How to use context with class in CreateView in django?

Before i have:

#views.py
from django.views.generic import CreateView
from cars.models import *

You have to use get_context_data

class CreateCar(CreateView):
    info_sended = False
    template_name = 'create_car.html'
    model = Car
    success_url = 'create_car' #urls name

    def form_valid(self, form):
        self.info_sended = True
        return super(CreateCar, self).form_valid(form)

    def get_context_data(self, **kwargs):
        ctx = super(CreateCar, self).get_context_data(**kwargs)
        ctx['info_sended'] = self.info_sended
        return ctx

If you see the django source CreateView inherits from BaseCreateView this one inherits from ModelFormMixin in turn this one inherits from FormMixin and this one inherits from ContextMixin and the only method this one defines is get_context_data. Hope this helps you.

PD: This may be a bit confusing for better understanding of inheritance in Python feel free of read this article about MRO.
