id: rbac-with-domains-api title: RBAC with Domains API

A more friendly API for RBAC with domains. This API is a subset of Management API. The RBAC users could use this API to simplify the code.

Reference

global variable e is Enforcer instance.

e, err := NewEnforcer("examples/rbac_with_domains_model.conf", "examples/rbac_with_domains_policy.csv")

const e = await newEnforcer('examples/rbac_with_domains_model.conf', 'examples/rbac_with_domains_policy.csv')

$e = new Enforcer('examples/rbac_with_domains_model.conf', 'examples/rbac_with_domains_policy.csv');

e = casbin.Enforcer("examples/rbac_with_domains_model.conf", "examples/rbac_with_domains_policy.csv")

var e = new Enforcer("examples/rbac_with_domains_model.conf", "examples/rbac_with_domains_policy.csv");

let mut e = Enforcer::new("examples/rbac_with_domains_model.conf", "examples/rbac_with_domains_policy.csv").await?;

Enforcer e = new Enforcer("examples/rbac_with_domains_model.conf", "examples/rbac_with_domains_policy.csv");

GetUsersForRoleInDomain()

GetUsersForRoleInDomain gets the users that has a role inside a domain.

For example:

res := e.GetUsersForRoleInDomain("admin", "domain1")

const res = e.getUsersForRoleInDomain("admin", "domain1")

res = e.get_users_for_role_in_domain("admin", "domain1")

GetRolesForUserInDomain()

GetRolesForUserInDomain gets the roles that a user has inside a domain.

For example:

res := e.GetRolesForUserInDomain("admin", "domain1")

const res = e.getRolesForUserInDomain("alice", "domain1")

res = e.get_roles_for_user_in_domain("alice", "domain1")

List<String> res = e.getRolesForUserInDomain("admin", "domain1");

GetPermissionsForUserInDomain()

GetPermissionsForUserInDomain gets permissions for a user or role inside a domain.

For example:

res := e.GetPermissionsForUserInDomain("alice", "domain1")

List<List<String>> res = e.getPermissionsForUserInDomain("alice", "domain1");

AddRoleForUserInDomain()

AddRoleForUserInDomain adds a role for a user inside a domain. Returns false if the user already has the role (aka not affected).

For example:

ok, err := e.AddRoleForUserInDomain("alice", "admin", "domain1")

ok = e.add_role_for_user_in_domain("alice", "admin", "domain1")

boolean ok = e.addRoleForUserInDomain("alice", "admin", "domain1");

DeleteRoleForUserInDomain()

DeleteRoleForUserInDomain deletes a role for a user inside a domain. Returns false if the user does not have the role (aka not affected).

For example:

ok, err := e.DeleteRoleForUserInDomain("alice", "admin", "domain1")

boolean ok = e.deleteRoleForUserInDomain("alice", "admin", "domain1");

DeleteRolesForUserInDomain()

DeleteRolesForUserInDomain deletes all roles for a user inside a domain. Returns false if the user does not have any roles (aka not affected).

For example:

ok, err := e.DeleteRolesForUserInDomain("alice", "domain1")

GetAllUsersByDomain()

GetAllUsersByDomain would get all users associated with the domain. Returns empty string array if has no domain defined in model.

For example:

res := e.GetAllUsersByDomain("domain1")

DeleteAllUsersByDomain()

DeleteAllUsersByDomain would delete all users associated with the domain. Returns false if has no domain defined in model.

For example:

ok, err := e.DeleteAllUsersByDomain("domain1")

DeleteDomains()

DeleteDomains would delete all associated users and roles. It would delete all domains if parameter is not provided.

For example:

ok, err := e.DeleteDomains("domain1", "domain2")

GetAllDomains()

GetAllDomains would get all domains.

For example:

res, _ := e.GetAllDomains()

:::note If you are handling a domain like name::domain, it may lead to unexpected behavior. In Casbin, :: is a reversed keyword, just like for, if in a programming language, we should never put :: in a domain. :::
