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/
[Followup]
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

Using your example and your answer to Brandon’s response, this should work for you then:
template.html
{% block content %}
Hey {{stuff}} {{stuff2}}!
{{ other_content }}
{% endblock content %}
views.py
from django.http import HttpResponse
from django.template import Context, loader
from django.template.loader import render_to_string
def somepage(request):
other_content = render_to_string("templates/template1.html", {"name":"John Doe"})
t = loader.get_template('templates/template.html')
c = Context({
'stuff': 'you',
'stuff2': 'the rocksteady crew',
'other_content': other_content,
})
return HttpResponse(t.render(c))

Someone created a template tag that loads a view. I’ve tried it, and it works. The advantage of using that template tag is that you don’t have to rewrite your existing views.
