),
