Django Slack

  • Djangobot is a bridge between Slack and a Channels-enabled Django app. Specifically, it is a protocol server that produces and consumes messages for channels-based apps. It is built atop autobahn and twisted.
  • I wanted to make my Django app send debugging information to slack instead of by email, which is the default. Disabling email is simple. Just don't put any emails in ADMINS setting Sending informa.

Django is a widely-used Python webapplication framework with a 'batteries-included' philosophy. The principlebehind batteries-included is that the common functionality for buildingweb applications should come with the framework instead of as separatelibraries.

Django is a free web application framework, written in Python.

For example,authentication,URL routing, atemplate engine,an object-relational mapper (ORM),and database schema migrationsare all included with the Django framework.Compare that included functionality to the Flask framework which requires aseparate library such asFlask-Loginto perform user authentication.

The batteries-included and extensibility philosophies are simply two differentways to tackle framework building. Neither philosophy is inherently betterthan the other one.

Django is an implementation of the web frameworks concept. Learn how these pieces fit together in the web development chapter or view the table of contents for all topics.

Why is Django a good web framework choice?

The Django project's stability, performance and community have growntremendously over the past decade since the framework's creation. Detailedtutorials and good practices are readily available on the web and in books.The framework continues to add significant new functionality such asdatabase migrationswith each release.

I highly recommend the Django framework as a starting place for new Python webdevelopers because the official documentation and tutorials are some of thebest anywhere in software development. Many cities also have Django-specificgroups such as Django District,Django Boston andSan Francisco Djangoso new developers can get help when they are stuck.
