Hi Greg,
Does it mean that there is no relationship from Offering to Item?
Is it worth adding (and maintaining so that they are always at sync)?
I meant to add the relationship on the other side ;)
Sorry, I misunderstood.
Since I do not have a unique
Offering instance per
ShoppingCartItem,
Offering cannot have a
ShoppingCartItem property.
Currently,
ShoppingCartItem has:
@OneToOne(optional=false)
private Offering offering;
And I have nothing specified at the
Offering end. Is there a
better way to model this?
Thanks!
Greg

Hi,
I have a method that removes a persistent object from a collection
based on a property of the object being removed, like so:
/**
* Removes all ShoppingCartItems containing this
* offering
*/
public void removeItem(Offering offering)
{
List<ShoppingCartItem> iList = new
ArrayList<ShoppingCartItem>(getItems());
for(ShoppingCartItem i : iList)
{
if(i.getOffering().equals(offering))
{
getItems().remove(i);
}
}
}
Is this the best way to do this?
Cheers,
Greg
p.s.: I'm so glad I found this list. I feel like I've been groping in
the dark with JPA. Thanks for all the help! --G
