One subject I miss in the book is reports. Good ones, with many lines, breaks, totals and so on. Is there any good gem or plugin for it? Something like JasperReports/iReport. If doesn´t, would be nice if we have some tips about how to integrate Rails and iReport. Or some other free software. I´ve found something on the internet but too confuse. It´s easyer understand my wife wishes than how to implement it.
