查看投诉页面上的投诉未显示

Question

我正在创建一个投诉管理系统，用户可以输入他们的投诉，以及查看和编辑他们，也可以查看其他用户的投诉。在用户可以查看其他投诉的页面上，没有显示任何投诉或数据。我做什么好？

这应该会显示出来：

​

但这就是我们所看到的：

我的models.py：

class Profile(models.Model):
   user = models.OneToOneField(User,null= True , blank = True, on_delete= models.CASCADE)
   profile_pic = models.ImageField(default = "msi.jpg", null = True, blank= True, upload_to= 
  'static/profileimages')
  first = models.CharField(max_length=500, null=True)
   last = models.CharField(max_length=500, null=True)
   email = models.CharField(max_length=500, null=True)
   mobile_number = models.IntegerField(null=True)
   location = models.CharField(max_length= 500, null= True)
   postal = models.IntegerField(null=True)

   def __str__(self):
       return self.first

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

views.py：

       reportnumber = cleaned_data.get('reportnumber')
       event_text = cleaned_data.get('event_text')
       if not reportnumber and not event_text:
           raise forms.ValidationError('You have to write something!')
       return cleaned_data

在获取上下文数据方法的views.py中...它实际上没有返回上下文。例如，您拥有：

def get_context_data(self, *args, **kwargs):
   context = super().get_context_data(*args, **kwargs)
   context["complaints"] = self.model.objects.exclude(user = self.request.user)

您应该在此处添加一个return语句，以返回您已更新的上下文。

def get_context_data(self, *args, **kwargs):
   context = super().get_context_data(*args, **kwargs)
   context["complaints"] = self.model.objects.exclude(user = self.request.user)
   return context
