我正在建立一个空数据库（User和UserProfile表创建，但没有填充），但是，我发现了以下错误：Django的loaddata唯一约束失败
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
我检查（甚至在运行此命令后）并且数据库根本不被填充。那么它怎么会给出一个错误，即PK不是唯一的？
如果相关，UserProfile只是扩展了默认User模型与OneToOneField关系，建议here。
这里是mydata.json包含：
