Hi, I am using following to validate the contact name like : validates_format_of :merchant_contact_firstname, :with => /^([a-zA-Z ]+)$/, :message=>''First name is not valid.'' But it gives error even if it is left blank. Acually, it is optional but if it is present then it can have only alphabets. How can I validate both presence and format separately in model? Thanks. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi,
I would use:
validates_format_of :merchant_contact_firstname, :if => Proc.new {|c|
not c.merchant_contact_firstname.blank?}, :with => /^([a-zA-Z]+)$/,
:message=>''First name is not valid.''
Meaning that when the merchant_contact_firstname is not blank it gets
evaluated with the regex.
Kind regards,
Nick Snels

Re: how to validate only presence or format
I believe tweaking the regexp just a little bit is easier, like this: /^(|[a-zA-Z ]+)$/ or /^([a-zA-Z ]*)$/ Judging by a quick test done in irb both seem to work just fine. Hope it helps!
