python - 迁移时出错 - psycopg2 Django

Question

我正在尝试在服务器上部署本地工作，但是当我在 python manage.py 上运行 migrate 时我遇到了 psycopg2 问题。

设置:

    DATABASES = {
    'default':{
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': '******',
        'USER': '*****',
        'PASSWORD': '**********',
        'HOST': '*******',
        'PORT': '5432'
    }
}

有问题的模型

class user(AbstractBaseUser, PermissionsMixin):
   created = models.DateTimeField(auto_now_add=True)
   first_name = models.CharField(max_length=50)
   last_name = models.CharField(max_length=50)
   email = models.EmailField(unique=True)
   street = models.CharField(max_length=100, null=True, blank=True)
   street_num = models.CharField(max_length=10, null=True, blank=True)
   unit_num = models.CharField(max_length=10, null=True, blank=True)
   city = models.CharField(max_length=50, null=True, blank=True)
   postal_code = models.CharField(max_length=10, null=True, blank=True)
   state = models.ForeignKey(state, null=True, blank=True)
   country = models.ForeignKey(country, null=True, blank=True)
   phone = models.CharField(max_length=50, null=True, blank=True)

   is_staff = models.BooleanField(default=False)
   is_active = models.BooleanField(default=True)
   .....

class country(models.Model):
    name = models.CharField(max_length=50)
    code = models.CharField(max_length=10)


class State(models.Model):
    country = models.ForeignKey(country, on_delete=models.CASCADE)
    name = models.CharField(max_length=50)
    short_name = models.CharField(max_length=3)
    group = models.CharField(max_length=2, null=True, blank=True, choices=GROUP_TYPE)
    properties = models.ForeignKey(stateProperties, null=True, blank=True)

迁移文件:...

            ('brand', models.CharField(blank=True, max_length=30, null=True)),
            ('exp_month', models.CharField(blank=True, max_length=2, null=True)),
            ('exp_year', models.CharField(blank=True, max_length=2, null=True)),
            ('country', models.ForeignKey(blank=True, null=True, on_delete=django.db.models.deletion.CASCADE, to='common.country')),
            ('groups', models.ManyToManyField(blank=True, help_text='The groups this user belongs to. A user will get all permissions granted to each of their groups.', related_name='user_set', related_query_name='user', to='auth.Group', verbose_name='groups')),
            ('state', models.ForeignKey(blank=True, null=True, on_delete=django.db.models.deletion.CASCADE, to='common.state')),

.....

**django.db.utils.ProgrammingError: relation "common_country" does not exist**

我在这里错过了什么？

我发现了问题。这是我的错误。我有一个 .gitignore 设置为忽略迁移文件和文件夹。所以Country所在的migration文件夹没有被发送到master分支。

它是固定的。感谢您的帮助。
