How to render a complex report?

Question

Ruby on Rails

Hello toaster, there is one report.
The report is complex, it makes selections from many models, then groups the data, etc. The question is, how will it be most convenient to transfer such data to the view? Put in rubihash or write a class? Do rails offer any standard solutions for such purposes?

Answer 1

I usually store all the data in the rubyhash in the controller / model, and then display it in the view.
Using a class might be overkill. Rails is not required to provide solutions for every occasion. That's what gems are for.
For complex reports, you can use helpers to automate building blocks.
Moreover, the final report can be presented in the end as pure data in XML (as a serialized rubihash), and then transformed into the desired representation using XSLT:
