Question

我在rails控制器中遇到问题，我的索引，显示页面不会出现在我的服务器中，这是我在控制器中的代码：

 class GamesController < ApplicationController

      def index
        @games=Game.all

        @render_carousel = true
      end

      def new
        @game=Game.new

      end

      def create
        @game=Game.new(game_params)
        if @game.save
          flash[:notice] = 'game created'
          redirect_to games_path
        else
          render 'new'
        end
      end

      def edit
        @game=Game.find(params[:id])
      end

      def update
        @game=Game.find(params[:id])
        if @game.update(game_params)
          flash[:notice] = 'game updated'
          redirect_to games_path
        else
          render 'edit'
        end
      end

      def destroy
        @game=Game.find(params[:id])
        @game.destroy(game_params)
          flash[:notice] = 'game deleted'
          redirect_to games_path
      end

      def show
        @game=Game.find(params[:id])
      end
      private

      def game_params
        params.require(:game).permit(:name, :year, :description, :price, :category_id, :creator_id,:coverpath)
      end
    end

这是我的索引页面代码：我在link_to行中收到错误，错误在索引和显示页面中

<div id="page-index">
     <div class="row">
       <div class="col-md-3 col-sm-3">
         <div class="thumbnail">
           <%= image_tag('cover/un1.jpg')%>
            <h4><b>Uncharted</b></h4>
            <p>The Uncharted series is one of the best action adventure franchises in recent gaming history,
              </p>
            <%= link_to 'Read More' ,@game_path(game), class:'btn btn-primary'%>
        <div>
      </div>
    </div>
</div>

Answer 1

这样做：

<%= link_to 'Read More', game_path(game), class:'btn btn-primary'%>

或者，就是这样：

<%= link_to 'Read More', game, class: 'btn btn-primary'%>

只要game实际存在于数据库中，两者都应该有效。

更新

循环浏览@games并显示index.html.erb文件中的每个游戏链接：

<% @games.each do |game| %>
  <%= link_to 'Read More', game_path(game), class:'btn btn-primary'%>
<% end %>
