Hi..
I'm having some problem with a many-to-many relationship.
I've two entities: Order and Product.
They have a many-to-many relationship, and an attribute: quantity.
The strange thing is that I don't see the OrderProduct model
generated...
Check the value of Class Name in the model. It's probably
EOGenericRecord. Change it to you.model.OrderProduct
You are right.. Now I see the class
Well.. to be honest I don't understand how many-to-many works...
(In WO.. I know the "DB-theory")...
OrderProduct orderProduct =
(OrderProduct)EOUtilities.createAndInsertInstance(ec,
OrderProduct.ENTITY_NAME);
// or
OrderProduct orderProduct = OrderProduct.createOrderProduct(ec,
product, order);
orderProduct.setQuantity(quantity);
ec.saveChanges();
Little problem.. the only method createOrderProduct has as arguments:
editingContext, quantity.
So.. I can't set it's pks.
What particular questions do you have?
with regards,
