#validates(*params, &block) ⇒ Object

Syntactic sugar.

Example:

validates { presence_of :example, :if => :reading? }
  # => validate_presence_of :example, :if => :reading?
validates(:name) { presence and length :minimum => 6 }
  # => validates_presence_of :name
       validates_length_of :name, :minimum => 6
validates(:temp, :if => water?) { value :lt => 100 }
  # => validates_value_of :temp, :lt => 100, :if => water?

def validates(*params, &block)
  ValidationDelegator.new(self, *params).instance_eval(&block)
end

#validates_each(*attributes, &block) ⇒ Object
