Ruby:从数组中选择一个哈希

Question

我有以下数组:

response = [{"label"=>"cat", "name"=>"kitty", "id"=>189955}, {"label" => "dog", "name"=>"rex", "id" => 550081}]

如何选择包含标签cat的哈希？我知道response.first会给我相同的结果,但我想搜索by标签.

谢谢!

Answer 1

response.find {|x| x['label'] == 'cat' } #=> {"label"=>"cat", "name"=>"kitty", "id"=>189955}

Answer 2

尝试:

response.select { |x| x["label"] == "cat" }
