Django如果ckeditor上的图片被删除，如何删除服务器上的图片

from django.shortcuts import render
from django.conf import settings
from bs4 import BeautifulSoup
import os

def delete_deleted_images(request):
    if request.method == 'POST':
        content = request.POST.get('content', '')  # 假设表单中的字段名为content
        soup = BeautifulSoup(content, 'html.parser')
        deleted_images = []

        # 提取被删除的图片URL
        for img in soup.find_all('img'):
            img_url = img.get('src')
            if img_url not in content:
                deleted_images.append(img_url)

        # 删除服务器上的图片文件
        for img_url in deleted_images:
            img_path = os.path.join(settings.MEDIA_ROOT, img_url)
            if os.path.exists(img_path):
                os.remove(img_path)

    return render(request, 'delete_deleted_images.html')
