acts_as_tree
|
||||
============
|
||||
|
||||
Specify this +acts_as+ extension if you want to model a tree structure by providing a parent association and a children
|
||||
association. This requires that you have a foreign key column, which by default is called +parent_id+.
|
||||
|
||||
class Category < ActiveRecord::Base
|
||||
acts_as_tree :order => "name"
|
||||
end
|
||||
|
||||
Example:
|
||||
root
|
||||
\_ child1
|
||||
\_ subchild1
|
||||
\_ subchild2
|
||||
|
||||
root = Category.create("name" => "root")
|
||||
child1 = root.children.create("name" => "child1")
|
||||
subchild1 = child1.children.create("name" => "subchild1")
|
||||
|
||||
root.parent # => nil
|
||||
child1.parent # => root
|
||||
root.children # => [child1]
|
||||
root.children.first.children.first # => subchild1
