获取“光标” _django_curs_140244427998976_3“不存在”错误

Question

我正在创建模型形式。我已经设法从表中提取我要使用的字段（使用postgresql）：

表格：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul class="render-menu">
  <li class="font-size">list 1</li>
  <li class="font-size">list 2</li>
  <li class="font-size">list 3</li>
  <li class="font-size">list 4</li>
</ul>

表格：

class Response(models.Model):
    Question = models.ForeignKey(Question, on_delete=models.CASCADE)
    Topic = models.ForeignKey(Topic, on_delete=models.CASCADE)
    Response = models.TextField()
    Client = models.ForeignKey(ClientDetail, on_delete=models.CASCADE)
    Planit_location = models.ForeignKey(Planit_location, on_delete=models.CASCADE)

    def __str__(self):
        return self.Response

我现在想在Planit_locaiton字段中添加，但是当我这样做时，出现标题中所述的光标错误。不知道为什么。这是位置表：

class ResponseForm(forms.ModelForm):
    class Meta:
        model = Response
        fields = ('Response', 'Topic', 'Client')
        widgets = {
           'Response': Textarea(attrs={'rows':3, 'cols':200}),
        }

HTML：

class Planit_location(models.Model):
    Planit_location = models.CharField(max_length=255)

    def __str__(self):
        return self.Planit_location

views.py：

 <form method="post" name="uploadform" style="margin-left: 16px">
    {% csrf_token %}
    <h4>Add Data</h4>
    <table>
            {{ qform.as_table }}
            {{ rform.as_table }}
    </table>
    <button type="submit" class="btn btn-default">Submit</button>
</form>

编辑

跟踪：

def adddata(request):
if request.user.is_authenticated:
    username = request.user.username

if request.method == 'POST':
    qform = QuestionForm(request.POST)
    rform = ResponseForm(request.POST)
    if qform.is_valid() and rform.is_valid():
        qf = qform.save()
        rf = rform.save(commit=False)
        rf.Question = qf
        rf.save()
        return render(request, 'app/adddatatest.html', {
           "qform": QuestionForm(),
           "rform": ResponseForm(),
           "username": username,
        })
else:
    qform = QuestionForm()
    rform = ResponseForm()
return render(request, 'app/adddatatest.html', {
    "qform": QuestionForm(),
    "rform": ResponseForm(),
    "username": username,
})
