Day 3 のデータモデル実装が完了しました。
完了内容 models.py fields/models.py: - OfficialKyosaiField - 共済マスタ - OfficialChusankanField - 中山間マスタ - Field - 圃場（PointField で位置情報対応） plans/models.py: - Crop - 作物マスタ - Variety - 品種マスタ（unique_together 制約） - Plan - 作付け計画（unique_together 制約） admin.py - 全てのモデルを admin に登録 - list_display, search_fields, list_filter 設定 - FieldAdmin は GIS 用 GISModelAdmin を使用 マイグレーション ✅ makemigrations - 成功 ✅ migrate - 成功 管理画面 (http://localhost:8000/admin) で全てのモデルが確認・編集できます。
