2. Original idea: GrocR
• Allow users to monitor stores for items that
are purchased periodically (like buying milk
once a week)
• User would be informed of the best deals on
their groceries
• Make comparison shopping automatic

3. Data relationships
• One or more users could
maintain a list of items
and an email address for
notifications
• A list contain 0 or more
items
• An item is a product
(SKU) as well as a
purchase interval and a
quantity
• A product contains basic
product information
• A store contains a list of
products, and a set of
store locations
• A store location gives the
address for a store
• Products would be filled
up by searches to an
external API containing
pricing data

4. Would have been a great idea!
• Except we couldn’t find an API that reliably gave out pricing
information.
• SupermarketAPI.com claims to perform this service.
• Unfortunately, it doesn’t.

5. Refactoring the concept: WishE
Refactored the user, list, list_item and product
models to support an application that can
maintain a list of products on an E-commerce
site
New user story: allow an E-commerce site user
to maintain a list of items as a wishlist

6. A refactored data model
• A product list contains
info about a product
available in the store
• Admins can CRUD
products in the store
• Standard users maintain
a list of items.
• Each item in the list is a
product
Relationships:
• User has one List
• A list may have many
products
• A product may be a
member of many lists

7. A clear data model made it EASY to
divide up work
• Alpha implemented Lists and List items
• Alec implemented Users and the overall UI
design
• Mike implemented Products and seed data

8. Here’s a demo!

9. Issues we ran into
(besides having our idea squashed by crappy APIs)

10. Gems we used

11. Future work
