Rails 3 - Pass a parameter to custom validation method

Question

I am looking to pass a value to a custom validation. I have done the following as a test:

validate :print_out, :parameter1 => \'Hello\'

With this

Answer 1

You could try

validate do |object_name|
  object_name.print_out "Hello"
end

Instead of your validate :print_out, :parameter1 => 'Hello'.
