With the growing uptake of technologies like HTMX, I would like to see an
additional parameter added to render_to_string(). In my rewritten
definition of render_to_string() below (taken from the docs), I have named
the parameter “part”. In rendering portions of a template for responses to
ajax calls, these template portions end up being stored in separate template
snippet files and then {% include(d) %} in the main template. I think that
keeping everything related to a view in a single template file is much more
desirable. Therefore, just include part=selector in order to pull out the
part of the template that is needed for rendering. The file structure for
managing templates would become much simpler with this approach.
render_to_string(template_name, part=None, context=None, request=None,
using=None)
<https://docs.djangoproject.com/en/4.0/topics/templates/#django.template.loa
der.render_to_string> ¶
render_to_string() loads a template like
<https://docs.djangoproject.com/en/4.0/topics/templates/#django.template.loa
der.get_template> get_template() and calls its render() method immediately.
It takes the following arguments.
template_name
The name of the template to load and render. If it’s a list of template
names, Django uses
<https://docs.djangoproject.com/en/4.0/topics/templates/#django.template.loa
der.select_template> select_template() instead of
<https://docs.djangoproject.com/en/4.0/topics/templates/#django.template.loa
der.get_template> get_template() to find the template.
part
An optional CSS selector that will be used to cause only the portion of the
template that matches the selector to be rendered.
context
A <https://docs.python.org/3/library/stdtypes.html#dict> dict to be used as
the template’s context for rendering.
request
An optional
<https://docs.djangoproject.com/en/4.0/ref/request-response/#django.http.Htt
pRequest> HttpRequest that will be available during the template’s rendering
process.
using
An optional template engine
<https://docs.djangoproject.com/en/4.0/ref/settings/#std-setting-TEMPLATES-N
AME> NAME. The search for the template will be restricted to that engine.
