Question

使用Django 1.9.1并使用托管Postgres db（版本9.4.5）的Vagrant VM（Debian / Jessie64）进行测试。

我已经开始草绘我的模型并且网站运行正常 - 通过Admin界面添加记录很好等，但每次我尝试运行最基本的测试时，我收到以下错误：< / p>

django.db.utils.ProgrammingError: relation "contacts_person" does not exist
LINE 1: ...ion_id", "contacts_person"."directed_person" FROM "contacts_...

models.py：

class Person(models.Model):

    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=50)
    organisation = models.ForeignKey('contacts.Organisation', on_delete=models.CASCADE, null=True, blank=True)
    directed_person = models.BooleanField(default=True)

    def __str__(self):
        return '%s %s'% (self.first_name, self.last_name)


class Mode(models.Model):

    mode = models.CharField(max_length=50, blank=False)

    def __str__(self):
        return self.mode


class OrgType(models.Model):

    type = models.CharField(max_length=15)
    mode = models.ForeignKey('contacts.Mode', on_delete=models.CASCADE)

    def __str__(self):
        return self.type


class Organisation(models.Model):
    name = models.CharField(max_length=100, null=False)
    [--fields--]

    def __str__(self):
        return self.name

我在这个阶段的测试很简单：

class ModelCreationTests(TestCase):

    def setUp(self):
        Person.objects.create(first_name='Kimo', last_name='Rance', organisation=1, directed_person=True)
        Organisation.objects.create(
        name = 'Orgname',
        type = 'Orgtype',
        [--fields, etc--]
    )

    def test_is_a_person(self):
        p = Person()
        self.assertIsInstance(p, Person)

我已经看到Googling对此的历史引用表明它可能是早期版本的Django中的一个错误，特别是对于PostgreSQL，但似乎找不到合理的解决方案。任何进一步的帮助非常感谢。

包含来自./manage.py的输出--verbosity = 2 在knbk评论之后：

在向模型添加字段时尝试时类似。似乎不是问题。
