[英]Ruby on Rails Application Page Does Not Exist in Heroku Production Environment
在localhost
上进行测试时,在我的应用程序中,我可以单击一个链接,将我带到edit_event_path(event)
页面,它可以正常运行。
当我将其推送到Heroku时,我不断收到错误消息“此页面不存在”,但是我仍然能够访问/event
索引页面。
它似乎仅用于编辑页面。
我的routes.rb
Rails.application.routes.draw do
resources :approvals
devise_for :users
resources :events
resources :roles
# The priority is based upon order of creation: first created -> highest priority.
# See how all your routes lay out with "rake routes".
scope "/admin" do
resources :users do
collection do
match 'update_collection', via: [:put, :patch]
end
end
end
# You can have the root of your site routed with "root"
root 'events#index'
# Example of regular route:
# get 'products/:id' => 'catalog#view'
# Example of named route that can be invoked with purchase_url(id: product.id)
# get 'products/:id/purchase' => 'catalog#purchase', as: :purchase
# Example resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Example resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Example resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Example resource route with more complex sub-resources:
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', on: :collection
# end
# end
# Example resource route with concerns:
# concern :toggleable do
# post 'toggle'
# end
# resources :posts, concerns: :toggleable
# resources :photos, concerns: :toggleable
# Example resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
end

我不确定是否需要其他日志或其他日志来回答我的问题,但是如果您发表评论,我会提供它们! 谢谢!
您的代码看起来不错-可能没有ID为1的Event
。您可能尚未在生产中创建任何Event
,或者您已经删除了它。 /events/1
也可能会是404。
转到/events/new
创建一个Event
。 您也可以登录到您的Heroku数据库heroku pg:psql
(假设你有工具区安装)和SELECT id FROM events
,以验证其ID是否存在。
您还使用params[:id]
加载@user
,这是Event
的ID。 如果不存在与Event
具有相同ID的User
,Rails会引发相同的RecordNotFound
异常,这是作为404返回的。看起来您已经在该应用程序上登录了,所以您可能想要通过Devise从session[:user_id]
加载,否则您将建立身份验证。
