如何查看我的gemfile中执行的所有查询以及类或方法？
[英]How I can see all the queries executed and classes or methods in my gemfile?
问题描述
I´m newbie in RoR and I would like to know how I can do two things in Rails (both versions 2 and 3): 
我是RoR的新手，我想知道如何在Rails中做两件事（版本2和3）：
How I can see all queries generated to database (save, update, find, etc.) in the console of the server?
如何在服务器的控制台中查看对数据库生成的所有查询（保存，更新，查找等）？ How I can see all the classes and methods of gems included in my Gemfile?
如何查看Gemfile中包含的gem的所有类和方法？ For example how I can see classes and methods of CanCan, Devise and so on.
例如，我如何查看CanCan，Devise等的类和方法。 gem "devise" gem "cancan" gem "rolify" gem "sass-rails"
And so on... 等等...
Sorry for my english and thank in advance!! 对不起，我的英语，谢谢！！

In your rails folder there will be a log sub-folder. 在rails文件夹中，将有一个日志子文件夹。 Depending on where your application is running and on your configurations you'll be able to see something similar to a development.log, staging.log or production.log file in that folder. 根据应用程序的运行位置和配置，您将能够在该文件夹中看到类似于development.log，staging.log或production.log文件的内容。
Also the .to_sql method can be used to show the sql. .to_sql方法也可以用于显示sql。 eg 例如
User.where(:id => 29).to_sql will yield the following: User.where(:id => 29).to_sql将产生以下结果：
"SELECT `users`.* FROM `users` WHERE `users`.`id` = 29"
For viewing gems. 用于查看宝石。 In terminal type bundle show devise this will return you a path. 在终端类型bundle show devise这将返回您的路径。 Go to that path. 去那条路。 All the necessary code will be present over there. 所有必要的代码将在那边显示。
