NAME¶

CGI::Application::Plugin::Authorization::Driver::DBI - DBI Authorization driver

SYNOPSIS¶

 use base qw(CGI::Application);
 use CGI::Application::Plugin::Authorization;
 # Simple task based authentication
 __PACKAGE__->authz->config(
     DRIVER => [ 'DBI',
         TABLES      => ['account', 'task'],
         JOIN_ON     => 'account.id = task.accountid',
         USERNAME    => 'account.name',
         CONSTRAINTS => {
             'task.name' => '__PARAM_1__',
         }
     ],
 );
 if ($self->authz->authorize('editfoo') {
    # User is allowed access if it can 'editfoo'
 }

DESCRIPTION¶

This Authorization driver uses the DBI module to allow you to gather authorization information from any database for which there is a DBD module. You can either provide an active database handle, or provide the parameters necessary to connect to the database.

     TABLE => 'group',
 - or -
     TABLES => ['user U', 'group G'],

     JOIN_ON => 'user.id = group.userid',
 - or -
     JOIN_ON => 'U.id = G.userid',

     USERNAME => 'name'
 - or -
     USERNAME => 'U.name'

     CONSTRAINTS => {
         'user.active' => 't',
         'group.type'  => '__PARAM_1__',
         'group.name'  => '__PARAM_2__',
     }

     SQL => 'SELECT count(*)
               FROM account
               LEFT JOIN ip ON (account.id = ip.accountid)
               LEFT JOIN task ON (account.id = task.accountid)
              WHERE account.name = ?
                AND (ip.address >> inet ? OR task.name = ?)
            ',

EXAMPLE¶

 #
 # Example table structure (for PostgreSQL):
 #
 CREATE TABLE account (
   id         SERIAL NOT NULL PRIMARY KEY,
   name       VARCHAR(50) NOT NULL
 );
 CREATE TABLE task (
   id         SERIAL NOT NULL PRIMARY KEY,
   accountid  INTEGER NOT NULL REFERENCES account(id),
   name       VARCHAR(50) NOT NULL
 );
 CREATE TABLE ip (
   id         SERIAL NOT NULL PRIMARY KEY,
   accountid  INTEGER NOT NULL REFERENCES account(id),
   address    INET NOT NULL
 );
 INSERT INTO account (name) VALUES ('testuser');
 INSERT INTO task (accountid, name) VALUES (1, 'editfoo');
 INSERT INTO ip (accountid, address) VALUES (1, '192.168.1.0/24');
