[英]In Ruby on rails, how can I figure out which class mix in which module?
我是Rails的新手，我想找到某种方法来获取某些类中可用的方法？
我应该签出在线文档或使用ri工具，如果有一个图形工具来显示每个类与模块之间的关系，那将是非常棒的。
如果您只想查看可用于任何类的方法，请尝试以下操作：
CLASS_NAME.methods # list of all methods available
CLASS_NAME.instance_methods # list of all instance methods
CLASS_NAME.public_instance_methods # list of all instance methods which are public
CLASS_NAME.private_instance_methods # list of all instance methods which are private
CLASS_NAME.protected_instance_methods # list of all instance methods which are protected
