python – 当有人评论他们的帖子时,如何使用django-notification通知用户

我已经在django开发了一段时间了,并开发了一个整洁的网站,其功能包括撰写博客,发布问题,共享内容等.但是仍然有一件事情遗失,即为用户创建通知.

我想要做的是在用户的个人资料中告知用户,无论何时有人评论他们的帖子,或者他们是否关注某个帖子并且有更新,然后通知用户该更新.我查看了很多应用程序,但我仍然对如何做到这一点感到很困惑.

在使用django通知的情况下,我似乎有一个印象(这可能是错误的),我只能通过电子邮件通知用户,即我无法在用户个人资料中显示这些通知,就像我们在Facebook上一样.

首先我想知道我是不是错了,然后我真的需要一些适当的教程或指导如何去做.我知道如何注册通知并将其发送到正确的信号,但是没有关于如何在模板中显示这些通知的文档,如果可以的话.

任何指导/教程/入门文档将深表感谢.

解决方法:

是的django-notifications仅适用于电子邮件通知.

这是一个信号槽,您可以将其添加到models.py并根据自己的需要进行调整：

from django.db import models
from django.contrib.sites.models import Site
from django.db.models import signals
from notification import models as notification

def create_notice_types(app, created_models, verbosity, **kwargs):
    notification.create_notice_type("new_comment", "Comment posted", "A comment has been posted")
signals.post_syncdb.connect(create_notice_types, sender=notification)

def new_comment(sender, instance, created, **kwargs):
    # remove this if-block if you want notifications for comment edit too
    if not created:
        return None

    context = {
        'comment': instance,
        'site': Site.objects.get_current(),
    }
    recipients = []

    # add all users who commented the same object to recipients
    for comment in instance.__class__.objects.for_model(instance.content_object):
        if comment.user not in recipients and comment.user != instance.user:
            recipients.append(comment.user)

    # if the commented object is a user then notify him as well
    if isinstance(instance.content_object, models.get_model('auth', 'User')):
        # if he his the one who posts the comment then don't add him to recipients
        if instance.content_object != instance.user and instance.content_object not in recipients:
            recipients.append(instance.content_object)

    notification.send(recipients, 'new_comment', context)

signals.post_save.connect(new_comment, sender=models.get_model('comments', 'Comment'))

现在用于模板,非常简单.

模板/通知/ new_comment / short.txt

{{ comment.user }} commented on {{ comment.object }}

模板/通知/ new_comment / notice.html

<a href="{{ comment.user.get_absolute_url }}">{{ comment.user }}</a> commented <a href="{{ comment.content_object.get_absolute_url }}">{{ comment.content_object }}</a>

模板/通知/ new_comment / full.txt

{{ comment.user }} commented on {{ comment.content_object }}

Comment:
{{ comment.comment }}

Reply on: 
http://{{ site.domain }}{{ comment.content_object.get_absolute_url }}

警告：这是对我们的生产代码的非常简化的,未经测试的改编.

注意：Django-1.7弃用了post_syncdb信号
