Helpful debugging trick:

When running a focused test, sometimes it's useful to log the SQL generated by the test. Stick the following in your test:

ActiveRecord::Base.connection.instance_variable_set :@logger, Logger.new(STDOUT)

Rerun your focused test and bask in the loveliness that is your test's SQL.

Recently, I had a staging database on Heroku that was running on the Ronin database (which was originally the lowest-sized DB you could get at Heroku). Since they added two new options, Crane and Kappa, we wanted to take advantage of the cost savings. Here's how you can migrate your Ronin DB to Crane (or any other plan).

The old database was named BROWN while the new one is CRIMSON. You can determine this by running:

heroku pg:info --app myapp-staging

1. Add Crane database

    heroku addons:add heroku-postgresql:crane --app myapp-staging
   

heroku pg:wait --app myapp-staging
