JarCastingmongodb-dao
Contains some common functionality when working with MongoDb together with Reactivemongo
Usage
libraryDependencies ++= Seq(
"com.github.durre" %% "mongodb-dao" % "1.2.2",
// This is a bit akward due to a bug in sbt I believe
("com.github.durre" %% "mongodb-dao" % "1.2.2" % "test").classifier("tests")
)
The dao
import se.durre.mongodb.formats.CommonDbFormats._
case class Person(
id: UUID,
name: String
)
class PersonDao(db: DefaultDB) extends MongoDao[Person, UUID](db, collectionName = "persons") {
override protected implicit def reader: BSONDocumentReader[Person] = new BSONDocumentReader[Person] {
override def read(bson: BSONDocument): Person = {
(for {
id <- bson.getAs[UUID]("_id")
name <- bson.getAs[String]("name")
} yield Person(id, name)).get
}
}
override protected implicit def writer: BSONDocumentWriter[Person] = new BSONDocumentWriter[Person] {
override def write(t: Person): BSONDocument = BSONDocument(
"_id" -> t.id,
"name" -> t.name
)
}
}
Configuration
In your application.conf
mongodb {
uri = "mongodb://localhost:27017/testdb"
}
Create a connection
val config = ConfigFactory.load()
MongoContext.connect(config.getConfig("mongodb")).map { db =>
val dao = new PersonDao(db)
}
Writing tests
You can use the supplied helper class, MongoDbTest.
class PersonDaoSuite extends MongoDbTest {
val dao = new PersonDao(db)
// These collections will be dropped before & after each test
override def touchedCollections: Set[String] = Set(dao.collectionName)
test("insert a document") {
val person = Person(
id = UUID.randomUUID(),
name = "Bob"
)
dao.insert(person).futureValue
val found = dao.findById(person.id).futureValue
found shouldBe Some(person)
}
}
