Let's start with the reasonable simplifying assumption that filters
aren't totally broken in Django.
So arguments are passed to them correctly if you write a filter similar
to the documentation (which you appear to have done). Which means the
other possibility is that the data you're passing in actually is a
string of length 0 (or resolves to that, since if the variable didn't
exist, that would also be the apparent behaviour).
For debugging purposes, set up a simple template that is passed a
context variable containing a string you know exactly (e.g. make the
context something like {"foo": "this is a string"}) and then try out
your filter on that. You're attempting to debug something in a
complicated setup here, rather than in an environemtn that is as simple
as possible. Don't have the extra variable of having to worry about
whether "request" exists in the context and, if so, whether
"request.path" contains anything.
