Question

我刚刚通过Capistrano部署了一个网站。

除了我的css和js没有加载到页面上的标记外，它全部都去了plav：

<link data-turbolinks-track="true" href="/assets/application.css" media="all" rel="stylesheet" />
  <script data-turbolinks-track="true" src="/assets/application.js"></script>

我有上述内容但没有任何内容被加载，我收到404错误。

它在staging.rb中我最困惑，因为这是我目前用于部署的内容。

我的config / application.rb我有这个：

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(:default, Rails.env)

module Forge
  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)'

    # 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

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

    config.nav_lynx.selected_class = 'current'

  end
end

在development.rb中我有：

Forge::Application.configure do

  config.cache_classes = false

  config.eager_load = false

  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  config.action_mailer.raise_delivery_errors = false

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

  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.debug = true
end

在production.rb中我有：

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

  # Code is not reloaded between requests.
  config.cache_classes = true

  config.eager_load = true

  # Full error reports are disabled and caching is turned on.
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Disable Rails's static asset server (Apache or nginx will already do this).
  config.serve_static_assets = false

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

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

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

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


  # Set to :debug to see everything in the log.
  config.log_level = :info

  config.i18n.fallbacks = true

  config.active_support.deprecation = :notify

  config.log_formatter = ::Logger::Formatter.new
end

在staging.rb中我有：

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

# Code is not reloaded between requests
  config.cache_classes = true

  # Full error reports are disabled and caching is turned on
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = false

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

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

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

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation can not be found)
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners
  config.active_support.deprecation = :notify

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  # config.active_record.auto_explain_threshold_in_seconds = 0.5

end

似乎当我执行cap staging deploy时，它会编译资产，但在我的rails live app中，它们没有被加载。

任何人都可以指出我正确的方向，我在哪里出错了，我真的在这里敲打砖墙。

干杯

在资产：预编译之后，您需要重新启动服务器，以便rails开始使用摘要服务，因为它在启动时查找已编译的资产。在您的情况下，应用程序最有可能在没有任何编译资产的情Capistrano不会开箱即用。

通过触摸tmp / restart.txt文件可以重新启动Passenger。要允许capistrano重新启动乘客，请创建自定义rake任务：

namespace :deploy do
  desc 'Restart passenger without service interruption (keep requests in a queue while restarting)'
  task :restart do
    on roles(:app) do
      execute :touch, release_path.join('tmp/restart.txt')
    end
  end
end

并将其挂钩到capistrano deploy.rb中：

after 'deploy:publishing', 'deploy:restart'

此外，您的rake任务可以改进以检查您的服务器是否正在运行，然后相应地返回退出代码（在使用jenkins / hudson运行cap deploy时很有用）。当触摸tmp / restart.txt后第一个请求进入时，这也将立即重新启动乘客。请记住将“主页上的某些单词”替换为可在html中找到的任何单词。

namespace :deploy do
  desc 'Restart passenger without service interruption (keep requests in a queue while restarting)'
  task :restart do
    on roles(:app) do
      execute :touch, release_path.join('tmp/restart.txt')

      unless execute :curl, '-s -k --location localhost | grep "Some word on home page" > /dev/null'
        exit 1
      end
    end
  end
end

为什么我的live rails 4应用程序没有加载我的应用程序特定资产？
