Question

我正在尝试使用python的TestCase类编写测试用例。当我运行python manage.test时，出现以下错误：

这是我的tests.py：类TestCase（TestCase）：

@classmethod
def setUpTestData(cls):
    print("calling command")
    db_dump = “’file_data.json'"
    call_command("loaddata",db_dump,verbosity=3)


def test_statuscode(self ):
    print("Starting test cases....")
    url=‘/find_file/‘
    query_params ={'spec’:’detailed’,’name’:’ABV’}
    response = self.client.get(url,query_params)
    self.assertEqual(response.status_code,200)

这是files / models.py

class MyModel(models.Model):
spec = models.CharField(max_length=255, blank=True, null=True)
id = models.CharField(primary_key=True, max_length=128)
name = models.CharField(max_length=128, blank=True, null=True)
number = models.CharField(max_length=60, blank=True, null=True)
db = models.CharField(max_length=32)

class Meta:
    managed = True
    db_table = ‘mytable’

settings.py

from .base import *


DATABASES = {
   'default' :{
        'ENGINE' : 'django.db.backends.mysql',
        'NAME': ‘mydb_90',
        'USER': ‘xxx’,
        'PASSWORD': ‘yyy’,
        'PORT' : '3306',

   },
}

Django版本是2.0.6。 Python 3.7.1。我有两个问题： 1）为什么会出现此错误？迁移文件到位，日志显示已执行这些文件。 2）我曾期望在setupTestData方法中进行数据库和表的创建。看起来数据库和表是在调用此方法之前创建的。因此，我茫然不知如何调试它。

Django测试错误：django.db.utils.ProgrammingError：（1146，“表'test_mydb.mytable'不存在”）
