每当我尝试启动服务器时，我总是收到此错误，但validate_options': Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)我似乎无法解决问题！我几乎可以肯定这个问题是导致Carrierwave和foge gems使用amazon s3造成的。但我不确定问题到底在哪个文件夹中！

这是我的初始化程序/carrierwave.rb：

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider => 'AWS',                        # required
    :aws_access_key_id  =>   ENV["S3_ACCESS_KEY"],                        # required
    :aws_secret_access_key => ENV["S3_SECRET_KEY"]                      # required
  }
  config.fog_directory  = ENV["S3_BUCKET"]                          # required
end

这是我的日志：

我想禁用提交按钮，直到我的输入字段被填写。我是 Rails 新手，对 JS 和 Coffee 不太了解，我一直在尝试运行此功能，但它无法正常工作。我还尝试在客户端进行验证，但无法使其工作，代码通过，但即使填写了所有字段，按钮仍然未启用。由于某种原因，该按钮继续处于禁用状态。
