在Rails 4.0中，为删除操作创建link_to时出现问题 [英] Issue in rails 4.0 with creating a link_to for a delete action

问题描述

这是我在Rails中的第一个项目，它是创建一个表来存储有关游戏的数据。我可以显示表格中有关获胜者分数，失败者分数等的数据。但是，我的表格列存在问题，其中包含每个游戏的删除链接。

This is my first project in rails, which is to create a table that will store data about games. I'm able to display data from the table about winner score, loser score, etc. However, I have issues with my table column that contains delete links for each game.

这是我在游戏控制器中删除方法的代码：

Here's my code in the games controller for the delete method:

def delete
  @game = Game.find(params[:game])
  @game.destroy()
  redirect_to :action => 'index'
end

我的表代码的一个片段，其中包括link_to命令

A snippet of my table code, which includes the line for the link_to command

    <% @games_items.each do |t| %>
     <tr>
        <td><%= t.winner.name %></td>
        <td><%= t.loser.name %></td>
        <td><%= t.challenger.name %></td>
        <td><%= t.winner_score %></td>
        <td><%= t.loser_score %></td>
        <td><%= link_to 'Delete', delete_game_path(id: t.id)%></td>
     </tr>
    <% end %>

在路由文件中，我叫

resources :games

据我所知，这有助于产生基本路由。有人可以帮我弄清楚为什么我的link_to无法正常工作吗？

Which, to my knowledge, helps generate the base routing. Could anyone help me figure out why my link_to is not working?

推荐答案

如果使用（建议）资源：
a）删除记录的操作应命名为 destroy 。
b）使用：id 参数搜索游戏：

If you use (which is adviced) resources: a) Your action for deleting records should be named destroy. b) Game is searched for with :id parameter:

def destroy
  @game = Game.find(params[:id])
  @game.destroy
  redirect_to :action => 'index'
end

c）您的链接应为：

<%= link_to 'Delete', t, method: :delete %>

因为路径与显示操作，唯一更改的选项是HTTP方法。

since the path is the same as for the show action, the only thig that changes is HTTP method.
