Converting from JsResultException to JsError - scala

Question

I have Json that may have spaces in it which I'd like to trim. I created this case class to parse with Json.parse(...).as[PersonalInfo] but the issue is that it fails on the first failed read and also doesn't return a JsError. How would I define the JsError case while also preserving the errors for every field that wasn't parsed correctly?
case class PersonalInfo(
email: String,
password: String,
firstName: String,
lastName: String
)
object PersonalInfo {
implicit val personalInfoReads = new Reads[PersonalInfo] {
override def reads(json: JsValue): JsResult[PersonalInfo] = {
val email = (json \ "email").as[String].trim
val password = (json \ "password").as[String].trim
val firstName = (json \ "firstName").as[String].trim
val lastName = (json \ "lastName").as[String].trim
JsSuccess(PersonalInfo(email, password, firstName, lastName))
}
}
}

Answer 1

See my answer here
In two words: do not use as in reads. In case of failed parsing it throws exception. Use validate. Example you can find by link above
Update
Well, if you want solution..
case class PersonalInfo(email: String,
password: String,
firstName: String,
lastName: String)
object PersonalInfo {
implicit val personalInfoReads = new Reads[PersonalInfo] {
override def reads(json: JsValue): JsResult[PersonalInfo] = {
for {
email <- (json \ "email").validate[String]
password <- (json \ "password").validate[String]
firstName <- (json \ "firstName").validate[String]
lastName <- (json \ "lastName").validate[String]
} yield PersonalInfo(
email.trim(),
password.trim(),
firstName.trim(),
lastName.trim()
)
}
}
}

My idea is to use the standard format (you can also use read) of play-json
And then add a function to get it trimmed:
case class PersonalInfo(
email: String,
password: String,
firstName: String,
lastName: String
) {
def trimmed() = PersonalInfo(
email.trim,
password.trim,
firstName.trim,
lastName.trim
)
}
object PersonalInfo {
implicit val customWrites: OFormat[PersonalInfo] = Json.format[PersonalInfo]
}
You can use it like that:
json.validate[PersonalInfo] match {
case JsSuccess(info: PersonalInfo, _) =>
info.trimmed()
case JsError(errors) =>
error("Other than RunAdapter: " + errors.toString())
}
The errors is a list of all validation errors.
