I want to mimic the functionality that Gmail has, where you can choose to send an email at a certain time (maybe 3:34 am tomorrow) in Django.
I looked at something like django-crontab
(https://pypi.org/project/django-crontab/).
I came up with an idea to use django-crontab
to achieve this:
This feels a bit hacky and over-engineered. Is there a better way? Thanks!
You can check out celery and how to integrate it with django. Once done, task scheduling is easy,first add your gmail configuration in settings.py as follows:
EMAIL_BACKEND = 'django_smtp_ssl.SSLEmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'your_email'
EMAIL_HOST_PASSWORD = 'your password'
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER
EMAIL_PORT = 465
Then in your tasks.py you can add the function for scheduling emails as follows:
from django.template.loader import render_to_string
from django.core.mail import EmailMessage
@periodic_task(
run_every=(crontab(hour=3, minute=34)), #runs exactly at 3:34am every day
name="Dispatch_scheduled_mail",
reject_on_worker_lost=True,
ignore_result=True)
def schedule_mail():
message = render_to_string('app/schedule_mail.html')
mail_subject = 'Scheduled Email'
to_email = getmail
email = EmailMessage(mail_subject, message, to=[to_email])
email.send()
Then finally your email template 'schedule_mail.html'
{% autoescape off %}
Hello ,
This is a test email
if you are seeing this, your email got delivered!
Regards,
Coding Team.
{% endautoescape %}
And the command to run celery service as beat:
celery -A yourapp beat --loglevel=info
replace 'yourapp' with name of your app. Cheers!!
