playframework-2.1

I have two classes, user and car. Both have ManyToMany mapping to each other. User: @Entity public class User extends Model { private int year; @ManyToMany(cascade=CascadeType.ALL) private List<Car> cars; } Car: @Entity public class Car extends Model { @ManyToMany(mappedBy = "cars", cascade=CascadeType.ALL ) private List<User> users; } Using ebean, I would like to query only those cars from year 1999 that have give user in their list. I do not want to iterate over the user's car list in Java code. I didn't find any documentation how many-to-many queries should look like. So I would something

In Kohana (PHP framework) the layout is implemented through Template_Controller which continas a member variable called $template, which serves as layout view. Then in the action method you can populate the $template with further sub-views, usually the content view. ( http://forum.kohanaframework.org/discussion/3612/kohana-layout-system/p1 ) This allows me to change the layout "theme" in the runtime. It is useful for multitenant system, where a tenant can select their own theme (two col, three col, etc.) How can I achieve that in playframework 2 Scala, with Scala template engine? In other

I'm playing with computer-database-jpa (Java) Play Framework 2.1 sample application. Everything works fine when I'm using H2 in memory database but I had problems when I want to connect the application with MySQL. Some one had the same problem ( Help wanted getting sample app connected to MySQL ) but there was no solution. I've added mysql-connector (Build.scala): val appDependencies = Seq( .... "mysql" % "mysql-connector-java" % "5.1.18" ) and edited application.conf: db.default.url="jdbc:mysql://password:user@localhost/my-database" db.default.driver=com.mysql.jdbc.Driver When I start the

I'm new to Play and in the process of configuring SSL for production. I can successfully run in dev mode with a self signed certificate, but when I try to use a signed certificate the initial client handshake fails and Play generates the following stack trace: play - Error loading HTTPS keystore from conf/keystore.jks java.security.NoSuchAlgorithmException: RSA KeyManagerFactory not available at sun.security.jca.GetInstance.getInstance(GetInstance.java:159) ~[na:1.7.0_11] at javax.net.ssl.KeyManagerFactory.getInstance(KeyManagerFactory.java:139) ~[na:1.7.0_11] at play.core.server.NettyServer

Let's say I have an action that optionally accepts two parameters: def foo(name: String, age: Integer) = Action { // name & age can both be null if not passed } How do I setup my route file to work with any of the following call syntaxes: /foo /foo?name=john /foo?age=18 /foo?name=john&age=18 /foo?authCode=bar&name=john&age=18 // The controller may have other implicit parameters What is the correct syntax for this? Something like this should work: GET /foo controllers.MyController.foo(name: String ?= "", age: Int ?= 0) Since your parameters can be left off you need to provide default values for

I have this: package models import play.api.libs.json._ import play.api.libs.functional.syntax._ object ModelWrites { implicit val tmoWrites= Json.writes[TestModelObject] implicit val ihWrites = Json.writes[IntHolder] } case class TestModelObject(s1:String, s2:String) case class IntHolder(i1:Int, i2:Int) trait HasInts { val ints: List[IntHolder] } When I do this: scala> val tmo = new TestModelObject("hello", "world") with HasInts { val ints = List(IntHolder(1,2), IntHolder(3,4)) } scala> Json.toJson(tmo) res0: play.api.libs.json.JsValue = {"s1":"hello","s2":"world"} how can I implicity
