django-slack-utils

Django-slack-utils is helper application to handle Slack requests.

It supports verification through HTTP_X_SLACK_SIGNATURE and HTTP_X_SLACK_REQUEST_TIMESTAMP.

Installation

Add the following to your settings.py

INSTALLED_APPS = [
    ...
    'slack_utils',
]

SLACK_SIGNING_SECRET = 'your signing secret from Slack'

Add the following to your urls.py

    from django.conf.urls import include
    from django.urls import path
    
    urlpatterns = [
        ...
        path('slack/', include('slack_utils.urls')),
    ]

Usage

View decorator

The @slack_view decorator adds CSRF exempt and verification to your function-based django view.

from slack_utils.decorators import slack_view
from django.http import HttpResponse

@slack_view
def sample_view(request, *args, **kwargs):
    # your logic
    return HttpResponse("Hello!")

Class-based view

The SlackView base class adds CSRF exempt and verification to your class-based django view.

from slack_utils.views import SlackView
from django.http import HttpResponse

class SampleView(SlackView):
    def post(self, request, *args, **kwargs):
        # your logic
        return HttpResponse("Hello!")

Slash commands

To handle Slack slash commands, point the command URL to /slack/commands/.

Now just add a handler function to slack.py module of your app.

from slack_utils.decorators import slack_command

@slack_command('/test')
def test_command(text, **kwargs):
    # your logic
    return "Hello!"     # or {'text': "hello!"}

**kwargswould get the rest of the data from Slack request

Events API

Point Slack events API to the /slack/events/.

Subscription can be done in two ways:

Receiver decorator

Put them into slack.py of your app or make sure it's loaded once.

from slack_utils.decorators import slack_receiver

@slack_receiver('reaction_added')
def on_reaction_added(event_data, **kwargs):
    # your logic 
 

Signal

from slack_utils.signals import event_received
from django.dispatch import receiver

@receiver(event_received)
def on_event_received(sender, event_type, event_data, **kwargs):
    if event_type == 'reaction_added':
        # your logic 

    # your other logic
