Creating an online shop project

We are going to start with a new Django project to build an online shop. Our users will be able to browse through a product catalog and add products to a shopping cart. Finally, they will be able to check out the cart and place an order. This chapter will cover the following functionalities of an online shop:

  • Creating the product catalog models, adding them to the administration site, and building the basic views to display the catalog
  • Building a shopping cart system using Django sessions to allow users to keep selected products while they browse the site
  • Creating the form and functionality to place orders on the site
  • Sending an asynchronous email confirmation to users when they place an order

Open a shell, create a virtual environment for the new project, and activate it with the following commands:

mkdir env
virtualenv env/myshop
source env/myshop...
