我找不到问题的根源。
我正在使用 Rails 3.1.1 和 ActiveAdmin 0.4.0。Web 服务器是 WEBrick 1.3.1。
每个请求，ActiveAdmin 文件都显示在日志中。例如：
Started GET "/admin/" for 127.0.0.1 at 2012-04-17 21:28:37 +0200
[nil, ["path/to/the/app/admin", "path/to/the/app/admin/modela.rb", "path/to/the/app/admin/modelb.rb", "path/to/the/app/admin/modelc.rb", "path/to/the/app/admin/modeld.rb", "path/to/the/app/admin/modele.rb", "path/to/the/app/admin/modelf.rb", "path/to/the/app/admin/modelg.rb", "path/to/the/app/admin/modelh.rb", "path/to/the/app/admin/modeli.rb"]]
Processing by Admin::DashboardController#index as HTML
Completed 401 Unauthorized in 7ms
app/admin/dashboards.rb：
ActiveAdmin::Dashboards.build do
end
无论页面如何，ActiveAdmin 文件都会显示在日志中……无论环境如何（开发、登台、生产……）
另一个页面，另一个例子：
[...]

看，在每个请求中都有：
[nil, ["path/to/the/app/admin", "path/to/the/app/admin/modela.rb", "path/to/the/app/admin/modelb.rb", "path/to/the/app/admin/modelc.rb", "path/to/the/app/admin/modeld.rb", "path/to/the/app/admin/modele.rb", "path/to/the/app/admin/modelf.rb", "path/to/the/app/admin/modelg.rb", "path/to/the/app/admin/modelh.rb", "path/to/the/app/admin/modeli.rb"]]
有任何想法吗？
