	collection = ActiveSupport::Inflector.tableize(name)
	"#{collection}/#{element}".freeze
   end
end

.autoload_object(rid) ⇒ Object

Either retrieves the object from the rid_store or loads it from the DB.

Example:

ActiveOrient::Model.autoload_object "#00:00"

The rid_store is updated!

Todo: fetch for version in the db and load the object only if a change is detected

Note: This function is not located in ModelClass since it needs to use @@rid_store

.use_or_allocate(rid) ⇒ Object

Based on the parameter rid (as “#a:b” or “a:b”) the cached value is used if found. Otherwise the provided Block is executed, which is responsible for the allocation of a new dataset

i.e.

ActiveOrient::Model.use_or_allocated my_rid do
    ActiveOrient::Model.orientdb_class(name: raw_data['@class']).new raw_data
end
