在Django开发的项目中如何用'@'提及/标记用户 [英] how to mention/tag users with '@' on a django developed project

问题描述

我正在尝试实现在诸如twitter之类的社交网站上使用的 @功能，以在django项目中标记或提及用户。举例来说，单击 @stack应该转到堆栈的个人资料。

I am trying to implement the "@" feature used on social sites such as twitter to tag or mention users on my django project. Say for example, "@stack" when clicked should go to stack's profile.

该如何操作对我有帮助。

How to do that would be helpful to me.

推荐答案

在编辑器中处理的提及系统正确吗？这是 django-markdown-editor 谁提供直接提及用户 @ [用户名] => @username

The mention system handled on editor right? Here is django-markdown-editor who providing to direct mention user @[username] => @username

另请参见函数 markdown_find_mentions ，如果您需要为其他用户提到的用户实施通知系统，例如stackoverflow，则很有用。

see also about function markdown_find_mentions, useful if you need to implement the notification system for user mentioned by another users, something like stackoverflow.

def markdown_find_mentions(markdown_text):
    """
    To find the users that mentioned
    on markdown content using `BeautifulShoup`.

    input  : `markdown_text` or markdown content.
    return : `list` of usernames.
    """
    mark = markdownify(markdown_text)
    soup = BeautifulSoup(mark, 'html.parser')
    return list(set(
        username.text[1::] for username in
        soup.findAll('a', {'class': 'direct-mention-link'})
    ))

，这是一个简单的流程； p>

and this a simply flow process to do;

1. 创建评论/帖子/等时，找到提到的所有用户并创建通知。


2. 何时编辑commemnt / post / etc，查找提到的所有新用户并创建通知。

通知具有发送者和接收者。

Makesure the Notification have a sender and receiver.

class Notification(TimeStampedModel):
    sender = models.ForeignKey(User, related_name='sender_n')
    receiver = models.ForeignKey(User, related_name='receiver_n')
    content_type = models.ForeignKey(ContentType, related_name='n', on_delete=models.CASCADE)
    object_id = models.PositiveIntegerField()
    content_object = GenericForeignKey('content_type', 'object_id')
    read = models.BooleanField(default=False)

    ....
