You can, but it's better to pretend you can't.
There's a nasty little side effect of CFIN

ay you have only one argument to worry about and, since structures are
passed by reference, only one copy of the date to maintain.

Ok, I must be missing something here, but I specify my datasource in my
Application.cfm file (in the request scope, framework was written in CF5 days) and I
can reference it just fine in a cfc as #Request.Datasource#.

Mike,
It can be referenced fine from within the CFC, but it's probably not a
good idea. A CFC shouldn't "reach out" to external data, but instead
be told what it needs to know. Doing otherwise breaks what's known as
'encapsulation' in the OOP world. Basically, it lowers the
reusability of your
Joe that seems a good point. One that had slipped by me until now.
is there a shorthand way to pass the datasaource name to CFCs or do
you have to include the datasource name as one of the arguments every
time you instantiate a CFC?

There are certainly shortcuts, but for the sake of clean encapsulation I
would recommend that you simply pass it in as an ar

The method I use is to instantiate (in the application.cfm) a
"DP_PersistenceInfo" CFC - this CFC contains all of the properties related
to a specific datasource. This CFC is added to a special "DP_Application"
CFC which is, itself, stored in the Application scope.

Where applicable (on createObject/cfobject instead of cfinvoke), I make
an init() method that sets a local variable for a dsn. Init methods look
like:
function init(dsn) {
variables.dsn=arguments.dsn;
return this;
}
then to instantiate the cfc, it's like this:
myCFC = createObject("compo
Hey Mike,
I'm with Dave W. - it should probably be the argument to a method.
One thing a number of us have been doing (some people like it, some
people don't) is adding a method called "init" that takes
initialization parameters for a CFC and then returning the cfc itself.
It acts sort of like a

Joe,
This is pretty interesting, the init function and different ways of
calling CFCs...is there any further documentation on this anywhere?
I love seeing new ways to do things. This matches better what I have
used in other languages.
oh and PS, I tried your link in the footer

Josh,
You can find a few best practices/gudieliens here:
http://www.dintenfass.com/cfcbestpractices/. Nathan kindly put these
together based on threads/discussions on the CFCzone mailing list
(http://www.cfczone.org/).
Cheers

Egads, thanks Josh. I've corrected my sig :).
I'd suggest taking a look at mach-ii at http://www.mach-ii.com/ for a
very slick way of doing things in CF.

Thanks for the resources! I spent a good deal of time yesterday
looking at the docs and example apps at mach-ii.com
I'll let you all know how it goes.
