I'm trying to understand groups, composition and membership relation. From the docs and forums I've gathered some vague understanding of the concepts. Am I right in that the basic difference between composition and membership is transitivity?
that if user X is a part of (i don't if i should use the word member) Group A and Group A has a composite relalation to Groub B then X has a composite relation to Group B also.
where as if user X is a part of Group A and Group A has a member relation to Group B then user X does not necessarily have a relation to Group B.
Is this right?
My practical purpose is that in my site I would like to create group heirarchies as such:
Company Internal Groups
Company Customers Groups
My implementation in OACS is thus:
Company Internal Groups - Group Type
--Managers Group - Group of group type Company Internal Group
----manageruser1 - User composite of Managers Group
--Employees Group - Group of group type Company Internal Group
----employeeuser1 - user composite of Employees Group
Company Customers Groups - Group Type
--Customers - Group of Group Type Company Customers Groups
----CustCompany1 - Group composite of Customers Group
-------CustCompany1user1 - User composite of CustCompany1
-------CustCompany1user2 - User composite of CustCompany1
----CustCompany2 - Group composite of Customers Group
-------CustCompany2user ... - User composite of CustCompany2
Am I totally off in my take on this? As you can see, I didn't use membership relation at all because they are straight up heirarchies. Is this correct? Also is that the proper use of group type?
Also is there an existing function that will give you a user's immediate group. Or can you define a primary group that the user is a member in? I need this for one of my fields. (In the above example, I need to note always that the userA from custcompanyA)
On a side: I've been looking for a list of basic functions liket ad_system_name and the like. Can't seem to find it in the api browser. Can anyone point me to the right place? In particular I'm looking to find some user and group specific functions.
Thanks a lot in advance. Making some progress but I really am not confident in my grasp of some of the concepts and am reluctant to move forward.
