Create Writeable to HTTP response in play framework

1
votes

I defined a class in models/ResponseQuery as follows:

case class ResponseQuery(
  query: String,
  tableArray: Array[String]
)

In a file in app/controllers/ I return an object of type responseQuery

var responseQuery: models.ResponseQuery
Future.successful(Ok(responseQuery))

However, I get the following error while compiling:

Cannot write an instance of models.ResponseQuery to HTTP response. Try to define a Writeable[models.ResponseQuery]

I appreciate any help in solving this error.

Try with companion object to ResponseQuery and put implicit format for it.

import play.api.libs.json.Json

object ResponseQuery {
  implicit format = Json.format[ResponseQuery]
}
