I'm still
not sure I agree -- given that in the end, you'll either do:
<cfoutput>#OutputHelloWorld()#</cfoutput>
[in which
case, no problem returning the string instead of directly
outputting]
Or, you'll
do:
<cfscript>
outputHelloWorld();
</cfscript>
[in which
case, a quick writeOutput() should be fine]
To combine
them together you might do something like this in your Application.cfm (or on
the calling page):
<cfscript>
dataThing =
createObject("component","dataThing").init();
displayThing
= createObject("component","displayThing").init();
apiThing =
createObject("component","apiThing").init(dataThing,displayThing);
application.api = apiThing;
</cfscript>
The
developer can then use application.api (or whatever you call it) when they want
to do their work -- in this way you can expose a very simple set of methods for
them to use that utilizes the dataThing and the displayThing without the
end-developer needing to worry about the complexities of how the
interact.

Subject: RE: [CFCDev] Display CFC (aka CFC for display purposes)Your CFC will be easier to use if you have a method that does the cfoutput, too. You can still have a method that returns a string, but go ahead and create another method to do the cfoutput, too. Like in my example.<cfcomponent><cffunction name="OutputHelloWorld"><cfoutput>#helloWorld()#</cfoutput></cffunction><cffunction name="HelloWorld"> <!--- keeping the data separate from the display ---><cfreturn "Hello, World"></cffunction></cfcomponent>How do you wrap them together? That sounds neat.-----Original Message-----

Subject: RE: [CFCDev] Display CFC (aka CFC for display purposes)I would also just add that rather than actually outputting inside of a method, it would make your code much more flexible to just return a string that contains your HTML. In that way you can do things like concatenate strings inside of CFSCRIPT and output them together later. I haven't seen much reason why you wouldn't want to do it that way if you are going to generate HTML.I'll also second that if you are going to do this it's probably worth splitting up the "data" and the "display" CFCs (even if you then wrap them together in a single facade).-----Original Message-----

Subject: RE: [CFCDev] Display CFC (aka CFC for display purposes)Mind you I stressed that you shouldn't _forget_ the Flash issue. I'm more worried about the CFC beginner than most of us on this list. ;)I'm working on a CFC now that uses a few methods that output. It's primarily to allow for a 'default' rendering of the application.=======================================================================

Subject: RE: [CFCDev] Display CFC (aka CFC for display purposes)As long as the CFC methods are purely display then the Flash Remoting issue doesn't exist--they can still access the business logic/data cfc which presumably the display cfc is using.As long as the CFC is purely for display then I personally see no problem with using it.I haven't read much about it, but since MachII is all CFC based, does it use CFC's for display or still CFM's?Sam----------------------------------------------

Subject: RE: [CFCDev] Display CFC (aka CFC for display purposes)Actually, there was a very good argument against this pre-RedSky. If you cached the CFC you would lose the ability to output.Another reason to not output... and thiis just something to remember, not really an arguments against using output at all - but if you output instead of returning, Flash Remoting can't use the method. Again, it's not a big huge deal, but it's something you _should_ remember before using output.
