Question

我的意图是每次将短信发送到我的服务器时，服务器应通过数据库查看sms中的数字是否已经是存储对象，如果不是则创建并将对象保存到数据库中我做错了吗？

views.py

from django.http import request
from django_twilio.decorators import twilio_view
from django_twilio.request import decompose
from twilio.twiml.messaging_response import MessagingResponse
from .models import Contacts

@twilio_view
def sms_choice(request):
    twilio_request = decompose(request)
    contact_num = twilio_request.from_
    contact_info = ['Thanks for your subscription', 
                    "How old are you?", "Annual Income?"]
    response = twilio_request.body
    resp = MessagingResponse()
    subscribers = [Contacts.objects.all()]
    for contact in subscribers:
        if contact_num != contact.customer_number:
            b = Contacts(customer_number=contact_num)
            b.save()
            resp.message(contact_info[0])
        elif contact_num == contact.customer_number:
            resp.message(contact_info[1])

    print(contact_num, response)
    return str(resp)

models.py

from django.db import models


class Contacts (models.Model):
    customer_number = models.CharField(max_length=15)
    customer_age = models.CharField(max_length=4,
                                    null=True)
    customer_income = models.CharField(max_length=10,
                                       null=True)

    def __unicode__(self):
        return self.customer_number

您似乎有两种情况：在第一种情况下，您的数据库中不存在联系号码，因此您要回复消息1;在第二种情况下，联系号码确实存在，因此您要回复消息2。

因此，您应该检查是否有该号码的记录，如果没有，请创建它。确切地说有一个快捷方式：get_or_create。

resp = MessagingResponse()
contact, created = Contacts.objects.get_or_create(customer_number=contact_num)
if created:
    resp.message(contact_info[0])
else:
    resp.message(contact_info[1])
    # I presume you want to update the customer age here
    contact.age = response
    contact.save()
return resp
