Unused attributes of ShoppingCart and ShoppingCartItem

[Suraj Khurana]

Hi Devs,

I am curious about some protected data members of ShoppingCartItem and
ShoppingCart class.
ShoppingCartItem contains:



*private Map<String, String> orderItemAttributes = null;private Map<String,
Object> attributes = null;*
While ShoppingCart have:

*private Map<String, String> orderAttributes = FastMap.newInstance();*
*private Map<String, Object> attributes = FastMap.newInstance();*

I think orderAttributes and orderItemAttributes are pretty clear by the
name itself, what is the actual use of *attributes* data member for each
class.

Can this be removed and replaced with orderAttribute or orderItemAttribute
itself?

+1 Suraj,
If value of 'attributes' is not getting populated in DB then it should be
replaced.

I think purpose of attributes is different, if you want to set some custom
attribute to implement custom flow so you can use attribute.
These attribute value can be store in any entity or can be used to perform
business logic implementation as well.

Like in case of ShoppingCartItem, we set fromInventoryItemId as item
attribute and while creation order item we copy this field to
OrderItem.fromInventoryItem.

And if you want to store attribute in order or item level then you use
orderAttributes or orderItemAttributes.

Thanks & Regards

Yes indeed, Deepak.

Some additional infos:

* With the definition of ShoppingCartItem.attributeNames you are able to get context entries auto added to the „attributes“ Map within ShoppingCartHelper.addToCart. Such attributes may than be used, as described by Deepak, to be persisted anywhere or to just influence the checkout process. Those attributes are not necessarily to be persistet, they may be temporarily attributes like tokens or else just for the current checkout logic.

* The automatic adding of orderItemAttributes is controlled by the order.properties property „order.item.attr.prefix“. All context entries with this prefix (e.g. from an addToCart form) get added to the orderItemAttributes by ShoppingCartHelper.addToCart method.

* It is also possible to distinguish cart items by different attribute (and orderItemAttribute) values because of their relevance within the ShoppingCartItem.equals method

In my opinion the attribute maps differ fairly from the straightly domain model orderAttribute/orderItemAttribute ones and are not obsolete.
