get_context_data method Django

Question

# views.py
from django.views.generic import ListView
from books.models import Publisher

class PublisherList(ListView):
    model = Publisher
    context_object_name = 'my_favorite_publishers'

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context['number'] = random.randrange(1, 100)
    return context

What does calling get_context_data with super() return?

What type of information?

And is the returned context from get_context_data given the contexT_object_name 'my_favorite_publishers'?

Answer 1

The .get_context_data(..) method [Django-doc] returns a dictionary that contains the context that will be passed to the template for rendering.

A ListView [Django-doc] will by default make a dictionary with the following keys and values:

• 'view': maps to the instance of this view;
• 'paginator': the paginator object if you paginate, None otherwise;
• 'page_obj': the page object of the current page if you paginate, None otherwise;
• 'is_paginated': True if you paginate, False otherwise;
• 'object_list': the (optionally) paginated queryset that is made by the ListView; and
• context_object_name: if you specified a context_object_name (or you have overwritten get_context_object_name and it does not return None, it will associate this with the (optionally) paginated queryset as well.
