Reports
Hi Folks (mainly Dan),
I'm posting this to the list rather than private email, but feel free to correct my "list etiquette", I'm conscious to balance openness/ wide circulation against keeping the list short and on-topic.
To improve my understanding of Isis and to establish new potential features, I'm adopting a "devil's advocate" approach by looking at features I add to my projects and asking "can (or should) Isis do this"
In this way I thought of _reports_, with filtering, sub/totals, and output to PDF/ CDR/ XLS.
The data to report on may be Domain Objects, or joins / query results (perhaps "ViewModels" ie similar to "Views" in database parlance.)
How would Isis approach this?
Best regards
Mike Burton

Cool, for the demo demonstration thing, It would be better if you
could record a video that you share and we can watch. I would say to
have a Skype call, but I am not sure about that ?
Wdyt guys. for me I would go for both, that is Mike upload a demo
video and we have a call for a private presentation about it, ideas ?

Hi Nour,
I could put together a demo of how I do it at present, to give ideas of whether and how Isis could do similar.
My current approach is to use Seam+RichFaces for the UI, and JasperReports for the report, using the paid-for Jasper Assistant to do the report design / layout. For XLS and CSV I create a second report layout that has no headings or totals etc.
I think JasperReports would be OK to use in Isis from a licensing pov? See http://fecplanner.com/jasperreports/docs/license.html
I'm currently working on an example that would make a good demo. I have finished the UI, I could attach a link to it if you like, or the image itself, what would be best (do we have a standard re attached images in emails?)
Best regards
Mike Burton

Hi Mike...
I think this would be great, do you have any code which you can show a demo ?

Looks like we're on the same page, interested to see what you come up with.

I called it "process object" pattern in my book, though that was really
only half the story since I was talking mostly about input of data for a
specific use case, eg a wizard. A name I had come up with for an object
designed for output was "report object".
But the term "view model" seems to be catching on, at least in the .NET
world, so I'd be happy to adopt it to instead of either of the above terms.

Many thanks Dan,
My Report class does similar to PdfRenderService & XlsGenerationService etc, I should probably spilt it into separate classes, with adapters for each platform (seam, jsf, servlet...) I could then see generation & customisation of layouts working in a similar way to Facelets Views, so will give it more thought.
Might there be a better name for it than "view model" btw?

Hi Mike,
Sorry not to reply sooner. Thought I'd pick this thread up from your
original question.

The way we've done this sort of thing on the big Irish project is to
either extract information out of the domain objects themselves, or to
create a "view model" that aggregates relevant information into a single
transient (never persisted) object. We then hand this raw information
off to an injected domain service, which does the actual work of
generating the PDF, XLS etc.
For example, for sending out letters we have a FormCommunication (this
is the view model). This references a Customer, some of the relevant
relationships of that Customer (eg spouse/child etc), Benefits and so
on. We then use the XmlSnapshot capability (see either my book or the
new applib documentation, chapter 12) to generate XML. From this we can
do whatever: apply XSLT, use Xpath to extract info, etc etc.
So... is there functionality missing from Isis? Well, only insofar
that'd it'd be nice to have a bunch of these domain services
(PdfRenderService, XlsGenerationService etc) available for reuse.
This'd be a nice project for someone to pick up. I was thinking that
eventually these precanned domain services might live under
trunk/domain/services (you'll notice a placeholder in the maven modules
page on the wiki [1]).
