Just an FIY - this was my solution:
[code]
def self.active_record_to_array_of_hashes(array_collection,
sub_collection_names=[])
hashed_collection = []
array_collection.each do |obj|
tmp_hash = ActiveSupport::JSON.decode(obj.to_json)
#### hashify specified model association
sub_collection_names.each do |name|
if(obj.class.reflections.keys.include?(name))
tmp_hash[name] =
ActiveSupport::JSON.decode(obj.send(name).to_json)
end
end
hashed_collection << tmp_hash
end
return hashed_collection
end
[/code]
