24 If you try to insert a ‎`Book` with ‎`userOwnerId = 1` but there is no ‎`User` with ‎`userId = 1`, you will get this error. Summary Always insert parent rows before child rows. 25 fsefawfaw awfaw Use transactions for related inserts. Check your foreign key values and definitions. Consider ‎`onDelete = ForeignKey.CASCADE` if you want child rows to be deleted automatically when the parent is deleted. If you share your entity definitions and DAO code, I can give more specific advice.
