ActiveSupport::Inflector

Rails のバージョンアップで見かけたので調べてみる

Inflector ... 屈折する、調整するみたいな意味っぽい
-> そこから文字列をいい感じに変換するものって感じかな

The Inflector transforms words from singular to plural, class names to table names, modularized class names to ones without, and class names to foreign keys. The default inflections for pluralization, singularization, and uncountable words are kept in inflections.rb.

The Rails core team has stated patches for the inflections library will not be accepted in order to avoid breaking legacy applications which may be relying on errant inflections. If you discover an incorrect inflection and require it for your application or wish to define rules for languages other than English, please correct or add them yourself (explained below).

  • config/initializers/inflections.rb で設定するっぽい
    • ファイル内に説明が書いてある
# frozen_string_literal: true
# Be sure to restart your server when you modify this file.

# Add new inflection rules using the following format. Inflections
# are locale specific, and you may define rules for as many different
# locales as you wish. All of these examples are active by default:
# ActiveSupport::Inflector.inflections(:en) do |inflect|
#   inflect.plural /^(ox)$/i, "\\1en"
#   inflect.singular /^(ox)en/i, "\\1"
#   inflect.irregular "person", "people"
#   inflect.uncountable %w( fish sheep )
# end

# These inflection rules are supported but not enabled by default:
# ActiveSupport::Inflector.inflections(:en) do |inflect|
#   inflect.acronym "RESTful"
# end
