Python(Django) - 将 URL 从 post 转换为嵌入的 YouTube IFrame

Question

基本上我想要实现的是在 post 中找到 URL，例如如果我 post 这个：

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
https://www.youtube.com/watch?v=example

它将如下所示： Lorem ipsum pain sit amet, consectetur adipiscing elite, 因为 eiusmod tempor incididunt out labor and pain magna aliqua.

models.py:

from django.db import models

class NewsFeed_Articles(models.Model):
    title = models.CharField(max_length = 120) 
    post = models.TextField()
    date = models.DateTimeField()

def __str__(self):
    return self.title

post.html:

{% extends "Feed/wrapper.html" %}

{% block content %}

  <div class="card">
  <h2 class="text-info">{{newsfeed_articles.title}}</h2>
  <h6 class="text-info">{{newsfeed_articles.date|date:"d-m-Y в H:i:s"}}</h6>
  <p>{{newsfeed_articles.post|safe|linebreaks}}<p>
  <div class="fakeimg" style="height:200px;">Image</div>
  </div>

{% endblock %}

使用代码将 YouTube 网址转换为 YouTube 嵌入：

import re

def convert_ytframe(text):
  _yt = re.compile(r'(https?://)?(www\.)?((youtu\.be/)|(youtube\.com/watch/?\?v=))([A-Za-z0-9-_]+)', re.I)
  _frame_format = '<iframe width="560" height="315" src="https://www.youtube.com/embed/{0}" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>'
  
  def replace(match):
    groups = match.groups()
    return _frame_format.format(groups[5])
  return _yt.sub(replace, text)

这是您可以自己测试的工作示例：repl.it/@themisir/AromaticAvariciousMarketing
此外，您可以在此处测试正则表达式：regex101.com/r/97yhSH/1

代码已简化。

import re

yt_link = re.compile(r'(https?://)?(www\.)?((youtu\.be/)|(youtube\.com/watch/?\?v=))([A-Za-z0-9-_]+)', re.I)
yt_embed = '<iframe width="560" height="315" src="https://www.youtube.com/embed/{0}" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>'

def convert_ytframe(text):
  return yt_link.sub(lambda match: yt_embed.format(match.groups()[5]), text)
