At first glance this seems like a pretty good approach.

[mezzanine-users] Re: Cartridge creating a product with a user defined price

2014-11-21 Thread Josh B 
Sorry, was traveling and missed your message. What you will need to do is 
create either a view or a page processor 
(http://mezzanine.jupo.org/docs/content-architecture.html#page-processors) 
to post your new form to. Code samples below.

Here is my form:

  {% csrf_token %}
  
  
  
  Donate Now


Form processing code:
from .utils import Donation

if request.method == "POST" and form.is_valid():
  product = Product.objects.get(id=request.POST.get("product_id"))
  item = Donation(product, 
float(request.POST.get("donation_amount","0.0")) )
  request.cart.add_item(item, 1)

Utils
class Donation(object):
def __init__(self, product, unit_price, buyers_group):
product_variation = product.variations.all()
self.description = product.title
self.unit_price = unit_price
self.url = product.get_absolute_url()
self.sku = product_variation[0].sku
self.product = product
self.image = product_variation[0].image
self.buyers_group = buyers_group

def price(self):
  return self.unit_price 

def __unicode__(self):
return self.description

 Hey Josh,

 I also would like to implement donation driven products.
 Do you still stay with this approach or have you found a better 
 solution?

Hallo,

I still don't know really how to start.
Is the implementation similar to what Josh Cartmell describes in his Blog 
Collecting 
additional information on a per product basis in Cartridge 

?

I still don't know really how to start.
Is the implementation similar to what Josh C discuss in his Blog Storing 
custom fields on OrderItem 

?
