I have to import some csv files into the database. Each file had a
corresponding model and table in the system.
So I was thinking that there will be some common methods for all the
importers (log, spent_time_in_miliseconds, run, ...) and some non common
methods (convert_line_to_parameters, ...). Some common methods will end up
calling particular methods (i.e. run will call convert_line_to_parameters
for each line in the csv file).

I'm new to Ruby so the first idea that I got in mind was using one abstract
class and the create one class for each model that has to be imported.
Then I realize that didn't look like a Ruby way to solve this problem. My
second thought was to create a module with all the common methods and
include that module in the different importers, but not sure its the best
way either.

It will be great to get some ideas from people with more experience to get
this done in the best way.

Thanks in advance.
