【问题描述】:
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 时遇到 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)

is_staff = models.BooleanField(default=False)
is_active = models.BooleanField(default=True)
.....
class country(models.Model):
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)),

('state', models.ForeignKey(blank=True, null=True, on_delete=django.db.models.deletion.CASCADE, to='common.state')),

我在这里错过了什么?
【问题讨论】:
-
为什么您认为是用户模型导致了问题?你也可以展示你的国家模型吗?另外,这两个模型都在同一个 django 应用程序中吗?
-
@MananMehta 嘿,因为这个:正在应用 profile.0001_initial 。使用 sqlite 开发服务器在本地一切正常。这只发生在我使用 psycopg2 时。但我也添加了国家模式
-
@AndreMendes 你试过我在答案中建议的吗?
