Django 模型表单实例未通过

我将模型的一个实例传递到modelForm中，但是在视图中，当我打印表单时，模型中的值不会显示。另外，在我的模板上呈现表单时，实例中的值不会显示

视图.py

def support_ticket_view(request, id=None): 

    id = int(id)
    instance = SupportTicket.objects.get(id=id, user=user)

    form = SupportTicketEditForm(request.POST or None, request.FILES or None, instance=instance)

    context = { 
    'form': form,      
    }

    return render(request, 'accounts/support_ticket_view.html', context)

class SupportTicketEditForm (forms.ModelForm):    

    def __init__(self, *args, **kwargs):
        self.instance = kwargs.pop('instance',None) 
        super(SupportTicketEditForm, self).__init__(*args, **kwargs) 


    class Meta:
        model = SupportTicket
        fields = (      
            'image',
            'body_question',            
            'urgency',
            'question_type',                      
            'status',
        )    

        widgets = {
            'image': ImageThumbnailFileInput
        }

class SupportTicket(models.Model):
   user = models.ForeignKey(User, on_delete=models.CASCADE)    
   question = models.TextField(max_length=10000, null=True, blank=False)

    def __str__(self):
       return self.user.username 

forms.py

def support_ticket_view(request, id=None): 

    id = int(id)
    instance = SupportTicket.objects.get(id=id, user=user)

    form = SupportTicketEditForm(request.POST or None, request.FILES or None, instance=instance)

    context = { 
    'form': form,      
    }

    return render(request, 'accounts/support_ticket_view.html', context)

class SupportTicketEditForm (forms.ModelForm):    

    def __init__(self, *args, **kwargs):
        self.instance = kwargs.pop('instance',None) 
        super(SupportTicketEditForm, self).__init__(*args, **kwargs) 


    class Meta:
        model = SupportTicket
        fields = (      
            'image',
            'body_question',            
            'urgency',
            'question_type',                      
            'status',
        )    

        widgets = {
            'image': ImageThumbnailFileInput
        }

class SupportTicket(models.Model):
   user = models.ForeignKey(User, on_delete=models.CASCADE)    
   question = models.TextField(max_length=10000, null=True, blank=False)

    def __str__(self):
       return self.user.username 

型号.py

def support_ticket_view(request, id=None): 

    id = int(id)
    instance = SupportTicket.objects.get(id=id, user=user)

    form = SupportTicketEditForm(request.POST or None, request.FILES or None, instance=instance)

    context = { 
    'form': form,      
    }

    return render(request, 'accounts/support_ticket_view.html', context)

class SupportTicketEditForm (forms.ModelForm):    

    def __init__(self, *args, **kwargs):
        self.instance = kwargs.pop('instance',None) 
        super(SupportTicketEditForm, self).__init__(*args, **kwargs) 


    class Meta:
        model = SupportTicket
        fields = (      
            'image',
            'body_question',            
            'urgency',
            'question_type',                      
            'status',
        )    

        widgets = {
            'image': ImageThumbnailFileInput
        }

class SupportTicket(models.Model):
   user = models.ForeignKey(User, on_delete=models.CASCADE)    
   question = models.TextField(max_length=10000, null=True, blank=False)

    def __str__(self):
       return self.user.username 

删除以下内容：

   def __init__(self, *args, **kwargs):
        self.instance = kwargs.pop('instance',None) 
        super(SupportTicketEditForm, self).__init__(*args, **kwargs) 

谢谢丹尼尔·罗斯曼

删除了以下内容：

   def __init__(self, *args, **kwargs):
        self.instance = kwargs.pop('instance',None) 
        super(SupportTicketEditForm, self).__init__(*args, **kwargs)

谢谢丹尼尔·罗斯曼

但是您的实例只包含

'user'

和

'question'

，而您的表单似乎包含

'image'

，

'body\u question'

，

'emergency'

等。您为什么要在

\uu init\uuuu>中从kwargs弹出实例？事实上，你为什么要定义
\uuuu init\uuu
？嗨，丹尼尔，你说得对。我已经删除了definit，现在它可以工作了：）再次感谢。永远感谢你的帮助！但是您的实例只包含
