I think, I still missunderstand you. But perhaps this is, what you need:
You want to iterate through errors:
@user.errors.each do |attr, message|
do something with attr and message
end
If you want an array of all full_messages, use:
@user.errors.full_messages
(how they are handling it in this episode:
http://railscasts.com/episodes/211-validations-in-rails-3)
@user.errors.generate_message(:firstname)
Or if you need the other methods of @user.errors, look here:
http://api.rubyonrails.org/
ActiveModel::Errors
Is this what you need?
PS:
validates :firstname, :presence => true, :message => "First name is missing"
I think this is confused mix of old
validates_presence_of :firstname, :message => message
and newer sexy validations
validates :attribute, :presence => options_hash/true/array/
if you look in the source:
75 validations =defaults.slice!(:if,:unless,:on,:allow_blank,:allow_nil)
only these 5 options are possible global-options. :message is not one of them.
So I am sure, your way won't do what you want it to do.

Yes. But I've also seen alidates :firstname, :presence => true, :message
=> "First name is missing"
However that's not my problem. How do I get hold of the error message?
