在Materialise.css中获取视差效果需要任何特殊图像吗？(Do you need any special image for getting Parallax effect in Materialize.css?)

 不知道您是否仍需要帮助，但如果您希望能够将环境变量存储在文件中，则可以使用使用zeus init生成的custom_plan.rb 。 以下是我的文件的副本。 我正在使用Omniauth并且需要我的密钥可以轻松更改。 您可以通过重载server方法来添加仅服务器变量，只需知道您的初始化程序将在服务器命令之前运行。 
 
require 'zeus/rails'

class CustomPlan < Zeus::Rails

  def boot

    # Omniauth Keys

    # GOOGLE+
    ENV['GPLUS_KEY']       = 'xxx'
    ENV['GPLUS_SECRET']    = 'xxx'

    # FACEBOOK
    ENV['FACEBOOK_KEY']    = 'xxx'
    ENV['FACEBOOK_SECRET'] = 'xxx'

    super # Finish boot
  end
end

Zeus.plan = CustomPlan.new

Don't know if you still need help with but if you want to be able to store environmental variables in a file you can use the custom_plan.rb that is generated with zeus init. Below is a copy of my file. I am using Omniauth and need my keys to be easily changeable. You can add server only variables by overloading the server method instead, just know that your initializers will be ran before the server command.
 
require 'zeus/rails'

class CustomPlan < Zeus::Rails

  def boot

    # Omniauth Keys

    # GOOGLE+
    ENV['GPLUS_KEY']       = 'xxx'
    ENV['GPLUS_SECRET']    = 'xxx'

    # FACEBOOK
    ENV['FACEBOOK_KEY']    = 'xxx'
    ENV['FACEBOOK_SECRET'] = 'xxx'

    super # Finish boot
  end
end

Zeus.plan = CustomPlan.new
