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.

For each Ruby module/class, we have Ruby methods on the left and the equivalent
Clojure functions and/or relevant notes are on the right.

For clojure functions, symbols indicate existing method definitions, in the 
clojure namespace if none is explicitly given.  clojure.contrib.*/* functions can
be obtained from http://github.com/kevinoneill/clojure-contrib/tree/master,
ruby-to-clojure.*/* functions can be obtained from the source files in this
gist.

If no method symbol is given, we use the following notation:

Azure SDK for Go and Azure REST API examples

This document details how to create credentials to use when making Azure REST API calls or when using the Azure SDK for Go.

I created this gist because my Golang app was returning empty results and when using the REST API I would see this error message:

{
    "error": {
        "code": "AuthorizationFailed",
        "message": "The client '3c470957-xxxxxx' with object id '3c470957-xxxxxx' does not have authorization to perform action 'Microsoft.Resources/resources/read' over scope '/subscriptions/3dcd5fea-zzzzzz' or the scope is invalid. If access was recently granted, please refresh your credentials."
