使用signals.py创建用户时自动创建Django Profile

Question

我在signals.py 中有一个问题。 Parameter 'sender' value is not used. 并且Parameter 'kwargs' value is not used. . 在我之前的项目中，这工作正常，但是在这个项目中User(AbstractUser) model 是在 models.py 中引入的，然后这个问题就开始了。

SIGNALS.PY

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver
from .models import Profile, MedicalInfo


@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)


@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()

Models.py

class User(AbstractUser):
    is_doctor = models.BooleanField(default=False)
    is_public = models.BooleanField(default=False)

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

    def __str__(self):
        return f'{self.user.username} Profile'

    def save(self, *args, **kwargs):
        super(Profile, self).save(*args, **kwargs)

        img = Image.open(self.image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.image.path)

VIEWS.PY

@login_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)

        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f'Your account has been updated!')
            return redirect('public:profile')

    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
        'u_form': u_form,
        'p_form': p_form,
    }
    return render(request, 'all_users/public/profile.html', context)

由于您自定义了用户，因此必须将from django.contrib.auth import get_user_model也您需要将自定义 model 添加到设置

AUTH_USER_MODEL = 'myapp.MyUser'
