Issue with PloneGetPaid portlet not displaying correct price

[duffyd]

Hi,

As part of my pay-for-subscription package I've just added an option to
specify an optional donation amount on subscription. In order to
implement this I modify the item.cost post the creation of the line
item. To help visualise things a bit better, the relevant code is as
follows:

<code>
        cart_util = getUtility(IShoppingCartUtility)
        cart = cart_util.get(self.context, create=True)
        itemfactory = getMultiAdapter((cart, buyablemember),
ILineItemFactory)
        if itemfactory:
            item = itemfactory.create()
            # Override the item name as
            # its currently the members name
            item.name = buyablemember.subscription_level()
            # Add the optional donation amount
            if buyablemember.getDonationAmount() != 0.0:
                item.cost = item.cost +
buyablemember.getDonationAmount()
            cart.__delitem__(item.item_id)
            cart[item.item_id] = item
</code>

Now this works as far as the item.cost gets incremented and the
generated PayPal button displays the correct price but the PloneGetPaid
portlet is still displaying the old price (prior to incrementing it). Do
I need to reindex a catalog or something?

Thanks,
Tim

The portlet takes it's price from the content item the marker interface is on, not the item.  So if you want to have the portlet show that price you will either need to modify the price on the associated buyable (probably not a good idea since that will change the price for everyone).  Or override the default portlet so it has new logic and can look up it's price from the cart if it exists.

Anyway is there a reason memberships have their own associated donation?  Why not create two line items, one for the membership and the other a VariableDonationAmount line item if the user chooses to also donate.
