重新加载 rvm 3.0.0 重新安装包，现在在操作视图中获取未定义的方法：模板

如何解决重新加载 rvm 3.0.0 重新安装包，现在在操作视图中获取未定义的方法：模板

背景：我正在尝试生成一个用户引导列表，其中允许用户进行两个选择（商店和买家）。保存列表的表没有购买者的名字，但有指向商店的 store_id。买家的名字是从第三张表中得出的。

在我不得不从 rvm 卸载 rails-3.0.0 之前，这段代码运行良好。重新安装并执行 bundle install 后，这个 simple_form form-inline 代码开始抛出以下日志中显示的错误：

在 list.html.erb 文件中工作的代码：

<%= simple_form_for :search,url: list_path,method: "GET",html: { class: 'form-inline' } do |f| %><br>
    <%= f.input :id,collection: @stores,label: false  %></td><br>
    <td><br>
    <%= f.collection_select :buyer,@buyers,:buyer,include_blank: true %><br>
    </td><td>
     <%= f.submit "Submit",class: "btn btn-primary" %><br>
<% end %>
</td>
</tr></table>

数组@store 和@buyer 是在 def list 节的 shop 控制器中生成的。此处显示：

  def list
      @search = params["search"]
      logger.debug "\n\n#{@search}.inspect\n\n"
      @lists = Shop.get_my_list(params["search"])
      
          @elists = Shop.find_by_sql("select distinct S.vendor,S.item,S.cnt,S.coupon from SHOPS AS S left join MUPCs as M on m.item = s.item WHERE M.ID IS NULL")

          @buyers = Shop.find_by_sql("select distinct buyer,buyer from mupcs")

  end

日志生成：

解决方法

找到了解决办法。我不得不创建一个新的私人白名单并将内联名称从“搜索”更改为“genlist”，但现在它似乎可以工作了。
