How it works

We run this on the newcardigan wordpress server.

With a cron job we call get_party.sh
The shell script set env values and uses the civiCRM API using cv to grab the details of the latest cardiParty
We pipe that string into webhook.py
The script checks a custom RSS feed for new parties
If no new party, end
If new party,
1. save the guid to latest_post.txt for the next round of checking
2. use the image and title from the RSS feed and the details from the cv API call
3. publish via a webhook to Discord

env values

These are all set in get_party.sh, not in crontab. Because we need most of them in a subsequent call (either inside cv or in webhook.py) we export them all.

We need to include some secrets via environment values:

channel is the channel ID (DISCORD_CHANNEL) token is the secret token for the webhook (DISCORD_TOKEN) cardiparty_ping is the ID of the @cardiParty ping role (DISCORD_CARDIPARTY_PING)

There are also a couple of other things we need to do: civicrm_settings - set CIVICRM_SETTINGS so that cv can find it venv - we need to activate the venv using source <path/to/venv>

Cron job command

*/15 * * * * cd /home/cardigan/rss-discord-bot && ./get_party.sh

get_party.sh should pipe a string like this into webhook.py:

[{"id":108,"title":"Melbourne Art Library","address.city":"Melbourne","start_date":"2024-04-06 16:30:00","summary":"Melbourne Art Library (MAL) is a not-for-profit lending library that collects specialised art and design texts. They are proudly independent and are curious about what being a 'library' means."}]

RSS feed

The rss feed is https://newcardigan.org/category/cardiparties/?feed=cardipartyfeed.

This special cardipartyfeed is a slightly modified RSS2 feed. The only thing it does differently is filter out everything that isn't a cardiparty ,and include the featured image in an enclosure so that we can pick it up directly from the feed. See the newcardigan WordPress theme for how this works.
