Django app for sending notifications.

Project description


Latest PyPI version Python versions

A templated Django messaging library


  1. pip install django-ilmoitin

  2. Add django_ilmoitin to INSTALLED_APPS.

  3. Run migrations

    python migrate ilmoitin


  1. django-ilmoitin uses django-mailer to send emails, so you need to configure the MAILER_EMAIL_BACKEND setting to let django-mailer know, how to actually send the mail:

    MAILER_EMAIL_BACKEND = "your.actual.EmailBackend"
  2. Define default from address in settings

    DEFAULT_FROM_EMAIL = "Ilmoitin <>"

    In case you need translated from addresses, those can be defined like

       "fi": "Yrjö <>",
       "en": "George <>",

    The value from DEFAULT_FROM_EMAIL will be used for languages not defined in that dict.

  3. Create a file in django app and register your notification types:

    from django_ilmoitin.registry import notifications
    notifications.register("event_created", "Event created")
    notifications.register("event_deleted", "Event deleted")
  4. Create a file in django app and add dummy context data. Either use the codes of notifications that you registered in the previous step, or use the const COMMON_CONTEXT to make some variables available for all templates:

    from django_ilmoitin.dummy_context import COMMON_CONTEXT, dummy_context
    from .models import MyModel
    my_object = MyModel(foo="bar")
        COMMON_CONTEXT: {"my_object": my_object},
        "event_created": {
            "foo": "bar"
        "event_deleted": {
            "fizz": "buzz"
  5. Import notifications and dummy context in your

    from django.apps import AppConfig
    class ExampleConfig(AppConfig):
        name = "example"
        def ready(self):
            import example.notifications
            import example.dummy_context
  6. Go to django admin and add notification templates to your notifications

  7. Send notifications. List of attachment files can be passed as last optional argument:

    from django_ilmoitin.utils import send_notification
    context = {
        "foo": "bar",
    attachment = "test.txt", "foo bar", "text/plain"
    send_notification("", "event_created", context, [attachment])
  8. By default, notifications will be sent immediately, if you only want to add notification to the message queue and send it later, configure ILMOITIN_QUEUE_NOTIFICATIONS:


Using the GraphQL API

The package provides an optional GraphQL API that requires a working graphene API to work, and it needs additional dependencies.

  1. To install them, run: pip install django-ilmoitin[graphql_api]

  2. Add the Query to the entrypoint where you build your schema:

# my_app/
import django_ilmoitin.api.schema as django_ilmoitin_schema

class Query(
    # other extended classes

Code format

This project uses black for Python code formatting. We follow the basic config, without any modifications. Basic black commands:

  • To let black do its magic: black .
  • To see which files black would change: black --check .

Troubleshooting guide

  1. Cannot receive email even though it was sent successfully
  • Some strict spam filter might mark email as spam if its Message-ID header has suspicious domain name (e.g 158431519447.10.15335486611387428798@qa-staging-i09m9b-staging-77bd999444-p2497)

  • This is because Python tries to generate messsage id base on the FQDN of the local machine before sending email . Fortunately most of Email Sending services (Mailgun, MailChimp, Sendgrid,..) have a way to generate a reliable message-id that will likely pass spam filter, so we better let them do it.

  • If you are using django-anymail as the email backend, there is an easy way to remove the auto-generated Message ID using pre_send signal

  • Example:

    from anymail.signals import pre_send
    def remove_message_id(sender, message, **kwargs):
        message.extra_headers.pop("Message-ID", None)

Note that it only works if you are using django-anymail as your email backend
