Django Twilio Texting - django.core.exceptions.AppRegistryNotReady：尚未加载应用

我是Python和Django的新手，但已决定根据https://www.placecard.me/blog/django-wedding-website/创建自己的婚礼网站。我想要做的唯一主要区别是将电子邮件通信更改为SMS。我遇到了这个https://github.com/CleverProgrammer/CP-Twilio-Python-Text-App短信应用。

我将短信应用程序合并到一个Django项目中，以测试并尝试向数据库中的所有访客发送文本消息。我正在运行Python 3.6.5和Django 2.0.5

我的Django项目有以下目录结构。

我有以下代码：

settings.py 

import os

enter code here`# Build paths inside the project like this: 
os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)

send_sms.py： 

from twilio.rest import Client
from credentials import account_sid, auth_token, my_cell, my_twilio

client = Client(account_sid, auth_token)

my_msg = "Test message"

message = client.messages.create(to=my_cell, from_=my_twilio, body=my_msg)
然后我运行python     SMS_SEND \ send_sms.py。

这会向我的手机发送短信。

然后我添加以下内容以尝试向数据库中已有的两个guest虚拟机发送相同的消息。我做了所有的迁移。

admin.py 

from .models import SmsUser
from django.contrib import admin


class SmsUserAdmin(admin.ModelAdmin):
    list_display = ('name', 'number')
    search_fields = ['name', 'number']


admin.site.register(SmsUser, SmsUserAdmin)

models.py 

from django.db import models

class SmsUser(models.Model):

    name = models.TextField(null=True, blank=True)
    number = models.CharField(max_length=13, null=True, blank=True)

    def __str__(self):
        return ' {}'.format(self.name)

    def __str__(self):
        return ' {}'.format(self.number)

将 send_sms.py 更改为以下内容：

from twilio.rest import Client
from credentials import account_sid, auth_token, my_cell, my_twilio
from models import SmsUser

client = Client(account_sid, auth_token)

recipients = SmsUser.objects.all()

for recipient in recipients:
    client.messages.create(body='Sample text', to=recipient.number, 
from_=my_twilio)

当我再次运行python sms_send \ send_sms.py 时，我收到以下错误：

  

PS C：\ Garbage \ Python \ Django \ WebsiteSMS＆gt; python sms_send \ send_sms.py       Traceback（最近一次调用最后一次）：         文件“sms_send \ send_sms.py”，第3行，in           从模型导入SmsUser         文件“C：\ Garbage \ Python \ Django \ WebsiteSMS \ sms_send \ models.py”，第4行，                  class SmsUser（models.Model）：         文件“C：\ Users \ Gary.HIBISCUS_PC \ AppData \ Local \ Programs \ Python \ Python36-       32 \ lib \ site-packages \ django \ db \ models \ base.py“，第100行， new           app_config = apps.get_containing_app_config（模块）         文件“C：\ Users \ Gary.HIBISCUS_PC \ AppData \ Local \ Programs \ Python \ Python36-       32 \ lib \ site-packages \ django \ apps \ registry.py“，第244行，in       get_containing_app_config           self.check_apps_ready（）         文件“C：\ Users \ Gary.HIBISCUS_PC \ AppData \ Local \ Programs \ Python \ Python36-       在check_apps_ready中的32 \ lib \ site-packages \ django \ apps \ registry.py“，第127行           提升AppRegistryNotReady（“尚未加载应用程序。”）       django.core.exceptions.AppRegistryNotReady：尚未加载应用。

我已尝试过建议的答案，但未能使其正常工作。在我从send_sms.py

中的模型导入SMSUser添加之前，一切似乎都很好

我希望有人能够找出我的问题并指出我正确的方向。

答案 0 :(得分：1)

您正在尝试单独运行一个python文件，我认为这会导致您的应用失败。它正在尝试加载位于您的django项目中的 string query = "INSERT INTO test (capacity) VALUES (@capacity)"; MySqlCommand = new MySqlCommand(query, MySqlConnection); MySqlCommand.Parameters.AddWithValue("@capacity", 80.018); MySqlCommand.ExecuteNonQuery(); ，但在使用SmsUser调用该文件时无法访问。

如果要在django项目中运行此文件并能够作为命令访问模型，数据库等，可以使用django custom management commands

快速未经测试的例子：

python <dir>/<file>.py

如果设置正确，您现在可以在django项目中使用# Django holds a specific management commands path like eg.: # send_sms.management.commands.send_pending_sms_messages # which would be as a specific path send_sms/management/commands/send_pending_sms_messages.py from django.core.management.base import BaseCommand from twilio.rest import Client from credentials import account_sid, auth_token, my_cell, my_twilio from models import SmsUser class Command(BaseCommand): help = 'Send pending SMS messages' def handle(self, *args, **options): client = Client(account_sid, auth_token) recipients = SmsUser.objects.all() for recipient in recipients: client.messages.create(body='Sample text', to=recipient.number, from_=my_twilio) 作为命令运行器，如

./manage.py
