Usage

Create your own Slick-Profile

this example includes the slick mysql profile with the spatial extension

package your.package

import com.foerstertechnologies.slickmysql.{ExMySQLProfile, MySQLSpatialSupport}

trait MySQLSpatialProfile extends ExMySQLProfile
  with MySQLSpatialSupport {

  override val api = new MyAPI {}

  trait MyAPI extends API
    with MySQLSpatialImplicits with MySQLSpatialAssistants
}

object MySQLSpatialProfile extends MySQLSpatialProfile

You can also use com.foerstertechnologies.slickmysql.MySQLSpatialProfile which comes with the JTS package.

Register your profile

For slick play: Set your own profile in your config

slick.dbs.default.profile = "your.package.MySQLSpatialProfile$"

In your code

Gps example with JTS

import your.package.MySQLSpatialProfile
import play.api.db.slick.HasDatabaseConfigProvider
import org.locationtech.jts.geom.Point

case class Test(id : Long, gps : Point)

class TestTable(tag: Tag) extends Table[Test](tag, Some("xxx"), "Test") {
  def id = column[Long]("id", O.AutoInc, O.PrimaryKey)
  def gps = column[Point]("location")

  def * = (id, gps) <> (Test.tupled, Test.unapply)
}


trait MyTestClass extends HasDatabaseConfigProvider[MySQLSpatialProfile]
{
    import profile.api._
    
    def findAroundPoint(position: Point, limit : Int) : DBIO[Seq[Test] = {
        TestTable.sortBy(_.gps.distanceSphere(position)).take(limit).result
    }
}

Documentation

JTS

Stored SRID Values

The Geometry values are stored and loaded with the given SRID.
Make sure to add SRID to your value when you save it. Otherwise SRID 0 will be used as default value by mysql. For computations on multiple geometry values, all values must have the same SRID or an error occurs.
