可以在django中将视图生成的pdf附加到电子邮件消息中吗？

from django.http import HttpResponse
from django.core.mail import EmailMessage
from django.template.loader import render_to_string
from django.conf import settings
from io import BytesIO
from reportlab.pdfgen import canvas

def generate_pdf():
    # 使用ReportLab生成PDF
    buffer = BytesIO()
    p = canvas.Canvas(buffer)
    p.drawString(100, 100, "Hello World")
    p.showPage()
    p.save()
    buffer.seek(0)
    return buffer

def send_email_with_pdf(request):
    # 生成PDF
    pdf_buffer = generate_pdf()

    # 创建电子邮件消息
    email_subject = "PDF Attachment"
    email_body = render_to_string('email_template.html', {'message': 'Please find the attached PDF.'})
    email = EmailMessage(email_subject, email_body, settings.DEFAULT_FROM_EMAIL, ['recipient@example.com'])

    # 将PDF附加到电子邮件消息中
    email.attach('document.pdf', pdf_buffer.getvalue(), 'application/pdf')

    # 发送电子邮件
    email.send()

    return HttpResponse("Email sent with PDF attachment.")
