Ruby / Rails Reporting Tools?

Question

I'm looking for a FOSS or paid framework that I can integrate into a rails application that will allow me to:

1. Create canned reports (data and graphs) and publish them to users.
2. Allow users to create their own custom ad-hoc reports based on data sets I give them. (i.e., I give them a data "view" and they can query it and slice and dice it how they want.

This needs to be something that I can install on a Heroku rails site.

Anyone have any ideas? Does such a thing exist? I know web based reporting solutions are often far from ideal, but I'm hoping there is a FOSS one on github somewhere that I can have the source code to and contribute to. I just haven't found any yet.

Thanks

i've seen two good gems on this topic. 1. Compendium 2. Repor

Answer 2

Although I'm not familiar with any of them, RubyToolbox has a reporting section for gems.
