Custom Template Filters
Django supplies a lot of useful filters that we can use in our templates while we are working on our projects. But what if someone wants to format a specific piece of text and render it with different fonts? Or say if someone wants to translate an error code to a user-friendly error message based on the mapping of the error code in the backend. In these cases, predefined filters do not suffice, and we would like to write our own filter that we can reuse across the project.
Luckily, Django supplies an easy-to-use API that we can use to write custom filters. This API provides developers with some useful decorator functions that can be used to quickly register a Python function as a custom template filter. Once a Python function is registered as a custom filter, a developer can start using the function in templates.
