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?

Answer:

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.
