How to validate text isn't blank in Rails

Question

if I do

  validates :body, :presence => true, :length => {:maximum => 30000, :message => \' is a bit long...\'}
  validates :body, :length =>         


        

Answer 1

presence: true already does that according to http://guides.rubyonrails.org/active_record_validations.html#presence

This helper validates that the specified attributes are not empty. It uses the blank? method to check if the value is either nil or a blank string, that is, a string that is either empty or consists of whitespace.
