How to setup Postoffice via django commands
Now we are ready to start sending messages to postoffice
. But first, we must generate topics
and/or publishers
in postoffice depending on the purpose of the project with postoffice.
If we need to create the topics to be able to publish, we should execute:
$ ./manage.py configure_postoffice_topics
and, if we need to create the publishers, we should execute:
$ ./manage.py configure_postoffice_publishers
Sending messages to postoffice
We have the publish
method from the publishing
module
from postoffice_django.publishing import publish
publish(topic: str, message: dict, **attributes: dict) -> None
-
topic
: Topic name. This topic must exist on postoffice to manage the message. -
message
: Message to be sent. This must be a dict. -
