I want to schedule the email send for some choosen date . How can I do that in DRF?

Question

I want to take the receiver email address and schedule date as an input and send mail to the schedule date. I have following lines of code in views.py Actually I'm looking forward to use apscheduler package for async background task in django but any suggestions and solutions are appreciable.

class SendMailView(APIView):

    def post(self, request, *args, **kwargs):

    '''
    POST Method for sending Email
    '''     
       send_to = request.data.get('receiver_email') 
       schedule_for = request.data.get('schedule_date')

       email_plaintext_message = " Hello"
       send_mail(
                # title:
                "Test mail,
                # message:
                email_plaintext_message,
                # from:
                 'some@gmail.com,
                # to:
                [send_to]

            )


       return Response({"status":"Email Send"},status=status.HTTP_200_OK)

Consider using Celery. All you need to do is follow the installation, start a worker and the beat, with that you can scheduler tasks.

task.py

from celery import shared_task

@shared_task
def sendScheduledEmail(email_to):
   #do your stuff

And on your API POST you schedule that:

sendScheduledEmail.apply_async([email_to],eta=datetime.datetime(2021, 07, 06, 09, 30))

I didnt test this, so let me know if you get any errors
