Summary

We've been implementing KeinaSystem, an agricultural management system with Django/Next.js and Docker:
Completed:
- Day 1-2: Docker setup, Django configuration (REST, JWT, CORS, PostGIS, Japan timezone)
- Day 3: Data models (OfficialKyosaiField, OfficialChusankanField, Field with ManyToMany, Crop, Variety, Plan)
- Day 4: Import API endpoints for ODS files
- Day 5: init_crops command, serializers, ViewSets, summary/copy APIs
Current Issue:
- Day 6: PDF generation (/api/reports/kyosai/2025/) is returning HTTP 500 error
Next Step:
Debug the PDF generation error by checking backend container logs to see the specific exception.
Want me to check the container logs to diagnose the PDF 500 error?
