Hm,
if you look at JasperReports it is Java. Can you implement this
internally into QGIS? Looking at reports in general some kind of
programming will always be needed to generate an individual report
because the data structure is individual, too, so I think it will always
be something for specialists.
An idea to start with would be to create a new element in Composer that
makes simple calculations like sum or average on a field: Choose layer -
choose field - choose what to do. Evaluation time will be the same as
for the map (either permanetly or on request but at least before printing).

(because it is not a main GIS feature). I successfully coupled a Python
implementation of JasperReports [1] with QGIS. JasperReports not only allows
sum/average and the like but also subreports (for ?:n relations) charts and much
more. AFAIK (but have not tried myself) LibreOffice output is possible, too.
This
solution needs some Python programming to create an XML document from your data
and
send the data and the report template to the server.
Hi all.
I agree this is an important issue. I heard there was some plan to implement
this:
anyone knows the current status, and the prospects for the future?
Obviously, we have always the same duality: implementing outside QGIS is easier
and
more powerful, reusing existing tools, whereas an internal implementation is far
smoother from an user point of view.
Historically, in most analogous cases we ended up implementing an internal
solution
(sometimes using common libs), and I suspect sooner or later we'll have to do
the
same for reporting also.
All the best.
