How to stop picking pears?

Question

Yii

RBAC.
There are two roles: appleCollector and pearCollector. One for the apple picker, the other for the pear picker.
Possible promotion and demotion, ie. an apple picker can become a pear picker and vice versa.
The important thing is that the picker of apples under no circumstances has the right to pick pears and vice versa.
Is it possible to configure RBAC in such a way that the appleCollector role automatically disables pearCollector and pearCollector disables appleCollector?
Or do you need methods to write addAppleRole() and addPearRole(), in which to give one role and remove another?

Answer 1

If the roles are not interrelated, then you need to remove one and add another, if necessary. What promotion/demotion are we talking about if an apple picker cannot become a pear picker and vice versa? It's just a change of activity/role.
