Django's template system allows creating tags which include other
templates:
{{{#!python
@register.inclusion_tag("results.html")
def show_results(poll):
choices = poll.choice_set.all()
return {"choices": choices}
}}}
However, with the addition of `simple_block_tag` in #35535, it would be
nice to combine the 2 into a `inclusion_block_tag`. This creates a form of
reusable component for Django template, combining context transformation,
rendering and internal content. There are a number of libraries in the
Django ecosystem which achieve this (eg `slippers`), so there's clearly an
appetite for this functionality.
{{{#!python
@register.inclusion_block_tag("results.html")
def show_results(content, poll):
choices = poll.choice_set.all()
return {"content": content, "choices": choices}
}}}
{{{#!django
{% show_results poll %}
This content gets captured too
{% endmysimpletag %}
}}}
The API matches the existing `inclusion_tag`, but with an additional
required `content` argument containing the (rendered) template content.
