Heroku上的Rails 3.1.3 :(沒有路由匹配[GET]「/assets/rails.png」）

我在Heroku上安裝了幾個基本的應用程序，沒有問題，而且這個（Rails 3.1.3）看起來很好因爲它顯示的Rails歡迎頁面Heroku上的Rails 3.1.3 :(沒有路由匹配[GET]「/assets/rails.png」）

public/index.html.erb

但是當我刪除的頁面，然後設置

root :to => 'users#index'

我有一個問題。在heroku日誌中表示存在路由錯誤

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

有沒有人知道這是關於什麼的？

它看起來像你可能沒有預編譯你的資產，你被推到Heroku的前，嘗試：

rake assets:precompile 
git add . 
etc etc

我覺得應該幫助。欲瞭解更多信息，請參見這裏：http://devcenter.heroku.com/articles/rails31_heroku_cedar

你是對的，我沒有，我會做，但爲什麼Rails歡迎頁面工作？ – Leahcim 2012-01-14 22:14:41

它的工作原理是，歡迎頁面沒有必要的資源。所有樣式都包含在public/index.html文件中，並且不需要任何JavaScript或圖像。很高興我能幫上忙！ – 2012-01-14 22:18:21

簡單，它不是資產，它是視圖。 – Hauleth 2012-01-14 22:22:10

無需預編譯和雜波你混帳！

的Heroku將預編譯的資產

與軌道3.1.X你加入這application.rb中

config.assets.initialize_on_precompile = false

UPDATE 16 july2012

也軌3.2.x中

i t似乎是ActiveRecord和database.yml的問題！如果您不使用常規數據庫，但使用MongoDB，則不需要上述內容。但是，如果這樣做，則需要禁用initilize，因爲activerecord在初始化時讀取數據庫表，但數據庫在heroku的預編譯階段不可用。

與MongoDB沒有必要。

/UPDATE

軌3.2.x中 ：看一看application.rb中的頂部。 OMA的意見是我的，增加了透明度

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

我正在運行的Rails 3.2.6的一切更新，我不得不預編譯，否則rails.png不顯示。我正在關注Rails教程在線書籍。 – tentimes 2012-06-17 14:18:09

當然......希望在我嘗試過傑西的回答之前，我已經讀過了。簡單的預編譯並沒有幫助。而且...現在我的git回購臃腫。 – 2013-04-15 12:39:21

偷懶開始用薄（在Heroku）正與導軌3.2.3我不得不這樣做：

在配置/ application.rb中：

if defined?(Bundler) 
    # If you precompile assets before deploying to production, use this line 
    # Bundler.require(*Rails.groups(:assets => %w(development test))) 
    # If you want your assets lazily compiled in production, use this line 
    Bundler.require(:default, :assets, Rails.env) 
end 

... 


module Romulo 
    class Application < Rails::Application 

... 

    # Enable the asset pipeline 
    config.assets.enabled = true 

    # Version of your assets, change this if you want to expire all your assets 
    config.assets.version = '1.0' 

    # get precompilation working on heroku: 
    config.assets.initialize_on_precompile = true 

    config.serve_static_assets = false 
    end 
end

在配置/環境/ production.rb：

# Compress JavaScripts and CSS 
config.assets.compress = true 

# Don't fallback to assets pipeline if a precompiled asset is missed 
config.assets.compile = true 

# Generate digests for assets URLs 
config.assets.digest = true

無需預編譯的資產。
