For example: class Person include DataMapper::Resource
property :id, Integer, :serial => true property :first_name, String, :nullable => false property :last_name, String has n :posts end class Post include DataMapper::Resource property :id, Integer, :serial => true property :title, String, :nullable => false property :body, Text belongs_to :author, :class_name => "Person" end What would be the best way to validate the presence of an author when a post is saved? I noticed that the documentation says that some validations are automatically inferred (e.g., if :nullable => false or :length is specified). Is there any way to include this validation in the belongs_to method call? If not, what would anyone suggest?
