ruby-on-rails - Heroku 上的 Rails 3.1.3 : (No route matches [GET] "/assets/rails.png")

我已经在 Heroku 上安装了一些基本的应用程序，没有问题，这个(Rails 3.1.3)看起来不错，因为它显示了 Rails 欢迎页面

public/index.html.erb

但是当我删除该页面然后设置 
root :to => 'users#index'

我有问题。在 heroku 日志中，它说存在路由错误 
ActionController::RoutingError (No route matches [GET] "/assets/rails.png"):

有谁知道这是关于什么的？

最佳答案

无需预编译 把你的 git 弄得一团糟!

heroku 将预编译您的 Assets

带 rails 3.1.x 您将此添加到 application.rb

config.assets.initialize_on_precompile = false

2012 年 7 月 16 日更新

还有 rails 3.2.x

ActiveRecord 和 database.yml 似乎有问题!如果您不使用常规数据库，而是使用 MongoDB，则不需要上述内容。但是，如果这样做，则需要禁用初始化，因为 activerecord 在初始化时读取数据库表，但数据库在 heroku 的预编译阶段不可用。

与 MongoDB 没有必要 .

/更新

rails 3.2.x
: 看顶部 application.rb . OMA 评论是我的，为清楚起见添加 
if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  "OMA - comment this line"
  #Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  "OMA - uncomment this line"
  Bundler.require(:default, :assets, Rails.env)
end
