Question

我做错了什么。

我什么都没改变，但现在是2011年，这个电话不像以前那样有效。

使用Active Resource，我可以进行以下调用：

>> Member.find(:all, :params => {:code => "1stb48024957856464d436e79ad9d7bc0c2d46d5a02"})
GET http://localhost:3000/members.xml?code=1stb48024957856464d436e79ad9d7bc0c2d46d5a02
--> 500 Internal Server Error  (1601 371ms)
ActiveResource::ServerError: Failed with 500 Internal Server Error

如您所见，我收到500错误。所以我去我的服务器，我正在打电话。

代码在控制器中：

def index
  @store = Store.first
  @members = @store.members.find_by_code(params[:code])

  respond_to do |format|
    format.html # index.html.erb
    format.xml  { render @members.to_xml } # i also tried :xml => @members but that screws up too the same way.
  end
end

但下面是堆栈跟踪。它正在解释为什么这只是停止工作。

任何想法都表示赞赏。我以为xml格式是免于渲染？何塞在lighthouse ticket中说了很多，但我找不到他在说什么。

更新：

作为服务器工作的Andy似乎正在发送200，所以谢谢，但现在我收到了这个错误：

Member.find(:all, :params => {:code => "1stb48024957856464d436e79ad9d7bc0c2d46d5a02"})

思考？它应该只是一个阵列回来，即使它是一个记录？

Answer 1

render :xml => @members是要走的路。

确保在生产中进行此更改后重新加载/重新启动服务器。

rails 3.0.1中需要xml格式???答案应该是NO
