Simple Etag and Last-Modified mixins for class based views.

Simple ETag and Last-Modified mixins for class based views.

What is Django Conditional Views?

Django Conditional Views builds off of the built in django conditional view processing machinery to provide simple mixins for class based views that implement support for the ETag and Last-Modified conditional request headers.

Features

Inherit one of these mixins to make your TemplateView’s, DetailView’s, or ListView’s:

1. Calculate and append ETag and/or Last-Modified headers to the response and;

2. Respond with a 304 Not Modified or a 412 Precondition Failed to requests that provide conditional response headers such as If-Modified-Since

Helpful Defaults

• ETags are automatically generated from the response.content.

• ETag generation can be customized both before and after the response is rendered.

• The Last Modified header is automatically set from the last modified timestamp of the template.

• In the case of the DetailView and ListView mixins, the Last Modified header may also be configured to get the last modification timestamp from a field on the model, in which case the lastest of that or the template’s last modified timestamp will be used.

Getting Started
