Rails 4，Heroku不能识别预编译的清单 - （指纹）.json [英] Rails 4, Heroku doesn't recognize precompiled manifest-(fingerprint).json

问题描述

升级到Rails 4后，public / assets / manifest.yml不再生成。而是存在不同的格式化的清单 - （指纹）.json。
但在我看来，服务器仍在寻找旧的manifest.yml格式，忽略.json版本？

我看到其他问题基于类似的问题，但他们似乎被升级到Rails 4，将rails_12factor添加到gem文件，设置serve_static_assets = true等等，但这些解决方案似乎没有任何影响，在我的情况。

由于这个令人讨厌的问题，我感到很累，并且没有受到鼓舞，任何帮助都将不胜感激！

Heroku的日志文件：

  ActionController :: RoutingError（没有路由匹配[GET]/assets/layouts/test/test.html）：
  

Gemfile：

  ruby​​' 2.0.0'
 gem'rails'，'4.0.0'
 ... 
 gemcompass-rails，github：milgner / compass-rails，ref：1749c06f15dc4b058427e7969810457213647fb8 
 ... 
 gem'rails_12factor'，group：：production 
  

production.rb

  RailsFoundationAngular :: Application.configure do 
 config.assets.initialize_on_precompile = false 
 config.cache_classes = true 
 config.consider_all_requests_local = false 
 config.action_controller.perform_caching = true 
 config.serve_static_assets = true 
 config.assets.compress = true 
 config.assets.compile = false 
 config.assets。 digest = true 
 config.i18n.fallbacks = true 
 config.active_support.deprecation =：notify 
 config.action_dispatch.x_sendfile_header = nil 
 end 
  

我使用的是Angular和他们的ui-router，这是我的routes.js.coffee中test.html链接的部分：

  .stateroot，
 url：/
 views：
 root：
 controller：ApplicationController
 templateUrl：/assets/layouts/test/test.html
  

我也尝试过预编译loc盟友，但因为我在这里也使用Rails 4，所以仍然没有创建manifest.yml，只有.json版本。
当然，在开发过程中所有的工作都是完美的......

所以我的实际提示：
我让Heroku识别并使用manifest-（fingerprint）.json -file或其他方法来实现这个功能？

解决方案

答案是，Heroku已经识别并使用了清单（指纹）.json文件。在我上面评论中的解决方法是引用这些文件的正确方法，通过这样做，清单文件就可以被使用。

重命名带有.erb内部链接的文件，并像这样引用： templateUrl：<％= asset_path（'layouts / test / test.html'）％>就是这样做的。所有内部文件，图像和html文件应该像这样被引用。

这里所有的描述都非常透彻：资产管道指南

看起来很简单直接现在，但我真的花了很多时间试图从一开始就错误地解决这个问题。
我希望这个答案可以节省别人的时间。

After upgrading to Rails 4, public/assets/manifest.yml is not generated anymore. Instead the different formatted manifest-(fingerprint).json is present. But it seems to me that the server is still looking for the old manifest.yml format, ignoring the .json version?

I see other questions based on similar problems, but they seems to be sovled by upgrading to Rails 4, adding rails_12factor to gem file, setting serve_static_assets = true, etc., but none of these solutions seems to have any effect in my scenario.

I am tired and uninspired due to this annoying problem, any help will be appreciated!

Logfile from Heroku:

ActionController::RoutingError (No route matches [GET] "/assets/layouts/test/test.html"):

Gemfile:

ruby '2.0.0'
gem 'rails', '4.0.0'
...
gem "compass-rails", github: "milgner/compass-rails", ref: "1749c06f15dc4b058427e7969810457213647fb8"
...
gem 'rails_12factor', group: :production

production.rb

RailsFoundationAngular::Application.configure do
  config.assets.initialize_on_precompile = false
  config.cache_classes = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_assets = true
  config.assets.compress = true  
  config.assets.compile = false
  config.assets.digest = true
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.action_dispatch.x_sendfile_header = nil
end

I am using Angular and their ui-router, and this is the part of my routes.js.coffee where the test.html is linked:

    .state "root",
      url: "/"
      views:
        "root":
          controller: "ApplicationController"
          templateUrl: "/assets/layouts/test/test.html"

I have also tried precompiling locally, but as I am using Rails 4 here as well, still no manifest.yml is created, only the .json version. Of course, everything is working just perfectly in development...

So my actual cuestion: How do I make Heroku recognize and use the manifest-(fingerprint).json -file, or alternative ways to make this work?

解决方案

The answer is, that Heroku already does recognize and use the manifest-(fingerprint).json -file. The "workaround" in my comment above, is the proper way to reference these files, and by doing so, the manifest-file is used the way it's ment to be used.

Renaming the file with the internal link to .erb, and referencing like this: templateUrl: "<%= asset_path('layouts/test/test.html') %>" does the trick. All internal files, images, and html -files should be referenced like this.

It's all described very thoroughly here: Asset-pipeline guide

It seems so simple and straightforward now, but I really spent a lot of time trying to get the wrong way around this from the beginning. I hope this answer can save the time for someone else.
