机车ecms App的资产

Question

我在Heroku上托管了一个LocomotiveCMS应用。此后，我一直直接在Heroku MongoHQ数据库上工作，并完成了这个网站。

然后，我将本地机器上的开发数据库设置为连接到HerokuApp使用的MongoHQ数据库，因此本地机器使用web上的实际数据。但是资产(CSS和JS文件)不能被正确访问。尽管我已经设置了AWS凭据。

所以，当我访问本地机器上的CSSS+JS文件时，我得到了文件，但没有内容，即空白文件。我也没有得到这些资产的AWS链接，就像我在Heroku服务器上看到的那样。

是否与资产预编译有关?我已经完全按照下面的描述设置了Heroku: http://doc.locomotivecms.com/guides/hosting/heroku-hosting

生产。Rb文件如下:

Testapp::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

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

  # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
  # config.assets.precompile += %w( search.js )
  # Disable delivery errors, bad email addresses will be ignored
  # config.action_mailer.raise_delivery_errors = false
  # Enable threaded mode
  # config.threadsafe!
  # 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
    config.action_mailer.delivery_method = :smtp
    config.action_mailer.smtp_settings = {
      :address        => 'smtp.sendgrid.net',
      :port           => 25,
      :authentication => :plain,
      :user_name      => ENV['SENDGRID_USERNAME'],
      :password       => ENV['SENDGRID_PASSWORD'],
      :domain         => ENV['SENDGRID_DOMAIN']
    }
end

Answer 1

在控制台中运行

bundle exec rake assets:precompile

然后push到git，再push到heroku

Answer 2

我理解为什么您将以下设置为config.assets.initialize_on_precompile = false，这使您的应用程序运行得更快。然而，ruby on rails指南声明如下:

如果你设置config.assets。Initialize_on_precompile为false，请确保在部署前测试rake资产:在本地预编译。当你的资产引用应用程序对象或方法时，它可能会暴露bug，因为不管这个标志的值是多少，它们仍然在开发模式的作用域内。

所以这可能是你的问题的途径。另外，如果您想包含额外的css和js，您可以在预编译数组中添加以下内容，如下所示:

config.assets.precompile += ['admin.js', 'admin.css']
