More Rails Features

Flashcard 5 of 8

Similar to the previous question, whenever generating a new rails app the first things we end up doing are switching the database settings to use Postgres, replacing test-unit with rspec, and removing Turbolinks. Is there any way to automate all of this?

We can use the ~/.railsrc file to configure a set of default arguments we want used whenever we run rails new. The following is an example railsrc file that alters some defaults:

--skip-test-unit
--skip-bundle
--database=postgresql
--skip-turbolinks

We can use any options that could be used with the rails new command in our ~/.railsrc file. Run rails new --help to see the full list of arguments.

If you're looking for a more full featured Rails app generator then be sure to check out Suspenders, our app generator that handles all of the above and also updates the Gemfile, configures the stylesheets to our liking, pre-configures Hound and CircleCI, and a whole bunch more.
