railsで数値を3桁で区切る。「delimited」メソッドで解決

Posted at

数字を3桁で区切る方法を解決しましたので備忘録として。
例:1000 → 1,000

#仕様
Rails 5.1.7
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux]

#やりたいこと
productsテーブルのpriceカラムを表示させたいです。
↓productsテーブル

#「delimited」メソッドで解決

sample.html
<%= product.price.to_s(:delimited)%>
#例 => 12,345,678

#「delimiter」オプションで任意の文字で桁を区切れます。

sample.html
<%= product.price.to_s(:delimited, delimiter: "あ")%>
#例 => 12あ345あ678
