没有这样的桌子:安排运动员举重

django-models django python

migrations.CreateModel(
    name='PlayerWeightLifting',
    fields=[
        ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
        ('time', models.IntegerField(default=-1)),
        ('medal', models.CharField(blank=True, choices=[('GOLD', 'GOLD'), ('SILVER', 'SILVER'), ('BRONZE', 'BRONZE'), ('FOURTH', 'FOURTH')], max_length=256)),
        ('player', models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='Schedule.Player')),
    ],
    options={
        'ordering': ['time'],
    },
),

这是我的模型 运动员举重 来自0001_initial.py文件。但当我运行它时,它显示“没有这样的表:时间表\运动员举重”,下面是我的对应模型:

class PlayerWeightLifting(models.Model):
    player = models.ForeignKey(Player, on_delete=models.CASCADE)
    weightlifting = models.ForeignKey(WeightLifting, on_delete=models.CASCADE, default='')
    time = models.IntegerField(default=-1)
    medal = models.CharField(max_length=256,blank=True, choices=MEDAL_CHOICES)

    def __str__(self):
        return str(self.weightlifting) + str(" ") + str(self.player)

    class Meta:
        ordering = ['time']

我有另一个类似类型的模型类,它工作正常,我被困在这个数据库中。帮助我!

这是admin.py中的部分:

admin.site.register(PlayerWeightLifting)

运行时终端上没有显示任何类型的错误 python manage.py生成迁移 和 python manage.py迁移 命令,但当我打开admin时,它只是显示,没有这样的表,可能的原因是什么?我甚至试过 python manage.py migrate--运行syncdb 任何帮助都将不胜感激!谢谢:)
