Why are anchor characters not allowed in routing requirements ?

[deepak]

hi,

I have a route which says:

UUID_REGEX = /^([0-9a-f]{8})-([0-9a-f]{4})-([0-9a-f]{4})-([0-9a-f]{2})([0-9a-f]{2})-([0-9a-f]{12})$/

resources :checkout, :only => [:show, :create], :constraints => { :id => UUID_REGEX }

I get an error saying:

Regexp anchor characters are not allowed in routing requirements

full stacktrace is at https://gist.github.com/4578503

Why are anchor characters not allowed in routing requirements ?

I am using Rails 3.2.11

This is because these regexes are now automatically anchored at the start and end of the path component. Just removing the anchors from your regex fixes it.
