django - 从外键（特别是 UserProfile）查询数据

Question

如果我有一个模型，其中有几个从 UserProfile 模型继承的字段：

class LeaveRequest(models.Model):
    employee = models.ForeignKey(UserProfile)
    supervisor = models.ForeignKey(UserProfile, related_name='+', blank=False, null=False)
    submit_date = models.DateField(("submit date"), default=datetime.date.today)
    leave_type = models.CharField(max_length=64, choices=TYPE_CHOICES)
    start_date = models.DateField(("start date"))
    return_date = models.DateField(("return date"))
    ...

我使用这个模型来创建一个模型表单：

class LeaveRequestForm(ModelForm):
    class Meta: 
        model = LeaveRequest

如何在用户配置文件中查询电子邮件 url？在此视图功能中，我正在尝试向发件人（员工）和主管发送有关表单提交的通知电子邮件：

def create_request(request):
    if request.method == 'POST':
        form = LeaveRequestForm(request.POST)
        if form.is_valid():
            name = form.cleaned_data['employee']
            subject = form.cleaned_data['leave_type']
            message = form.cleaned_data['notes']
            sender = form.cleaned_data['employee']

            remoterq = form.save(commit=False)
            remoterq.save()
            form.save_m2m()
            recipients = [user.email for user in remoterq.employee, user.email for user in remoterq.supervisor]
            from django.core.mail import send_mail
            send_mail(subject, message, 'projects.xxx@google.com', recipients, fail_silently=False)
            return HttpResponseRedirect('.')

我的“收件人”变量代码无效，但我不知道如何修复它。

Answer 1

尝试

remoterq.employee.user.email

对于员工电子邮件和

remoterq.supervisor.user.email

对于主管电子邮件。
