Question

I want to provide some help to my users for filling out forms. So let’s assume I have a model customer with

validates_presence_of :email
validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => 'must be a valid email address'

Now I want to get the error messages that belong to :email without actually invoking them. So I need the string “(email) can’t be blank” and “(email) must be a valid email address” to print them out as tooltips on my registration forms.

So is there any way to obtain them?

Answer 1

Customer.validators will get you an array of validators, then you can iterate them and get, for example: Customer.validators[0].options[:message].
