This commit adds new guidelines for FastAPI and Vue.js development, emphasizing best practices for component structure, API performance, and data handling. It also introduces caching mechanisms using Redis for improved performance and updates the API structure to streamline authentication and user management. Additionally, new endpoints for categories and time entries are implemented, enhancing the overall functionality of the application.
Backend:
- Added `SettlementActivity` model to track payments against specific expense shares.
- Added `status` and `paid_at` to `ExpenseSplit` model.
- Added `overall_settlement_status` to `Expense` model.
- Implemented CRUD for `SettlementActivity`, including logic to update parent expense/split statuses.
- Updated `Expense` CRUD to initialize new status fields.
- Defined Pydantic schemas for `SettlementActivity` and updated `Expense/ExpenseSplit` schemas.
- Exposed API endpoints for creating/listing settlement activities and settling shares.
- Adjusted group balance summary logic to include settlement activities.
- Added comprehensive backend unit and API tests for new functionality.
Frontend (Foundation & TODOs due to my current capabilities):
- Created TypeScript interfaces for all new/updated models.
- Set up `listDetailStore.ts` with an action to handle `settleExpenseSplit` (API call is a placeholder) and refresh data.
- Created `SettleShareModal.vue` component for payment confirmation.
- Added unit tests for the new modal and store logic.
- Updated `ListDetailPage.vue` to display detailed expense/share statuses and settlement activities.
- `mitlist_doc.md` updated to reflect all backend changes and current frontend status.
- A `TODO.md` (implicitly within `mitlist_doc.md`'s new section) outlines necessary manual frontend integrations for `api.ts` and `ListDetailPage.vue` to complete the 'Settle Share' UI flow.
This set of changes provides the core backend infrastructure for precise expense share tracking and settlement, and lays the groundwork for full frontend integration.
