ActiveRecord::Migration table.references() ignores ActiveRecord::Base.pluralize_table_names = false

[erikj]

It appears that in Rails / ActiveRecord 4.2.1, that the references column "type" ignores ActiveRecord::Base.pluralize_table_names or doesn't work as expected when configured to false:

$ grep plural config/environment.rb
ActiveRecord::Base.pluralize_table_names = false

$ rails generate model foo
      invoke  active_record
      create    db/migrate/015_create_foo.rb
      create    app/models/foo.rb
      invoke    minitest
      create      test/models/foo_test.rb
      create      test/fixtures/foos.yml

$ rails generate model bar foo:references
      invoke  active_record
      create    db/migrate/016_create_bar.rb
      create    app/models/bar.rb
      invoke    minitest
      create      test/models/bar_test.rb
      create      test/fixtures/bars.yml

$ cat db/migrate/015_create_foo.rb
class CreateFoo < ActiveRecord::Migration
  def change
    create_table :foo do |t|

      t.timestamps null: false
    end
  end
end

$ cat db/migrate/016_create_bar.rb
class CreateBar < ActiveRecord::Migration
  def change
    create_table :bar do |t|
      t.references :foo, index: true, foreign_key: true

      t.timestamps null: false
    end
  end
end

$ rake db:migrate
...
