Heroku上的Rails 3.1.3 :(没有路由匹配[GET]"/assets/rails.png")

Question

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)似乎很好,因为它显示了Rails欢迎页面

public/index.html.erb

但当我删除该页面然后设置

root :to => 'users#index'

我遇到了问题.在heroku日志中,它表示存在路由错误

ActionController::RoutingError (No route matches [GET] "/assets/rails.png"):

有谁知道这是关于什么的？

Answer 1

不需要预先编译和混乱你的git!

heroku将预编译您的资产

使用rails 3.1.x,您将其添加到application.rb

config.assets.initialize_on_precompile = false

更新2012年7月16日

还有rails 3.2.x.

它似乎是ActiveRecord和database.yml的问题!如果您不使用常规数据库,但使用MongoDB,则不需要上述内容.但是,如果这样做,则需要禁用initilize,因为activerecord在初始化时读取数据库表,但在heroku的预编译阶段无法使用数据库.

使用MongoDB没有必要.

/ UPDATE

rails 3.2.x :查看application.rb的顶部.为了清楚起见,OMA评论是我的

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

Answer 2

看起来您在推送到Heroku之前可能没有对您的资产进行预编译,请尝试:

rake assets:precompile
git add .
etc etc

我认为这应该有所帮助.有关详细信息,请参阅此处:http://devcenter.heroku.com/articles/rails31_heroku_cedar
