I am creating a site, where people can register, but i only want them
to register, if they have a legit code. So let's say I give out the
three codes "code1", "code2" and "code3". How can I make sure, that
the user only gets registered, when the code gets vaildated?
Validate :registration_code => presence => true, ??? => ???
Do I have to write a custom method where I define all the possible
codes or how would you do it?
Thanks for your help!
