我正在努力解决错误（Admin::AdminUsers#index 中的 NameError）

我正在使用设计和管理。我必须设计控制器，所以设置一个控制器选项。

我的路线文件在这里。

Rails.application.routes.draw do
  devise_for :admin_users, path: :admin, skip: [:registration], :controllers => {
    :sessions => 'admin_users/sessions'
  }
  namespace :admin do
    root to: "admin_users#index"
    resources :admin_users
  end
end

但是，设置 :controller 后，parameter,ameError in Admin::AdminUsers#index会在访问 admin/ 路径时发生。

错误详情： 

ActionView::Template::Error (uninitialized constant AdminUsers::Session):
10: <nav class="navigation" role="navigation">
11:   <% Administrate::Namespace.new(namespace).resources.each do |resource| %>
12:     <%= link_to(
13:       display_resource_name(resource),
14:       [namespace, resource_index_route_key(resource)],
15:       class: "navigation__link navigation__link--#{nav_link_state(resource)}"
16:     ) %>

复制程序：

・access to /admin (and login screen is shown)
・enter e-mail address and pass and submit
・Error occur (after login success)

你能告诉我错误发生的原因吗？

在设置控制器参数之前，它工作正常。

Rails.application.routes.draw do
  devise_for :admin_users, path: :admin, skip: [:registration]
  namespace :admin do
    root to: "admin_users#index"
    resources :admin_users
  end
end

rake 路线相同

从我看到的你正在设置 :sessions => 'admin_users/sessions的情况来看，我没有看到任何与你设置的路线相匹配的路线。

我看到一条带有会话的路线正在跟踪

    new_admin_user_session GET    /admin/sign_in(.:format)              devise/sessions#new
        admin_user_session POST   /admin/sign_in(.:format)              devise/sessions#create
destroy_admin_user_session DELETE /admin/sign_out(.:format)             devise/sessions#destroy

我认为您要添加devise/sessions，否则您必须创建一条与您的路线相匹配的路线admin_users/sessions
