Question

我不明白我做错了什么。我正在尝试通过表单更新模型，我一直在线学习他们都指向获得“id”的方向。我已经做到了，但我一直收到这个错误：

无法解析关键字＆＃39; i＆＃39;进入田野。选项包括：id，joined_on，user，user_id

id密钥在那里，但他认为是一个＆＃39; i＆＃39;我正在寻找什么。

任何想法？

view.py

fillInDefaults :: Alternative f => Foo f -> f TotalFoo
fillInDefaults = hsequence . (<> defaultFoo)

-- fromJust (unsafely) asserts that there aren't
-- any `Nothing`s in the output of `fillInDefaults`
fillInDefaults' :: PartialFoo -> TotalFoo
fillInDefaults' = fromJust . fillInDefaults

model.py

def testRegistration(request):
                    id = UserProfileModel.objects.get('id')
                    user_status_form = UserDetailsForm(request.POST or None, instance=id)
                    if request.method == 'POST':
                            if user_status_form.is_valid():
                                    user_status = user_status_form.save(commit=False)
                                    user_status.user = get_user(request)
                                    user_status.save()
                                    user_status_form = UserDetailsForm()
                            else:
                                    user_status_form = UserDetailsForm()

                            return HttpResponseRedirect('testRegistration')

                    return render(
                            request, 'registrationTest.html',
                            {'user_status_form' : user_status_form,
                             }
                    )

回溯环境：

class UserProfileModel(models.Model):
            user = models.OneToOneField(User, unique=True)
            joined_on = models.DateTimeField(auto_now=True, null=True)

错误在此行的视图中，

id = UserProfileModel.objects.get('id')

用类似的东西替换它，

id = UserProfileModel.objects.get(user__username=request.user.username)

objects.get方法将field_names和values作为关键字参数，并返回具有匹配条件的对象。从您的角度来看，我想您想获取当前登录用户的UserProfile的ID。为此，您需要访问用户字段的ID（ForeignKey to User）并将其与当前用户（request.user）匹配。
