tkawa / filter_params.rb

Created July 11, 2013 07:57

https://gist.github.com/tkawa/4745785 の件、FormBuilder(form_forみたいなやつ)がいらなければ、gemなくてもこんなふうに書けばすむというメモ。

	class FilterParams < ActionController::Parameters
	include ActiveModel::Model

	validates :date, format: /\A\d{4}-\d{2}-\d{2}\Z/
	validates :q, length: { maximum: 20 }

	def initialize(params = {})
	params.reverse_merge!(per: '10')
	super(params)
	end

http://example.com/posts?date=2013-01-01&q=search_word&page=2&per=20 のように、クエリパラメータでフィルタするような場合に、 strong parameters と併用して、 filter_params に default とか validate とか書けるgemを作成中ですがどうでしょう？ https://github.com/tkawa/collection_filter/tree/auto-params

	-# クエリパラメータもform_forと同じように書ける
	= filter_form do \|f\|
	= f.label :date
	= f.text_field :date
	= f.label :q
	= f.search_field :q
	= f.button

Railsでlocaleの翻訳が見つからなかったとき、“translation missing”はログに出して、viewにはhumanizeした文字列を出す

	# config/initializers/i18n_exception_handler.rb
	I18n.exception_handler = ->(exception, locale, key, options) do
	if exception.is_a?(I18n::MissingTranslation)
	Rails.logger.warn exception.message if Rails.env.development?
	key.to_s.split('.').last.humanize
	else
	raise exception
	end
	end
