scopes with lambda and arguments in Rails 4 style?

Question

I\'m wondering how the following is done in Rails 4 or if I just use the Rails 3 approach for using a lambda that can pass an argument the same way with 4 as I do with 3.

Answer 1

Rails 4, you can do:

scope :find_lazy, -> (id) { where(id: id) }

That was in the old ruby:

:id => id

Better hash:

id: id
