我在 Django 中的代码似乎有什么问题？

Question

urls.py:

urlpatterns = [
....
path('My-History/', accounts.views.History, name='MyHistory'),
path('Complaint/<int:id>/edit', accounts.views.EditComplaint.as_view(), name='Complaint')
]

views.py:

def History(request):
  complaint_data = Complaint.objects.filter(user=request.user) 
  context = { 'complaint':complaint_data }
  return render(request, 'myHistory.html', context)

class EditComplaint(UserPassesTestMixin, UpdateView):
   model = Complaint
   fields = ('info', 'reportnumber', 'eventdate', 'event_type', 'device_problem', 
  'manufacturer', 'product_code', 'brand_name', 'exemption', 'patient_problem', 'event_text', 
  'document') 

   def form_valid(self, request):
       complaint = request.user.complaint
       form = ComplaintForm(instance=complaint)
       if request.method == 'POST':
          form = ComplaintForm(request.POST, request.FILES, instance=complaint)
          if form.is_valid():
             form.save()
       context = {'form': form}
       return render(request, 'newcomplaint.html', context)

   def test_func(self):
       complain = self.get_object()

       if self.request.user == complain.user:
           return True
       raise Http404(_('This complain does not exist'))

models.py:

class Complaint(models.Model):
   user = models.ForeignKey(User, on_delete= models.CASCADE, null = True, blank=True)
   id = models.AutoField(blank=False, primary_key=True)
   reportnumber = models.CharField(max_length=500 ,null = True, blank= False)
   eventdate = models.DateField(null=True, blank=False)
   event_type = models.CharField(max_length=300, null=True, blank=True)
   device_problem = models.CharField(max_length=300, null=True, blank=True)
   manufacturer = models.CharField(max_length=300, null=True, blank=True)
   product_code = models.CharField(max_length=300, null=True, blank=True)
   brand_name = models.CharField(max_length = 300, null=True, blank=True)
   exemption = models.CharField(max_length=300, null=True, blank=True)
   patient_problem = models.CharField(max_length=500, null=True, blank=True)
   event_text = models.TextField(null=True, blank= True)
   document = models.FileField(upload_to='static/documents', blank=True, null=True)

   def __str__(self):
       return self.reportnumber

我的历史模板：

<div class="col-lg middle middle-complaint-con">
        <i class="fas fa-folder-open fa-4x comp-folder-icon"></i>
        <h1 class="all-comp">My Complaints</h1>
        <p class="all-comp-txt">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>

        {%for c in complaint %}
        <a href="{% url 'Complaint' complaint.id %}" style="color:black;">
            <div class="container comp-con-{{forloop.counter0}}">
                <p style="color: #D37A19; margin-left: -130px; margin-top: -5px;">Report number:</p>
                <p class="history-level-1">{{c.reportnumber}}</p>
                <p class="comp-title-1">{{c.event_type}}</p>
                <p class="comp-sub-1">{{c.event_text}}</p>
            </div>
        </a> {%endfor%}
    </div>

注意：当我删除“{% url 'Complaint' complaint.id %}”时，我的历史页面出现了，但我无法进入详细信息页面个人投诉。如果我将此 url 保留在其中，则会显示此页面：

我做错了什么？？

Answer 1

你的url“投诉”被设置为接收一个参数......但是正如错误回溯所说，没有任何参数被传递到投诉url......

改变这个并尝试，

这个

{%for c in complaint %}
        <a href="{% url 'Complaint' complaint.id %}" style="color:black;">

进入

{%for c in complaint %}
        <a href="{% url 'Complaint' c.id %}" style="color:black;">

由于您正在使用 'c' 遍历投诉查询对象，因此您必须通过 c.id

访问每个 ID
