Did you really mean "Client Side Validation" as you have in your Subject: line? That means JavaScript, not ActiveRecord validations? Even if you do use Client Side validation, you really need to do Server Side as well to guard against hacks. Read about Server Side here: http://guides.rubyonrails.org/active_record_validations.html Follow Robert's advice as well and learn some regular expression magic. You'll need it for either side. I'm wondering altogether though, why the need to validate this? If the user is typing a stream of text, they may or may not wish to include # at some point other than as a hash tag; I think perhaps you maybe just want to extract the hash tags that match your spec, rather than declare the input invalid? I'm just speculating here, I obviously don't know what your application is trying to do. It's the concept of hash tags from twitter and now other services that I'm thinking of; a way to denote a specific key word to search on in a stream of text. Anyway, more code/design/info is needed to help more, I think. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
