Overview

Online shop that's built using the following apps:

shop

• Contains category and product models, products relates to categories using OneToMany relation
• Supports list and detail views on products
• Recommends products for users
  • Redis is used to store products that are purchesed together
  • Each product assigned with a products set has a score
  • High score products are recommended if the products in cart is present in the set

Since only admins can add new products to the shop, Django's built in admin portal is used to add new products

cart

• Simple cart is used to manage users' products to proceed to payment
• Cart's data is saved in the session

Saving cart in session isn't a good way if multiple servers are used with a load balancer, storing it in a cache like redis would be better

order

• Contains order model, which stores users' info to proceed for payments
• Launches Celery async task that sends an email confirming order

payment

• Stripe is used as a gateway for payments

coupon

• Coupons can be added using Django's admin portal
• Each coupon has a code, discount percentage and end date
