OperationalError, no such column. Django（30个答案）

嘿，伙计们，我的工作与django框架，我有错误OperationalError.
我有两个具有相同字段的类：

class Student(models.Model):
    user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE)
    id = models.AutoField(primary_key=True)
    First_Name = models.CharField('First Name', max_length=30, null=True, blank=True)
    Last_Name = models.CharField('Last Name', max_length=30, null=True, blank=True)
    ID_Number = models.CharField('Id Number', max_length=30, null=True, blank=True)
    Phone = PhoneNumberField('Phone',null=True)
    
    class Meta:
        verbose_name_plural = "Students"

    def __str__(self):
        return str(self.user)

class Lecturer(models.Model):
    user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE)
    id = models.AutoField(primary_key=True)
    First_Name = models.CharField('First Name', max_length=30, null=True, blank=True)
    Last_Name = models.CharField('Last Name', max_length=30, null=True, blank=True)
    ID_Number = models.CharField('Id Number', max_length=30, null=True, blank=True)
    Phone = PhoneNumberField('Phone',null=True)
    
    class Meta:
        verbose_name_plural = "Lecturers"

    def __str__(self):
        return str(self.user)

我为Student和Lecturer类添加了一个新字段，该字段为

Phone = PhoneNumberField('Phone',null=True)

是的，我做了命令：

python manage.py makemigrations 
python manage.py migrate

在那之后我确信一切都更新了：

Operations to perform:
    Apply all migrations: HomePage, accounts, admin, auth, contenttypes, sessions
Running migrations:
    No migrations to apply.

但是当我运行 runserver 时，我会转到管理路径：

添加我去讲师数据一切工作都很好我有新的领域电话：

但是，当我尝试转到学生数据时，我收到一个错误，无法识别字段的电话！
