Question

我有一个哈希，其数据类似于：

details = [{
  :project_name=>"ABC", :project_id=>12345, :total_count=>1, 
  :stories=>[#<TrackerApi::Resources::Story id=987654>]
}, {
  :project_name=>"XYZ", :project_id=>54321, :total_count=>1, 
  :stories=>[#<TrackerApi::Resources::Story id=123456>]
}]

我想插入另一个包含数据的数组，如：

sorter_Version = [["Abc ", "30 August 2017"], ["Not Accepted", "30 August 2017"]]

详细哈希，但不知何故无法做到。有人可以帮帮我。谢谢你。

输出应该是：

details = [{
      :project_name=>"ABC", :project_id=>12345, :total_count=>1, 
      :stories=>[#<TrackerApi::Resources::Story id=987654>],
      :sorter_version=>["Abc ","30 August 2017"]
    }, {
      :project_name=>"XYZ", :project_id=>54321, :total_count=>1, 
      :stories=>[#<TrackerApi::Resources::Story id=123456>],
      :sorter_version=>["Not Accepted ","30 August 2017"]
    }]

只需使用each_with_index：

details.each_with_index { |d, i| d[:sorter_version] = sorter_Version[i] }
#=> [{:project_name=>"ABC", :project_id=>12345, :total_count=>1, 
#     :stories=>["#<TrackerApi::Resources::Story id=987654>"], 
#     :sorter_version=>["Abc ", "30 August 2017"]}, 
#    {:project_name=>"XYZ", :project_id=>54321, :total_count=>1, 
#     :stories=>["#<TrackerApi::Resources::Story id=123456>"], 
#     :sorter_version=>["Not Accepted", "30 August 2017"]}]

不可变版本：

details.map.with_index { |d, i| d.merge(sorter_version: sorter_Version[i]) }
