[Django]-How to write own methods in class based views and call the methods in urls

You need to call methods in get(), post() or whatever the HTTP request is. There isn’t a start HTTP request so Django won’t call that.

You can do the following in your view:

def get(self, request, *args, **kwargs):
    return self.start()

This return the result of self.start() whenever you visit your view with a HTTP GET request.
