Programmatically render inclusion tag in Django

Question

Django provides the render(…) shortcut function which essentially takes a template name and a context and returns an instance of HttpResponse containing the rendered template string.

Is there an official way to do the same thing with an inclusion tag? That is, instead of supplying a template name I would like to supply the name of an inclusion tag that then gets rendered with its own context (i.e. what the tag function returns) plus an optional additional context. For example, let's consider the following tag:

# myapp/templatetags/myapp.py

@register.inclusion_tag('myapp/mytemplate.html')
def my_inclusion_tag(some_paramter):
    return {
        'some_parameter': some_parameter
    }

Then I would like to be able to do something like

http_response = render_tag(request, 'myapp.my_inclusion_tag', {'additional_context': value})

where the entire context would be {'some_parameter': some_parameter, 'additional_context': value}.

In case someone encounters a similar problem, this is the solution I came up with:

from django.template import Template, Context

# "micro template" containing the inclusion tag
template_string = f"{{% load myapp %}}{{% my_inclusion_tag %}}"
template_context = {'key1': 'value1', …}
html = Template(template_string).render(Context(template_context))
