|« Using jAcl in modules||^ jAcl : rights management||Configuring jAcl.db »|
jAcl.db is the driver "db" for jAcl and use a database to store the rights. It implements the general concepts of jAcl, plus management of user groups. So the elements involved in the system in jAcl.db are:
- a subject
- a value
- a group of users
- an optional resource
Groups and users ¶
Each user belongs to one or more groups. A right is always attached to one or more groups and not to a specific user.
It is possible to assign rights to a single user, but there is a "private" group for each user, and rights for a specific user are attached to his private group (to facilitate treatment). And in a private group, there is only one user.
So there are three kind of groups:
- private groups. We don't see them in the list of groups
- normal groups
- default normal groups: those in which new users are automatically included.
Utility classes ¶
There are two classes for jAcl.db, to manage groups, users and rights: jAclDbManager and jAclDbUserGroup.
The use of these classes is similar to the commands in jelix-scripts to manage right (see next chapters..). So, just read API reference.
