A find to key pair

I would like to get an array/hash where I can write @image[88] and that would result in "thisimage.jpg". I've got:

@images = Image.find(:all, :select => "id, real_file_name") result = {} @images.map {|a| result[a.id] = a.real_file_name }

I think this is correct, but I don't know how to get the result from it. It doesn't work with @images[88]. What am I doing wrong?

There may be a more railsey way, but this is a basic Ruby way that should work

@images = Image.find(:all, :select => "id, real_file_name") @image_map = {} # <--- should be a better name for this @images.each do |this_image|    @image_map.store(this_image.id, this_image.real_file_name) end

@image_map[some_id]
