Question

所以我想在我的网络应用程序中使用Devise，并且在localhost上测试的一切都很好，但当我将它上传到我的ec2实例时，我收到错误'没有路由匹配[GET]“/”'和我不知道怎么解决这个问题。

这是我的Routes.rb：

devise_for :users

resources :submissions

root to: 'home#index'

scope "api" do
get "/submissions(.:format)" => "submissions#index"
get "/submissions/:id(.:format)" => "submissions#show"
end

get "/submissions/:id/edit(.:format)" => "submissions#edit"

这是我的Gemfile，记住我确实尝试过只有gem：“设计”，但这也不起作用。

source 'https://rubygems.org'

gem 'rails', '3.2.13'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'

gem 'therubyracer'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
 gem 'sass-rails',   '~> 3.2.3'
 gem 'coffee-rails', '~> 3.2.1'

 # See https://github.com/sstephenson/execjs#readme for more supported runtimes
 # gem 'therubyracer', :platforms => :ruby

 gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

gem "devise", :git => "git://github.com/plataformatec/devise.git"

这是我的ec2实例上的routes.rb：

new_user_session GET    /users/sign_in(.:format)        devise/sessions#new
        user_session POST   /users/sign_in(.:format)        devise/sessions#create

                     DELETE /users(.:format)                devise/registrations#destroy
         submissions GET    /submissions(.:format)          submissions#index
                     POST   /submissions(.:format)          submissions#create
      new_submission GET    /submissions/new(.:format)      submissions#new
     edit_submission GET    /submissions/:id/edit(.:format) submissions#edit
              submission GET    /submissions/:id(.:format)      submissions#show
                     PUT    /submissions/:id(.:format)      submissions#update
                     DELETE /submissions/:id(.:format)      submissions#destroy
                root        /                               home#index
                     GET    /api/submissions(.:format)      submissions#index
                     GET    /api/submissions/:id(.:format)  submissions#show
                     GET    /submissions/:id/edit(.:format) submissions#edit

Answer 1

您可以使用rake routes检查是否有此路线。

您是否已在生产模式下本地运行？

如果仍然无法解决此问题，您最好粘贴rake routes的结果，然后有人可能会弄明白。

Answer 2

在您的应用程序的根目录运行它，并检查它是否返回根路由。

rake routes | grep root

设计没有路线匹配[GET]“/”
