ruby issue : mixing Hash and Array

I have been trying to set up an hash without any success ::
here is what I tested (I splitted it to detail my understanding or
error...)

 h = {"2008" => []}     => {"2008"=>[]}
 months = Array.new(12, [])     => [[], [], [], [], [], [], [], [],
[], [], [], []]

 h[''2008''] = months  => => [[], [], [], [], [], [], [],
[], [], [],
[], []]

 days = Array.new(31, 1)
=> [1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,
1, 1, 1, 1, 1, 1, 1, 1, 1]
irb(main):005:0> h[''2008''][2][15] = 1
=> 1
irb(main):006:0> h[''2008'']
=> [[nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil,
nil, nil, 1], [nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil,
nil, nil, nil, nil, 1], [nil, nil, nil, nil, nil, nil, nil, nil, nil,
nil, nil, nil, nil, nil, nil, 1], [nil, nil, nil, nil, nil, nil, nil,
nil, nil, nil, nil, nil, nil, nil, nil, 1], [nil, nil, nil, nil, nil,
nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, 1], [nil, nil, nil,
nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, 1], [nil,
nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil,
1], [nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil,
nil, nil, 1], [nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil,
nil, nil, nil, nil, 1], [nil, nil, nil, nil, nil, nil, nil, nil, nil,
nil, nil, nil, nil, nil, nil, 1], [nil, nil, nil, nil, nil, nil, nil,
nil, nil, nil, nil, nil, nil, nil, nil, 1], [nil, nil, nil, nil, nil,
nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, 1]]

h[''2008''][2][15]
=> 1

it seems that the 1 is set in ALL months arrays not ONLY in [2]
I would like to have a 2 dimensional array ( 12 months 0-11 x 31 days
0-31) , with all values set to 0  and being able to
set the status of a specific date to 1 , (creating the hash for the
year if it''s not already existing)

ex : date   2008, November 8
will create  a  hash with key ''2008'' and an array (12x31)
where
h[''2008''][10][7] = 1

ex : date   2008, November 15
will modify  the  array (12x31) at  h[''2008''][10][7] =  1
( h[''2008''] already exist)

 date   2009, December 24
will create  a  hash with key ''2008'' and an array (12x31)
where
h[''2009''][11][23] = 1

is ther a simpler way to do it ?

thanks for your advices

This is an Array with 12 copies (references) to the same empty array.   
You probably want to use the block form for the initialization:
   months = Array.new(12) { [] }
or
   months = Array.new(12) { Array.new }
> h[''2008''] = months  => => [[], [], [], [], [], [],
[], [], [], [],
> [], []]
This could have been inlined as:

   h = {''2008'' => Array.new(12){[]} }

(if you don''t mind the punctuation train in there)

> 1, 1, 1, 1, 1, 1, 1, 1, 1]
This is the same, but since 1 is a Fixnum and they are "special" by  
virtue of being an immediate value, each element is actually its own  
value.

Did you forget a step?  h[''2008''][2] = days

Wow, you''re asking a bunch of different things.  Let''s break
them down:

* creating the hash for the year if not already existing

That''s possible using the block form of Hash initialization. 
Let''s
assume that there will be a method called empty_year which gives you  
the 12x31 array of 0 (even though I suspect you''ll really want nil  
rather than 0).

   h = Hash.new {|h,k| h[k] = empty_year }

* a 2 dimensional array ( 12 months 0-11 x 31 days 0-31)

Well, that''s a 12x32 array if you want to index by the day number, but
anyway...  Let''s wrap that up in our empty_year method:

   def empty_year
     Array.new(12) { Array.new(31) { 0 } }
   end

(and you''d have to put the definition of empty_year earlier than the  
initialization of the Hash)

* and being able to set the status of a specific date to 1

Hmm.. You skip over how you get from "2008 November 8" to the index  
values so let''s tackle that one first:

   require ''date''
   d = Date.parse(''2008 November 8'')

Now you can:

   h[d.year.to_s][d.month - 1][d.day - 1] = 1

Whoa!  That''s ugly.  Perhaps we need a method on h that let''s
us hide
those details.

   def h.add_date(parseable_date)
     d = Date.parse(parseable_date)
     self[d.year.to_s][d.month-1][d.day-1] = 1
     self
   end

Then we can just do:

   h.add_date(''2008 November 15'')

You could define a class called, say, Calendar, that had add_date as  
an instance method, too.

If you put all of this together (in irb), you get:

$ irb
irb> require ''date''
=> true
irb> def empty_year
irb>         Array.new(12) { Array.new(31) { 0 } }
irb>       end
=> nil
irb> h = Hash.new {|h,k| h[k] = empty_year }
=> {}
irb> def h.add_date(parseable_date)
irb>   d = Date.parse(parseable_date)
irb>   self[d.year.to_s][d.month-1][d.day-1] = 1
irb>   self
irb>   end
=> nil
