Question: I wanted when I chose the first option of 'status' , which in this case is empty, he returned all records normally , the problem is that it is returning
http://localhost:8000/proposal/?status=&search_box=
And it does not return anything . But in this case I want to return all .
What would be the best solution?

context = super(ProposalMixin, self).get_context_data(**kwargs)
context.update({'status_search_form': StatusSearchForm(), })
context['status'] = [(item, item_display, status_classes[item])
for item, item_display in STATUS_FILTER]
return context
