Mysql Django测试Django.db.utils.ProgrammingError:（1146，“Table'；db.Table'；不存在”）

我在Django中运行一个简单的测试用例，我有一个模型订阅服务器，但当我运行

python manage.py测试时

它给了我以下的错误

Creating test database for alias 'default'...

我的模型看起来像这样

from django.db import models

class Subscribers(models.Model):
    """ Subscriber Model """   
    idsubscribers = models.AutoField(primary_key=True)
    legalid = models.CharField(max_length=45, blank=True, null=True)
    name = models.CharField(max_length=45, blank=True, null=True)
    lastname = models.CharField(max_length=45, blank=True, null=True)
    initialdate = models.DateField(blank=True, null=True)
    bday = models.DateField(blank=True, null=True)
    email = models.CharField(max_length=100, blank=True, null=True)
    phone = models.CharField(max_length=45, blank=True, null=True)
    emergencyphone = models.CharField(max_length=45, blank=True, null=True)
    photolink = models.CharField(max_length=200, blank=True, null=True)
    medicalconditions = models.CharField(max_length=200, blank=True, null=True)
    objectives = models.CharField(max_length=200, blank=True, null=True)
    paymentfrequency = models.CharField(max_length=45, blank=True, null=True)

    def get_fullname(self):
        return self.name + " " + self.lastname
    class Meta:
        managed = False
        db_table = 'subscribers'

还有我的测试文件

from django.test import TransactionTestCase
from gatpulsecore.models import Subscribers

class SubscribersTest(TransactionTestCase):
    """ Test module for Subscribers model """

    def setUp(self):
        Subscribers.objects.create(
            legalid='34214555', name='Casper', lastname='Smith')
        Subscribers.objects.create(
            legalid='24612555', name='John', lastname='Rogers')

    def test_subscriber_fullname(self):
        """ Test method get_fullname """
        sub_casper = Subscribers.objects.get(name='Casper')
        sub_john = Subscribers.objects.get(name='John')
        self.assertEqual(
            sub_casper.get_fullname(), "Casper Smith")
        self.assertEqual(
            sub_john.get_fullname(), "John Rogers")

我已经尝试过迁移，但没有帮助，也有人建议使用TransactionTestCase而不是TestCase，但也不起作用。

有人遇到过同样的错误吗？我一直在寻找解决方法，但似乎没有找到任何有用的方法。

如果您使用多个数据库，则可能会发生这种情况，在这种情况下，您必须使用以下方法指定数据库：

MyModel.objects.using("database_name")

或者简单地将特定数据库指定为主数据库

据我所知，django没有检测到您的数据库，或者您有多个数据库。

我明白了，奇怪的是，我在settings.py中只注册了一个数据库，并且指定数据库都不起作用，谢谢
