Rails/Heroku 您要查找的页面不存在答案

【问题标题】：Rails/Heroku The page you were looking for doesn't existRails/Heroku 您要查找的页面不存在
【发布时间】：2014-06-01 17:26:22
【问题描述】：

我从 Heroku 收到“您要查找的页面不存在”错误。应用程序在开发和生产中运行良好，但在 Heroku 上没有。

“heroku 日志”表明 ActionController::RoutingError (No route matches [GET] "/"): 存在路由问题.

config/routes.rb

    Foodsterbater::Application.routes.draw do
      get "/welcome/index"
      get "static_pages/home"
      get "static_pages/about"
      get "static_pages/contact"
      resources :gigs

      resources :users

      root 'welcome#index'
    end

【问题讨论】：

您是否使用 heroku rake db:migrate 运行过迁移？
在将 repo 推送到 Heroku 之前，您是否将路由提交到 repo？
我运行 rake db:migrate 以及 heroku 运行 rake db:migrate。一切都已提交并推送。

标签： ruby-on-rails heroku url-routing

【解决方案1】：

我遇到了类似的问题；但是，在更改位于 config/environments/production.rb 中的 production.rb 的 1 行代码后，

config.assets.compile = false
to

config.assets.compile = true

提交新的更改。

【讨论】：

这不是我的问题

【解决方案2】：

我个人会说这是你的错误：

#config/routes.rb
get "/welcome/index"

这究竟是为了达到什么目的？你要做的就是向一个不存在的控制器发送任何domain.com/welcome/index 的请求

我会把你的路线改成这样：

   #config/routes.rb
   Foodsterbater::Application.routes.draw do
      resources :gigs, :users
      resources :static_pages, only: [] do
           get :home
           get :about
           get :contact
      end
      root 'welcome#index'
    end

【讨论】：

这很有帮助。谢谢。
没问题！还有什么需要帮助的吗？

【解决方案3】：

我解决了这个问题，但我不确定如何解决。我按照上面的建议调整了路线，但我也犯了一些 git 错误。我以为我是在主分支工作，但我认为我是在一个分支工作，而不是在推送之前合并。重新阅读了一些 git 文档以弄清楚它。 http://git-scm.com/book/en/Git-Branching-Basic-Branching-and-Merging
