我想在服务器上部署本地工作,但是当我运行python manage.py时,我遇到了psycopg2的问题。迁移时出错 - psycopg2 Django

设置:

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

模型有问题

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')), 

.....

我在这里错过了什么?

你为什么认为这是导致问题的用户模型?你能否展示你的国家模式?此外,都是在同一个Django应用程序中的模型? –

@MananMehta嘿,因为这个:申请profile.0001_initial。一切工作正常使用sqlite开发服务器本地。这只在使用psycopg2时才会发生。但即时通讯也添加国家模型 –

@AndreMendes你有没有尝试我在答案中提出的建议? –

  1. 评论国家模型和运行

python manage.py makemigrations app_name

  • 取消注释国家模型和运行相同的上述命令(国家模式将正确重新制作)

  • 最后将更改应用到DB使用迁移:

  • python manage.py migrate

    替换此:

    country = models.ForeignKey(country, null=True, blank=True) 
    

    有:

    country = models.ForeignKey(Country, null=True, blank=True) 
    

    而且应该这样做,我相信。

    对不起,我把全部改为小写,试图解决这个问题。我所有的模型都是小写字母。在所有模型都是大写之前。 –

    我发现了这个问题。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所在的迁移文件夹没有被发送到主分支。

    其固定。 thx寻求帮助。
