I am trying to write a tutorial for developing a webobjects
application in WOLips. The idea would be to add the separate chapters
as PDF's and Projects to the WODOC website, next to Pascal's podcasts.
The tool would be WOLiips and WebObjects 54x, plus assorted Frameworks
(Wonder, LEWOStuff, whatever is needed). The audience would be the
developer that knows it's way around in sql/ a computer language and
some object oriented concepts, and has developed some web stuff in php/
perl/asp or whatever. It is not intended to be a complete overview of
everything possible in webobjects, but it would give a feeling how to
set up a project, do a frontend/backend and give people a feeling of
the tools and how to extend them themselves.
The application would be a shop, with a D2W backend for the products
(with ERAttachment for the product-pictures), fulfilment (some kind of
app that could run in an ipod touch) and some statistics app that
would make use of displaygroups and SVG. The frontend would make use
of EROpenID, WOgooglecheckout and WOPaypalcheckout, some PDF
invoiceing and product-barcodes from LEWOstuff. And I want everything
to work. Not 12 code examples that do not work together. More or less
the MS-Access Northwind example (does that still exist?) or the
Filemaker Templates.
At least that is the idea for now.
I started with a data model with ERPrototypes and using subclassed
objects, which link to mysql/postgresql/frontbase/openbase.
That tutorial is nearly finished, so I am starting with the
DirectToWeb part. On Leopard, the DirectToWeb Assistant does not work.
Is there something I am missing that is available on Leopard/WO54 that
could make DirectToWeb the nice and easy way to quickly set up an
interface to a database?
(and no, Rule Editor is not an easy and quick tool if you're a
beginner and you don't want to shoot yourself in the foot)
Another question is how I could incorporate the picture ERAttachment
upload in the D2W interface. Does anybody already have an example or
short explanation?
PS: if you're interested in helping me out in proofreading or in
developing one of sub-projects (backend/shop/fulfillment/ statistics)
please let me know. I am sure I know a lot not.
