Having a ModuleNotFoundError! in Django

Question

我有一个项目，其中有一个登录应用程序和一个主页应用程序。项目文件看起来像这个

• 登录

  • 主页

    • 模型.py

  • 登录

    • 设置.py
    • urls.py

  • 用户注册

    • 模型.py

  • 管理员.py

这是usersignup/models.py"从django.db导入型号

class UserDetail(models.Model):
first_name = models.CharField(max_length=225)
middle_name = models.CharField(max_length=255, blank=True, null=True)
last_name = models.CharField(max_length=255)
email = models.EmailField()
def __str__(self):
return self.first_name
class WebDetail(UserDetail):
# user = models.OneToOneField(UserDetail, on_delete=models.CASCADE, primary_key=True,)
username = models.CharField(max_length=255)
password = models.CharField(max_length=255)

''

这里是主页/型号.py

''

from django.db import models
from login.usersignup.models import UserDetail

class UploadProfilePicture(models.Model):
caption = models.CharField(max_length=2000)
image = models.ImageField(upload_to='images/')

class Profile(models.Model):
user = models.ForeignKey(UserDetail, on_delete=models.CASCADE)

''

当我跑步的时候''

python manage.py check

from login.usersignup.models import UserDetail
ModuleNotFoundError: No module named 'login.usersignup'

那么，有什么方法可以将usersignup/models中的UserDetail类导入主页/models吗？

感谢您的贡献

Answer 1

而不是使用：

from login.usersignup.models import UserDetail

尝试使用这个：

from usersignup.models import UserDetail
