I have something like this:

def import\_from\_csv(csv\_file)

Item.transaction do  
FasterCSV.foreach(csv\_file.path) do |row|  
item = Item.new(:name =\> row[0], :units =\> row[1], :price =\>  
row[2])  
item.save!  
end  
end #transaction

end

If I got a negative price I want to rollback all items saved.It’s  
possible?

Sure, just raise an exception.
