[FIXED] Django: Passing variable from get_context_data() to post()

Issue

The variable is defined inside get_context_view() since it requires an id to access correct database object:

class FooView(TemplateView):
  def get_context_data(self, id, **kwargs):
    ---
    bar = Bar.objects.get(id=id)
    ---

  def post(self, request, id, *args, **kwargs):
    # how to access bar?
    # should one call Bar.objects.get(id=id) again?

What would be the way to pass bar variable to post()?

Tried to save it as FooView's field and access it via self.bar, but this doesn't do the trick. self.bar is not seen by post()

Solution

You should reverse it. If you need bar in post(), you need to create it there:

class FooView(TemplateView):
    def get_context_data(self, **kwargs):
        bar = self.bar

    def post(self, request, id, *args, **kwargs):
        self.bar = Bar.objects.get(id=id)
        ...

post() is called before get_context_data, that's why post doesn't see it if you define it in get_context_data.
