Problem:
- /api/nutrition/weekly crashed with 500 Internal Server Error
- TypeError: strptime() argument 1 must be str, not datetime.date
Root Cause:
- d['date'] from PostgreSQL is already datetime.date object
- datetime.strptime() expects string input
- Line 156: wk=datetime.strptime(d['date'],'%Y-%m-%d').strftime('%Y-W%V')
Solution:
- Added type check before strptime()
- If date already has strftime method → use directly
- Else → parse as string first
- Works with both datetime.date objects and strings
Tested:
- /nutrition page loads without error
- Weekly aggregation works correctly
- Chart displays nutrition data
