Trouble calling the form constructor from django createview - django

Question

I tried to pass the user( i.e, request.user) to my modelform constructor as given in this link.But i am getting
TypeError: __init__() got an unexpected keyword argument 'us'
error. Here's my view
class dealAdd(generic.CreateView):
form_class = dealForm
template_name='deals/deal_Add.html'
def get_context_data(self,**kwargs):
context=super(dealAdd,self).get_context_data(**kwargs)
llist=lead.objects.all()
clist=contacts.objects.all()
context.update({'leadob':llist,'contob':clist})
return context
def get_form_kwargs(self, *args, **kwargs):
kwargs = super(dealAdd, self).get_form_kwargs()
kwargs.update({'us': self.request.user})
return kwargs
and my form constructor
def __init__(self,*args,**kwargs):
usr=kwargs.pop('us')
super(dealForm,self).__init__(*args, **kwargs)
print(usr)
# print(self)
the traceback says that i have error at
context=super(dealAdd,self).get_context_data(**kwargs)
So is there a problem in my view?

Maybe it's because of the order.
Your CreateView call get_context_data first before get_form_kwargs. It means it 'pop' your 'us' before it updated it.
Just change usr=kwargs.pop('us', None) to avoid error or use try/except for it.
