Build a slug with multiple fields

Question

Normaly I use

slug:
    type: slug
    uses: title

to define the slug in a Bolt contenttype. But now I would like to define it more like this:

slug:
    type: slug
    uses: date+title

How can this be done? What is the syntax to be used?

Answer 1

uses takes an array so something like this:

uses: [date, title]
