Ruby on Rails: how to check pluralized and single form of names

问题

I have created a model Anonymous with command

rails g model Anonymous section_id:integer aid:string fake:bool active:bool

but table name in the migration is called anonymous

class CreateAnonymous < ActiveRecord::Migration
  def change
    create_table :anonymous do |t|
      t.integer :section_id
      t.string :aid
      t.bool :fake
      t.bool :active

      t.timestamps
    end
  end
end

Am i right that pluralized form of Anonymous is Anomymous too ? (English is not my native language). How can i see what pluralized names Rails gives to my models ? Something like rake routes ?

回答1:

You can do this in the rails console.

$ "anonymous".pluralize
=> "anonymous" 

or another example where the plural word is different.

$ "cookie".pluralize
=> "cookies" 

回答2:

pluralize(count, singular, plural = nil) public

Attempts to pluralize the singular word unless count is 1. If plural is supplied, it will use that when count is > 1, otherwise it will use the Inflector to determine the plural form

Examples:

pluralize(1, 'person')
# => 1 person

pluralize(2, 'person')
# => 2 people

pluralize(0, 'person')
# => 0 people

for you

"anonymous".pluralize

I'd just rename your model. Save yourself the pain and future debugging and just avoid this potential headache. You could use "Anonymouse" with plural "Anonymouses". Or think up a more clever name.
