django.db.utils.IntegrityError：FOREIGNKEY制約が失敗しました

私のmodels.py

ステータスモデルEDDIT

多分問題はここにあります。コメントで見ることができるいくつかのコードを追加した後、問題が発生します。「この最後のエラーは、pk = 1のステータスがすでに存在することを示していますが、前のエラーは反対を示しています。ステータスモデルを質問に追加してください。他に考慮すべき条件があるかどうかを確認してください。」：

class Status(models.Model):
    name = models.CharField(max_length = 16, blank=True, null=True, default=None)
    is_active = models.BooleanField(default=True)
    created = models.DateTimeField(auto_now_add=True, auto_now=False)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True)

    def __str__(self):
        return "Статус %s" % self.name
