For that I have to import: javax.persistence.* and play.db.ebean.* but none of them can be found. The error is package javax.persistence does not exist What should I do?

Asset mapping outside public folder on Play framework

由 寵の児 提交于 2019-12-01 18:14:33
问题 We have huge list of images that we need to store in an external path.. i.e outside of play application folder. How can we make it available to play as an asset so it streams it as a web server? 回答1: You've probably seen Play's documentation about Assets. Additionally to Play's standard assets you can define your own. In conf/routes you need to add a line for your external asset: # Static resources (not managed by the Play framework) GET /my_external_assets/*file controllers.ExtAssets.at(file

Play 2.2 match if there exists an implicit Json converter

由 北慕城南 提交于 2019-12-01 08:16:59
I have put all my Json converters in one file JsonUtil, and then have a convertToJson method which tries to convert any object passed to json. Basically a structure like this: implicit val format_A = format[A] implicit val format_B = format[B] def convertToJson(o: Any): JsValue = o match { case a: A => Json.toJson(a) case b: B => Json.toJson(b) case a: Any => Logger.warn("could not convert to json: "+a); JsNull } but with alot more formatters / cases. I don't want to import all these implicits when I need conversions (for various reasons). Is there a way to match if there exists a valid toJson

No Json serializer found for type Seq[(String, String)]. Try to implement an implicit Writes or Format for this type

I want to convert a Seq[(String, String)] into JSON with Scala play, but I face this error: No Json serializer found for type Seq[(String, String)]. Try to implement an implicit Writes or Format for this type. How can I fix this? It depends on what you're trying to achieve. Say you have a Seq[(String, String)] like this: val tuples = Seq(("z", "x"), ("v", "b")) If you are trying to serialize it as following: { "z" : "x", "v" : "b" } Then just use Json.toJson(tuples.toMap) . If you'd like to have some custom representation of your tuples you can define a Writes as the compiler suggests:
