Week 8 Worklog

Week 8 Objectives:

  • Backend: Build the complete Food & Nutrition module — Food, Meal, MealFood, DailyNutrition with auto-calculated macro nutrients.
  • Frontend: Build the DietScreen with today’s 4-meal layout, food search modal, and add-food-to-meal flow; plus DietHistoryScreen.
  • Enable users to track daily calorie and macro intake across all meal types.

Tasks to be carried out this week:

Day Task Start Date Completion Date Reference Material
2 - Build Food entity (table food)
  + Fields: name, caloriesPer100g, proteinPer100g, carbsPer100g, fatsPer100g, unit
  + FoodController (/api/foods): POST /, GET /{id}, GET / (paginated), GET /search?keyword=, PUT /{id}		 03/03/2026 03/03/2026
3 - Build Meal entity (table meal)

4 - Build MealFood entity (table meal_food) — join table with computed macros
  + Fields: meal (@ManyToOne), food (@ManyToOne), quantity (float grams)
  + calories, protein, carbs, fats auto-calculated at insertion from Food’s per-100g values × (quantity/100)
  + MealFoodController (/api/meal-foods): add food to meal, list foods in meal, remove		 03/05/2026 03/05/2026
4 - Build DailyNutrition entity (table daily_nutrition)
  + Fields: nutritionDate (LocalDate), totalCalories, totalProtein, totalCarbs, totalFats
  + DailyNutritionController (/api/daily-nutrition): POST /calculate?date= recomputes & saves daily totals; GET /?date= retrieves		 03/05/2026 03/05/2026
5 - Build DietScreen (Frontend)
  + Display today’s 4 meals (Breakfast/Lunch/Snack/Dinner) via ensureDailyMeals
  + Each meal: food items list, calorie count, progress bar vs. target
  + “Add food” modal: search by name (searchFoods), input quantity in grams, submit → addFoodToMeal
  + Total daily calorie progress bar at top
  + Pull-to-refresh		 03/06/2026 03/06/2026
6 - Build DietHistoryScreen (Frontend)
  + Monthly calendar view — tap a date to see that day’s meal breakdown
  + Per-meal food items with calorie totals
- Integrate foodService: getMealsByUser, getMealFoodsByMealId, addFoodToMeal, deleteMealFood into DietScreen
- Test full nutrition tracking loop: add food → view nutrient breakdown → track daily total		 03/07/2026 03/07/2026

Week 8 Achievements:

  • Backend — Food & Nutrition module:
    • Food entity seeded with real food data from the fitness_crawler tool (over 100 food items in local DB).
    • MealFood correctly auto-calculates calories, protein, carbs, fats on insertion based on quantity / 100 * per100gValue.
    • POST /api/daily-nutrition/calculate?date= aggregates all MealFood entries for a date into a single DailyNutrition record.
    • Pagination on GET /api/foods works — PageResponse<T> wrapper handles page, size, totalPages, totalElements.
    • Keyword search on GET /api/foods/search?keyword= performs case-insensitive LIKE query.
  • Frontend — Diet tracking:
    • DietScreen correctly calls ensureDailyMeals to guarantee 4 meal slots exist for today.
    • Food search modal shows paginated results with lazy loading.
    • Adding food: quantity input → backend calculates and stores macros → UI refreshes with updated totals.
    • DietHistoryScreen calendar correctly loads meal data for selected dates.
    • Daily calorie progress bar reflects totalCalories / 2500 target accurately.

Next Week Plan:

  • Backend: Build the User Metric module — BodyMetric entity and HealthCalculation with BMI / BMR / TDEE computation logic.
  • Frontend: Build HealthDashboardScreen with wheel pickers, BodyMetricListScreen, BodyMetricFormScreen, and all health chart components.
