[farcry-dev] Inherited Containers and Rules - Content Targeting

[Chris Kent]

I have developed a method to bridge the gap between creating 
page-containers and site-containers and the rules that are defined 
within them.

Inspired by Michaels idea and my need define rules that apply across 
sections of a tree, I decided that my approach would be to allow a child 
node to inherit the containers and rules of its ancestors.

The best way that I could see to do this was to modify the core 
containers.cfm. I hope that either Daemon like this idea or someone can 
suggest a better solution that does not require a core modification. The 
added code is clearly commented, and all existing functionality of 
containers remains intact.

The basis of this mod is to create a container within a template using 
the following naming convention. #stobj.objectID#_test!!inherit. The key 
part is using "!!inherit" to allow for the special processing in 
container.cfm.

What container.cfm does is look for "!!inherit" at the end of the 
container name. If found it will apply the rules for that instance, i.e. 
using the objectID of the page being displayed. If no rules are in that 
container, then it will look through the node's ancestors for containers 
with the same name until it finds one with rules. These rules will then 
be applied.

Please see the attached container.cfm for details. Although I have done 
preliminary testing, further testing will be needed to ensure that this 
works in all situations.

I know that we should not tamper with core, but I hope that this idea 
proves useful and finds it way into core for all to use.

Chris.
