Master/detail report with Rails and Ireport/JasperReports

Hi all,
has anyone made it already?

Rafael,
I and some other sad people I’ve met tried to make this a reality and
wasted many weeks working through the gauntlet of half truths.
It is totally a bogus lie that this can be done.

David,thanks for your answer.
My situation is the following:I have a table with various 1-n
relationships,and I need to show all of this in a single report,is there
some way to do this?

I’ve created a Java class(executed through my Jruby app) that
successfully generates the “parent” report,but I´m not figuring it out
how to show its “childrens”.

Regards,
Rafael R.

This really sounds like a JasperReports question and not really
anything with Rails. To do a parent/child report in JR you need to
have a sub-report for the children that the render process will
populate with your collection of children. If you’re using iReport to
build your report it’s pretty straight forward.

Rafael,
Sure. I use Ruport which is really cool and you’ll find many examples
of this if you Google.
I’d very much like to share information on JRuby if you’d contact me.

It is cumbersome to render a subreport from Rails.So I just wondered if
someone has already come up with another solution
