Hey guys, am having a small problem in declaring a primary key in table. Am using Exposed framework and my base table is Table("users"). unfortunately, am unable to declare my user_id as a primary key. I get this error
Unresolved reference: primaryKey

here is my table implementation
object Users : Table("users"){
val userId: Column<Int> = integer("user_id").autoIncrement("user_id_seq").primaryKey()
val createdAt = datetime("created_at").defaultExpression(CurrentDateTime)
val updatedAt = datetime("updated_at").defaultExpression(CurrentDateTime)
val accountId = integer("account_id")
val msisdn = varchar("msisdn", length = 100).nullable()
val firstName = varchar("first_name", length = 100).nullable()
val middleName = varchar("middle_name", length = 100).nullable()
val lastName = varchar("last_name", length = 100).nullable()
val emailAddress = varchar("email_address", length = 100).nullable()
val username = varchar("username", length = 100).nullable()
val password = varchar("password", length = 100).nullable()
val userStatus = char("user_status", length = 8)
}

Version 0.36.1 moved away from Column.primaryKey(). A primary key can now be declared like this:

object Users : Table("users") {
    val userId: Column<Int> = integer("user_id").autoIncrement("user_id_seq")
    // other columns

    override val primaryKey = PrimaryKey(userId)
}
