问题描述
在我的项目中,必须将位置数据保存在表上,因此我创建了以下表
create table if not exists public.person(
email varchar(255) not null primary key,name varchar(255) not null,surname varchar(255) not null,location point
)
连同相关实体/表格:
case class Person(email: String,name: String,surname: String,location: Point)
class People(tag: Tag) extends Table[Person](tag,"person") {
def email: Rep[String] = column[String]("email")
def name: Rep[String] = column[String]("name")
def surname: Rep[String] = column[String]("surname")
def location: Rep[Point] = column[Point]("location")
def pk = primaryKey("pk",email)
def * : ProvenShape[Person] =
(email,name,surname,location) <> (Person.tupled,Person.unapply)
}
然后我按照此处指定的方式创建了扩展个人资料:
trait ExtendedProfile
extends ExPostgresProfile
with PgDateSupport
with PgDate2Support
with PgPostGISSupport {
override val api: API = new API {}
trait API
extends super.API
with SimpleDateTimeImplicits
with DateTimeImplicits
with PostGISImplicits
with PostGISAssistants
val plainAPI = new API
with ByteaPlainImplicits
with Date2DateTimePlainImplicits
with PostGISPlainImplicits {}
}
object ExtendedProfile extends ExtendedProfile
每当我尝试在数据库中插入一个人时,都会出现以下错误:org.postgresql.util.PSQLException: ERROR: column \"location\" is of type point but expression is of type bytea
