Python 错误非空约束失败：使用3个模型自定义表单django all auth（外键）

我正在学习django，在我的一个挑战中，我想在注册表单django all auth中添加3个外键，但我有一个错误：NOT NULL约束失败：advertising_profile.user_id 请你帮我解释一下我失败了什么

我正试图将此信息保存到注册表中

    ==========views.py==================
def register(request):
    form = CustomSignUpProfileModelForm()
    if request.method == "POST":
        form = CustomSignUpProfileModelForm(data=request.POST)
        if form.is_valid():
            #user = form['customSignUp'].save(commit=False)
            profile = form.save(commit=False)
            profile.user = request.user
            profile.save()

            #user = form.save()
            if profile is not None:
                do_login(request, user)
                return redirect('welcome')

    #form.fields['username'].help_text = None
    #form.fields['password1'].help_text = None
    #form.fields['password2'].help_text = None

    return render(request,"account/signup.html",{'form':form})

在此行配置文件中。user=request.user但您应该确认您的模型在此行配置文件中应该有user

。user=request.user但您应该确认您的模型应该有user
