我是 Django 新手，我已經實現了一個有效的表單，現在我想在 URL 上設置權限。提交表單后，它會將我重定向到此 URLhttp://127.0.0.1:8000/success/無需提交表單，我可以手動輸入 URL 名稱http://127.0.0.1:8000/success/，它會將我帶到同一頁面。如何設置“成功”網址的權限，以便用戶無法手動查看頁面，除非表單有效并提交？我需要一個裝飾器嗎？模型：class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,blank=True,null=True) profile_pic = models.ImageField(upload_to='ProfilePicture/', default="ProfilePicture/avatar.png", blank=True) phone = models.IntegerField(default='0', blank=True) email = models.EmailField(blank=True) date_of_birth = models.CharField(max_length=50, blank=True) address = models.TextField(blank=True) date = models.DateTimeField(auto_now_add=True) class Meta: verbose_name = 'Profile' verbose_name_plural = 'Profiles' ordering = ['-date'] '''Method to filter database results''' def __str__(self): return self.user.usernameclass CotCode(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) cot_code = models.IntegerField(default='0', blank=True) date = models.DateTimeField(auto_now_add=True) class Meta: verbose_name = 'CotCode' verbose_name_plural = 'CotCode' ordering = ['-date'] def __str__(self): return self.user.username網址：path('cot/', TransferCOTView, name='transfer_cot'),path('success/', SuccessfulView, name='successful_trans'),瀏覽次數：@login_requireddef TransferCOTView(request): form = CotCodeForm(request.POST) if request.method == "POST": if form.is_valid(): cot_code = form.cleaned_data.get('cot_code') try: match = CotCode.objects.get(cot_code=cot_code) return redirect('site:successful_trans') except CotCode.DoesNotExist: messages.info(request, "Wrong code")

一個簡單的選項是設置一個會話變量，通知表單已發布且有效，并在顯示成功頁面之前檢查它。請參閱此處的會話示例https://docs.djangoproject.com/en/3.1/topics/http/sessions/#examples
例如
def formview(request):
# process form
request.session["form_filled"] = True
# redirect to success
def success(request):
if not request.session.get("form-filled"):
raise Http404("Form not filled")
del request.session["form_filled"] # success view visible once after form is filled
# return view template
您還可以檢查用戶是否在成功視圖中填寫了 COT 代碼。
def SuccessfulView(request):
cot_code_exists = CotCode.objects.filter(user=request.user).count()
if not cot_code_exists:
raise Http404("Cot code does not exist for user")
return render(request, 'successful_transfer.html')
