android - Roomdb does know how to return field when it has default value?

Question

This work very well

@Entity
data class OrderVoucher(
        @PrimaryKey var id: Int? = null,
        var orderId: Int? = null,
       var printCount: Int? = null
}

but when I add defult values

   var printCount: Int=0

roomdb says does not know about printCount The columns returned by the query does not have the fields [printCount]

Answer 1

Every property in your data class has to have @ColumnInfo annotation, check this for more information
