更改 Rails 命名規則 Inflector

| Comments

在 rails 當中，有許多命名的慣例

  • 像是 hello_controller 檔案，裡面慣例對應到的 Class 就是 Hello_Controller
  • 但若是像 api_controller，就會是 Api_Controller

雖然不是不行，但 API 本來就是縮寫，硬要改成 Api 可能會讓人覺得怪怪的

因此 rails 有提供解決辦法，就能夠將 api_Controller 改成 API_Controller

rails 內建有 Inflector 就是用來處理命名規則用的

config/initializers/inflections.rb

ActiveSupport::Inflector.inflections(:en) do |inflect|
  inflect.acronym 'API'
end

或是 Rails 轉單複數單字，有錯誤時，可以定義

#錯誤
"Business".singularize  => "Busines"
"moose".pluralize => "mooses"

# 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
