The option to choose between shipping methods

[Uznick]

Is there such option in Plata?

I've grepped through the code, and found a field "shipping_method" in the Order model, but I did not find where it is set.

The use case is simple: the user can choose between several shipping methods with different costs, and after that, the costs are added to the bill.

While Plata does come with the infrastructure to plug in your own shipping backends, it's not of very much help. It definitely is possible, but there's some work involved.

What you have to do is this:

• Modify a form in the checkout process to ask for the shipping method. For example, extend the discounts form with a shipping method radio button. Store the shipping method in the shipping_method field.
• Write your own order processor (take a look at plata/shop/processors.py, especially the FixedAmountShippingProcessor) which sets the shipping costs depending on the selected method.
• Define PLATA_ORDER_PROCESSORS, and replace the default shipping processor by your own.

That's it! Just ask if you have additional questions or need some guidance.

Thanks!

And can I modify a form in the checkout process? It's not pluggable, as I can see.

Just override the /shop/checkout/ url with my own view and do there what ever i need?

The official way would be to subclass the plata.shop.views.Shop class, override a few methods (for example discounts_form or checkout_form), and use this instead of the standard Shop class for inclusion into the URLconf.

class MyShop(Shop):
    def checkout_form(...):
        # return XYzzyForm

shop_views = MyShop(Order, ...)

urlpatterns = patterns(
    urL(r'^shop/', include(shop_views.urls)),
)

Hope it helps!

I was solving just that, you can found it here: https://github.com/Draciinfo/calendar-eshop/blob/master/calendareshop/shopping/forms.py Go for shopping.views.py for view implementation.
