我试图创建一个Sprocket指令来考虑我的配置文件中的更改：

在initializers / sprockets.rb中

class Sprockets::DirectiveProcessor
  def process_depend_on_config_directive(file)
    path = File.expand_path(file, "#{Rails.root}/config/locales")
    context.depend_on(path)
  end
end

在application.js中

//= depend_on_config en.yml
//= depend_on_config fr.yml

刷新有关js文件的页面给了我不同的答案,我无法修复此行为：

Edit2：添加更多信息：

更好的翻译服务文件(.erb)：

<% environment.context_class.instance_eval { include ApplicationHelper } %>
<%# encoding: utf-8 %>

app.factory('Pg', ['SETTINGS', function(SETTINGS) {
  var polyglot = {};

  polyglot.translations = {

    en: new Polyglot({ phrases: <%=  I18n.with_locale(:en) { phrases_for_polyglot.to_json } %>, locale: "en" }),
    fr: new Polyglot({ phrases: <%=  I18n.with_locale(:fr) { phrases_for_polyglot.to_json } %>, locale: "fr" })
  };

  polyglot.current = 'en';

  polyglot.t = _.memoize(function(key, opts) {
    return polyglot.translations[polyglot.current].t(key, opts);
  }, function(key, opts){
    if(opts===undefined){ return polyglot.current + ''+ key; }
    return polyglot.current + '' + key + polyglot.serialize(opts);
  });


  polyglot.serialize = function(obj) {

    var str = [];
    for(var p in obj){
      if(obj.hasOwnProperty(p)) {
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
      }
    }
    return str.join("&");
  };
  //fde


  polyglot.selectLanguage = function(lang){
    polyglot.current = lang;
  };

  return polyglot;
}]);

开发内容.rb：

  end

我正在使用rails 4.1.1.有什么建议？我可以根据需要提供更多信息.

尝试答案后更新：我在下面的答案后做了以下更改：

application.js => application.js.erb

<%= depend_on 'en.yml' %>
<%= depend_on 'fr.yml' %>
<% I18n.backend.send(:init_translations) unless I18n.backend.initialized? %>
console.log(<%= I18n.backend.send(:translations).to_json %>);
//= require angular-rails-templates
//= require honeybadger.min
//= require_tree ./dependencies
//= require lodash.min
//= require polyglot.min
//= require lunr.min
//= require angulartics.min
//= require angulartics-ga.min
//= require ./angular_js/fancyinput_library/ac-fancy-input
//= require angular-main
//= require_tree ./angular_js
//= require_tree ../templates

将以下内容添加到application.rb中

config.assets.paths<< Rails.root.join(‘config’,’locales’) 新开发.rb

# Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations
  # config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.

  config.assets.compile = true

  config.serve_static_assets = true
  config.assets.debug = false
  config.assets.digest = true

  # config.assets.configure do |env|
  #   env.cache = ActiveSupport::Cache.lookup_store(:null_store)
  # end
  # config.middleware.use Rack::Prerender
  config.root_url = 'lvh.me:5000'
  config.api_host = 'http://lvh.me:3000'

结果：js错误,app未加载.

JS错误：

浏览器中的js文件：

更新2：我几乎得到了它.我注意到我没有在正确的文件中包含depend_on方法.我将它们移动到相关的.js.erb并开始工作.我唯一剩下的问题是我必须刷新页面两次.我认为如果application.js保持不变,那就更好了. 🙂

最佳答案 这里有一些问题.

第一：

我相信你误解了rails默认情况下如何处理生产中的资产.

在生产中,资产将被预编译一次,就是这样.回到生产中的资产管道通常是不明智的,这就是为什么你在/config/environments/production.rb中看到这个：

# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = false

因此,您的Sprockets指令在生产中不会起作用 – 默认情况下是约定的;并且,有充分理由不让您的生产服务器回退到资产管道.

第二：

您不需要编写自己的DirectiveProcessor来完成您想要实现的目标.您需要做的就是将其添加到依赖文件的顶部(即：application.js)：

//= depend_on en.yml

这到你的/config/application.rb：

config.assets.paths << Rails.root.join("config", "locales")

Sprocket将检查该文件是否有变化.

此外,如果您决定通过编写自己的方法来执行此操作,请将它们注入Environment#context_class,如下所述：https://github.com/sstephenson/sprockets/blob/0d47a4fb459b170f2b2db7386ce7cbf9af1aa590/lib/sprockets/context.rb#L9-L22

第三：

你真的不应该在js.erb文件中使用i18n！即使你不关心代码气味,也可以考虑不要在生产中启用config.assets.compile,因为你会受到很大的性能影响.

更好的解决方案

可以在这个答案中找到：Rails: Internationalization of Javascript Strings?

然而：

为了完整起见,这是一个在您添加上述更改后将在开发中工作的示例：

/config/environments/development.rb

PartnerUrlApp::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations
  config.active_record.migration_error = :page_load

  config.assets.compile = true

  config.serve_static_assets = true

  config.assets.digest = true
  # Email
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = false
end

/app/assets/application.js.erb

<%= depend_on "en.yml" %>
<% I18n.backend.send(:init_translations) unless I18n.backend.initialized? %>
console.log(<%= I18n.backend.send(:translations).to_json %>);

/config/locales/en.yml

en:
  hello: "Hello world"

现在,加载我们的应用程序,我们在控制台中看到：

...
Started GET "/assets/application-240790de490ac241985d22ea6d94de38.js" for 127.0.0.1 at 2014-07-23 18:45:04 -0500
...

然后,更改yaml文件,并保存：

/config/locales/en.yml

en:
  hello: "DONT DO THIS!"

并且,在不重新启动服务器的情况下,我们可以看到由于我们的依赖性而重新编译了javascript：

...
Started GET "/assets/application-ddd20afc0453d275b63d846fee2a5fed.js" for 127.0.0.1 at 2014-07-23 18:45:24 -0500
