Forum: Ruby on Rails Why are anchor characters not allowed in routing requirements ?

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.
