Hi,
I am developing an application in rails 3.0

I have post Model
class Post < ActiveRecord::Base
  validates :name ,  :presence => true
end

I have added the presence of validation on post name.
It shows me error that "Name can't be blank"

I have to give the custom message for the user so I have written like as
follows:-

class Post < ActiveRecord::Base
  validates :name ,  :presence => true , :message=>"Post name can't be
blank."
end

But it is giving me error:-
"Unknown validator: 'message'"

Can anyone tell me How to give the custom message in rails 3 model
validations?

Thanks,
Mike
