arrays - 遍历对象数组

Question

我有一个对象数组，并试图减少到特定形式的数组。例如：

[
  #<Item name: "Item 1", content: #<Item value: #<Item quantity: val1>, #<Item 
quality: val2>>,
  #<Item name: "Item 2", content: #<Item value: #<Item quantity: val1>, #<Item 
quality: val2>>,
  #<Item name: "Item 3", content: #<Item value: #<Item quantity: val1>, #<Item 
quality: val2>>,
  #<Item name: "Item 4", content: #<Item value: #<Item quantity: val1>, #<Item 
quality: val2>>,
  #<Item name: "Item 5", content: #<Item value: #<Item quantity: val1>, #<Item 
quality: val2>>
]

应该减少到

[ [Item1, [val1, val2]], [Item2, [val1, val2]], [Item3, [val1, val2]], [Item4, 
[val1, val2]], [Item5, [val1, val2]]]

我努力了

arr1 = []
arr2 = []
array.each do |array|
 arr1 << array.name
  arr2 << array.value.quantity
   arr2 << array.value.quality
   arr1 << arr2
 end

上面代码的输出是

[ Item1,  [val1,val2,val1,val2,val1,val2,val1,val2,val1,val2,val1,val2], 
Item2, [[val1,val2,val1,val2,val1,val2,val1,val2,val1,val2,val1,val2]....]

这段代码的问题它不会停止每个对象的迭代，我的意思是对于 Item1，它应该只有 val1 和 val2 仅适用于 Item1。

Answer 1

我会从这样的事情开始：

array.map do |element|
  [element.name, [element.value.quantity, element.value.quality]]
end
