'TypeError' 对象没有属性 ''

如何解决'TypeError' 对象没有属性 ''

我在 Django 中使用 SendGrid，我有两个独立的功能。一个使用 SendGrid 代码（见下文 - 工作代码）工作，然后另一个不断收到错误 - 'TypeError' 对象没有属性 'booking_message'。

我认为这个问题很小，但我一直想念它。

感谢我能得到的任何帮助。

（注意 - 我已经取出了模板 ID、发件人和收件人电子邮件地址以及 SendGrid API 应用程序 ID，只是让 ''）我没有时间在发布之前使用环境变量来隐藏密钥。

工作代码

class ASPBookingsCreateView(CreateView):
    form_class = ASPBookingsForm
    model = ASPBookings
    template_name = "vistours/asp.html"

    def post(self,request):

        # Save the new booking to the database.
        if request.method == 'POST':
            form = ASPBookingsForm(request.POST)
            if form.is_valid():
                print(request.POST)
                form.save()

                # Get the data for the emails.
                asp_data = ASPBookings.objects.all()
                asp_data.contact_name = request.POST['contact_name']
                asp_data.booking_email = request.POST['email']
                asp_data.booking_date = request.POST['booking_date']
                asp_data.booking_time = request.POST['booking_time']
                asp_data.program_type =request.POST['program_type']

                # Format Date and Time
                formatted_date = parse_date(asp_data.booking_date).strftime('%A %d %B %Y')
                print(formatted_date)

                # Add SendGrid Template ID's
                BOOKING_TEMPLATE_ID = ''
                UPDATE_TEMPLATE_ID = ''

                booking_message = Mail(from_email='',to_emails=[asp_data.booking_email],)
                    
                # Add Template ID to booking message.

                booking_message.template_id = BOOKING_TEMPLATE_ID

                # Send new booking alert to VIS Staff.
                message = Mail(from_email='',to_emails='')
                    
                message.template_id = UPDATE_TEMPLATE_ID

                except Exception as e:
                    print(e.message)


            else:
                print(form.errors)
                form()
        return render(request,'vistours/success.html')

代码获取类型错误 错误 - 'TypeError' 对象没有属性 'booking_message'。

解决方法

您正在尝试在您的 except 块中打印 e.booking_message，错误很可能没有此属性？ – 伊恩·谢尔文顿 6 月 25 日 4:37
