Reverse request query string back to defined pattern

Question

I have a route configured like this in my app:

config.add_route('book', 'book/{id}).

When I make a GET request, e.g localhost:8000/book/2, I would like to output route pattern like the one defined in config, so the output would be 'book/{id}'.

I have tried regex, but maybe there are better ways.

What would be the best way to achieve that?

Answer 1

Use request.matched_route.pattern. I found it by using the pyramid_debugtoolbar, searching for "route", and found it under the Request Vars tab with its attributes listed.
