How to Handle Option #54

Closed lenzenc closed 9 years ago

lenzenc commented 9 years ago

I'm trying to figure out what is the best practice for handling Option, for example;

 case class Person(name: String, age: Option[Int] = None)

implicit val personValidator = validator[Person] { p =>
    p.name is notEmpty
    p.age is between(21, 40)
}

In this case I only want to validate "age" if it is Some.

Thoughts?

You can use .each for that (i.e. p.age.each is between(...)). It should be covered in the documentation on the project site, though - is it not clear enough?

Thanks, will give that a try. As far as I can see I don't see any documentation about using "each"; http://wix.github.io/accord/

It's at http://wix.github.io/accord/dsl.html. The site could really use a TOC, and I could really use some help from anyone conversant in CSS to get it done properly :-)
