用 TableDataGateway 操作 ManyToMany 的中间表

roles	users	users_has_roles
role_id	user_id	user_id
rolename	username	role_id
		is_allow

class Users extends FLEA_Db_TableDataGateway
{
    var $tableName = 'users';
    var $primaryKey = 'user_id';

    var $manyToMany = array(
        array(
            'tableClass' => 'Roles',
            'joinTableClass' => 'UsersHasRoles',
            'foreignKey' => 'user_id',
            'assocForeignKey' => 'role_id',
            'mappingName' => 'roles',
        ),
    );
}

class Roles extends FLEA_Db_TableDataGateway
{
    var $tableName = 'roles';
    var $primaryKey = 'role_id';
}

class UsersHasRoles extends FLEA_Db_TableDataGateway
{
    var $tableName = 'users_has_roles';
    var $primaryKey = 'user_id';
}

/**
* 先删除所有数据
*/
$tableUsersHasRoles =& FLEA::getSingleton('UsersHasRoles');
$tableUsersHasRoles->removeAll();

$tableUsers =& FLEA::getSingleton('Users');
$tableUsers->removeAll();

$tableRoles =& FLEA::getSingleton('Roles');
$tableRoles->removeAll();

/**
* 插入角色记录
*/
$rowset = array(
    array('rolename' => 'EDITOR'),
    array('rolename' => 'AUTHOR'),
    array('rolename' => 'ADMIN'),
);
$tableRoles->createRowset($rowset);

/**
* 将用户和角色关联起来
*/
$roles = $tableRoles->findAll();
require_once 'FLEA/Helper/Array.php';
$roles = array_to_hashmap($roles, 'rolename', 'role_id');

/**
* 插入用户记录，并和角色关联
*/
$row = array(
    'username' => 'dualface',
    'roles' => array(
        /**
         * 用 #JOIN# 来指定中间表的其他字段需要的数据
         */
        array('role_id' => $roles['EDITOR'], '#JOIN#' => array('is_allow' => true)),
        array('role_id' => $roles['AUTHOR'], '#JOIN#' => array('is_allow' => false)),
    ),
);

$userid = $tableUsers->create($row);

/**
* 查询刚刚创建的用户
*/
$user = $tableUsers->find($userid);
dump($user);
