Files Modified

src/vitals/core/models.py

Added two new dataclasses:

@dataclass
class User:
    """用户档案"""
    id: Optional[int] = None
    name: str = ""
    created_at: datetime = field(default_factory=datetime.now)
    is_active: bool = False

@dataclass
class DataClearRequest:
    """数据清除请求"""
    user_id: int = 0
    mode: str = "all"  # "range" | "type" | "all"
    date_from: Optional[date] = None
    date_to: Optional[date] = None
    data_types: Optional[list] = None

src/vitals/core/database.py

Critical Fix - init_db(): Added user_id INTEGER DEFAULT 1 to all data tables:

• Line 38-52: Exercise table
• Line 58-72: Meal table
• Line 75-87: Sleep table
• Line 91-101: Weight table

Added user management functions:

• add_user(), get_users(), get_user(), update_user(), delete_user()
• set_active_user(), get_active_user()
• ensure_default_user() - migration function

Added data management functions:

• preview_delete() - preview deletion counts
• clear_data() - execute data deletion

Modified functions to support user_id parameter:

• add_exercise(), add_meal(), add_sleep(), add_weight()
• get_exercises(), get_meals(), get_sleep_records(), get_weight_records()

tests/test_models.py

Added test classes:

• TestUser (2 tests)
• TestDataClearRequest (3 tests)

src/vitals/web/app.py

Added imports (line 15):

from ..core.models import Exercise, Meal, Sleep, UserConfig, Weight, User

Added Pydantic models (lines 192-224):

• UserResponse - API response format for user data
• UserInput - API input validation for user creation/update
• DataClearInput - API input validation for data clearing

Added User Management API (lines 885-998):

• GET /api/users - Get all users
• GET /api/users/active - Get currently active user
• GET /api/users/{user_id} - Get specific user
• POST /api/users - Create new user
• PUT /api/users/{user_id} - Update user information
• DELETE /api/users/{user_id} - Delete user
• POST /api/users/{user_id}/activate - Set active user

Added Data Clear API (lines 1004-1049):

• POST /api/data/preview-delete - Preview deletion counts
• POST /api/data/clear - Execute data deletion

Updated GET endpoints for multi-user (added active_user check):

• /api/today (lines 304-319)
• /api/week (lines 327-350)
• /api/exercises (lines 469-502)
• /api/exercises/stats (lines 505-532)
• /api/meals (lines 541-569)
• /api/meals/nutrition (lines 572-601)
• /api/sleep (lines 694-722)
• /api/weight (lines 731-759)

Updated POST endpoints for multi-user (added active_user check):

• /api/exercise (lines 577-608)
• /api/meal (lines 611-662)
• /api/sleep (lines 775-801)
• /api/weight (lines 804-825)

Added Settings Page (Task 9) (line 3642):

• get_settings_page_html() - Complete settings page with 3 sections:
  • 系统设置: Theme toggle, font size controls, notification preferences
  • 用户管理: User list with add/switch/delete functionality
  • 数据管理: Preview-before-delete with date range and data type filters
• 853 lines of HTML/CSS/JavaScript with beautiful UI design
• Modern design with gradients, animations, responsive layout
• Real-time user management with AJAX API calls
• Comprehensive data clearing with preview counts

Added Settings Route (Task 9) (lines 288-291):

@app.get("/settings")
async def settings_page():
    """设置页面"""
    return HTMLResponse(content=get_settings_page_html(), status_code=200)

Updated Navigation Bars (Task 10) - Added settings link to 6 pages:

1. Home page (line 1278-1285) - Added <a href="/settings">设置</a>
2. Exercise page (line 1736-1743) - Added settings link
3. Meal page (line 2280-2289) - Added settings link
4. Sleep page (line 2897-2907) - Added settings link
5. Weight page (line 3309-3316) - Added settings link
6. Report page (line 3575-3582) - Added settings link

tests/test_models.py

Added test classes:

• TestUser (2 tests)
• TestDataClearRequest (3 tests)

tests/test_database.py

Added test classes:

• TestUserDB (7 tests) ✅ All passed
• TestUserIdMigration (2 tests) ✅ All passed
• TestDataClear (6 tests) ✅ All passed

Issues & Solutions

Issue 1: Missing user_id Column

Error: sqlite3.OperationalError: table exercise has no column named user_id

Tests affected: 7 out of 8 tests failed in TestUserIdMigration and TestDataClear

Root cause: init_db() created tables without user_id column, but add_exercise(), add_meal(), etc. tried to INSERT with user_id

Solution: Modified init_db() to include user_id INTEGER DEFAULT 1 in CREATE TABLE statements for all four data tables (exercise, meal, sleep, weight)

Result: ✅ All 8 tests passed after fix

---

Architecture Decisions

1. Active User Pattern: Single-active-user model where all data operations automatically scope to the active user
2. Backward Compatibility: Used DEFAULT 1 for user_id to ensure existing data works without migration
3. Data Isolation: All GET/POST endpoints check for active user and include user_id in database operations
4. Migration Strategy: init_db() creates tables with user_id from the start; ensure_default_user() handles ALTER TABLE for existing databases
5. Test-Driven Development: Fixed database schema issues by running tests first, identifying failures, then fixing root cause

---

Next Steps

Task 9: Create Settings Page UI

1. Create /settings route in app.py
2. Apply ui-ux-pro-max design system
3. Implement sections:
   • User management (list, create, switch, delete)
   • System management (data clear with preview, export data)
4. Use existing API endpoints from Tasks 6-7

Task 10: Update Navigation

Add settings page entry to navigation on all pages:

• / (home)
• /exercise, /meal, /sleep, /weight
• /report

Task 11: Integration Tests

Run end-to-end tests to verify:

• Multi-user workflow
• Data isolation
• Settings page functionality

Current Status

✅ ALL TASKS COMPLETE (Tasks 1-11)

Backend: ✅ Complete (Tasks 1-8)

• Multi-user database schema with user_id columns
• User CRUD operations
• Data clearing functionality with preview
• Active user pattern implementation
• All data APIs updated for multi-user support

Frontend: ✅ Complete (Tasks 9-11)

• Settings page UI with beautiful design (Task 9) ✅
  • 853 lines of HTML/CSS/JavaScript
  • User management with real-time AJAX
  • Data clearing with preview functionality
  • Modern UI with gradients and animations
• Navigation updates across all 6 pages (Task 10) ✅
• Integration tests completed (Task 11) ✅
