serializing objects to json with play.api.libs.json

Question

I\'m trying to serialize some relatively simple models into json. For example, I\'d like to get the json representation of:

case class User(val id: Long, val fir         


        

Answer 1

Thanks to the fact User is a case class you could also do something like this:

implicit val userImplicitWrites = Json.writes[User]
val jsUserValue = Json.toJson(userObject)

without writing your own Format[User]. You could do the same with reads:

implicit val userImplicitReads = Json.reads[User]

I haven't found it in the docs, here is the link to the api: http://www.playframework.com/documentation/2.2.x/api/scala/index.html#play.api.libs.json.Json$
