Rails 4：編輯/更新線程，編輯/更新文章

Question

在我開始之前是的我知道我需要在帖子和線程控制器中的編輯和更新功能，但是我遇到的問題是forum_post.user的細節迷失了更新和線程在更新後複製帖子，所以我完全刪除了代碼，以便通過發佈控制器本身來解決問題。

但是，在發佈之前，您將需要路由/ forum /僅僅是一個將forum_threads/posts嵌入到其中並且不存在於其作用域之外的假路由。

途徑：

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 

論壇主題控制器

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 

論壇帖子控制器

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的論壇編輯路徑將是edit_forum_thread_path或只是糾正我，如果我錯了，但它的職位編輯/刪除路徑我需要幫助，因爲該控制器嵌套在forum_threads和使用模塊forum_threads，我原本認爲這將是edit_forum_threads_forum_posts_path，但這不是我最後一次嘗試之前刪除這些功能。

這將是edit_forum_thread_forum_post_path根據您的rake routes輸出。
