Instance Method Details

#ancestors ⇒ Object

Retrieves all of the parents of the instance. (Think of it including grandparents as well.)

Example

If you had three records in a structure similar to this:

#<Comment id: 1, parent_id: nil>
  #<Comment id: 2, parent_id: 1>
    #<Comment id: 3, parent_id: 2>

You would do the following to return all ancestors

comment_3.ancestors # => [#<Comment id: 2, parent_id: 1>, #<Comment id: 1, parent_id: nil>]
