错误： 1）user.Login.password：（fields.E304）“Login.password”的反向访问者与“Login.username”的反向访问者冲突。 2）user.Login.username :( fields.E304）“Login.username”的反向访问者与“Login.password”的反向访问者冲突。

models.py

from django.db import models
from django.core.urlresolvers import reverse

class User(models.Model):
     first_name = models.CharField(max_length=50)
     last_name = models.CharField(max_length=50)
     username = models.CharField(max_length=100)
     password = models.CharField(max_length=50)
     confirm_password = models.CharField(max_length=50)
     email = models.EmailField(max_length=100)
     position = models.CharField(max_length=50)

     def get_absolute_url(self):
           return reverse('user:register', kwargs={'pk': self.pk})

class Login(models.Model):
     username = models.ForeignKey(User, on_delete=models.CASCADE)
     password = models.ForeignKey(User, on_delete=models.CASCADE)

     def __str__(self):
          login = {'username': self.username, 'password': self.password}
          return login

Answer 1

您可以使用related_name属性

来解决问题

class Login(models.Model):
     username = models.ForeignKey(User, on_delete=models.CASCADE, related_name="username_users")
     password = models.ForeignKey(User, on_delete=models.CASCADE, related_name="password_users")

但是我没有理由让你的密码和用户名都与用户有fk关系!!!
