Question

我正在构建一个简单的博客应用程序。我已经建立了博客并在开发服务器上运行。现在，我希望每次由我/管理员创建新博客帖子时，将邮件发送给所有订阅者。我知道要使用Django的sending_email库，但是我不知道如何自动执行该过程，即，每次创建另一个“ blog_post”对象时如何使用send_email（）自动发送电子邮件？

注意：我正在使用Django的管理界面创建新的“ blog_post”对象，因此基本上，当我“保存”该对象时，我想发送电子邮件。

我是Django的新手，任何建议，指导都会有很大帮助

以下代码： signal.py

@receiver(signals.post_save, sender=Post)
def send_post_mail(sender, instance, created, **kwargs):
    print('signal send')
    subject = "Thank you for registering with us"
    send_mail(subject, 'Body', 'sender@gmail.com', 
    ['reciever@gmail.com'], fail_silently=False,)

Models.py

class Post(models.Model):
STATUS_CHOICES = (
    ('draft', 'Draft'),
    ('published', 'Published'),
)
title = models.CharField(max_length=250)
slug = models.SlugField(max_length=250, 
                        unique = True)
author = models.ForeignKey(User,
                           related_name='blog_posts', 
 on_delete=models.CASCADE)
audio = models.URLField(max_length = 200, default = 
"spotify:episode:0Vbl7RvX3KE0lSkRmy9Wjj") 
body = models.TextField()
publish = models.DateTimeField(default=timezone.now)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)

apps.py

    from django.apps import AppConfig


   class BlogConfig(AppConfig):
         name = 'blog'


         def ready(self):
         import blog.signals

views.py

     def post_list(request):
        posts = Post.objects.order_by('-publish')
        return render(request, 'template.html', context = {'post':posts})

blog / urls.py

urlpatterns = [
#path('', views.Postlist, name='main-view'),
path('', views.get_name, name='main-form-view'),
path('<slug:slug>', views.detail_post, name='detail-post')

]

settings.py

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'sender@gmail.com'
EMAIL_HOST_PASSWORD = 'seder's account password'
EMAIL_USE_TLS = False

init.py

default_app_config = 'blog.apps.BlogConfig'

编辑：如上所示，在配置了app.py和init.py之后，它可以工作。

在与models.py相同的文件夹中创建一个名称为Signals.py的文件。
将以下导入添加到signal.py

from django.dispatch import receiver
from django.db.models import signals
from .models import Blog_post

创建方法并使用您的电子邮件库

@receiver(signals.post_save, sender=Blog_post)
def send_mail(sender, instance, created, **kwargs):
    # to test if the signal is working
    print('signal send')
    # replace it with your code once it works

在与models.py相同的文件夹中的apps.py中添加信号

from django.apps import AppConfig


class YourAppConfig(AppConfig):
    name = 'yourapp'

    # Add this to use signals
    def ready(self):
        from . import signals
