我想动态确定当前方法定义的类.
这是我正在尝试做的一个静态示例：
class A
def foo
puts "I was defined in A"
end
end
class B < A
def foo
puts "I was defined in B"
super
end
end
A.new.foo
# I was defined in A
B.new.foo
# I was defined in B
# I was defined in A <- this is the tricky one
如何用动态表达式替换上面字符串中的A和B？
显然,#{self.class}不起作用. (它会打印我在B中定义为B两次)
我怀疑答案是“你不能”,但也许我忽略了一些东西.
解决方法
那这个呢？
class A
def foo
puts "I was defined in #{Module.nesting.first}"
end
end
class B < A
def foo
puts "I was defined in #{Module.nesting.first}"
super
end
end
