我的模型类是:
class Category < ActiveRecord::Base
acts_as_nested_set
has_many :children, :foreign_key => "parent_id", :class_name => 'Category'
belongs_to :parent, :foreign_key => "parent_id", :class_name => 'Category'
def to_param
slug
end
end
是否可能有这样的递归路由,例如:
/root_category_slug/child_category_slug/child_of_a_child_category_slug
... 以此类推
感谢任何帮助 :)
