# Based on this code: https://github.com/hotwired/turbo-rails/blob/main/app/controllers/turbo/frames/frame_request.rb
# the response of turbo_frame_request? is based on the presence of a header named "Turbo-Frame".
# Therefore, you can exercise code behind this conditional in your controller tests by specifying that header in your GET requests.

# example controller action
class DashboardController < ApplicationController
  # GET dashboard
  def index
    if turbo_frame_request?
      # frame loading behavior

For a while, my org was using Wordpress to manage a public-facing website, which was reverse-proxied on my Rails application's server to share its DNS (a fairly common setup). However, the cost of supporting Wordpress and the proxy became too great to justify, and we looked into replacing Wordpress with another CMS option. I came across SpinaCMS, an open-source, Rails-powered CMS, which offered a lot of upside to proxying to a seperate server running a separate application. However, there were several gotchas that took some navigating, that I want to share in one place, considering I believe these would all be common situations to anyone trying to accomplish a similar goal. This guide will assume you have completed the basic setup of gem installation and setup rake tasks.

Using MySQL instead of Postgres

If your application is already running on MySQL, you probably don't want to go through the hurdles of moving to a Postgres database. Fortunately, unless you are using the e-commer

So you're running a Rails application and want to spruce up your YARD documentation. Here's the guide I wish I had.

Step 0: Plugin

Add yard-activerecord and yard-activesupport-concern to your Gemfile, add --plugin activerecord and --plugin activesupport-concern to your .yardopts flags, and db/schema.rb to the end of your .yardopts sources. Your models' attributes and assocations should now be included in the documentation.

Step 1: CSS/JS

To modify your YARD template, create doc-src/templates/default/fulldoc/html, then add --template-path doc-src/templates to your project's .yardopts. You can now create a doc-src/templates/default/fulldoc/html/css/common.css and the styles will be included (but overwrites need to be !important).
