Rails 3的简单形式的错误：无法解析YAML

我new.html.erb：Rails 3的简单形式的错误：无法解析YAML

<h1>New konkurrancer</h1> 

    <%= simple_form_for [:admin, @konkurrancer] do |f| % 
     <%= f.input :name %> 
     <%= f.button :submit %> 
    <% end %> 


    <%= link_to 'Back', admin_konkurrancers_path %>

和我观点得到这个错误（http：//本地主机：3000 /管理/ konkurrancers /新）：

Psych::SyntaxError in Admin/konkurrancers#new 

Showing C:/Rails/konkurranceportalen/app/views/admin/konkurrancers/new.html.erb where line #4 raised:

可以运行'耙routes'和粘贴在这里输出？我认为问题在于ruby假设复数konkurrancer与konkurrancers有所不同 – Augusto 2011-03-09 13:24:00

我现在已经发布了路线 – 2011-03-09 13:46:51

尝试

<%= simple_form_for ['admin', @konkurrancer] do |f| %>

它看起来像你的名字间隔模式是？

是的我有一个名字空间模型。我得到以下错误无法解析YAML在第20行第14列提取的源代码（在第5行左右）： – 2011-03-09 13:39:29

我们需要查看yml文件，该问题正在报告中 – 2011-03-09 13:53:09

您的意思是语言区域设置文件？ – 2011-03-09 14:02:32

您正在使用名称空间模型 - 您必须在表单路径中引用名称空间。

试试这个：

<%= simple_form_for [:admin, @konkurrancer] do |f| %>
