Question

How should I name my models when they need to be named after a word which ends with “s” (link Bus, for example)? I suppose rails will pluralize it putting another “s” to end of the word. But I’d like my table to be called “buses” instead of “buss”.

Answer 1

Rails will handle this for you by using String#pluralize when generating models:

% rails g model bus                                                                                                                                                                            
      invoke  active_record
      create    db/migrate/20130205170847_create_buses.rb
      create    app/models/bus.rb
      invoke    rspec
      create      spec/models/bus_spec.rb

And the resulting migration:

# ...
    create_table :buses do |t|
      t.timestamps
    end
# ...

You can try it yourself in rails c too:

[1] pry(main)> 'bus'.pluralize
=> "buses"
[2] pry(main)> 'miss'.pluralize
=> "misses"
[3] pry(main)> 'kiss'.pluralize
=> "kisses"
