You can leverage Django's template loader to render your template, including whatever context you pass to it, as a string and then save that out to the filesystem. If you need to save that file on an external system, such as Amazon S3, you can use the Boto library.
Here's an example of how to render a view to a file, using an optional querystring parameter as the trigger...
from django.shortcuts import render
from django.template.loader import render_to_string
def my_view(request):
as_file = request.GET.get('as_file')
context = {'some_key': 'some_value'}
if as_file:
content = render_to_string('your-template.html', context)
with open('path/to/your-template-static.html', 'w') as static_file:
static_file.write(content)
return render('your-template.html', context)
