django - 克隆项目失败后运行迁移的 Django
问题描述
我刚刚从 git 存储库中克隆了我的项目。安装所有依赖项和虚拟环境后，我继续通过运行迁移来设置数据库，如下所示：
python3.6 manage.py makemigrations
python3.6 manage.py makemigrations api
python3.6 manage.py migrate
但最后一个命令失败：
python3.6 manage.py migrate
Operations to perform:
Apply all migrations: account, admin, api, auth, authtoken, contenttypes, sessions, sites, socialaccount
Running migrations:
Applying account.0001_initial...Traceback (most recent call last):

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError: no such table: users_user
这是我的模型：
kofiapi/api/products/models.py：
from django.db import models
import uuid
class Product(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
sku = models.CharField(unique=True, blank=False, max_length=13, help_text="Enter Product Stock Keeping Unit")
slug = models.SlugField(blank=True, unique=True)
name = models.CharField(blank=False, max_length=200, help_text="Enter Product Name")
short_description = models.CharField(max_length=350, help_text="Enter Product Short Description (350 characters)")
description = models.TextField(help_text="Enter Product Description")
image = models.ImageField(null=True, blank=True)
cost = models.FloatField(blank=False, help_text="Enter Product Cost")
def __str__(self):
return self.name
kofiapi/api/users/models.py：
import uuid
from django.db import models
from django.contrib.auth.models import AbstractUser
from django.utils.translation import ugettext_lazy as _
from django.conf import settings
class User(AbstractUser):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
username = models.CharField(max_length=120, blank=True, null=True)
email = models.EmailField(_('email address'), unique=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username', 'first_name', 'last_name']
def __str__(self):
return "{}".format(self.email)
class UserProfile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL,
on_delete=models.CASCADE,
related_name='profile')
dob = models.DateField()
phone = models.CharField(max_length=15)
active = models.BooleanField(default=True)
receive_newsletter = models.BooleanField(default=False, blank=True)
以及我将它们全部导入的文件：
kofiapi/api/models.py：
from kofiapi.api.users.models import User, UserProfile
from kofiapi.api.products.models import Product
这是我的项目结构：

我已经尝试过：
- 在运行命令之前删除 db.sqlite3
__pycache__从项目中删除所有文件夹- 运行
python3.6 manage.py migrate --fake（运行不返回错误）
与在我的笔记本电脑上正常运行的原始项目相比，没有任何变化。
谢谢
解决方案
