How do I sort an array of hashes by a value in the hash?4个
@cases => [{"name"=>"25 Cases per 60 day","count"=>0},{"name"=>"30 Cases for 60 days","count"=>8},{"name"=>"10 Cases per 60 days","count"=>5}]
如果我有一个包含先前结果的对象,我如何按DESC顺序排序？
为了得到我做的实例变量案例@H_403_6@
ClassName.all.collect{|e| {'name' => e.name,'count' => e.contracts.count}}
