我正在建立一個空數據庫（User和UserProfile表創建，但沒有填充），但是，我發現了以下錯誤：Django的loaddata唯一約束失敗
django.db.utils.IntegrityError: Problem installing fixture 'path/to/mydata.json': Could not load myapp.UserProfile(pk=1): UNIQUE constraint failed: myapp_userprofile.user_id
我檢查（甚至在運行此命令後）並且數據庫根本不被填充。那麼它怎麼會給出一個錯誤，即PK不是唯一的？
如果相關，UserProfile只是擴展了默認User模型與OneToOneField關係，建議here。
這裏是mydata.json包含：
