Hi all,
Just in time before the code freeze deadline, I committed an additional
sample for CForms [1], which shows how, using JDBI [2] and the
Collection wrappers for container widgets and repeaters [3] and a few
conventions, writing simple CRUD applications with Cocoon is a breeze. A
simple flowscript, a form definition and a few templates and you're done.
No Java classes, no binding file, no O/R mapping tool!
This sample is for now limited to editing one table, but I currently use
this approach on a small project with a few entities with associations
and compositions, and this works quite well. We'll have to expand this
sample to more than a simple table, but it's already a good start to
show people how to move away from the ugly inserts-with-sqltransfomer
pattern! And BTW I removed the previous sample that was using that
pattern...
This sample also uses some patterns (JS DAO objects) and conventions
(use of id for primary keys and xxx_id for foreign keys, generic
pipelines, etc) that we may want to factorize in some code generators or
run-time database introspection libaries. With Racoon, Crack and this
sample, Cocoon is back on the rails :-)
The live demo should be available soon at
http://cocoon.zones.apache.org/demos/trunk/samples/blocks/forms/sql/
Enjoy!
