I am trying to write a model validates_format_of that will accept a field containing only certain characters. I want the field to only allow the following characters: a-z, A-Z, 0-9 and the '_', '@', '.' and '-' characters. I have hunted around a bit and came up with this: validates_format_of :password, :with => /^([a-zA-Z0-9.\-_@])+ $/, :message => "illegal." Is that correct? I tested it a bunch, but I want to ask the community to be sure. Thanks, Nicholas P. Mueller

I'm hardly an expert, but it looks good to me. I like to test my regex using this website: http://www.cuneytyilmaz.com/prog/jrx/ Just paste in your regex without the leading and trailing / marks, and then you can test input using the bottom box. It's fun =D HTH, Ryan -- View this message in context: http://www.nabble.com/regex-help-t1764703.html#a4803438 Sent from the RubyOnRails Users forum at Nabble.com.

You can shorten it a bit if you like though ;) /^([\w.\-_@])+$/ -Ezra
