✅

You can pass any number of variables to your custom template tag by using Python’s built in way of passing in multiple values from a list. Example:

from django import template

register = template.Library()

@register.tag('my_tag')
def do_whatever(parser, token):
    bits = token.contents.split()
    """
    Pass all of the arguments defined in the template tag except the first one,
    which will be the name of the template tag itself.
    Example: {% do_whatever arg1 arg2 arg3 %}
    *bits[1:] would be: [arg1, arg2, arg3]
    """
    return MyTemplateNode(*bits[1:])

class MyTemplateNode(template.Node):
    def __init__(self, *args, **kwargs):
        do_something()

    def render(self, context):
        do_something_else()

Hope that helps you out.

The easiest way to achieve this is to just use Python’s normal way of accepting a variable number of args:

@register.simple_tag()
def my_tag(*args):
  # do stuff with args, which is a list of all the arguments
  return 'what you want to output'

Then you can use it like you wanted:

{% my_tag arg1 arg2 arg3 %}
