阵列我有这个哈希：红宝石哈希与环
{:id => [RN1223,BN3233], :name => ['Red Ring','Blue Bangles'], :category => ['Ring','Bangles']}
而且我想获得一个新的Hash以下格式：
{:id => 'RN1223', :name => 'Red Ring', :category => 'Ring'},
{:id => 'BN3233', :name => 'Blue Bangles', :category => 'Bangles'}
hsh = {:id => ['RN1223','BN3233'],
:name => ['Red Ring','Blue Bangles'],
:category => ['Ring','Bangles']}
hsh.values.transpose.map {|arr| Hash[[:id, :name, :category].zip arr]}
# => [{:id=>"RN1223", :name=>"Red Ring", :category=>"Ring"},
# {:id=>"BN3233", :name=>"Blue Bangles", :category=>"Bangles"}]
什么是你的问题？ – sawa 2015-04-02 10:16:07
我有这个散列 {：id => [RN1223，BN3233]，：name => ['Red Ring'，'Blue Bangles']，：category => ['Ring'，'Bangles']} 我想转换成这种形式 {：ID => 'RN1223'，：名称=> '红圈'，：类=> '戒指'}， {：ID => 'BN3233'，：名称=>'蓝色手镯'，：category =>'手镯'} – 2015-04-02 10:19:43
