1.2. Component Diagram

Architectural overview

We use an MVC architecture where each component is, for the most part, directly mapped to a Django "app".

Module descriptions

1. Authentication: Handles the sign-up, login, logout, and session.
2. Recipes: Generates and displays recipes and their corresponding images.
3. Kitchen: Creates ingredients and reminds user to update it.
4. Statistics: Generates and shows a report.
5. User: Handles editing and deleting accounts.

What changed

No changes.

1.3. Data Model

What changed

1. Fixed the relationship between Ingredient.user_id and User.id (was User.username).
2. Removed the fields first_name, last_name, is_staff, is_active, is_superuser, date_joined from the User table as they were not that important to represent our system, but they still exist as fields in Django's default User model.
3. Removed the fields unit_count and measurement_unit from the Ingredient table.
