Multiple values for the same key in a Hash

[Dominic Son]

Hi. There's got to be an easy way to do this.

I simply want multiple iteams (etc, price, quantity, and name) appended
to a key..

There's got to be a simple way (...right?)

Just add the items as an array or another container object.

Uh... Wouldn't a hash of hashes do the trick?

For example,
my_hash[:key][rice] = 1.99
my_hash[:key][:quantity] = 5
...

or

my_hash[:key] = { rice => 1.99, :quantity => 5 }

or whatever the syntax is.

Yes, i was thinking your later suggestion, but how do i iterate through
them..

the price, and quanity come back too containated (ie : 1.995 ) do i have
to mess with a .split and reg exp at this point? please say it isn't so!

Like this?

11:09:28 [~]: irbs
require 'pp' => true
Entry = Struct.newprice, :quantity, :name) => Entry
h = Hash.new {|h,k| h[k] = Entry.new} => {}
h[:foo].price = 10 => 10
h[:bar].name = "bar" => "bar"
h[:foo].name = "foo" => "foo"
pp h

{:bar=>#<struct Entry price=nil, quantity=nil, name="bar">,
:foo=>#<struct Entry price=10, quantity=nil, name="foo">}
=> nil

PS: Alternatively you can use OpenStruct.
