我正在学习Django测试。我编写了一个简单的应用程序,其中包含一个简单的模型,并希望运行测试以检查模型方法的有效性,但是在运行测试时出现错误消息。
以下是models.py的内容。
以下是models.py的内容。
from django.db import models
class Trip(models.Model):
origin = models.CharField(max_length=20)
destination = models.CharField(max_length=20)
def __str__(self):
return self.origin
def is_valid(self):
return self.origin != self.destination
这是test.py文件
from django.test import TestCase
from .models import Trip
# Create your tests here.
class TripModelTests(TestCase):
def test_trip(self):
a = Trip.objects.create(origin='a', destination='a')
self.assertIs(a.is_valid(), True)
以下是 settings.py 文件。
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'd57r9kcrhthdc7',
'USER': 'sdqxaruartlvrd',
'PASSWORD': 'e7b8f85611596ed125fe3ed4ea590f821f65e317c17ee7871be75b8130d72378',
'HOST': 'ec2-3-214-46-194.compute-1.amazonaws.com',
'PORT': '5432',
'TEST': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
}
}
}
执行 python manage.py test transport 时,我收到了以下错误信息:
Creating test database for alias 'default'...

如果我只使用默认的Django设置和sqlite数据库,测试就可以正常工作...
