如何从Django中的数据库中检索与外键关联到User模型中的用户的对象

Question

我试图从用户模型中捕获用户，然后将该信息用作外键以将数据保存到另一个模型。注册表单会将用户信息保存到用户模型和其他UserProfile模型中。然后，该数据用于查询返回帐户ID号的API。然后，该ID号将存储在另一个通过外键链接到User模型的数据库中。

我尝试了很多可能性，但是没有用。

class registeraccount(TemplateView):

    def get(self, request):     
        form = ExtendedUserCreationForm()
        profile_form = UserProfileForm()

        post1 = User.objects.all()
        post2 = UserProfile.objects.all()



        return render(request, 'main/register.html', context={'form': form, 'profile_form': profile_form})

    def post(self, request):
        if request.method == "POST":
            form = ExtendedUserCreationForm(request.POST)
            profile_form = UserProfileForm(request.POST)

            if form.is_valid() and profile_form.is_valid():
                user = form.save()
                user.save() 

                profile = profile_form.save(commit=False)
                profile.user = user
                profile.save()

                username = form.cleaned_data.get('username')
                password = form.cleaned_data.get('password1')
                user = authenticate(username=username, password=password)
                login(request, user)

            obj = User.objects.order_by("-id")[0]

            a = obj

            print(a.username)

            obj2 = UserProfile.objects.order_by("-id")[0]

            b = obj2

            print(b.street)

            try:
                login_id = 'ap133875@gmail.com'
                api_key = '##############################'
                environment = currencycloud.Config.ENV_DEMO
                client = currencycloud.Client(login_id, api_key, environment)

                account = client.accounts.create(account_name=(a.username), legal_entity_type=(b.legal_entity_type), street=(b.street), city=(b.city), postal_code=(b.postal_code), country=(b.country))

                print("Your account has been created")

                account = client.accounts.find()

                c = account
                d = (c[-1].id)

                print(d)


                my_p =  User.objects.get(request.user)


                post = Currencyclouds(CC_account_id=d, user=my_user)

                post.save()



                return render(request, 'main/account_created.html', {'content': ['Your account is created']}) 




            except ApiError as e:
                print("Conversion encountered an error: {0} (HTTP code {1})".format(e.code, e.status_code))



            print(p)



        else:
            form = ExtendedUserCreationForm()
            profile_form = UserProfileForm()

        return render(request, 'main/account_created.html', {'content': "Your account is created"})
