Missing Table When Running Django Unittest with Sqlite3
我已经查看了这篇文章，并且正在尝试设置我的项目进行测试。每当我尝试运行任何数据库命令时，我都会收到错误消息。我遇到的问题是当我尝试执行manage.py syncdb时，我得到一个数据库错误，表示即使它当前在模型文件和生产数据库中也没有这样的表。
这是追溯。

这是在我的settings.py文件中
if 'test' in sys.argv or 'jenkins' in sys.argv:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'test_ndptc'
}
}
如果我将上面的if语句设置为true并尝试运行manage.py syncdb，也会出现同样的错误。
以下是造成问题的模型。

我也有这个问题。原来我必须在settings.py文件中添加TEST_NAME属性才能正确识别测试数据库。它解决了我的问题：
if 'test' in sys.argv:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(os.path.dirname(__file__), 'test.db'),
'TEST_NAME': os.path.join(os.path.dirname(__file__), 'test.db'),
}
}
答案 1 :(得分：0)
对于具有单元测试的db NAME，我建议始终使用“：memory：”。我曾经错误地指定了一个实际的数据库路径，我的单元测试需要45分钟才能运行。当我指定“：memory：”时，它们在不到一分钟的时间内运行。
if 'test' in sys.argv:
DATABASES = {
'default':{
'ENGINE': 'django.db.backends.sqlite3',
'NAME': ':memory:',
'TEST_NAME': ':memory:',
},
}
