An implementation question

Rails
1

Hi
This is an implementation question. I have various reports to be
generated in my application like PDF reports, Excel reports etc So I
tried like a main class Application report and all the other report
types its sub classes For example
TicketExcelreport < ApplicationReport
MyPdfreport < ApplicationReport

Could anybody please point what the pros and cons doing this?

Thanks in advance
Sijo

As your reports only seem to be different views of the same data, I
would rather suggest creating #to_xls, #to_pdf and so on for Report
class, rather than subclassing it. If you think the logic invloved is
too big an instance method, maybe creating a generic PDF::Builder (or
whatever, that’s shamelessly copied from XML::Builder) would be a
better idea, that way you could reuse that “pdf building” or “xls
building” logic elsewehere.
