我的问题就像这个线程的标题一样简单我有两个类

class Category < ActiveRecord::Base

  has_many :subcategories, dependent: :destroy

  accepts_nested_attributes_for :subcategories

end

class Subcategory < ActiveRecord::Base
  belongs_to :category
end

但是当我点击link_to "Delete", category_path(category), method: :delete请求的类别被破坏时，所有子类别都像什么都没发生一样。

您是在调用delete类别吗？你应该打电话destroy。
