Django - 在模板呈现具有动态字段的脆皮表单时出错：'int'对象没有属性'get'

Question

我一直在尝试用给定数量的字段实现动态表单，并用清晰的表单呈现这些表单。但是，在呈现页面时会出现以下错误：

Template error:
In template C:UsersUSER14Documentstestpreplibsite-packagescrispy_formstemplatesbootstrap4errors.html, error at line 1
'int' object has no attribute 'get'
1 :  {% if form.non_field_errors %} 
2 :     <div class="alert alert-block alert-danger">
3 :         {% if form_error_title %}<h4 class="alert-heading">{{ form_error_title }}</h4>{% endif %}
4 :         <ul class="m-0">
5 :             {{ form.non_field_errors|unordered_list }}
6 :         </ul>
7 :     </div>
8 : {% endif %}
9 : 
Traceback (most recent call last):

File "C:UsersUSER14Documentstestpreplibsite-packagesdjangoformsforms.py", line 304, in non_field_errors
return self.errors.get(NON_FIELD_ERRORS, self.error_class(error_class='nonfield'))

getter = data.get
Exception Type: AttributeError at /upload/1/SingleCorrect/10/
Exception Value: 'int' object has no attribute 'get'

究竟是什么导致了这个错误？

以下是我正在使用的代码片段。

views.py:

def uploadQP(request,qp,typeofq,numberOfquestion):
if request.method == 'POST':
form=UploadQuestions(repetitions=numberOfquestion,data=request.POST,files=request.FILES)
if form.is_valid():
if typeofq=='SingleCorrect':
for i in range(numberOfquestion):
files=SingleIntegerType()
files.QuestionPaper=get_object_or_404(QuestionPaper,pk=qp)
files.question=request.FILES['question_%d' % i]
files.correct_answer=request.POST['correct_answer_%d' % i]
files.QuestionNumber=request.POST['question_number_%d' % i]
files.save()
return redirect('create_q')
elif request.method=='GET':
form=UploadQuestions(numberOfquestion)
return render(request, 'upload_q.html',{'form':form})

forms.py

class UploadQuestions(forms.Form):
def __init__(self, repetitions, *args, **kwargs):
super(UploadQuestions, self).__init__(*args, **kwargs)
for i in xrange(repetitions):
self.fields['question_number_%d' % i]=forms.IntegerField(label="Enter question number ",widget=forms.NumberInput(attrs={'class': 'form-control', 'placeholder': '1'}))
self.fields['question_%d' % i] = forms.ImageField(label="Select the Image")
self.fields['correct_answer_%d' % i] = forms.ChoiceField(label="Select the correct Option",initial=('A','A'),choices=SINGLE_CORRECT_OPTIONS, widget=forms.Select(attrs={'class': 'custom-select category', 'required': 'true'}))

型号.py

class SingleIntegerType(models.Model):
question=models.ImageField(upload_to=create_path)
correct_answer=models.CharField(max_length=10, choices=SINGLE_CORRECT_OPTIONS)
QuestionNumber = models.IntegerField(null=True)
QuestionPaper=models.ForeignKey(QuestionPaper, on_delete=models.DO_NOTHING)
def __str__(self):
return str(self.correct_answer)

编辑：在注释中的建议的帮助下，代码已被更正。

views.py中的代码片段已在注释的帮助下得到更正。当前的代码段提供了一种变通方法，除了使用表单集之外，还可以使用动态数量的表单字段。
