的routes.rb

resources :posts do
  member do
    put "soft_destroy"
  end

  resources :comments do
    member do
      get "reply"
      post "create_reply"
      put "soft_destroy"
    end
  end
end

评论控制器

def destroy
  @post = Post.find(params[:post_id])
  @comment = Comment.find(params[:id])
  @comment.destroy
  redirect_to @post
end

删除视图文件上的链接

= link_to "delete", [@post, comment], method: :DELETE, remote: true

发布模型

has_many :comments, dependent: :destroy
accepts_nested_attributes_for :comments

评论模型

belongs_to :post

DELETE html谓词在帖子控制器上传播是否有原因？而不是仅仅调用show动作？

Answer 1

问题是由视图文件上的删除链接引起的

= link_to "delete", [@post, comment], method: :DELETE, remote: true

出于某种原因，使用方法DELETE的ajax请求似乎传播超出第一个DELETE请求。

我删除了remote: true，它现在向帖子发出GET请求而不是DELETE请求。

= link_to "delete", [@post, comment], method: :DELETE

我仍然不明白为什么会发生这种情况。

redirect_to方法在嵌套路由中传播DELETE http动作
