Heroku分段網站上未顯示新圖像資產

Question

更新：我剛剛發現只有當我推到生產時，我的資產纔會出現在分期中。

每當我添加新的圖像資源，預編譯它們，並部署到分段，他們不會出現。然而，一切都在本地和生產上工作。這是我的代碼和我的過程，每當添加新的圖像資產。任何幫助，將不勝感激。我對此很新，並且到處尋找答案。

staging.rb

Rails.application.configure do 
    config.cache_classes = true 
    config.eager_load = true 
    config.consider_all_requests_local  = false 
    config.action_controller.perform_caching = true 
    config.action_mailer.default_url_options = { :host => 'http://site_name.herokuapp.com' } 
    config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present? 
    config.assets.js_compressor = :uglifier 
    config.assets.compile = false 
    config.assets.digest = true 
    config.log_level = :debug 
    config.action_controller.asset_host = Proc.new { |source| 
    if source =~ /\b(.png|.jpg|.gif|.svg)\b/i 
     "http://key.cloudfront.net" 
    end 
    } 
    config.i18n.fallbacks = true 
    config.active_support.deprecation = :notify 
    config.log_formatter = ::Logger::Formatter.new 
    config.active_record.dump_schema_after_migration = false 
end 

我如何預編譯我的資產分期

RAILS_ENV=staging bundle exec rake assets:precompile 

我如何預編譯我的資產進行生產

RAILS_ENV=staging bundle exec rake assets:precompile 

application.rb中

require File.expand_path('../boot', __FILE__) 

require 'rails/all' 

# Require the gems listed in Gemfile, including any gems 
# you've limited to :test, :development, or :production. 
Bundler.require(*Rails.groups) 

module InfoSite 
    class Application < Rails::Application 
    # Settings in config/environments/* take precedence over those  specified here. 
    # Application configuration should go into files in config/initializers 
    # -- all .rb files in that directory are automatically loaded. 

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. 
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC. 
    # config.time_zone = 'Central Time (US & Canada)' 

    config.serve_static_files = true 
    config.assets.compile = true 
    config.assets.configure do |env| 
     if Rails.env.development? || Rails.env.test? 
     env.cache = ActiveSupport::Cache.lookup_store(:memory_store) 
     end 
    end 
    # The default locale is :en and all translations from  config/locales/*.rb,yml are auto loaded. 
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*. {rb,yml}').to_s] 
    # config.i18n.default_locale = :de 

    # Do not swallow errors in after_commit/after_rollback callbacks. 
    config.active_record.raise_in_transactional_callbacks = true 
    end 
end 

我的用於添加圖片資源過程：

1. 將圖像中的應用程序/資產/圖像
2. 使用它在佈局（使用資產pipline：= image_tag'image.png'）
3. 本地檢查（一切正常）
4. 使用RAILS_ENV=staging bundle exec rake assets:precompile
5. 使用RAILS_ENV=production bundle exec rake assets:precompile
6. 檢查github上，所有資產被更新，我可以看到，他們已經預編譯
7. 混帳推分期主

現在，如果我認爲分期，資產回我一個空的圖像框，顯示圖像的名稱。

在我的過程中是否有某些我想念的東西？我應該採取不同的方法嗎？

轉到config/application.rb。 查找字符串config.assets.enabled並將值設置爲「true」。 或config.assets.initialize_on_precompile並設置爲true。
