我正在嘗試為請求忘記密碼的用戶生成令牌。我有一個模型來處理和存盤這個。
模型.py
class ForgetPassword(models.Model):
user = models.ForeignKey(CustomUser, on_delete= models.CASCADE)
forget_password_token = models.CharField(max_length=100)
created_at = models.DateTimeField(auto_now_add= True)
def __str__(self):
return self.user.email
處理請求的視圖函式如下
視圖.py
def forget_password(request):
try:
if request.method == 'POST':
user_email = request.POST.get('email')
if CustomUser.objects.filter(email = user_email).exists():
user_obj = CustomUser.objects.get(email = user_email)
name = user_obj.full_name
plan = user_obj.plan
print("\n this is the user : ", user_obj, " this is its name : ", name,"\n")
token = str(uuid.uuid4())
fp = ForgetPassword.objects.get(user = user_obj)
fp.forget_password_token = token
fp.save()
forget_password_mail.delay(user_email, name, token)
messages.info(request, 'An email has been sent to your registered email.')
return redirect('forget-password')
else:
messages.info(request, 'User does not exist')
return redirect('forget-password')
except Exception as e:
print("\nthe exception is comming from forget_password : ", e, "\n")
return render(request, 'fp_email_form.html')
因此，在這里我嘗試首先從我的 CustomUser 模型中獲取 user_obj 中的用戶，然后嘗試在 ForgetPassword 模型中獲取相同的用戶并針對該用戶存盤令牌。但我收到以下例外
ForgetPassword matching query does not exist.
請建議或糾正我的錯誤。
uj5u.com熱心網友回復：
您沒有與您嘗試獲取的用戶物件關聯的 ForgetPassword 物件，
fp = ForgetPassword.objects.get(user = user_obj)
相反，您應該使用get_or_create.
