ruby-on-rails - 如何在哈希中创建哈希

Question

我如何能够在一个散列中创建一个散列，嵌套的散列有一个键来识别它。还有我在嵌套哈希中创建的元素，我怎样才能拥有它们的键

例如

test = Hash.new()

#create second hash with a name?? test = Hash.new("test1")??
test("test1")[1] = 1???
test("test1")[2] = 2???

#create second hash with a name/key test = Hash.new("test2")???
test("test2")[1] = 1??
test("test2")[2] = 2??

谢谢

Joel's 是我会做的，但也可以这样做:

test = Hash.new()
test['test1'] = Hash.new()
test['test1']['key'] = 'val'
