Need to have a user in more than one groups in cakePHP

Hello I am trying the ACL component in cakephp for my web application. The example on their website for using their ACL structure has a many to one relationship between groups and users. A user can belong to one group, while a group can have more than one users in it.

But I have a situation where I need to have a few users in more than one group. For that I had to change the table structure, as it would be a many to many. So I built an associative entity called "groups_users". Now I have baked all the controllers, models, and views.

I have added groups and users, and things are working fine. I have also added the components into the parent class, AppController. I have also generated the ACL tables ACOs, AROs and AROs_ACOs using the baking console.

So in the groups_users add view, I have a list of users and groups. I can choose the users and their groups, and on submit a record has to be technically created in my groups_users table.

But to my surprise, records are being inserted into aros_acos table which is weird. I believe there is some internal relation between users, groups and the acl tables. I tried to understand if there was any foreign key cascading between these tables, but nothing was mentioned in the config/schema/dbacl.sql file.

I am pasting my table structure for a better understanding of my problem.

Do you mean when you insert a record assigning a user to a group?

Does your application work as expected apart from the problem you describe?

It's difficult to be sure from your description, but it's possible that an aro_aco record has to be created for each user/group combination.
