Singular or Plural? A Cheatsheet for Ruby on Rails Generators

scrabill profile image Shannon Crabill Originally published at shannoncrabill.com on ・1 min read

Ruby on Rails (Rails) is good at doing the manual work for you. With one line, Rails can create the model, controller and view files associated with your application. The downside of using rails generate or its shortcut rails g is that small mistakes like typos are amplified. If Rails is expecting user, and you mistakenly typed users it could cause functionality errors.

This cheat sheet will help to avoid those conflicts.

If you are comfortable working with Rails, Model–view–controller (MVC) architecture rails generate, this post is for you.

Noun Singular? Plural? Example
Controller No Yes users_controller.rb, products_controller.rb
Migrations / Tables No Yes 001_create_users.rb, 002_create_products.rb
Model Yes No user.rb, product.rb
Routes No Yes :users, :products
Seed Data No Yes seeds.rb
Scaffold Yes No rails g scaffold user
View No Yes /users, /products

Update

The above chart was updated on February 15th 2020 to include scaffolds. Thank you timnans for the suggestion! The table was also put into alphabetical order by noun.

You could also add the 'scaffold' to the cheetsheet

 

This is a good idea! The chart has been updated to include scaffold!

 

This is information I cannot remove from my memory.

 
 

It's join table naming that always trips me up.
