在 ActiveAdmin 0.4.3 和 Rails 3.2.2 中，我正在尝试自定义我的文章模式的显示屏幕

ActiveAdmin.register Article do

  show do
     render "show"
  end

end

在 app/views/admin/articles/_show.html.haml

%div= article.description

但是每当我尝试展示一篇文章时，我都会得到：

NoMethodError in Admin/articles#show

Showing /Users/phishman/Sites/wisegrowth/app/views/admin/articles/_show.html.haml where line #1 raised:

undefined method `description' for <article></article>
:Arbre::HTML::Article

Extracted source (around line #1):

1: %div= article.description

Trace of template inclusion: /Users/phishman/.rvm/gems/ruby-1.9.2-p290/gems/activeadmin-0.4.3/app/views/active_admin/resource/show.html.arb

app/admin/articles.rb:20:in `block (2 levels) in <top (required)>'
app/middleware/flash_session_cookie_middleware.rb:17:in `call'

你能帮我解决这个问题吗？这让我快疯了！

在控制台中，一切似乎都运行良好，如果我这样做：

a = Article.last
a.description
=> "my article description"

试试这个：

render :partial => "show", :locals => {:article => article }
