Hi,

I am looking at ActiveRecord Extension

[http://www.continuousthinking.com/tags/arext/rdoc/index.html](http://www.continuousthinking.com/tags/arext/rdoc/index.html)

as a way of helping me synchronize data from a csv file. I have the  
app working using row by row query, but the bulk upload looks like it  
will help speed things up. There is also mention of a synchronize  
method. But I have only found limited documentation.

If anyone has any pointers to some docs, or some information on how  
bulk upload and synchronise work I would be grateful. Will synhronize  
allow me to send multiple rows in one hit and have the table updated  
where there are changes, and can I control the direction of changes,  
ie. csv to db.

thanks  
Tonypm
