Using a regex to validate an email format is in most cases a bad idea, the 2 proposed regexes won't for example recognize quoted local parts, which are valid (e.g. "f...@bar"@rails.info is a valid address). There's a validate_email_format_of plugin on github[1] which works fine on rails2, I think there is a branch/fork for rails3 somewhere too. Another method would be to just drop an EmailValidator into your lib so that you can reuse it at other places in your rails app, have a look at [2] (yes, it still is a regex and only matches what the RFC refers to as "addr-spec" as opposed to a "full" address, but a not-so-bad one). Anyway, I'm a little surprised that rails3 having gone from TMail to Mail hasn't added a validator that would re-use the one already present in Mail… Regards, Felix [1] http://github.com/alexdunae/validates_email_format_of [2] http://lindsaar.net/2010/1/31/validates_rails_3_awesome_is_true -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
