如何将send_mail发送给Django中的用户组？

Question

我想向拥有顾问权限的所有用户发送电子邮件： perms.profiles.consultant_permission

我的代码如下：

model.py

 class Profile(models.Model):
    //some attributes

    class Meta:
         permissions = (
             ('consultant_permission', 'Consultant Permission'),
         )

view.py

consultant_msg_html = render_to_string('email/consultant_review_email.html', context)
send_mail("Register sent to review", 
    consultant_msg_html, 
    registration.consultant.email, 
    [registration.consultant.email,], 
    html_message=consultant_msg_html, 
    fail_silently = False)

我怎样才能做到这一点？

Answer 1

首先，您需要获得具有特定权限的所有用户：

from django.contrib.auth.models import User, Permission
from django.db.models import Q

perm = Permission.objects.get(codename='consultant_permission')  
users = User.objects.filter(Q(groups__permissions=perm) | Q(user_permissions=perm) ).distinct()
recipients = list(i for i in users.values_list('email', flat=True) if bool(i))

然后，您可以在send_email()中使用recipients。
