URL routing regex

Question

I'm trying to create a snippet of regex that will match a URL route.

Basically, if I have this route /users/:id I want /users/100 to match, but /users/100/edit not to match.

This is what I'm using now: users/(.*)/ but because of the greedy match it's matching regardless of what's after the user ID. I need some way of "breaking" the match if there's an /edit or something else on the end of the route.

I've looked into the Regex NOT operator but with no luck.

Any advice?

Are you just trying to collect digits?

You could use users/(\d*)/

And this one is how you would do it if you wanted to collect everything until a /, and it uses a NOT, ^/users/[^/]*$

Had to modify it slightly for my use: `^/users/[^/]*/$` but this is exactly what I needed to know, thank you! :) – James Dawson Oct 24 '12 at 00:18

You can use negative lookahead:

users/(.*)/(?!edit)

This will always require a trailing slash however. Maybe a better solution would be:

users/(\d+)(?!/edit)

See this post for more information.
