He mentioned that:
And I have some good news too, we will be introducing a feature like this into Play soon.
I don't recall seeing anything like this in the official Play docs.
user table, generate the model, play form wrapper, and stubbed out CRUD controller methods along with corresponding GET/POST/PUT/DELETE routes.
sbt "runMain com.example.Class" but I keep getting an error Expected whitespace character - has anyone encountered this before? Any work-around for it?
I tried to implement an error handler (https://www.playframework.com/documentation/2.8.x/ScalaErrorHandling) but they are not invoked (case no exception was thrown).
Any suggestions?
Hello,
My application uses Play, ReactiveMongo Scala driver and Mongo DB. I have the following versions of these components:
“com.typesafe.play” %% “play-json” % “2.5.18”
“ai.x” %% “play-json-extensions” % “0.9.0”
“com.typesafe.play” %% “play” % “2.5.18”
“com.typesafe.play” %% “play-ws” % “2.5.18”
“org.reactivemongo” %% “play2-reactivemongo” % “0.20.3-play25”
“org.reactivemongo” %% “reactivemongo-play-json” % “0.20.3-play25”
“org.reactivemongo” % “reactivemongo-bson_2.11” % “0.20.3”
“org.reactivemongo” %% “reactivemongo” % “0.20.3”
There is a JSON object in MongoDB that looks like this:
“status” : {
“siteStatus” : “InProgress”,
“timestamp” : NumberLong(“1585696318513”),
“timestampLocalDateTime” : “2020-03-31T23:11:58”
}
When our application tries to read this object, we get this error:
JsResultException(errors:List((,List(ValidationError(List(error.expected.jsnumber),WrappedArray())))))
The attribute that is causing this error is this: “timestamp” : NumberLong(“1585696318513”). Play Framework expects it to be in this format: “timestamp” : “1585696318513” but Mongo DB stores it by adding some additional type information which they call Extended-JSON.
The Scala class corresponding to this JSON is:
case class TemplateSiteStatus(siteStatus: SiteStatus, timestamp: Long, timestampLocalDateTime: Option[LocalDateTime] = None, msg: Option[String] = None)
object TemplateSiteStatus {
implicit val format: OFormat[TemplateSiteStatus] = Json.format[TemplateSiteStatus]
}
We never had any issues parsing this JSON when we were using the older version of the reactivemongo driver that is compatible with the following play-reactiveMongo framework:
“org.reactivemongo” %% “play2-reactivemongo” % “0.12.4”
This error only started happening after we upgraded to “play2-reactivemongo” % “0.20.3-play25”. Any idea how to work around this? We need to use the newer version for different reasons and cannot stay on the older version. Please help.
Thank you.
0.20.3-hotfix1, that might work for you? https://search.maven.org/artifact/org.reactivemongo/play2-reactivemongo_2.11 https://github.com/reactivemongo/play-reactivemongo/compare/0.20.2...0.20.3-hotfix1

Hello,
I need to log metrics for requests in play framework, for example for the route
/user/:userId app.controllers.getUser(userId: String)in my customer filter I want to log the metrics for /user/:userId ie. the route and not the exact URI (/user/123, /user/345 etc).
how do I go about getting the route from the request URI in the filter:
class MetricsFilter @Inject()(implicit val mat: Materializer, ec: ExecutionContext, registry: MeterRegistry) extends Filter with Logging {
override def apply(nextOperation: RequestHeader => Future[Result])(requestHeader: RequestHeader): Future[Result] = {
val chain = nextOperation(requestHeader)
chain
}
}
I have the weirdest of problems. I have the following code:
case class SearchableValuesQuery(
values: List[String],
mode: Option[SearchMode] = Some(SearchMode.AND)
)
object SearchableValuesQuery {
implicit val jsonFormat: OFormat[SearchableValuesQuery] = Json.format[SearchableValuesQuery]
}Whenever I try to instantiate SearchValuesQuery, I get an UninitializedFieldError:
Caused by: sbt.ForkMain$ForkError: scala.UninitializedFieldError: Uninitialized field: .../SearchService.scala: 201
at ....SearchService$SearchableValuesQuery$.jsonFormatjsonFormat this way: implicit val jsonFormat: OFormat[SearchableValuesQuery] = new OFormat[SearchableValuesQuery] {
override def writes(o: SearchableValuesQuery): JsObject = Json.writes[SearchableValuesQuery].writes(o)
override def reads(json: JsValue): JsResult[SearchableValuesQuery] = Json.reads[SearchableValuesQuery].reads(json)
}
