Ok, so I'm trying to replace a ' character with \' in a ruby string. I have working code, but it was 
*way* too painful getting there for my taste.

Take a look:

ree-1.8.7-2010.02 :001 > single_quote = "\'"
 => "'" 
ree-1.8.7-2010.02 :003 > single_quote.gsub(/'/, "\\\'")
 => "" 
ree-1.8.7-2010.02 :004 > single_quote.gsub(/'/) {|c| "\\'"}

web apps nearly always end up needing a plethora of little javascript helper methods: you know, auto-complete forms, populating defaults, validations, etc.  these aren't API calls properly, just little tidbits of functionality needed to make the views work.

there is always a question of which controller to hang these methods off of.  do you make a global helper controller for all this stuff?  do you hang them off the controller in question?  how to do share the backend of javascript helper methods across controllers?
