我一直在尝试将结果从scala form（映射到类模型）转换为json object，以便将此数据插入到（Mongo数据库）集合中。我正在使用 Play Framework 和 ReactiveMongo插件（启用JSON而不是BSON）。模型和表单如下所示：
case class LastVisit(selection: String = "", date: Option[Date] = None) extends ReadAndWriteTrait
case class AdminM(_id: Option[BSONObjectID], adminCreatedId: Option[Int], dateCreated: Option[Date], adminModifiedId: Option[Int], lastModified: Option[Date]) extends ReadAndWriteTrait
case class MyClass(usrId: Option[BSONObjectID] = None, numOfVisits: Option[Int] = None, lastVisit_e: Option[LastVisit] = None, admin_e: Option[AdminM]) extends SuperVarT with ReadAndWriteTrait
object MyClass extends SuperFormT with ReadAndWriteTrait {
implicit val lastVisitFormat: OFormat[LastVisit] = Json.format[LastVisit]
implicit val adminMFormat: OFormat[AdminM] = Json.format[AdminM]
implicit val myClassFormat: OFormat[MyClass] = Json.format[MyClass]
val form = Form(
mapping(
"usrId" -> optional(
text.transform(str2bson, bson2str)
),
"numOfVisits" -> optional(number),
"lastVisit_e" -> optional(mapping(
"selection" -> nonEmptyText,
"date" -> optional(date)
)(LastVisit.apply)(LastVisit.unapply)),
"admin_e" -> optional(mapping(
"_id" -> ignored(Option.empty[BSONObjectID]),
"adminCreatedId" -> optional(number),
"dateCreated" -> optional(date),
"adminModifiedId" -> optional(number),
"lastModified" -> optional(date).transform(date2Date, date2NowDate)
)(AdminM.apply)(AdminM.unapply))
)(MyClass.apply)(MyClass.unapply)
)
trait ReadAndWriteTrait {
implicit val dateRead: Reads[Date] = (__ \ "$date").read[Long].map {
date => new Date(date)
}
implicit val dateWrite: Writes[Date] = new Writes[Date] {
def writes(date: Date): JsValue = Json.obj(
"$date" -> date.getTime
)
}
}
令人沮丧的是，lastVisit_e.date字段作为Long类型而不是ISODate("date here")插入到数据库中 - 在Json中，Json.obj(s"$$date" -> JsNumber(dateLong here))为Action }} 状态。这是我正在路由的 def updateFromForm(collName: String, oId: Option[BSONObjectID], activeTabIdx: Int = 0) = Action.async { implicit request: Request[AnyContent] =>
MyClass.form.bindFromRequest.fold(
errorForm => Future.successful(Ok("TODO")),
data => {
/*
// todo - uncomment when formatting is correct
val doc = apiC.prepareData(data) // function used to transform/prepare data
update(collName, oId, doc, activeTabIdx)(request) // function to be called to update db collection
*/
val doc = Json.toJson(doc) // for test purposes
Future(Ok(doc.toString())) // for test purposes
}
)
}
函数，用于将表单中的数据更新到 Mongo Collection 。我刚刚定制它给我一个输出，以便我可以看到日期格式不正确：
{
"usrId":{
"$oid":"5a28258d9830b7614f566cc7"
},
"numOfVisits":5,
"lastVisit_e":{
"selection":"departure date",
"date":1496271600000
}
}
这是我得到的典型回应：
usrId $oid: "5a28258d9830b7614f566cc7"输出正确（lastVisit_e.date）但Long显示为#!/bin/sh
# Extract the desired information from the log message
# You can also use the information passed out by the central repo if its available
# %ae = Extract the user email from the last commit (author email)
USER_EMAIL=$(git log -1 --format=format:%ae HEAD)
# %an = Extract the username from the last commit (author name)
USER_NAME=$(git log -1 --format=format:%an HEAD)
# or use those values if you have them:
# $USER, $GIT_AUTHOR_NAME, $GIT_AUTHOR_EMAIL
if [ "$1" != refs/heads/master ] && [ CHECK_FOR_USER_NAME_OR_EMAIL ] {
echo "ERROR: you are not allowed to update master" >&2
exit 1
}
个数字。我怎样才能做到这一点？如果需要任何澄清，请告诉我。非常感谢。
