Re: Relative path when instantiating a CFC?
Thanks for the enlightening interaction! My dev env is CF7 and prod is CF6.1. The template instantiating the CFC is in a folder at the same depth as the cfc, so I was hoping for ../ type relative paths. The directory structure looks something like this: /app_name/[version]/scripts/cf/ /app_name/[version]/scripts/cfc/ What I ended up doing is using a version variable and calling the cfc like this: app_name.#version#.scripts.cfc.component While my solution differed from the recommendations, they are definitely keepers and I will refer back to them.

Yes that's absolutely right - but my point is that you don't neccessarily have to refer to a component relative to the template from which you are calling it; it may be an option to refer to it from the app root. That could be a crucial piece of information for the OP. aarg -- Blog it up: http://fusion.dominicwatson.co.uk ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:298847 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Heh... okay, given... but I was addressing the question of relative to the template where the component is being instantiated, i.e. the default definition of "relative"... "relative" isn't "relative to the application root" unless you specifically include the qualifying phrase "to the application root". Though my understanding is that at least with previous versions of CF (not sure about CF8 given the addition of application-specific mappings) that it wasn't actually the application root, it was the web root and that those were actually still not independent of a cfserver mapping, because they relied on the "/" mapping created by the server when it's installed. And yet, I had one instance in which I had actually created a bunch of code that worked perfectly on my dev box by instantiating components from the web root (using that mapping) and had then copied that working code to a *nix server and it all suddenly failed. No explanation. The "/" mapping existed and was pointed correctly at the web root. All the pathing information was correct, it just didn't work. That's actually how I learned about the "/" mapping in the first place. Prior to that I hadn't realized that root-relative component discovery used a mapping, though it didn't help any. Ultimately was unable to use root-relative paths to load components on that server. So you and I had both been sort of "burned" by different aspects of that feature. -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 503.236.3691 http://onTap.riaforge.org/blog ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:298843 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Oh... speaking of which -- to the original poster -- if you're using CF8 you might want to look into the new features in Application.cfc that allow you to set per-application mappings.

My understanding is that it can only be done "one way" ... downward...
so if you've got
/com/blah/thing.cfc
/site/home.cfm
Then you wouldn't be able to use a relative path to instantiate
thing.cfc from within home.cfm -- however, you could if you had
/site/home.cfm
/site/com/blah/thing.cfc
then use CreateObject("component","com.blah.thing") within home.cfm --
the problem is that there's no way (as far as I know) to use "../" to
traverse the directory tree in reverse when instantiating a CFC because
it always interprets the dot as indicating a path separator, in spite of
the fact that I believe the server also allows you to use slashes to
mean the same thing in CFC paths.

Re: Relative path when instantiating a CFC?
> > I want to use a relative path when instantiating a CFC. Can this be done > when using createObject()? Can it be done at all? > It can't be done using relative notation. If the cfc is outside the root of your application, you can use a ColdFusion mapping. If it is within the root, a mapping is not required, i.e. theAppRootFolder --componentfolder mycfc.cfc --anotherFolder myTemplate.cfm anotherApplicationRoot --myOthercfc.cfc In myTemplate.cfm, you could use "compononentfolder.mycfc" to reference the mycfc.cfc component becuase ColdFusion checks cfc paths relative to the application root. If you wanted to instantiate the 'myOther.cfc' component however, you would need to create a mapping to the 'anotherApplicationRoot' folder then use 'myMapping.myOthercfc.cfc'. Mappings are created in the ColdFusion administrator, or if you don't have access you will need to put in a ticket with your host. You can also use something like ColdSpring to generate all your component instances. You still need to create mappings, but it really is a great thing so do check it out :) Dominic -- Blog it up: http://fusion.dominicwatson.co.uk ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:298797 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
