我有一个简单的模型类如下

class Language(models.Model):
    name= models.CharField(max_length=20)
    code= models.CharField(max_length=5)
    status=models.BooleanField()
    create_at=models.DateTimeField(auto_now_add=True)
    update_at=models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name

字符串
我想这样用它

llist = Language.objects.filter()
list1 = []
for rs in llist:
    list1.append((rs.code,rs.name))
langlist = (list1)

型
但是当我尝试使用llist时，它总是抛出这个错误：

return Database.Cursor.execute(self, query, params)
django.db.utils.OperationalError: no such table: home_language

型
我尝试使用python manage.py shell进行查询，它显示相同的上述错误。
这是完整的错误：

Traceback (most recent call last):
  File "C:\Users\Daisy\Downloads\Django-E-Commerce-master\env\lib\site-packages\django\db\backends\utils.py", line 86, in _execute
    return self.cursor.execute(sql, params)

    return Database.Cursor.execute(self, query, params)
sqlite3.OperationalError: no such table: home_language

The above exception was the direct cause of the following exception:
