铁路局:无限定方法名称 Array:0xb6c971cc
原标题:Ruby for Rails: underfined method name for #<Array:0xb6c971cc>

我在从表上发现一栏名字后,想显示一栏。

在我的测试.rb中,我界定了“联系人:姓名”;

在名录/控制器/测验/控制器/测验/控制器/控制器/控制器/控制器/控制器/控制器程序索引中,

def index
###[Ignore some code]
@mytesttbl=@user.find_by_id 
### I am able to verify the tuples in @mytesttbl
end 

In the view/mytest/index. rhtml

<div id="mytesttable"> <%= render(:partial =>"mytesttbl", :object => @mytesttbl)%> </div> 

In the /view/mytest/_mytesttbl.html.erb. 我有这样的守则。

<tr>
 <td><%=mytestbl.name %></td>
<tr>

当我持上述法典时,我就错过了——mytesttbl.html.erb。

undefined method  name   for #<Array:0xb6c971cc>

请提供帮助。 感谢

最佳回答

我猜测,这不是你的实际守则,因为它实际上没有工作。 页: 1 你们要么希望穿透阵列,要么如果你知道它只包含一个物体(如你实际上用一种独一无二的假体找到的),那么你就只能做<条码>。

www.un.org/spanish/ga/president 更改<代码>view/mytest/index.rhtml

<% @mytesttbl.each do |obj| %>
  <div id="mytesttable">
   <%= render(:partial =>"mytesttbl", :object => obj)%>
  </div>
<% end %>

Edit: also, view/mytest/_mytesttbl.html.erb

<tr>
 <td><%= object.name %></td>
<tr>

是否有人找不到@user.find_by_id? 通常在想获得姓名时:

controller @user= User.find(params[:id]) to find a user by a specific id.

意见

如果你想找到所有用户,

controller @user = User.find(:all)

意见

用户,由于用户在违约后发现有id,因此被定义为 red。
