概要
Hash#reject
詳細
Hashから条件に一致しない要素を抽出する
サンプルコード
# encoding: utf-8 require 'tbpgr_utils' h = { hoge_key1: :hoge_value, hoge_key2: :hoge_value, hige_key: :hige_value, hage_key: :hage_value, } bulk_puts_eval binding, <<-EOS h.reject {|k, v|v == :hoge_value} h.reject {|k, v|v == :not_exists} EOS __END__ 下記はTbpgrUtils gemの機能 bulk_puts_eval https://rubygems.org/gems/tbpgr_utils https://github.com/tbpgr/tbpgr_utils
出力
h.reject {|k, v|v == :hoge_value} # => {:hige_key=>:hige_value, :hage_key=>:hage_value}
h.reject {|k, v|v == :not_exists} # => {:hoge_key1=>:hoge_value, :hoge_key2=>:hoge_value, :hige_key=>:hige_value, :hage_key=>:hage_value}
