如何允许/白名单具有非常不规则(无法声明)结构的深层嵌套哈希。例子:{"widgets"=>[{"id"=>75432,"conversion_goal_id"=>1331,"options"=>{"form_settings"=>{"formbuilder-bg-color"=>"rgba(255,255,255,0)","font-size"=>"14px","form-field-depth"=>"42px"},"linkedWidget"=>""},"type"=>"formbuilder-widget"},{"id"=>75433,"conversion_goal_id"=>
我一直在看maxmethod在Ruby的Enumerable混合(v2.4.1)。这是一个相当简单的方法,但是当存在重复项时它如何排序项目有点令人困惑。例如:x=[1,2,3,4,5,6,7,8,9]x.max{|a,b|a%2b%2}=>110.times{|y|px.max(y){|a,b|a%2b%2}}[][1][1,7]#whyis7thenextelementafter1?[3,1,5]#whynomore7?[7,3,1,5]#7isnowfirst[9,7,3,1,5][9,7,3,1,5,6][9,7,3,1,5,4,6][9,7,3,1,5,2,4,6][9,7,5
