I am learning to use Validations and am using validates_length_of to check a field value is no longer than 240 characters. I want to be able to produce a message back to the user telling them that the value they entered was x characters too long. Does anyone know how I can work with the value and its length? validates_length_of :name, :maximum => 240, :message =>
:message => "Length is #{name.length}, max allowed is 240"

Thanks for the reply, That doesn''t give me the value for name it just gives back the name of the model. i.e Task so the length given is 4. Any ideas?
