Question

所以我正在使用内置的Django登录表单，我希望我的博客模型继承使用表单创建的所有用户，但它没有显示在博客模型中。

模型

class Blogger(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE,null=True)
    follows = models.ManyToManyField('self', related_name='following', symmetrical=False)

    def __str__(self):
        return self.user.username

查看注册

def signup(request):
    if request.method == 'POST':
        form = SignUpForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            login(request, user)
            return redirect('/blog')
    else:
        form = SignUpForm()
    return render(request, 'winterblog/signup.html', {'form': form})

使用Django表格

def signup(request):
    if request.method == 'POST':
        form = SignUpForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            raw_password = form.cleaned_data.get('password1')
            user = authenticate(username=username, password=raw_password)
            login(request, user)
            return redirect('/blog')
    else:
        form = SignUpForm()
    return render(request, 'winterblog/signup.html', {'form': form})

非常感谢！

您的注册视图不会创建Blogger实例。您可以在视图中为新用户创建博客记录：

def signup(request):
if request.method == 'POST':
    form = SignUpForm(request.POST)
    if form.is_valid():
        form.save()
        username = form.cleaned_data.get('username')
        raw_password = form.cleaned_data.get('password1')
        user = authenticate(username=username, password=raw_password)
        Blogger.objects.create(user=user)
        login(request, user)
        return redirect('/blog')
    else:
        form = SignUpForm()
    return render(request, 'winterblog/signup.html', {'form': form})

另一个选项是添加signal，以便在创建新用户后自动创建新博客：

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

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

模型不继承用户数据
