Django provides base view classes which will suit a wide range of applications. All views inherit from the View class, or methods (such as get_context_data) in your subclass to provide new values or methods. Consider, for example, a view that just displays one template, about.html. Django has a generic view to do this - TemplateView - so we can subclass it, and override the template name. How to Create an App in Django? Method 1: Using get_context_data method.

The big advantage these javascript libs offer is interactivity: You can hover over points to see their values making studying the graph much easier. Yet, there are times where you need some simple (or not so simple) graphs and don't. We only had to provide a get_context_data() implementation to add context to the template.

If we fix that, we have the problem that object doesn't have get_context_data so will barf Django's FormView particularly has a lot of methods that can be accessed. These are some common methods you'll want to understand: get_context_data; get_form_class; get_form_kwargs; get_success_url; form_valid; form_invalid; post; Part of understanding the flow of data is understanding how data moves between the user and the database. This means understanding how data is retrieved from the database, passed into the view, and displayed in the template. Likewise from the other way around. Django will only display messages with a level greater than 20 (INFO) by default. If you want to display DEBUG messages: from django.contrib.messages import constants as message_constants MESSAGE_LEVEL = message_constants.DEBUG . Or if you are running into circular imports, you can add the constant value directly: MESSAGE_LEVEL = 10 # DEBUG Usag

  1. We will be using generic views for passing data to a template. You can different generic views like ListView, DetailView, View, etc. And with those generics views, you can use different methods like get, get_context_data, get_queryset.
