The Options of Rails Commands

Things you can choose to not include when creating with rails

Rails is pretty good at creating files and folder structures. In fact, it’s so good at it, I find it kind of overwhelming. With just three words ( rails new app), a new “app” directory appears, and in it, over 100 (well, exactly 101) files and folders. Run a few rails generate commands on top of that and your app’s fully expanded project tree is now taller than you. Eek.

Depending on what you’re working on, you might not want or need all of what these rails commands create. If your heart desires, you could go through after all these files and folders have been created and delete what you don’t want, but luckily, there’s a simpler way: we have options!

Rails New

When you run the rails new command in your terminal, you have a list of options to choose from. Like its name would suggest, these commands are completely optional, and the code will run fine without including them. Simply append as many as you’d like to the end of the command, and rails magic will do the rest! There are many options to choose from, but as to keep with the theme of this post, here are some of the most common files and folders you can choose to skip in the creation of a rails app, they even have their own shorthands:

For the full list of options, run rails new -h in your terminal.

Rails Generate

Like creating a new rails app, rails generators are executed in the terminal by following the above structure. A list of all the generators available can be printed by running rails g -h, where g is an alias and can be used interchangeably for generate. Here are some of the options that default to their true counterparts that you may choose to not include:

Tests

  • Available when generating: controller, generator, helper, job, mailer, model, model, resource, scaffold_controller, scaffold

Asset Options

  • Available when generating: asset, controller, resource, scaffold
  • Additionally, you can choose not to create any assets when generating a channel, controller, resource, or scaffold with the following:

Controller Options

  • Available when generating: controller, resource

Active Record Options

  • Available when generating: model, resource, scaffold

Scaffold Controller Options

  • Available when generating: scaffold, scaffold_controller

Scaffold Options

  • Only available when generating a scaffold

If you’d like to see a full list of all options for a given generator, inside of a rails app folder in your terminal, run rails g -h.
