Question

我正在使用django-allauth进行用户注册和登录，但是我只有一个名为“单击完成”的步骤，当用户注册时，这似乎应该完成他们的个人资料。但是我得到以下错误。首先，到目前为止，我在这里已经尝试过

model.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

forms.py

 class CustomUserCreationForm(UserCreationForm):

    class Meta(UserCreationForm):
        model = CustomUser
        fields = ('username', 'email')

  class CustomUserChangeForm(UserChangeForm):

    class Meta:
        model = CustomUser
        fields = ('username', 'email')



  class ProfileForm(forms.ModelForm):
     company_name = forms.CharField(max_length=100)
     phone_number = forms.CharField(max_length=20)
     city = forms.CharField(max_length=15)
     address = forms.CharField(max_length=255)

    class Meta:
        model = Profile
        fields = ['company_name', 'phone_number', 'city', 'address']

views.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})

我收到此错误

我已经搜索了一些答案，但是在我的情况下，没有一个有效。任何帮助将不胜感激！

您需要在Profile对象中添加user字段的值。

为此，您可以在保存配置文件之前从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Profile实例，然后将用户添加到该Profile实例。

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})

NOT NULL约束失败：users_profile.user_id
