Rails 4：编辑/更新线程，编辑/更新文章

Question

在我开始之前是的我知道我需要在帖子和线程控制器中的编辑和更新功能，但是我遇到的问题是forum_post.user的细节迷失了更新和线程在更新后复制帖子，所以我完全删除了代码，以便通过发布控制器本身来解决问题。

但是，在发布之前，您将需要路由/ forum /仅仅是一个将forum_threads/posts嵌入到其中并且不存在于其作用域之外的假路由。

         root GET /                 forum_threads#index 

途径：

Rails.application.routes.draw do 
devise_for :users 
    scope "/forum" do 
     resources :forum_threads do 
       resources :forum_posts, module: :forum_threads 
     end 
    end 

    resources :users do 
    collection do 
     post :import 
    end 
    end 
root 'forum_threads#index' 
end 

论坛主题控制器

class ForumThreadsController < ApplicationController 
    before_action :authenticate_user!, except: [:index, :show] 
    before_action :set_forum_thread, except: [:index, :new, :create] 

    def index 
    @q = ForumThread.search(params[:q]) 
    @forum_threads = @q.result(distinct: true) 
    end 

    def show 
    @forum_post = ForumPost.new 
    end 

    def new 
    @forum_thread = ForumThread.new 
    @forum_thread.forum_posts.new 
    end 

    def create 
    @forum_thread = current_user.forum_threads.new forum_thread_params 
    @forum_thread.forum_posts.first.user_id = current_user.id 

    if @forum_thread.save 
     redirect_to @forum_thread 
    else 
     render action: :new 
    end 
    end 

    def destroy 
    @forum_thread.destroy 
    redirect_to root_path 
    end 

    private 

    def set_forum_thread 
     @forum_thread = ForumThread.find(params[:id]) 
    end 

    def forum_thread_params 
     params.require(:forum_thread).permit(:subject, forum_posts_attributes: [:body]) 
    end 
end 

论坛帖子控制器

class ForumThreads::ForumPostsController < ApplicationController 
    before_action :authenticate_user! 
    before_action :set_forum_thread 

    def create 
    @forum_post = @forum_thread.forum_posts.new forum_post_params 
    @forum_post.user = current_user 

    if @forum_post.save 
     redirect_to forum_thread_path(@forum_thread, anchor: "forum_post_#{@forum_post.id}"), notice: "Successfully posted!" 
    else 
     redirect_to @forum_thread, alert: "Unable to save your post" 
    end 
    end 

    private 

    def set_forum_thread 
     @forum_thread = ForumThread.find(params[:forum_thread_id]) 
    end 

    def forum_post_params 
     params.require(:forum_post).permit(:body) 
    end 
end 

我知道link_to的论坛编辑路径将是edit_forum_thread_path或只是纠正我，如果我错了，但它的职位编辑/删除路径我需要帮助，因为该控制器嵌套在forum_threads和使用模块forum_threads，我原本认为这将是edit_forum_threads_forum_posts_path，但这不是我最后一次尝试之前删除这些功能。

Answer 1

这将是edit_forum_thread_forum_post_path根据您的rake routes输出。
