Form handling with class-based views

Basic forms

Notes:

• FormView inherits TemplateResponseMixin so template_name can be used here.
• The default implementation for form_valid() simply redirects to the success_url.

Model forms views + form = formview

You don’t even need to provide a success_url for CreateView or UpdateView - they will use get_absolute_url() on the model object if available.

Using mixins with class-based views

For this reason, Django also provides a number of mixins that provide more discrete functionality. Template rendering, for instance, is encapsulated in the TemplateResponseMixin. The Django reference documentation contains full documentation of all the mixins.
