Hi all I have defined a table with custom primary key:

object Genders : Table() {
    val value: Column<String> = varchar("value", 1)
    val description: Column<String> = varchar("description", 20)
    override val primaryKey = PrimaryKey(value)
}

As next, I would like to create an Entity class for it and I have tried:

class Gender(v: EntityID<String>) : Entity<String>(v) {
    companion object : EntityClass<String, Gender>(???)

    var value by Genders.value
    var description by Genders.description
}

EntityClass

expects an `IdTable`: For example

object Genders : IdTable<String>() {
    override val id = varchar("value", 20).entityId()
    val description: Column<String> = varchar("description", 20)
    override val primaryKey: PrimaryKey? = PrimaryKey(id)
}
class Gender(id: EntityID<String>) : Entity<String>(id) {
    companion object : EntityClass<String, Gender>(Genders)
    var description by Genders.description
}

You can read more about that here: https://github.com/JetBrains/Exposed/wiki/DAO#overview

How do you know regarding the

IdTable

? In doc, it does not mention about the

IdTable

.
