如何在django 1.9中扩展用户模型？

Question

我一直在寻找解决这个问题,我想在我的Profile模型中添加简单的东西,如头像,联系信息等.但是,当我在网上找到如何做到这一点的教程时,我只遇到了错误.

这就是我的模型(track/models.py):

from django.db import models
from django.core.exceptions import ValidationError
from django.core.files.images import get_image_dimensions
from django.contrib.auth.models import User

...

class Profile(models.Model):

    def generate_user_folder_avatar(instance, filename):
        return "uploads/users/%s/%s.png" % (instance.user, 'avatar')

    user = models.OneToOneField(User)

    avatar = models.ImageField(upload_to=generate_user_folder_avatar,validators=[is_square_png])

    def create_user_profile(sender, instance, created, **kwargs):
        if created:
            Profile.objects.create(user=instance)

    post_save.connect(create_user_profile, sender=User)

我已经设置了AUTH_PROFILE_MODULE = 'tracks.Profile'settings.py,但是当我运行我的服务器时,我收到此错误:

NameError: name 'post_save' is not defined

知道我在这里做错了什么吗？我正在使用Django 1.9和Python 3

Answer 1

NameError: name 'post_save' is not defined

你应该做导入:

from django.db.models.signals import post_save

注意#1:您可能对Django提供更加明确和清晰的扩展用户模型的方式感兴趣:https: //docs.djangoproject.com/en/1.9/topics/auth/customizing/#extending-django-s -default用户

注意#2:您可能想要连接不在模型中某处的信号,但是这样:https://stackoverflow.com/a/21612050/699864
