# Discord cardiParty webhook

This is a simple webhook to push new cardiParties into the cardiParty channel.

## install

1. Create and activate [virtual env](https://docs.python.org/3/library/venv.html)
2. Install requirements: `pip install -r requirements.txt`
3. Set up a cronjob
    1. set the env values (see below)
    2. set a time to run e.g. every 30 mins
    3. set the command listed below under "Cron job command"
4. Test cronjob works
5. Relax

## How it works

We run this on the newcardigan wordpress server.

1. With a cron job we call the civiCRM API use `cv` to grab the details of the latest cardiParty
2. We pipe that string into a python script
3. The script checks a custom RSS feed for new parties
4. If no new party, end
5. 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

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`)

## Cron job command

```sh
cv api4 Event.get '{"select":["title","address.city","start_date","summary"],"join":[["Address AS address","LEFT",["loc_block_id.address_id","=","address.id"]]],"orderBy":{"start_date":"DESC"},"limit":1}' | ./webhook.py
```
This should pipe a string like this into the script:

```
[{"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 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.
