Django：在提交表单时发送电子邮件

Question

用户在我的页面上提交表单后，我需要发送一封电子邮件（这仍在开发中，但很快就会投入生产）。

我已阅读此other answer，但在我提交表单后，我没有收到任何电子邮件（我已将我的个人电子邮件用作发件人和收件人，用于测试）。

我需要修改什么？

PLUS： 如何通过电子邮件发送图像？有这方面的教程吗？提交表单后我需要发送专业的电子邮件。

settings.py

EMAIL_HOST = 'smtp.gmail.com'  # since you are using a gmail account
EMAIL_PORT = 587  # Gmail SMTP port for TLS
EMAIL_USE_TLS = True

EMAIL_HOST_USER = 'oma.oma@gmail.com' #Not my actual email
EMAIL_HOST_PASSWORD = 'MyPassword' #Not my actual password

views.py：

# here we are going to use CreateView to save the Third step ModelForm
class StepThreeView(CreateView):
    form_class = StepThreeForm
    template_name = 'main_app/step-three.html'
    success_url = '/'

    def form_valid(self, form):
        form.instance.tamanios = self.request.session.get('tamanios')  # get tamanios from session
        form.instance.cantidades = self.request.session.get('cantidades')  # get cantidades from session
        del self.request.session['cantidades']  # delete cantidades value from session
        del self.request.session['tamanios']  # delete tamanios value from session
        self.request.session.modified = True
        return super(StepThreeView, self).form_valid(form)

form.py：

from django.core.mail import send_mail

class StepThreeForm(forms.ModelForm):
    instrucciones = forms.CharField(widget=forms.Textarea)
    class Meta:
        model = TamaniosCantidades
        fields = ('imagenes', 'instrucciones')

    def __init__(self, *args, **kwargs):
        super(StepThreeForm, self).__init__(*args, **kwargs)
        self.fields['instrucciones'].required = False

    def send_email(self):
        send_mail('Django Test', 'My message', 'oma.oma@gmail.com',
                  ['oma.oma@gmail.com'], fail_silently=False)

您可以在您的 Last Form 中像这样覆盖 save 方法：

 class StepThreeForm(forms.ModelForm):
      def save(self, commit=True):
          instance = super(StepThreeForm, self).save(commit=commit)
          self.send_email()
          return instance

       def send_email(self):
           image = self.cleaned_data.get('imagenes', None)
           msg = EmailMessage(
              'Hello',
              'Body goes here',
              'from@example.com',
              ['to1@example.com', 'to2@example.com'],
              headers={'Message-ID': 'foo'},
           )

           msg.content_subtype = "html"

           if image:
             mime_image = MIMEImage(image.read())
             mime_image.add_header('Content-ID', '<image>')
             msg.attach(mime_image)
           msg.send()
