我正在使用Ruby on Rails 3.2.2,我想"轻松"/"快速"地将散列键从Symbols 更改为Strings.也就是说,从{:one => "Value 1", :two => "Value 2", ...}到{"one" => "Value 1", "two" => "Value 2", ...}.
Symbol
String
{:one => "Value 1", :two => "Value 2", ...}
{"one" => "Value 1", "two" => "Value 2", ...}
如何通过尽可能少地使用代码来实现？
ruby hash ruby-on-rails ruby-on-rails-3
hash ×1
ruby ×1
ruby-on-rails ×1
ruby-on-rails-3 ×1
