Rails console tips, tricks and customizations

问题

There's this great post on irb tricks, but what about further customizing Rails console behavior and output?

Awesome print and Hirb are great.

SQL logging is a must for me. In your ~/.irbrc paste:

require 'logger'
ActiveRecord::Base.logger = Logger.new(STDOUT) if defined?(Rails)

What's your tip/trick/gem of choice?

I've recently written a rails specific console tweaks blog post: https://rbjl.janlelis.com/49-railsrc-rails-console-snippets (as gist)

Open last migration in your editor quickly! Assuming you already open your editor with a command like atom . to open the project root in atom, you can do:

atom $(echo "db/migrate/$(ls db/migrate | tail -1)")

Of course you can replace atom with subl etc. You can easily alias this to a function. I keep things like this in ~/.functions which load in my shell.

last_migration() {
        atom $(echo "db/migrate/$(ls db/migrate | tail -1)")
}

Then you can later create migrations and open them in 1 go:

rails g migration create_some_migration_name && last_migration
