为什么视图代码没有包装在类中？

Question

This is one of these "Why do things work in a certain way" questions.

Since Rails is a purely object oriented language, controller code, model code, helper code, migration code, etc. is wrapped inside classes. But not view code.

So I was wondering: how does Rails know that view code belongs to the Active View class ? How does that work internally?

Answer 1

All Ruby files run inside of a class, just run a file that contains this:

puts self.class.name

and you'll see that your code is wrapped in an Object class when it executes.
