Hello, <br><br>I have posted this message to the gepaid mailing list but nobody answered yet, so I thought I would give a try on this mailing list, as this issue is also related to Zope 3.<br><br>Basically I have a fork of PloneGetPaid and did I am doing some major modification in it to adapt it to my business domain and requirements.<br>
<br>In my modified version of PGP, the ShippingMethod and
PaymentProcessor are not configured Store-wide, instead, they are
configured per PayableItem. When a user creates a new payableitem
(which in this particular framework is actually a custom content type
and not regular content types marked by interfaces) the user can choose
what Shipping Method and Payment Processor to use for this particular
item. They are named adapters and I store their names in the object.<br>
<br>What I would like to do (and have been trying to do without
success) is to have the checkout forms be generated according to
"metadata" defined on both the IShippingMethod and IPaymentMethod
adapters.<br><br>
<br>When the user chooses to buy a PayableItem, it goes straight to the
checkout process (the checkout view is called in the payable item's
view instead of the portal root). In the checkout-review-pay form's
__init__ method, both named adapters are instantiated (using
component.getAdapter(context,IShipphingMethod,name=context.getShipping_method()).<br>
<br>There's a particular ShippingMethod that doesn't require any fields
(only has some logic that is ran when the order is paid) . For this, I
would like to show a warning in the form (arbitrary HTML) instead of
fields, something like:<br>
<br>"This product will be installed by our team, we will contact you with details"<br><br>The User contact info and address are queried from the user model.<br><br>Also for the PaymentProcessor, different payment processor require different fields or interface elements. <br>
<br>My idea is to transfer the code that define, create and register
the Transient bags, the code that define the fieldsets and widgets all
to these adapters (IShippingMethod and IPaymentProcessor).<br><br>However,
I'm not sure yet on what to use to implement it. I thought on using
viewlets, since it would add another layer of abstraction and allow me
to insert html in them.<br>
<br>Please, I really need some help here, what do you experienced getpaid developers think I should do in order to achieve this?<br><br>I think that this idea could make into a good featureset for future getpaid releases!<br>
<br>Thanks,<br><font color="#888888"><br>Marcelo.</font>
