Required attribute

[vladra]

Hi guys

I was wondering if there is an ability to mark attribute as required. So if attribute is not passed in this case, it should raise some error. I found required option for attribute, but not sure how to use it.

So, is it possible to require mandatory attribute?

Thanks for help!

I will specify question a bit. It's actually working with build in types, just haven't tried that (with String for example). But is doesn't work with my models (for example User).

With build in type:
attribute :city, String
=> Virtus::CoercionError: Failed to coerce attribute city from nil into String

With my mode:
attribute :user, User
=> no failure error
