在 Rails 中，to_label 和 to_s 有什么区别？

Question

In Rails, what's the difference between to_label and to_s ? Especially in the context of displaying model info in views. I know that if you define to_s you don't have to explicitly call Model.to_s in views. What's the advantage of using to_label then?

Answer 1

to_label has been deprecated, you can't find it from the Rails3 source

Answer 2

I believe the difference was that to_label did some magic in that converting values such as object class names to_s where as to_s just converts an object to a string.
