如何在django表单中通过电子邮件发送会议邀请？

from django import forms

class MeetingForm(forms.Form):
    email = forms.EmailField(label='Email')

from django.core.mail import send_mail
from django.shortcuts import render

def send_invitation(request):
    if request.method == 'POST':
        form = MeetingForm(request.POST)
        if form.is_valid():
            email = form.cleaned_data['email']
            subject = '会议邀请'
            message = '您被邀请参加会议。'
            sender = 'your_email@example.com'
            recipient_list = [email]
            send_mail(subject, message, sender, recipient_list)
            return render(request, 'success.html')
    else:
        form = MeetingForm()
    return render(request, 'invitation.html', {'form': form})

<form method="post" action="{% url 'send_invitation' %}">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">发送邀请</button>
</form>
