我第一次在设计中使用Administrate，并且刚刚生成了一些设计控制器，以便自定义它们，现在Administrate抛出一个错误。
对于我生成的每个控制器，它抛出以下错误:
NameError - uninitialized constant AdminUsers::Session:

有人知道这个问题的解决方案是什么吗?
我在Rails 5.0.1上遇到过类似的administration和design问题。
事实证明，这是administrate@0.3.0关于名称空间处理的一个已知问题。
如果您不想等待带有修复的新版本，这里有一个解决方法可以避免此问题:
很简单。您所需要做的只是使用另一个名称空间，而不是以"admin"开头的字符串。例如，你可以像下面这样修改它，问题就会消失。
devise_for :admin_users, controllers: {
sessions: 'admeen_users/sessions',
...
}
class AdmeenUsers::SessionsController < Devise::SessionsController
...
end
注:如果你想用AdminUser模型认证管理，你需要用authenticate :admin_user do ... end来包装namespace :admin do ... end部分。
