用Slick持久化ScalaFxBean

≡放荡痞女 提交于 2019-12-03 08:24:40
一直想给ScalaFX找一个合适的持久曾框架,要越方便越好。 接触Scala之前玩的是JavaFX,曾用熟悉的Mybatis写持久层,JavaFxBean的Properties不能用IDE自动生成用于Mybatis的getter和setter。比方说一个属性 private fianl IntegerProperty age = new SimpleIntegerProperty(this, "age", 20); 用Eclipse或IDEA可以生成如下getter和setter public IntegerProperty getAge() { return age; } public void setAge(IntegerProperty age) { this.age = age; } 然而持久层框架需要的(也就是JavaFxBean的标配)是这样的getter和setter public String getName() { return name.get(); } public void setName(String name) { this.name.set(name); } public StringProperty nameProperty() { return name; } 自己写过一个简单的工具用来生产这样的getter和setter,但仍嫌麻烦。

Why does Slick generate a subquery when take() method is called

I use Slick 1.0.0-RC1. I have this definition for table object: object ProductTable extends Table[(Int, String, String, String, Double, java.sql.Date, Int, Option[Int], Int, Boolean)]("products") { def id = column[Int]("productId", O.PrimaryKey, O.AutoInc) def title = column[String]("title") def description = column[String]("description") def shortDescription = column[String]("shortDescription") def price = column[Double]("price") def addedDate = column[java.sql.Date]("addedDate") def brandId = column[Int]("brandId") def defaultImageId = column[Option[Int]]("defaultImageId") def visitCounter =

Mapped projection with <> to a case class with companion object in Slick

江枫思渺然 提交于 2019-12-03 08:03:18
With Slick, I am trying to project database table entries directly to the case class they represent. Following the example in the documentation , I set up a mapped projection using the <> operator: case class SomeEntity3(id: Int, entity1: Int, entity2: Int) val SomeEntityTable = new Table[SomeEntity3]("some_entity_table") { def id = column[Int]("id", O.PrimaryKey, O.AutoInc) def entity1 = column[Int]("entity1") def entity2 = column[Int]("entity2") def * = id ~ entity1 ~ entity2 <> (SomeEntity3, SomeEntity3.unapply _) } Now, I'd like to add some static constants and auxiliary methods to

Slick 3.0.0 database agnostism

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I started to use Slick 3.0.0 and I like it's succinct syntax. Nevertheless, I wasn't able to find a way to use it in a database agnostic way. In the following example provided in the documentation: http://slick.typesafe.com/doc/3.0.0/gettingstarted.html I'd like to be able to decouple somehow this code of the database used and avoid importing database specific in my code (i.e slick.driver.H2Driver.api._ ). I tried to get rid of it by providing the connection using the cake pattern, but the ".result" member isn't available then. A workaround

Is Slick 3.0 reactive/asynchronous at the database driver level? For which databases?

左心房为你撑大大i 提交于 2019-12-03 07:33:02
问题 Slick has historically relied on JDBC drivers, which internally block waiting for socket I/O in response to queries. Every outstanding database call requires a thread to block on a socket; hence, it's not really reactive in the same sense as ReactiveMongo, postgresql-async and mysql-async, which are asynchronous all the way down. Has anything changed in this regard in Slick 3.0? Or am I confused about any of this? 回答1: It is not async down to the driver level, but that is not a problem. The

Slick left outer join fetching whole joined row as option

问题 My join looks like this: def byIdWithImage = for { userId <- Parameters[Long] (user, image) <- Users leftJoin RemoteImages on (_.imageId === _.id) if user.id === userId } yield (user, image) but slick fails at runtime when user.imageId is null [SlickException: Read NULL value for column RemoteImage.url] Changing the yield to } yield (user, image.?) gives me a compile time exception, it only works on individual columns could not find implicit value for evidence parameter of type scala.slick

How do you run a patch/partial database UPDATE in Scala Slick?

依然范特西╮ 提交于 2019-12-03 07:03:33
问题 We'd like to run a patch/partial UPDATE with Slick (3.0.0) so that we only modify some of the fields in a record. Exactly which fields will be updated exactly will only be known at runtime. For example, for a REST PATCH request. Currently we run a SELECT first to get the original record then run an UPDATE but it would be nicer to do this in a single SQL statement. Something like this: def patchPerson(name: Option[String], age: Option[Int]) = { people.filter(_.name === "M Odersky") .map(p =>

How to persist enum value in slick

问题 I have the follow enum: object LoginStatus extends Enumeration() with BitmaskedEnumeration { type LoginStatus = Value val Active = Value("A") val Inactive = Value("I") } I need to persist the value of the enum "A", but when the sql is generated the result is 0. this is the table mapping: object LoginTable extends Table[Login]("login") { def idLogin = column[Int]("idlogin", O.PrimaryKey, O.AutoInc) def cdLogin = column[String]("cdlogin", O.NotNull) def cdPass = column[String]("cdPass", O

scala slick one-to-many collections

旧巷老猫 提交于 2019-12-03 05:27:39
I have a database that contain activities with a one-to-many registrations relation. The goal is to get all activities, with a list of their registrations. By creating a cartesian product of activities with registrations, all necessary data to get that data is out is there. But I can't seem to find a nice way to get it into a scala collection properly; let's of type: Seq[(Activity, Seq[Registration])] case class Registration( id: Option[Int], user: Int, activity: Int ) case class Activity( id: Option[Int], what: String, when: DateTime, where: String, description: String, price: Double )
