Re: How to extract a number from a url

[Pankaj Kumar]

Try using regular expression  (?P[0-9]+)
 similar to this:

url(r'^music/(?P[0-9]+)/newsongs$', views.your_view_function())


cheers!

RE: Best way to structure this Django project

[Pankaj Kumar]

Thats a valid workflow in my opinion. Many Django works take that approach.

But alternatively, if you want you can pass the product info as parameters
in the Payment app while redirecting and can have a model in the Payment
app to capture and integrate product and payment parameters together. That
way you can avoid importing the Product model but retaining the product
informations along with payment informations.
