python - Django Forms 和 'tuple' 对象没有属性 'rsplit' 错误

Question

我花了好几天的时间试图弄清楚这个问题，但绝对碰壁了。我已经研究并阅读了有关此问题的所有 SO 帖子，但最终还是需要一些帮助。

我正在尝试连接一个简单的联系表单，下面是我提交表单时抛出相同的 'tuple' object has no attribute 'rsplit' 错误 的代码的最新版本。

我的Django版本是1.9，使用的是Python3.5

def contact(request):
    title = 'Contact Us'
    title_align_center = True
    form = ContactForm(request.POST or None)

    if form.is_valid():
        form_email = form.cleaned_data.get('email')
        form_message = form.cleaned_data.get('message')
        form_full_name = form.cleaned_data.get('full_name')
        subject = 'Site Contact Form'
        from_email = settings.DEFAULT_FROM_EMAIL
        recipient_list = [from_email, 'charles@studiorooster.com']
        message = '%s: %s via %s' % (
            form_full_name,
            form_message,
            form_email)
        # some_html_message = ''' <h1>hello</h1> '''

        email = EmailMessage(
            subject,
            message,
            form_email,
            recipient_list,
            ['roosteromg@gmail.com'],
            reply_to=[from_email],
            headers={'Reply-To': from_email},
        )
        email.send()

    context = {
        'form': form,
        'title': title,
        'title_align_center': title_align_center,
    }
    return render(request, 'pages/contact.html', context)

Answer 1

然后问题出在您的 settings.py 文件中，默认邮件设置，正如您在回溯中看到的那样，EMAIL_BACKEND 设置可能是问题所在。

这些设置应该是这样的:

EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'youremail@gmail.com'
EMAIL_HOST_PASSWORD = 'yourpassword'
EMAIL_PORT = 587
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL =  'youremail@gmail.com'
