Wrapping template tag for django

Wrapping template tag for django

Documentation

Wrapper tag provides base class for wrapping tag. Wrapping tag which can have defined keyword arguments, keyword arguments group in declarative way, and provide multiple steps of template rendering.

Example:

from django import template
register = template.Library()

@wrapper_tag.register_tag(register)
class ExampleTag(wrapper_tag.Tag):

    title = wrapper_tag.Keyword(help_text=('title for example tag'))

    class Meta:
        template = "<div{{ title__rendered }}>{{ content }}</div>"

    def render_title(self, argument, data, context):
        if argument.name not in data:
            return
        return ' title="{title}"'.format(data[argument.name])

And then simply use tag in template:

{% example title="Some informational title" %}
    Content
{% end:example %}

This will yield to:

<div title="Some informational title">
    Content
</div>

That was just a simple eample what wrapper tag can do. It can do much more than that.
