我如何獲得Ruby類的名稱？ - How do I get the name of a Ruby class?

問題：

How can I get the class name from an ActiveRecord object? 如何從ActiveRecord對象獲取類名？

I have: 我有：

result = User.find(1)

I tried: 我試過了：

result.class
# => User(id: integer, name: string ...)
result.to_s
# => #<User:0x3d07cdc>"

I need only the class name, in a string ( User in this case). 我只需要字符串中的類名（在本例中爲User ）。 Is there a method for that? 有沒有辦法呢？

I know this is pretty basic, but I searched both Rails' and Ruby's docs, and I couldn't find it. 我知道這是非常基本的，但我搜索了Rails和Ruby的文檔，我找不到它。
