Chapter 7. Custom Tags and Filters

Django ships with a number of built-in template tags and filters that fit the needs of most web-publishing situations. Filters are typically used to modify the output of a value in the template, and tags let you do just about anything you want.

At some point in your development, you may come across a situation or need that cannot be handled by the default template tags and filters. Luckily, Django provides a way to write our own extensions to the template engine by creating custom tags and filters.

In this chapter, we will:

  • Review how the default template tags and filters are implemented

  • Learn the syntax for writing our own template tags and filters

  • Learn where to put our custom files in our project and how Django loads them

  • Create and implement custom filters to format currency, remove profanities, and test if an item is in a list

  • Create and implement custom tags to write output and introduce new variables into the context from within the template
