Django Classy Tags

pypi build coverage

The goal of this project is to create a new way of writing Django template tags which is fully compatible with the current Django templating infrastructure. This new way should be easy, clean and require as little boilerplate code as possible while still staying as powerful as possible. Some features:

  • Class based template tags.
  • Template tag argument parser.
  • Declarative way to define arguments.
  • Supports (theoretically infinite) parse-until blocks.
  • Extensible!

Example

This is how a tag looks like using django-classy-tags:

from classytags.core import Options
from classytags.helpers import AsTag
from classytags.arguments import Argument
from django import template

register = template.Library()

class Hello(AsTag):
    options = Options(
        Argument('name', required=False, default='world'),
        'as',
        Argument('varname', required=False, resolve=False)
    )

    def get_value(self, context, name):
        return 'hello %s' % name

register.tag(Hello)

That's your standard hello world example. Which can be used like this:

  • {% hello %}: Outputs hello world
  • {% hello "classytags" %}: Outputs hello classytags
  • {% hello as myvar %}: Outputs nothing but stores hello world into the template variable myvar.
  • {% hello "my friend" as othervar %}: Outputs nothing but stores hello my friend into the template variable othervar.
