如何在Rails中简化日志显示 - 怎么在Rails中简化日志显示？

Rails

Rails默认的日志输出很详细，就是不精简，我们该如何优化呢？

1, Gemfile中添加lograge。

gem "lograge"

2, 在初始化器或相关环境配置中启用它。

# config/initializers/lograge.rb
# OR
# config/environments/production.rb
Rails.application.configure do
  config.lograge.enabled = true
end

3, 你可以添加自定义的一些内容。

Rails.application.configure do
  config.lograge.enabled = true

  config.lograge.custom_options = lambda do |event|
    { time: Time.now }
  end
end
