PriceComparator is a Django tool to compare prices from merchant API endpoints. The project was constructed in one week and represents my first experience with Django. This project uses a Merchants app that mocks the endpoints and a UPCs app that compares the prices and returns the first merchant URL with the lowest price.
PriceComparator is not currently built into an executable. As such, The following command can be used to run the test environment:
python manage.py runserver
In a browser window, the following URL will run a price comparison on some of the mockup data:
Where <upc> is one of the following:
- 12345
- 56789
- 00000
- 11111
Each of these UPCs represents a manual test case that provides the calling function with a JsonResponse that is unique to each merchant and parsed by a merchant-specific parser.
- Easily add a merchant by adding the data to the Merchant model in the admin interface at http://localhost:8000/admin then implementing the appropriate parser in
upcs/parsers.py - The Merchant app simulates several vendor endpoints, as outlined above.
- The Upc app analyzes responses from the Merchant app and provides the first merchant URL with the lowest price and item in stock.
