如何使用django“Rest Framwork”发送电子邮件？

Question

I'm using small Rest api project and it works fantastic.

But somehow i have to make send email function in there.

so i added email config in settings.py like that

// settings.py

# SMTP Mail service with decouple
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = "smtp.gmail.com"
EMAIL_HOST_USER = config('EM_ACCOUNT')
EMAIL_HOST_PASSWORD = config('EM_PASSWORD')
EMAIL_PORT = 587
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

//views.py

from rest_framework import viewsets
from consult.models import Consult
from consult.serializers import ConsultSerializer
from django.core.mail import EmailMessage


class ConsultViewSet(viewsets.ModelViewSet):
    queryset = Consult.objects.all()
    serializer_class = ConsultSerializer


def send_email(request):
    email = EmailMessage(
        'Title',
        (ConsultSerializer.name, ConsultSerializer.email, ConsultSerializer.phone),
        'my-email',
        ['my-receive-email']
    )
    email.attach_file(ConsultSerializer.file)
    email.send()

// models.py

from django.db import models


# Create your models here.
class Consult(models.Model):
    name = models.CharField(max_length=16)
    position = models.CharField(max_length=16, null=True)
    group = models.CharField(max_length=50)
    email = models.CharField(max_length=50, null=True)
    phone = models.CharField(max_length=14)
    describe = models.TextField(blank=True, null=True)
    file = models.FileField(blank=True, null=True)
    create_date = models.DateTimeField(auto_now_add=True)
    update_date = models.DateTimeField(auto_now=True)

    class Meta:
        db_table = 'Consult'

// serializers.py

from rest_framework import serializers
from .models import Consult


class ConsultSerializer(serializers.ModelSerializer):
    class Meta:
        model = Consult
        fields = ('id', 'name', 'position', 'group', 'email', 'phone', 'describe', 'file', 'create_date')

Yup. that is all of my codes. And i setted send_mail function in views.

Honestly I want automatic send mail function when the consult data in my DB. but I can find only normal django explanation.

Can you help me set a automatic send mail function when data created??

Answer 1

Actually, it's better practice to use Signals instead of overriding the create() method. As an example, you can use below code in your models.py file:

@receiver(post_save, sender=settings.CONSULT_MODEL)
def send_mail_on_create(sender, instance=None, created=False, **kwargs):
    if created:
        send_email() # call send mail function

What this does is that it receives a signal when an instance of your model is created and does whatever thing you want it to. you can also change the post_save to pre_save and/or other available default signals, or even define your own signal and send it from inside the model create() function.

Method-1 : override the create() method of ConsultViewSet

def send_email():
    email = EmailMessage(
        'Title',
        (ConsultSerializer.name, ConsultSerializer.email, ConsultSerializer.phone),
        'my-email',
        ['my-receive-email']
    )
    email.attach_file(ConsultSerializer.file)
    email.send()


class ConsultViewSet(viewsets.ModelViewSet):
    queryset = Consult.objects.all()
    serializer_class = ConsultSerializer

    def create(self, request, *args, **kwargs):
        response = super(ConsultViewSet, self).create(request, *args, **kwargs)
        send_email()  # sending mail
        return response
