I am struggling removing all related entries to a parent in a 1:n relationship. In the client order example this would be removing all orders of a customer. If I understand correctly, I cannot removeAll because this would remove also the orders of all other customers.

I also don’t get this answer running. The _queryBuilder.backlink(... (see 2nd snippet) throws:

The argument type ‘QueryRelationToOne<Order, Customer>’ can’t be assigned to the parameter type ‘QueryRelationToOne<Order, Order>’.

@Entity()
class Customer {
  int id;
  @Backlink('customer')
  final orders = ToMany<Order>();
}
@Entity()
class Order {
  int id;
  final customer = ToOne<Customer>();
}

final QueryBuilder<Order> _queryBuilder = myBox.query();
_queryBuilder.backlink(Order_.customer, Order_.customer.equals(id));
