slacktools-commands

A simple framework for working with Slack slash-commands (https://api.slack.com/interactivity/slash-commands).

Register you custom Command class with the ComandFactory and when you receive a command request from Slack simply grab the command instance from the factory and execute it.

Install

pip install slacktools-commands

Basic Usage

Define your command:

from commands import register_command, Command, CommandValidationError

from myproject import get_status, post_status


@register_command("/status")
class StatusCommand(Command):
    def _validate(self):
        if not get_status(id=self.payload.text):
            raise CommandValidationError("Not a valid id.")

    def _execute(self):
        post_status(id=self.payload.text)

Handle the Slack command request:

from rest_framework.views import APIView
from rest_framework.response import Response

from commands import CommandFactory

class CommandsView(APIView):
    def post(self, request):
        command = CommandFactory.make_commmand(request.data)
        command.execute()
        return Response()

Action Commands

Action commands allow you execute many different actions from a single Slack command. The text following the command is used to determine which action should be performed. The text is split by spaces, the first character set determines the action and the remain character sets are passed to the action as options/parameters.

Example

The below class definitions will handle the following command: /status service api

from commands import ActionCommand, Action, CommandValidationError, register_command

from myproject import post_status_msg


class ServiceStatus(Action):
    def validate(self):
        if len(self.options) == 0:
            CommandValidationError(self.payload, "Missing service name")

    def execute(self):
        post_status_msg(self.options[0])


@register_command("/status")
class StatusCommand(ActionCommand):
    ACTIONS = {
        "service": ServiceStatus
    }
