Question

我有aws.yml

development:
  asset_host: 'abcd1234efgh@cloudfront.net'

我创建了assets.rb

AWS_CONFIG = Rails.application.config_for(:aws)
unless (AWS_CONFIG.nil? || AWS_CONFIG['asset_host'].nil?)
  Rails.application.config.asset_host = AWS_CONFIG['asset_host']
end

如果aws.yml不存在，我正在尝试实现逻辑，那么它应该完全爆炸并阻止rails服务器启动。知道我怎么能实现这个目标？

Answer 1

您可以根据自己的情况提出错误。

raise "Essential file doesn't exist"

Answer 2

您应该将此代码放在初始化程序中并检查

AWS_CONFIG = Rails.application.config_for(:aws)
unless (AWS_CONFIG.nil? || AWS_CONFIG['asset_host'].nil?)
  raise "AWS file doesn't exist"
end

并检查

unless File.exist? File.expand_path "aws.ics" #proper path of your file
   raise "AWS file doesn't exist"
end

如果文件不存在，则阻止rails服务器启动
