运行rails后无法生成日志

Question

运行 Rails 后，我无法在终端上看到日志，代码可以正常工作，没有任何问题。日志正在生成日志/development.log 文件由于没有日志我无法使用调试器

=> Booting Puma

config/dvelopment.log 文件

Rails.application.configure do
 
 
  config.active_storage.service = :local


  config.action_mailer.perform_caching = false
          
  config.assets.debug = true

  config.assets.quiet = true

  config.assets.raise_runtime_errors = true

  config.action_mailer.default_url_options = {
    host: Rails.application.secrets[:mailer_options][:host],
    port: Rails.application.secrets[:mailer_options][:port],
  }

  # ActiveRecord::Base.logger = ActiveSupport::Logger.new(STDOUT)

  config.lograge.enabled = true
  config.log_level = :debug
  config.lograge.formatter = Lograge::Formatters::Logstash.new

  config.lograge.custom_options = lambda do |event|
    {
      :time => Time.now.in_time_zone(Time.zone),
      :params => event.payload[:params].reject { |k| %w(controller action).include? k },
      :subdomain => event.payload[:subdomain],
      :remote_ip => event.payload[:remote_ip],
      :user_agent => event.payload[:user_agent],
      :uuid => event.payload[:uuid],
      :current_user => (event.payload[:current_user])? event.payload[:current_user][:id] : nil,
      :current_appuser => (event.payload[:current_appuser])? event.payload[:current_appuser][:id] : nil
    }
  end
  config.lograge.ignore_actions = ['PublicPagesController#status_check']

  config.logger = ActiveSupport::Logger.new(config.paths['log'].first, 7, 204857600)

     require "awesome_print"
end

Answer 1

当您想要在

STDOUT

环境中登录到

development

而不是日志文件时，请在

config/environments/development.rb

中更改此行

config.logger = ActiveSupport::Logger.new(config.paths['log'].first, 7, 204857600)

到

config.logger = Logger.new(STDOUT)

Answer 2

在单一模式下运行 Puma，它将恢复日志。

您必须在 Puma 配置文件中设置

workers 0

或删除该行。

它看到你的已设置为

workers 2
