求助： Ruby 数组运用的问题

我谢了一小段代码

@item_pack = []
@pack1 = []
model_pack = {:name => {},:modellist =>[]}
data_pack = {:model =>{},:date =>[] }

model_pack[:name] = 1
data_pack[:model] = "aaa"
model_pack[:modellist] << data_pack

model_pack[:name] = 2
data_pack[:model] = "bbb"
model_pack[:modellist] << data_pack


@item_pack << model_pack

puts "#{@item_pack}"

本来意图输出是

[{:name=>2, :modellist=>[{:model=>"aaa", :date=>[]}, {:model=>"bbb", :date=>[]}]}]

但是实际输出的是

[{:name=>2, :modellist=>[{:model=>"bbb", :date=>[]}, {:model=>"bbb", :date=>[]}]}]

请问问题点在哪里？新手求教
