Thanks for the heads up. I have been deving with MG,ColdSpring,
and Reactor for about 1 1/2 years and like the ORM. Haven't really used
Transfer yet. I would like to know more behind the scenes for my own projects.
My 'productivity' is still either using an ORM or just working with DAOs and
Gateways directly. Service Objects are the next on my 'things to learn list'.

I believe there's a tradeoff here so far as learning OO goes.
Using a combination of MG, Transfer and Coldspring for instance will give you a
good example to learn from. Once you see how things are done using the
frameworks, you may be in a better position to architect something on your own.
Speaking from experience, it can take a very long time to put all the pieces
together on your own, years. And if you need to be productive in that time,
well, that's where I'd recommend that someone new to this jump into what seems
like the deep end and use these frameworks for awhile. That said, you need to
know at least the basics of using components to use the frameworks.
Attempting to build something without the frameworks may seem like a shallower
learning curve, but what you may find down the road, once you get your basic
business object, DAO and/or gateway working is that you don't know how to
progress from there. You'll be in deep water without knowing it. Your
applications take you longer to build, it seems like you've learned something,
but now what? If that's as far as we get, from a productivity standpoint, we
should just stay with procedural code.
The frameworks give us the space to be apprentices of OO, which is good, rather
than taking too large a step, attempting to be a master of OO in too short a
time, and usually, for most of us, without any personal guidance. They also
allow us to focus on our client's needs, rather than get lost in abstract
architectural questions. I find Transfer in particular allows me to be much
more productive than I would be using procedural code.
If I were to guide someone, I'd suggest that they dabble in attempting to build
a simple application on their own, just to get the hang of using CFC's in an
object oriented manner. But just dabble. Jump into using the frameworks as soon
as you can, even if it seems like the deep end. It will probably save you from
developing a code base that you need to rebuild from scratch several times
over! If you are staking your finances on such a code base, I think you'll be
much better off using the frameworks rather than on your own.

Ah, there's my cue. Transfer recommended!
Another option is Transfer (before someone recommends it :-) )

Subject: [CFCDEV] Help in learning service objects: How to use
I downloaded and installed Brian Rinaldi's Illudium PU-36 Code Generator. It
produced a DAO, a Gateway, a bean, and a service object. I am attempting to
learn how a service object works, or, more imporantly, how to use the service
object. It comes with the following functions. (mine happens to be
releasesServices.cfc)
init (takes an instance of the DAO and the Gateway)
createreleases
getreleases
getreleasess
savereleases
deletereleases
So basically, I am getting the DAO (create,get,save,delete) and a Gateway
(getreleasess)? How can I call the gateway to return a list of records. Or,
more important, how can I use the results on my view? Its returned as an array.
What am I missing. I need the education :-)
I can setting my controller to:
<cfset RDAO = createObject("component",
"medPortal.apps.newsroom.model.releases.releasesDAO").init("prmc-media_asql")>
<cfset RGW = createObject("component",
"medPortal.apps.newsroom.model.releases.releasesGateway").init("prmc-media_asql")>
<cfset RS = createObject("component",
"medPortal.apps.newsroom.model.releases.releasesService").init(#RDAO#, #RGW#)>
<cfset allReleases = RS.getreleasess()>
Here is the full function:
