使用send_mass_mail

问题描述

我看到了很多文档和示例来创建如下所示的大量电子邮件

message1 = ('That’s your subject #1','That’s your message body #1','[e-mail]',['[e-mail]','[e-mail]'])
message2 = ('That’s your subject #2','That’s your message body #2',['[e-mail]'])
message3 = ('That’s your subject #3','That’s your message body #3',['[e-mail]'])
send_mass_mail((message1,message2,message3),fail_silently=False)

我想将大量电子邮件发送给从我的查询集返回的具有相同消息的N个用户。 我正在使用下面的代码发送大量电子邮件。但是，它非常慢，并且想知道是否存在任何有效的方法，或者由于我正在使用gmail进行测试，因此它会很慢。

def sendMasspasswordResetEmail(request):
    
    

    schoolval =  user_school.objects.filter(username=request.user.id).values_list('schoolCode',flat=True)[0]
    clsval = student_group.objects.filter(schoolCode=schoolval).values_list('classVal_id').distinct()
    student = studentclass.objects.all().prefetch_related('student_group_set__username').filter(student_group__classVal__in=clsval).distinct()
    addStudentlink = True
    #groups = student.values('student_group')
    userinschool = User.objects.filter(user_school__schoolCode=schoolval,user_type=1).values('username')
    
    html_content = render_to_string('dashboard/registration_email.html') # render with dynamic value
    text_content = strip_tags(html_content) # Strip the html tag. So people ca
    
    for recipient in userinschool:    
        subject,from_email,to = 'Account Activation xxxxx','xxxxxgmail.com.com',recipient.get('username')
        print(recipient.get('username'))       
        msg = EmailMultiAlternatives(subject,text_content,[to]) 
        msg.attach_alternative(html_content,"text/html") 
        msg.send()
    
      
    return render(request,'dashboard/add-student.html',{'students':student,'addStudentlink':addStudentlink})

由于缺乏知识，我无法为send_mass_email生成动态元组。任何帮助将不胜感激。

解决方法

您应该使用send_mass_mail来满足您的需求。

以下是操作方法的示例：

messages = ()
for item in items:  
    messages = messages + ((item.subject,item.message,item.from,[item.to]),)
send_mass_mail(messages,fail_silently=False)
