NOT NULL约束失败：用户_profile.user_id文件

Question

我正在使用django allauth进行用户注册和登录，但我只有一个称为“单击完成”的步骤，这应该是完成他们的配置文件时，用户注册。但我有以下错误。 首先，我已经试过了

模型.py

class CustomUser(AbstractUser):

def __str__(self):
    return self.email


class Profile(models.Model):
    user = models.OneToOneField('users.CustomUser', on_delete=models.CASCADE)

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

表单.py

^{pr2}$

视图.py

def profile(request):

if request.method == 'POST':
    form = ProfileForm(request.POST)

    if form.is_valid():
        form.save()
        redirect('dashboard')
else:
    form = ProfileForm()
return render(request, 'users/profile.html', {'form':form})

我得到了这个错误

Traceback (most recent call last):

我已经找到了一些答案，但没有一个对我的案子有效。 任何帮助都将不胜感激！在

Answer 1

您需要在Profile对象中添加user字段的值。在

为此，在保存配置文件之前，可以从request.user附加用户。使用form.save(commit=False)将返回尚未保存在数据库中的概要文件实例，然后将用户添加到该概要文件实例中。在

例如：

from django.contrib.auth.decorators import login_required

@login_required
def profile(request):

    if request.method == 'POST':
        form = ProfileForm(request.POST)
        if form.is_valid():
            profile = form.save(commit=False)
            profile.user = request.user
            profile.save()
            return redirect('dashboard')
     else:
        form = ProfileForm()
     return render(request, 'users/profile.html', {'form':form})
