Django消息通知django-notifications-hq的使用

1、安装

pip install django-notifications-hq

2、配置

1. settings.py文件
INSTALLED_APPS = (
    'django.contrib.auth',
    ...
    'notifications',
    ...
)

2. 项目urls.py文件
import notifications.urls

urlpatterns = [
    ...
    url('^inbox/notifications/', include(notifications.urls, namespace='notifications')),
    ...
]

3、数据库迁移

python manage.py migrate notifications

4、使用

• 通常生成的通知最好在单独的信号中完成，Django有自带的信号处理方式，具体可参考Django官方文档signals章节

示例代码：

from django.dispatch import receiver
from django.db.models.signals import post_save
from comment.models import Comment
from notifications.signals import notify
from django.utils.html import strip_tags


@receiver(post_save, sender=Comment)
def send_notification(sender, instance, **kwargs):
    # 发送站内消息
    if instance.reply_to is None:
        # 评论
        recipient = instance.content_object.get_user()
        if instance.content_type.model == 'blog':
            blog = instance.content_object
            verb = '{0} 评论了你的博客《{1}》'.format(instance.user.username, blog.title)
        else:
            raise Exception('unkown comment object type')
    else:
        # 回复
        recipient = instance.reply_to
        verb = '{0} 回复了你的评论“{1}”'.format(
                instance.user.username, 
                strip_tags(instance.parent.text)
            )
    notify.send(instance.user, recipient=recipient, verb=verb, action_object=instance)

• 也可在项目任何地方生成通知

示例代码：

from notifications.signals import notify

notify.send(user, recipient=user, verb='消息内容')

• 若是但愿在消息中携带额外的数据可参考下面的步骤
  1.在项目的settings.py文件配置

  DJANGO_NOTIFICATIONS_CONFIG = {
        'USE_JSONFIELD': True,
  }

  2.发送消息时携带参数

  notify.send(instance.user, recipient=recipient, verb=verb, action_object=instance, url=url)

5、在HTML模板页面渲染

• 在页面顶部添加模板标签{% load notifications_tags %}

• 参考功能：

  • 获取未读数量

  1. 添加模板标签 {% notifications_unread as unread_count %}
  2. 使用：{{ unread_count }}

  • 所有标记为已读

  {% url 'notifications:mark_all_as_read' %}?next={% url 'userinfo' %}
  不加next参数默认返回主路由，即'/'

功能不少，这里就不一一举例，具体可参考官方文档。
