Full message for error_messages_for

I found this somewhere while looking around for the easiest way to provide my own full message for the rails error_messages_for output. Basically what we are going to do here is provide a humanized string for a variable of the model, and when the error message is printed out, it will display that message. This give more control instead of just having “Email is required.”

class Person < ActiveRecord::Base

  HUMANIZED_ATTRIBUTES = {
    :name => "Please provide a name for this person.",
    :email => "You must specify an email address."
  }

  def self.human_attribute_name(attr)
    HUMANIZED_ATTRIBUTES[attr.to_sym] || super
  end

  validates_presence_of :name,  :message=>''
  validates_presence_of :email, :message=>''

end
