This is about 30% faster than using a standard bulk insert (eg: ar-extensions import)

all it does is:
– take a list of columns and a 2D Array with the column values
– create a tempfile and put a csv representation of the data in it
– call mysql’s LOAD DATA INFILE against the temp file

Acts As Authorizable is a part solution for providing pseudo-hierarchical role based authorizations on ActiveRecord model instances using your existing database table relationships. It is designed to eliminate the need for deep nesting controllers due to authorization. That being said, it is only part of a total authorization mechanism.
