I would like to return a partial object in a response for another object type.

For example, I have a UserProfile model:

 var id: Int?
 var email: String
 var firstName: String?
 var lastName: String?

and an Adult model:

 var id: Int?
 var nickname: String
 var type: String
 var user: User.UserProfile
 var family: Family

Say I would like to return just the UserProfile's email address in the Adult response, what is the way to go about that?

I have tried an approach with child/parent relationships, where my Adult model is more like:

 var id: Int?
 var nickname: String
 var type: String
 var user: User.ID
 var family: Family

..but then my response just contains an object ID, but I really want to return a partial (or even full in some cases) object.

Thanks in advance.

The way this is done is to create a 'public' definition of your model, which will represent the JSON you return from your route.

For your model, you might create a struct like this:

struct AdultResponse: Content 
 var id: Int?
 var nickname: String
 var type: String
 var email: String
 var family: Family

 init(adult: Adult) 
 self.id = adult.id
 self.nickname = adult.nickname
 self.type = adult.type
 self.email = adult.user.email
 self.family = adult.family
 

You can then get your Adult model from the database, create an AdultResponse and return that from your route.

  Thanks. However whenever I declare a struct with a property of type Family for example, I get back the error "operator does not exist: jsonb = bigint" in the response.
