Rails 6 + ActionCable + Stimulus example for pushing updates to the view.

This example will show how to push updates to the view for a Model instance that has changed without the user having to refresh the page.

This example focuses more on getting ActionCable working with Stimulus. If you don't already have stimulus setup in your app, here's a great write up on how to set it up: https://medium.com/better-programming/how-to-add-stimulus-js-to-a-rails-6-application-4201837785f9

Example scenario

• You have a Scan model with attributes.
• You have a ScanController#show action.
• A user is viewing a Scan through the show.html.slim|haml|erb view template.

# The following comments fill some of the gaps in Solargraph's understanding of
# Rails apps. Since they're all in YARD, they get mapped in Solargraph but
# ignored at runtime.

# You can put this file anywhere in the project, as long as it gets included in
# the workspace maps. It's recommended that you keep it in a standalone file
# instead of pasting it into an existing one.

PSQL CLI Client

Psql is a fully-fledged CLI client for Postgres, but most people are unaware of its many advanced features.

~/.psqlrc can be edited to persist any behavior or configuration settings you want between psql sessions. It behaves just like ~/.bashrc or ~/.vimrc, sourced at psql launch. See More out of psql for some interesting configurations.

If you have a long query to write and rewrite, you can use \e to edit your query in an editor.

Use \watch at the end of a query in order to automatically re-run the query every few seconds - great for monitoring while making changes elsewhere in your application architecture.
