troubleshooting

ActionCable - to support WebSockets, run rails g channel channel_name --assets then add mount ActionCable.server => '/cable' to config/routes.rb. update cable.yml -> production: to include the following for Heroku to connect w/ Redis for ActionCable.broadcast:

ssl_params:
    verify_mode: <%= OpenSSL::SSL::VERIFY_NONE %>

Turbo Drive lazy-loads pages following form submission, causing script tags at the bottom of following views to not always load.

<!-- add data-turbo=false to form submission buttons if the following view needs a full render -->
<button data-turbo="false" type="submit" ...>Submit</button>

Testing

# headless
bundle exec rspec # run all tests inside spec/
bundle exec rspec spec/dir_name # run all tests inside given directory

# headed (in a real browser)
HEADED=TRUE bundle exec rspec

Code Quality

clean code helps keep projects manageable as they grow in complexity.

rubocop # checks your code against Ruby styling standards and calls out issues
rubocop -A # automatically fixes issues, can lead to false negatives
rubocop -a # automatically fixes "safe" issues, less aggressive than -A (uppercase)

Rubocop is an optional feature, however it runs automatically during GitHub CI checks. if you don't want to enforce the Rubocop styleguide, simply disable the Rubocop Check step inside ci.yml.

Deploying

bundle exec figaro heroku:set -e production # you only need to do this once
heroku git:remote -a heroku_app_name_here # you only need to do this once

git push heroku master # deploys master branch
git push heroku some_branch_name:master # deploys non-master branch

If you get error: src refspec master does not match any the probable cause is that you're using a new Github repo which defaults to master being called "main." You can deploy to Heroku using the branch deployment strategy pushing main over master:

git push heroku main:master

or update your Heroku account to also default to main and then deploy with:

git push heroku main

note: Heroku must have 2 'dynos' enabled, web + worker, to process background jobs. if you don't need a queue, simply remove the worker task from Procfile and don't invoke .delayed functions.

Mailers

Speedrail is configured for transactional mailers by Postmark, which costs $10 /month for 10k emails. to activate this, set postmark_api_token inside application.yml and then verify your sending domain.

if you prefer a free email service for low volume applications, consider Resend. before installing it, first uninstall Postmark from Speedrail by 1) removing gem 'postmark-rails' from the Gemfile, 2) running bundle, then 3) deleting the following lines from application.rb:

config.action_mailer.delivery_method = :postmark
config.action_mailer.postmark_settings = { api_token: ENV['POSTMARK_API_TOKEN'] }
