Hi

I’ve got 2 static functions (self.),  
playlist function is calling check\_movie function in a loop.

I need to have the results stored in myarray and myhash.

I don’t know how I can give references of myarray and myhash to  
check\_movie function so myarray and myhash are updated and not emptied  
everytime I loop.

def self.playlist  
myarray = new Array  
myhash = new Hash

Movie.find(:all).each do |movie|  
check\_movie(movie,myarray,myhash)  
end

#use of myarray and myhash

end

def self.check\_movie(movie,myarray,myhash)  
#fill myarray, fill myhash  
end

---

return them

def self.playlist  
myarray = new Array  
myhash = new Hash

Movie.find(:all).each do |movie|  
myarray,myhash = check\_movie(movie,myarray,myhash)  
end

#use of myarray and myhash

end

def self.check\_movie(movie,myarray,myhash)  
#fill myarray, fill myhash

return myarray,myhash  
end
