I am working on some Rails internals and have a place where given a ActionDispatch::Journey::Route object, I need the path prefix.

If I run this:

pp route.path.spec.to_s

I get this:

/my-endpoint(.:format)

But the full path is missing and I need the stuff in the parenthesis omitted, so with this route being mounted at /api, I need this in stead:

/api/my-endpoint
