Question

在这里我有一个视图，该视图将向选定的用户发送电子邮件或删除选定的用户。删除选定的用户工作正常，但向选定的用户发送电子邮件却无法正常工作。我尝试了这些方法将电子邮件发送到选定的电子邮件。第一种方法

Exception Type: AttributeError
Exception Value:    
'str' object has no attribute 'email'

如果电子邮件发送给用户，我也想从会话中删除选定的用户，然后重新启动会话，这在此代码中不会发生

第二种方法是说invalid email address。

第一种方法

def selected_users(request):
    selected_users = get_user_model().objects.filter(id__in=request.POST.getlist('users'))

#tring to store selected users in session
    initial = {'users':[]}
    session = request.session.get('users',initial)
    if selected_users:
        for user in selected_users:
            session['users'].append(user.email)
            request.session['users'] = session
            print('hello',request.session['users']) # here i want to restart session either email sends or not to the user
    if selected_users and  request.method == 'POST' and 'delete_selected' in request.POST:
            selected_users.delete()
            messages.success(request, 'deleted')
            return redirect('view_users')
    elif request.method == 'POST' and 'mail_selected' in request.POST:
            form = SendMailForm(request.POST or None)
            config = EmailConfiguration.objects.order_by('-date').first()
            backend = EmailBackend(host=config.email_host, port=config.email_port, username=config.email_host_user,
                                   password=config.email_host_password, use_tls=config.email_use_tls)
            if form.is_valid():
                sub = form.cleaned_data['sub']
                msg = form.cleaned_data['msg']
                for user in request.session['users']:
                    email = EmailMessage(subject=sub, body=msg, from_email=config.email_host_user, to=[user.email],
                                             connection=backend)
                    email.send()
                    messages.success(request, 'Your mail sent.')
                    return redirect('view_users')

            return render(request, 'send_mail_selected.html', {'users': selected_users,'form':form})

    else:
            messages.error(request, 'Invalid request')
            return redirect('view_users')

    msg = forms.CharField(widget=forms.Textarea)

Answer 1

您已将电子邮件地址而非用户对象存储在列表中。因此，您应该直接使用它们：

for email in request.session['users']:
    email = EmailMessage(subject=sub, body=msg, from_email=config.email_host_user, to=[email], connection=backend)
