Question

我想为批次和部门与请求的批次和部门匹配的唯一用户发送邮件。批次和部门与用户处于OneToOne关系。邮件应该从此功能发送。那邮件应该是当布尔字段is_principal为true时发送。这是我的代码。

models.py

class Rep(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    dept = models.ForeignKey(Departement, default=0)
    batch = models.ForeignKey(Batch, default=0)
    semester = models.ForeignKey(Semester, default=0)

    def __str__(self):
             return str(self.user)
class Retest(models.Model):

   semester = models.ForeignKey(Semester)
   dept = models.ForeignKey(Departement)
   batch = models.ForeignKey(Batch)
   date = models.DateField(blank=True, null=True)
   subject = models.ForeignKey(Subject)
   name = models.CharField(max_length=50)
   admnno = models.CharField(max_length=50)
   reason = models.CharField(max_length=50)
   proof = models.CharField(max_length=200)
   is_hod = models.BooleanField(default=False)
   is_principal = models.BooleanField(default=False)
   notify = models.BooleanField(default=False)
   is_sure = models.BooleanField(default=False)

   def get_absolute_url(self):
             return reverse( 'retest:retestform')
   def __str__(self):
             return self.name

views.py

def accepted(request, retest_id):

    if request.method == 'POST':
        retest.is_principal = True
        retest.save(update_fields=['is_principal'])
        email = EmailMessage('RMS', 'Your Notifications are Pending.', to=[.email])
        email.send()
return render(request, 'retest/request.html' , {'retest': retest})

如何设置地址的条件？

Answer 1

from django.core.mail import send_mail

def accepted(request, retest_id):

    if request.method == 'POST':
        retest.is_principal = True
        retest.save(update_fields=['is_principal'])

        users = [rep.user for rep in Rep.objects.filter(
            batch=retest.batch, department=retest.dept
        )]
        for user in users:
        user.email_user(subject='RMS', message='Your Notifications are Pending.')

    return render(request, 'retest/request.html' , {'retest': retest})

如果您确定您的代码100％完美且电子邮件无效。然后唱到你的邮件。然后试试。它会工作。如果您使用Gmail作为电子邮件主机，则Gmail会阻止此类操作，因为gmail不是为此而设计的。使用其他一些邮件服务，如弹性邮件或其他东西来正常工作。 Email in Django not working sometimes。你在这个qtn中也解决了同样的问题。

使用django向所选用户发送电子邮件
