將評論導入儀表板導軌

Question

嘿，我正在用rails創建一個博客，我的第一個應用程序。我正在嘗試通過儀表板首先批准評論。這是我目前的代碼。

的帖子控制器

class PostsController < ApplicationController 

    before_filter :authorize, only: [:edit, :update, :destroy, :create, :new] 

    def index 
     @posts = Post.where(:state => "published").order("created_at DESC") 
    end 

    def new 
     @post = Post.new 
    end 

    def show 
     @post = Post.find(params[:id]) 
     redirect_to_good_slug(@post) and return if bad_slug?(@post) 
    end 

    def create 
     @post = Post.new(post_params) 

     if @post.save 
      redirect_to dashboard_path 
     else 
      render 'new' 
     end 
    end 

    def edit 
     @post = Post.find(params[:id]) 
    end 

    def update 
     @post = Post.find(params[:id]) 
     if @post.update(params[:post].permit(:title, :text, :author, :short, :photo, :state)) 
      redirect_to dashboard_path 
     else 
      render 'edit' 
     end 
    end 

    def destroy 
     @post = Post.find(params[:id]) 
     @post.destroy 

     redirect_to dashboard_path 
    end 

    private 
     def post_params 
     params.require(:post).permit(:title, :text, :author, :short, :photo, :state) 
     end 
end 

儀表板控制器

class DashboardController < ApplicationController 

before_filter :authorize, only: [:index] 

def index 
    @posts = Post.order("created_at DESC") 
end 

end 

的意見控制器

class CommentsController < ApplicationController 

before_filter :authorize, only: [:destroy] 

def create 
    @post = Post.find(params[:post_id]) 
    @comment = 
    @post.comments.create(comments_params) 
    redirect_to post_path(@post) 
end 

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

private 
    def comments_params 
     params.require(:comment).permit(:commenter, :body) 
    end 
end 

註釋型號

class Comment < ActiveRecord::Base 
belongs_to :post 
end 

條

終於路線

resources :dashboard 
resources :posts do 
    resources :comments 
end 

再次，我非常新的後臺開發和紅寶石，所以如果需要的話我可以提供更多的信息。我想如果我可以把所有的意見都放到儀表板中，我就可以找出其他問題。

謝謝！

您將需要創建一個Dashboard控制器，允許有權訪問的用戶可以訪問該控制器。對於index操作，您可以執行類似操作。

def index 
    @posts = Post.find(approved: false) 
end 

您還可以將範圍添加到Post模型

class Post < ActiveRecord::Base 
    scope :approved, -> {where(approved: false)} 
end 

然後你可以只是做

def index 
    @posts = Post.approved 
end
