I had done something similar a while back.
I had a Users table,
a Security table representing various aspects of the application that
users COULD have access to,
and a join table (UserSecurity) representing what security a user had
access to.
Given that I'd create a new User (which you do through the display
group)
But I'd also have to create a new UserSecurity Object and fetch the
Security object from the database that I want to assign them access
to. In the GUI I did this with a WOCheckBox - a list of available
Security Levels was available to the user to select and then assign.
If you're doing this programatically, then you'll have to fetch the
appropriate security objects into the editing context.
Having all the appropriate objects it was simply a matter of calling
addObjectToBothSidesOfRealtionshipWithKey.
User newUser = new User();
Security sec = (Security)fetchTheAppropriateSecurityObject(); //this
can be done however you like
UserSecurity userSec = new UserSecurity();
userSec.addObjectToBothSidesOfRelationshipWithKey(newUser, "toUsers");
userSec.addObjectToBothSidesOfRealtionshipWithKey(sec, "toSecurity");
Also be sure you have "Propagates Primary" key turned on in your
EOModel for the appropriate relationships (User.toUserSecurity() and
security.ToUserSecurity())
Hope this helps.

My problem to day is I want to create a user in my database and give
them permissions to use a specific application.
My database has 4 tables to to this USERS, PERMISSIONS, APPLICATIONS
and the link table APPLICATIONUSERPERMISSIONS (holds each of the 3
tables id's).
I have manage to create a user using a WODisplayGroup and inserting a
new object. How do I get that User permission to use a specific
application.
I have not tried to flatten this relationship yet, and I know what
app,
and what permission I want to give them, I just don't know how to
create it.
Can someone help me??
My logic so far is this:
//create a new 'empty user' by inserting A new object into a
WODisplaygroup
//populate their data
//save the session
What do I do next??
