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，用户可以在其中输入他们的投诉以及查看和编辑它们，还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。我该怎么办？

这应该会出现：

但这就是显示的内容：

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：

class OtherPeoplesComplaints(TemplateView):
   model = Complaint
   form_class = ComplaintForm
   template_name = 'userComplaints.html'
   def get_context_data(self, *args, **kwargs):
       context = super().get_context_data(*args, **kwargs)
       context["complaints"] = self.model.objects.exclude(user = self.request.user)

forms.py：

class CreateUserForm(UserCreationForm):
   email = forms.EmailField()
   password2 = None
   class Meta:
       model = User
       fields = ['username','first_name', 'last_name','email', 'password1']

class ProfileForm(ModelForm):
   class Meta:
       model = Profile
       fields = '__all__'
       exclude = ['user']
       widgets = {
           'profile_pic': forms.FileInput()
       }

class DateInput(forms.DateInput):
   input_type = 'date'

class ComplaintForm(ModelForm):
   class Meta:
       model = Complaint
       fields = '__all__'
       widgets = {
           'reportnumber': forms.TextInput(attrs={'placeholder': 'Report number'}),
           'event_type': forms.TextInput(attrs={'placeholder': 'Event type'}),
           'eventdate': DateInput(),

           'product_code': forms.TextInput(attrs={'placeholder': 'Enter Product Code'}),
           'brand_name': forms.TextInput(attrs={'placeholder': 'Enter Brand Name'}),
           'exemption': forms.TextInput(attrs={'placeholder': 'Enter Exemption'}),
           'patient_problem': forms.TextInput(attrs={'placeholder': 'Enter Patient Problem'}),
       }
    
   def clean(self):
       cleaned_data = super(ComplaintForm, self).clean()
       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

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">All Complaints</h1>

    </div>

Answer 1

在您的views.py 中获取上下文数据方法...它实际上并没有返回上下文。例如，您有：

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
