[Nitro] Help creating a ObjectGraph adapter for RubyAMF

# Will always return an array if there are results, nil if there is no
# result.  Array contents are always .kind_of?(Og::Model)
result = SomeModel.find()

# will return return a .kind_of?(Og::Model) or nil if nothing found
result = SomeModel.find_one()

So yes, you can rely on result[0].kind_of?(Og::Model) if somethings has
been found.

Ah of course.  :P  As you can get the class from the object.  :)

if result[0].kind_of?(Og::Model)
   result[0].class.serializable_attributes
end
