Hi, Bruno,

     I'm not too sure if I fully understood you, but this shouldn't be too
difficult in constructing the data structure, but quite of bit mind-blogging
for sure...

   Just make an array of hashes of arrays...a room array, such as

arrRoom = [ "0",
                  {"person"=>[day1, day2,...],  # this is for room1,
arrRoom[1]
                  { #ditto for room2, arrRoom[2] } ]


Then based on the return value of your "view" method, you can do this:

# 1
view_method(day1).each do |person, room|

     arrRoom[room]["person"]<<day1
end

#2
view_method(day2).each do |person, room|

     arrRoom[room]["person"]<<day2
end

(The above looks like it needs some code refactoring)

and finally, just run an each_loop on the arrRoom, and deference
all the hashes to get your result:

arrRoom.each do |room|
   next if arrRoom[0]
   arrRoom[room][person].each do |day|
       #  puts arrRoom[room] + arrRoom[room][person][day] + \
       #  arrRoom[room][person]

# The above "puts" is not absolutely correctly, you need to re-structure
other "persons" into account...

   end
end
__END__


Hopefully this pseudo code helps you thinking along the line...
