I have found recently that rake db:migrate
will add the new migrations for both development environment and test environment but for a rollback it only undoes the development version. So to do both I do.
rake db:rollback STEP=1
RAILS_ENV=test rake db:rollback STEP=1

Use AR::Relation#exists instead of AR::Relation#count / #empty? for faster DB query
(#empty? use #count behind unless loaded)

One “pattern”/trick I learned at a job that keeps my code clean - use a module method to generate paths to external libraries (e.g., Javascript, CSS)… (code simplified below)
module LibraryHelper
def handlebars_javascript
'https://#{cdn_path_to_library}'
end
end
then in your application layout file:
<%= javascript_include_tag handlebars_javascript, :application %>
