你如何瀏覽一組鍵和值對，然後將它們分配給一個新的Hash對象？

Question

array = Array.new 
y = Hash.new 
x = Hash.new 
y["First"] = "Moses" 
y["Last"] = "Kim" 
x["First"] = "John" 
x["Last"] = "Snow" 
array.push(y) 
array.push(x) 

p array 



hash = Hash.new 
hash['listing'] = Hash.new 
y = array.each do |a| 
    a.each do |key,value| 
    hash['listing'][key] = value 
    end 
end 

p hash 

我想數據是這樣的：

{ listing: { First: Moses, Last: Kim}, { First: John, Last: Snow}} 

Answer 1

{ listing: { First: Moses, Last: Kim}, { First: John, Last: Snow}}無效。

子哈希需要在一個數組： { listing: [{ First: Moses, Last: Kim}, { First: John, Last: Snow}]}

這可以從你構建代碼：

array = Array.new 
y = Hash.new 
x = Hash.new 
y["First"] = "Moses" 
y["Last"] = "Kim" 
x["First"] = "John" 
x["Last"] = "Snow" 
array.push(y) 
array.push(x) 
{ listing: array } 

或者只是 { listing: [x, y]}
