#active ⇒ Object

Always have Model.active available. It is a good practice to use it when you want the active records. Even use it when no logic is in place yet. Now it is an alias for scoped, but can be overwritten for custom behaviour, for example: class Post < ActiveRecord::Base delete_softly has_many :comments def self.active super.where(:disabled.ne => true) end end class Comment < ActiveRecord::Base belongs_to :post end will result in: Post.all #=> SELECT * FROM posts WHERE deleted_at IS NULL; Post.active #=> SELECT * FROM posts WHERE deleted_at IS NULL AND disabled != 't'; Comment.all #=> SELECT * FROM comments; Comment.active #=> SELECT * FROM comments;

#delete_softly(options = {:enforce => :active}) ⇒ Object

Make the model delete softly. A deleted_at:datetime column is required for this to work. The two most important differences are that it can be enforce on a model or be more free. class Post < ActiveRecord::Base delete_softly end will enforce soft delete on the post model. A deleted post will never appear, unless the explicit with_deleted is called. When the model is: class Post < ActiveRecord::Base delete_softly :enforce => false end An object will still be available after destroy is called,
