ruby-on-rails – 在rails上的ruby中创建带键和值的动态哈希

hash = {1 => 23.67,1 => 78.44,3 => 66.33,12 => 44.2}

像这样的1,2,12是数组索引.我希望这是可以理解的.我正在尝试使用ROR教程中的语法.@H_675_5@

像这样@H_675_5@

test = Hash.new 

  for i in 0..23
   if (s.duration.start.hour == arraY[i].hour)
     s.sgs.each do |s1|
       case s1.type.to_s
       when 'M'
         test ={i => s1.power} # here I am trying to create hash like give example in which i is for loop value
       when 'L'
         puts "to be done done"
       else
         puts "Not Found"
       end
     end
   end
 end
end

更新的代码@H_675_5@

test = Hash.new
 for i in 0..23
   if (s.duration.start.hour == arraY[i].hour)
     s.sgs.each do |s1|
       case s.type.to_s
       when 'M'
         puts s1.power;
         test[i] =  s1._power
       when 'L'
         puts "to be done"
       else
         puts "Not  Found"
       end
     end
   end
 end

结果@H_675_5@

在遍历@H_675_5@

for t in 0..array.size
  puts test[t]
end

结果：@H_675_5@

t = 68.6 # which is last value

并期待@H_675_5@

t = 33.4
t = 45.6 etc
