Rails 开发环境日志过大时自动删除

新建文件：config/initializers/clear_logs.rb

例：开发模式下当日志大于10m时自动清理

# config/initializers/clear_logs.rbif Rails.env.development?  MAX_LOG_SIZE = 10.megabytes  logs = [ File.join(Rails.root, 'log', 'development.log'), File.join(Rails.root, 'log', 'test.log') ]  logs.each do |log|    if File.size?(log).to_i > MAX_LOG_SIZE      $stdout.puts "Removing Log: #{log}"      `rm #{log}`    end  endend
