Ruby on rails 3 访问嵌套散列中的数据

首先，我在这里使用这个文件：

初始化后

my_profile=贪婪：：profile：：Career.new'rwk#1242'

我得到一个这样的数组

当我尝试这样访问它时

我的英雄，它回来了

[{"name"=>"Ziyi", "id"=>10692899, "level"=>60, "hardcore"=>false, "paragonLevel"=>87, "gender"=>1, "dead"=>false, "class"=>"wizard", "last-updated"=>1354337248}, {"name"=>"Aerendil", "id"=>5987778, "level"=>60, "hardcore"=>false, "paragonLevel"=>0, "gender"=>1, "dead"=>false, "class"=>"demon-hunter", "last-updated"=>1353389408}, {"name"=>"Bubba", "id"=>9177617, "level"=>60, "hardcore"=>false, "paragonLevel"=>11, "gender"=>0, "dead"=>false, "class"=>"witch-doctor", "last-updated"=>1352946041}, {"name"=>"Emma", "id"=>7153459, "level"=>60, "hardcore"=>false, "paragonLevel"=>0, "gender"=>1, "dead"=>false, "class"=>"monk", "last-updated"=>1347863170}, {"name"=>"Grumbar", "id"=>17793743, "level"=>60, "hardcore"=>false, "paragonLevel"=>0, "gender"=>0, "dead"=>false, "class"=>"barbarian", "last-updated"=>1352944313}, {"name"=>"BankerOne", "id"=>12215739, "level"=>1, "hardcore"=>false, "paragonLevel"=>0, "gender"=>1, "dead"=>false, "class"=>"monk", "last-updated"=>1351810350}] 

{"name"=>"Ziyi", "id"=>10692899, "level"=>60, "hardcore"=>false, "paragonLevel"=>87, "gender"=>1, "dead"=>false, "class"=>"wizard", "last-updated"=>1354337248} 

如果我先走一步，使用我的_profile.heromes[0]，它就会返回

[{"name"=>"Ziyi", "id"=>10692899, "level"=>60, "hardcore"=>false, "paragonLevel"=>87, "gender"=>1, "dead"=>false, "class"=>"wizard", "last-updated"=>1354337248}, {"name"=>"Aerendil", "id"=>5987778, "level"=>60, "hardcore"=>false, "paragonLevel"=>0, "gender"=>1, "dead"=>false, "class"=>"demon-hunter", "last-updated"=>1353389408}, {"name"=>"Bubba", "id"=>9177617, "level"=>60, "hardcore"=>false, "paragonLevel"=>11, "gender"=>0, "dead"=>false, "class"=>"witch-doctor", "last-updated"=>1352946041}, {"name"=>"Emma", "id"=>7153459, "level"=>60, "hardcore"=>false, "paragonLevel"=>0, "gender"=>1, "dead"=>false, "class"=>"monk", "last-updated"=>1347863170}, {"name"=>"Grumbar", "id"=>17793743, "level"=>60, "hardcore"=>false, "paragonLevel"=>0, "gender"=>0, "dead"=>false, "class"=>"barbarian", "last-updated"=>1352944313}, {"name"=>"BankerOne", "id"=>12215739, "level"=>1, "hardcore"=>false, "paragonLevel"=>0, "gender"=>1, "dead"=>false, "class"=>"monk", "last-updated"=>1351810350}] 

{"name"=>"Ziyi", "id"=>10692899, "level"=>60, "hardcore"=>false, "paragonLevel"=>87, "gender"=>1, "dead"=>false, "class"=>"wizard", "last-updated"=>1354337248} 

但是，我无法从上述结果中获取更多数据

my_profile.heroes[0]。name返回NoMethodError，my_profile.heroes[0][0]返回“nil”

我做错了吗

提前谢谢

这是一个杂烩；使用哈希语法：

my_profile.heroes[0]['name']

除非有什么东西用访问器方法包装了一个哈希，否则它只是一个哈希。

它是一个哈希，你试过使用哈希语法吗？@Dave-hash=my_profile，然后hash[：heroes]返回NoMethodError

my_profile.heroes[0]['name']

，不知道你想用

hash[:heroes]

做什么。哇！真不敢相信这么简单！一直在上下寻找解决方案！谢谢
