Can I combine Create and List class based generic views using mixins?
I'm looking for the easiest way to combine List and Create functionally with generic class views.
I want to have a page that has an item list and a form to add a new item on the bottom.I thought that mixin architecture would allow to com开发者_开发问答bine necessary classes but I had no luck yet.
This almost works:
class ResourceListView(ListView, BaseCreateView):
context_object_name = 'resources'
model = Resource
form_class = ResourceForm
But form
isn't accessible inside template and the thing crashes on invalid output (when form is valid, it's fine).
Is there a simple way to combine some of the mixins into a view-and-create View, or do I have to roll out my own?
Note: I no longer advocate this solution, as this is a much cleaner one.
By trial and error (and looking at Django source), I wrote this:
class ListCreateView(ListView, BaseCreateView):
def get_context_data(self, **kwargs):
self.object = None
self.object_list = self.get_queryset()
form_class = self.get_form_class()
form = self.get_form(form_class)
kwargs.update({'object_list': self.object_list, 'form': form})
context = super(ListCreateView, self).get_context_data(**kwargs)
return context
Works fine both for creating and listing (although it may issue a few extra database calls, not sure).
