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

What if you try adding something like this:

validates_format_of :body, :with => /\A[[:graph:]]\Z/i

Notes:

• validates_format_of lets you validate with regex
• [[:graph:]] lets you check a string for printable characters (see "Character Classes")
