Question

In django I have a view that fills in a template html file but inside the html template I want to include another view that uses a different html template like so:

{% block content %}
Hey {{stuff}} {{stuff2}}!

{{ view.that_other_function }}

{% endblock content %}

Is this possible?

Yes, you need to use a template tag to do that. If all you need to do is render another template, you can use an inclusion tag, or possibly just the built in {% include ‘path/to/template.html’ %}

Template tags can do anything you can do in Python.

https://docs.djangoproject.com/en/3.0/howto/custom-template-tags/

You can use the render_to_string method:

from django.template.loader import render_to_string
content = render_to_string(template_name, dictionary, context_instance)

You’ll either need to resolve the request object from the context, or hand it in as an argument to your template tag if you need to leverage the context_instance.

Followup Answer: Inclusion tag example

Django expects template tags to live in a folder called ‘templatetags’ that is in an app module that is in your installed apps…

/my_project/
    /my_app/
        __init__.py
        /templatetags/
            __init__.py
            my_tags.py

#my_tags.py
from django import template

register = template.Library()

@register.inclusion_tag('other_template.html')
def say_hello(takes_context=True):
    return {'name' : 'John'}

#other_template.html
{% if request.user.is_anonymous %}
{# Our inclusion tag accepts a context, which gives us access to the request #}
    <p>Hello, Guest.</p>
{% else %}
    <p>Hello, {{ name }}.</p>
{% endif %}

#main_template.html
{% load my_tags %}
<p>Blah, blah, blah {% say_hello %}</p>

The inclusion tag renders another template, like you need, but without having to call a view function. Hope that gets you going. The docs on inclusion tags are at: https://docs.djangoproject.com/en/3.0/howto/custom-template-tags/#inclusion-tags
