I am planning the architecture of a personal project to be implemented using Rails. In it, I would like it to be possible to easily modify user access rules, as is done in wordpress. I know there is the cancan to do this, but I believe it would not serve my need. It is a service-oriented application. Each user will only be allowed access to certain services. I thought of implementing a solution specific to that need that would allow the application administrator to easily modify users' access permissions through an administrative interface. Could someone tell me a solution to this?
