This appears to be the incorrect line – here, you set 'DIRS' to a list
containing a single item, which is a tuple containing a path. The
problem is that you wrap the path twice. Django only expects a simple
list of paths, so if you just drop the tuple wrapping the path, you
should be fine::
'DIRS': [os.path.join(BASE_DIR, 'templates')],

This is not strictly related to your problem, but I would strongly
advise not to render templates used as HTTP responses in this way.
Instead, you should be using either the render shortcut [1], or
TemplateResponse [2]. They are mostly equivalent, and both accomplish
the same thing as the above code, only with a single function call.
More often than not, less code is better.
Also, unlike TemplateResponse and render, the code above will not
apply context processors, unless you change that Context to a
RequestContext, which is something that's super easy to forget, and
I've actually seen people get bitten by that in the past, and spend a
lot of time trying to figure out why their templates are not behaving.
Cheers,
