21 }

24 Role based access control is very simple: every user has a list of
25 roles, which that user is allowed to assume, and every restricted part
26 of the app makes an assertion about the necessary roles.
27
28 With "assert_user_roles", if the user is a member in all of the
29 required roles access is granted. Otherwise, access is denied. With
30 "assert_any_user_role" it is enough that the user is a member in one
31 role.
32
33 There are alternative approaches to do this on a per action basis, see
34 Catalyst::ActionRole::ACL.
35
36 For example, if you have a CRUD application, for every mutating action
37 you probably want to check that the user is allowed to edit. To do
38 this, create an editor role, and add that role to every user who is
39 allowed to edit.
40
41 sub edit : Local {
42 my ( $self, $c ) = @_;
43 $c->assert_user_roles( qw/editor/ );
44 $c->model("TheModel")->make_changes();
45 }
46
47 When this plugin checks the roles of a user it will first see if the
48 user supports the self check method.
49
50 When this is not supported the list of roles is extracted from the user
51 using the "roles" method.
52
53 When this is supported, the "check_roles" method will be used to
54 delegate the role check to the user class. Classes like the one
55 provided with iCatalyst::Authentication::Store::DBIx::Class optimize
56 the check this way.
57
59 assert_user_roles [ $user ], @roles
60 Checks that the user (as supplied by the first argument, or, if
61 omitted, "$c->user") has the specified roles.
62
63 If for any reason ("$c->user" is not defined, the user is missing a
64 role, etc) the check fails, an error is thrown.
65
66 You can either catch these errors with an eval, or clean them up in
67 your "end" action.
68
69 check_user_roles [ $user ], @roles
70 Takes the same args as "assert_user_roles", and performs the same
71 check, but instead of throwing errors returns a boolean value.
72
73 assert_any_user_role [ $user ], @roles
74 Checks that the user (as supplied by the first argument, or, if
75 omitted, "$c->user") has at least one of the specified roles.
76
77 Other than that, works like "assert_user_roles".
78
79 check_any_user_role [ $user ], @roles
80 Takes the same args as "assert_any_user_role", and performs the
81 same check, but instead of throwing errors returns a boolean value.
