# Scala ActiveRecord [![maven central](https://maven-badges.herokuapp.com/maven-central/com.github.aselab/scala-activerecord_2.13/badge.svg)](https://maven-badges.herokuapp.com/maven-central/com.github.aselab/scala-activerecord_2.13) [![javadoc](http://javadoc-badge.appspot.com/com.github.aselab/scala-activerecord_2.13.svg?label=scaladoc)](http://javadoc-badge.appspot.com/com.github.aselab/scala-activerecord_2.13/com/github/aselab/activerecord/index.html?javadocio=true)

scala-activerecord is an ORM library for Scala.

This library is inspired by ActiveRecord of Ruby on Rails.

It is designed following the CoC(Convention over Configuration), DRY(Don't Repeat Yourself) principles.

## Minimal example

* Sample snippet: **[Scastie](https://scastie.scala-lang.org/N5fy1pUZRWWqq8cwLHCgeQ)**

Model implementation:

```scala

package models

import com.github.aselab.activerecord._

import com.github.aselab.activerecord.dsl._

case class Person(name: String, age: Int) extends ActiveRecord

object Person extends ActiveRecordCompanion[Person]

```

Schema definition:

```scala

package models

import com.github.aselab.activerecord._

import com.github.aselab.activerecord.dsl._

object Tables extends ActiveRecordTables {

  val people = table[Person]

}

```

ActiveRecord model usage:

```scala

import com.github.aselab.activerecord.dsl._

import models._

import scala.language.postfixOps

object App extends App {

  Tables.initialize

  

  Person("person1", 25).save()

  Person("person2", 18).save()

  Person("person3", 40).save()

  Person("person4", 18).save()

  Person.findBy("name", "person1") //=> Some(Person("person1", 25))

  Person.findBy("age", 55) //=> None

  Person.findAllBy("age", 18).toList //=> List(Person("person2", 18), Person("person4", 18))

  Person.where(_.age.~ >= 20).orderBy(_.age desc).toList //=> List(Person("person3", 40), Person("person1", 25))

  

  Tables.cleanup

}

```

Schema and query DSL is based on [Squeryl](http://squeryl.org/).
