提交后 Django 模式关闭

Question

我开发了一个简单的表单加载到 bootstrap 模态中，表单得到渲染，一切正常。然而，当我提交表单时，模态不提交并关闭，因为我得到重定向错误不正确。我使用的是 Bootstrap Modal 没有 Jquery 以便于实施，表单是通过详细视图函数加载的，提交是通过另一个视图函数 'test1'.

我收到以下错误：

NoReverseMatch 在 /split/3 反向 'applicationdetail' 没有找不到参数。尝试了 1 种模式：['applicationdetail/(?P[0-9]+)$']

下面是我的概念代码：

models.py:

class Startup ( models.Model ) :
    author = models.OneToOneField ( User , on_delete = models.CASCADE )
    startup_name = models.CharField ( max_length = 32 , null = False , blank = False )

class Score_Appeal(models.Model):
    appeal_score = models.ForeignKey(Startup, on_delete = models.CASCADE)
    appeal_evaluator = models.ForeignKey(User, on_delete = models.CASCADE)
    appeal = models.CharField ('Appeal', max_length = 100 , null = False , blank = False , choices = Choice.EVALUATION , default = '' )
    appeal_comment = models.TextField(max_length = 100, blank = True)

views.py:

@login_required
@inv_required
def global_list(request):
    startup = Startup.objects.all()
    return render(request, 'inv_template/global_list.html', {'startup': startup})

@login_required
@inv_required
def applicationdetail(request, pk):
    obj = Startup.objects.filter(pk = pk)
    form = SplitForm1
    return render(request, 'inv_template/application_detail.html', {'data': obj, 'form':form})

@login_required
@inv_required
def test1 (request, id):
    obj = Startup.objects.filter (id=id)[0]
    R = get_object_or_404 ( Startup , startup_name = obj )

    if request.method == 'POST' :
        form = SplitForm1 (request.POST)
        instance = form.save ( commit = False )
        instance.appeal_score = R
        instance.appeal_evaluator = request.user
        instance.save ( )
        return redirect ( 'applicationdetail' )
```````````````

**urls.py:**

````````````
    path ( 'globallist/' , views.global_list , name = 'globallist' ) ,
    path ( 'applicationdetail/<int:pk>' , views.applicationdetail , name = 'applicationdetail' ) ,
    path ( 'split/<int:id>' , views.test1 , name = 'split' ) ,
```````````
**Templates (the detail view with the modal in it):**

``````````````

您忘记在 redirect 方法中指定 pk 参数：


def test1 (request, id):
    obj = Startup.objects.filter (id=id)[0]
    R = get_object_or_404 ( Startup , startup_name = obj )

    if request.method == 'POST' :
        form = SplitForm1 (request.POST)
        instance = form.save ( commit = False )
        instance.appeal_score = R
        instance.appeal_evaluator = request.user
        instance.save ( )
        <b>return redirect('applicationdetail', pk=id)</b>
