At the top of the channel, click “Add an app”, and choose your new app. It can’t have the same name as your Slack app, so choose something else. Go to your Slack workspace and add a new channel. We now need somewhere for our app to post these blocks. join ( users ) + ' and ' + users + ' will be competing!' return Post blocks to a channel capitalize () for user in users ] if len ( users ) = 1 : #deal with grammar for a single player players = ' ' + users + ' is already in!' elif len ( users ) > 1 : players = ' ' + ', '. You only need to copy what is inside the 'blocks' key.ĭef generate_new_round_blocks (): #empty string for when there are no active players players = '' #create capitalized list of players active this round users = app_tables. We can now copy this JSON to use in a function that will generate our interactive blocks. When you’ve finished designing your Block Kit, you’ll need to change any true value in the JSON object to True. When someone interacts with this button, this action_id will be part of the request sent to our Anvil app. The button has an action_id of join_round. I built a Block Kit with a markdown ( mrkdwn) section (so that I could use emojis 😉) and a button that says “Count me in!”. On the left of the builder is what the blocks will look like in Slack and on the right, is the JSON object representing those blocks. You can play around in the Block Kit Builder to design what you want your Slack UI to look like. Slack has a nice tool that allows us to design our app’s interactivity. So we’ll also need a way for co-workers to opt-in to playing each round. As we previously agreed, scheduled fun is the best type of fun, but we can also agree that forced fun is the worst type of fun. We’ll want the app to announce to Slack that a new round of Carcassonne games are about to start, but we should also ask our co-workers if they want to play this round. The next thing we need to do is build our User Interface within Slack. Our Anvil app is set up to handle incoming message and interaction requests, and we’ve set up two Data Tables to store information about our players and games. So far, our Slack app still doesn’t do anything.
