You can call several times

szeryf · May 31, 20092 thanks

You can call it several times, like:

class Comment < ActiveRecord::Base
validate :must_be_friends
validate :must_be_awesome
...

or with several arguments:

class Comment < ActiveRecord::Base
validate :must_be_friends, :must_be_awesome
...

You can call it with an { :on => ~~~ } as the last argument

For example: validate :must_be_friends, :on => :create
