Heroku上的ActiveAdmin - 路由不正常

Question

這真令人沮喪。 AA過去對我來說效果很好，我想我已經嘗試了幾乎所有的東西。這是我的問題：

在本地主機上，一切工作正常，但一旦我在Heroku，奇怪的事情發生。

我的儀表板有[Badge]和[Student]等等。

我可以通過/admin/badges查看所有徽章。但是，一旦我做了編輯/視圖/顯示，Heroku上出現錯誤，而它在本地主機上正常工作。

在檢查，發生這種情況：

ActionView::Template::Error (No route matches {:action=>"edit", :controller=>"admin/students", :id=>#<Student id: nil, email: "", encrypted_password: "", password_salt: "", reset_password_token: nil, remember_token: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, avatar_file_name: nil, avatar_content_type: nil, avatar_file_size: nil, name: nil, role: nil, school: nil, parent_tutor_email: nil, parent_tutor_token: nil, pending_badge: nil, proficiency: 0.0, created_at: nil, account_type: "free", chargify_id: nil, fb_id: nil, score: 0, level_id: nil, special_bonuses: nil, birthday: nil, edu_level: nil>}): 

1: render renderer_for(:show) 

似乎:id應該是徽章ID，但它得到由學生對象，裏面是空的慘敗了。

這是我的route.rb文件：

WitsApp::Application.routes.draw do 

    ActiveAdmin.routes(self)  
    devise_for :admin_users, ActiveAdmin::Devise.config 


    devise_for :students, :controllers => {:registrations => "registrations", :sessions => "students_sessions", :passwords =>"devise/passwords"} do 
    match 'students/sign_up'    => 'registrations#create',  :as => "student_sign_up" 
    get 'students/sign_out'    => 'students_sessions#destroy' 
    get 'students/sign_in'    => 'pages#welcome' 
    get 'students/password/new'   => 'devise/passwords#new' 
    get 'students/password/edit'  => 'devise/passwords#edit' 
    post 'students/password'    => 'devise/passwords#create' 
    put 'students/password'    => 'devise/passwords#update' 

    get 'students', :to => 'students#show', :as => :student_root 
    resources :badges 
    resources :students 
    end 

    match '/sign_up' => 'pages#welcome', :as => "sign_up" 

    root :to => "pages#home" 
end 

這裏是耙路線（截），如果有幫助：

人有什麼想法？感謝您花時間！

拉了很多頭髮後，我發現問題和解決方案。

原因是因爲我在ApplicationHelper中覆蓋了def resource，並且總是返回Student。因此，我不得不重寫def resource，使得它看起來像：

def resource 
    @resource = Badge.find_by_id(params[:id]) || Badge.new 
end 

所有的一切都將重新工作。我只是不確定它爲什麼沒有早點失敗。 :(
