Cart Item Problem

[Shereen]

Hi All
I'm having a problem related to how the objects are related to the database tables so that the object can be saved
This was very easy using minlang where you can specify what entity are you using and do the CRUDs easily
but what about the java objects how they are mapped to the database tables

I cam Across this problem while tring to do the following
I want to add two field in the OrderItem table those fields are called fromDate and toDate
I've added them to the database table through the entitymodel.xml very easily
Actually those two fields come from the quote like startReservation date for example
so I went to the service loadCartFromQuote
and added them into the cartItem Object
I don't know how to map this to the orderItem table
I mean now the cartItem contains 2 dates and the OrderItem has 2 dates how the mapping is done?
where the method that will save the cart item to order item and put it in the database?
I've searched for a while and I found that ofbiz doesn't use ORM then how it works?

I'd be grateful for a reply

as said many times there is not object mapping into database.
learn how delegator's work.
the beauty of ofbiz frame work is once you define a new field in a
entity it is available through the delegator, in any code. No need to map.

Thank a lot for your answer
I'm really lost in shopping cart classes
Could you please give me any guidelines how to study specifically the delegators used regarding the shopping cart
or generally how can I  get to learn this.
Things have been much easier when I used the minilang.
even sometimes when using the java I used to make genericValue objects specify the entity and make the CRUDs operations
but in case this cartItem objects hasn't been yet in the database so I'm missing this level.
I don't know where the part that corresponds to the part of GenericValue objects and these staff
can you provide me with any links or even files from the code itself to learn and understand thanks a lot

go over the training videos.
they explain entity engine and delegator.

Hi Shereen,

ShoppingCart.makeOrderItems(boolean, boolean, LocalDispatcher) is probably the method you are looking for.

Thanks Scott
It really worked with me and I like to share this so that other users can get benefits from that
so that anyone who would like to add something to the order item must study this method
Thanks scott Thanks freeman
