Question

嘿我正在使用rails创建一个博客，这是我的第一个应用。我正在尝试通过仪表板进行必须首先批准的评论。这是我目前的代码。

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

仪表板控制器

class DashboardController < ApplicationController

before_filter :authorize, only: [:index]

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

end

评论控制器

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

评论模型

class Comment < ActiveRecord::Base
 belongs_to :post
end

最后是路线

 resources :dashboard
 resources :posts do
  resources :comments
 end

再一次，我对后端dev和ruby很新，所以如果需要我可以提供更多信息。我想如果我能把所有评论都放到仪表板上，我就可以把剩余的评论搞清楚了。

谢谢！

您需要创建一个Dashboard控制器，具有访问权限的用户可以访问该控制器。对于index操作，您可以执行类似的操作。

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

您还可以将范围添加到Post模型

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

然后你可以做

def index
  @posts = Post.approved
end
