Yii2 RBAC Flere tildelinger for hver bruger baseret på grupper

Her er en fungerende endelig løsning.

Så en anden dag, mere refactoring.

Min endelige løsning bruger checkAccess-funktionen i DbManager/ManagerInterface-kildefilerne, men jeg tilføjede parameteren $assignments, der skulle videregives. Hovedproblemet er, at jeg var nødt til at bygge min egen opgaveliste til kontrol. Sørg for at kommentere linjerne, hvor $assignments-variablen er sat.

Her er min nye adgangsmodel:

<?php

namespace app\models;

use Yii;

class Access
{

public function canUser($type, $permissionName, $params = [])
{

    $auth = Yii::$app->authManager;

    switch ($type) {

        case 'group':

        $userID = Yii::$app->user->identity->id;
        $groupID = Yii::$app->options->getOption('user', 'active_group_id');

        $queryAll = GroupAccess::find()
        ->where('user_id = :user_id and group_id = :group_id', [':user_id' => $userID, ':group_id' => $groupID])
        ->asArray()
        ->all();

        $assignments = [];
        foreach ($queryAll as $queryItem) {
            $assignments[$queryItem['item_name']] = [
            'userId' => $queryItem['user_id'],
            'roleName' => $queryItem['item_name'],
            'createdAt' => $queryItem['created_date'],
            ];
        }

        $result = $auth->checkAccess($userID, $permissionName, $assignments, $params);

        return $result;

        break;

        case 'user':

        $userID = Yii::$app->user->identity->id;

        $queryAll = UserAccess::find()
        ->where('user_id = :user_id', [':user_id' => $userID])
        ->asArray()
        ->all();

        $assignments = [];
        foreach ($queryAll as $queryItem) {
            $assignments[$queryItem['item_name']] = [
            'userId' => $queryItem['user_id'],
            'roleName' => $queryItem['item_name'],
            'createdAt' => $queryItem['created_date'],
            ];
        }

        $result = $auth->checkAccess($userID, $permissionName, $assignments, $params);

        return $result;

        break;

    }

}

public function assign($type, $role, $userID = null, $groupID = null)
{

    switch ($type) {

        case 'group':

        // clear existing assigments
        self::revoke('group', $userID, $groupID);

        $groupAccess = new GroupAccess();
        $groupAccess->group_id = $groupID;
        $groupAccess->user_id = $userID;
        $groupAccess->item_name = $role;
        $groupAccess->created_date = time();

        return $groupAccess->save();

        break;

        case 'user':

        // clear existing assignments
        self::revoke('user', $userID);

        $userAccess = new UserAccess();
        $userAccess->user_id = $userID;
        $userAccess->item_name = $role;
        $userAccess->created_date = time();

        return $userAccess->save();

        break;

    }

}

public function revoke($type, $userID, $groupID = null)
{

    switch ($type) {

        case 'group':

        GroupAccess::deleteAll('user_id = :user_id and group_id = :group_id', [':user_id' => $userID, ':group_id' => $groupID]);

        break;

        case 'user':

        UserAccess::deleteAll('user_id = :user_id', [':user_id' => $userID]);

        break;

    }

}

}

Og her er den ændrede checkAccess-funktion i DbManager:

public function checkAccess($userId, $permissionName, $assignments, $params = [])
{
    //$assignments = $this->getAssignments($userId);
    $this->loadFromCache();
    if ($this->items !== null) {
        return $this->checkAccessFromCache($userId, $permissionName, $params, $assignments);
    } else {
        return $this->checkAccessRecursive($userId, $permissionName, $params, $assignments);
    }
}

Og her er den ændrede checkAccess-funktion i ManagerInterface.php:

public function checkAccess($userId, $permissionName, $assignments, $params = []);

Jeg ændrede ikke funktionerne $items, checkAccessFromCache og checkAccessRecursive til public from protected.

Og her er min UserAccess-model:

<?php

namespace app\models;

use Yii;
use yii\db\ActiveRecord;

 /**
 * This is the model class for table "app_user_access".
 *
 * @property integer $id
 * @property integer $user_id
 * @property string $item_name
 * @property integer $created_date
 *
 * @property AppAuthItem $itemName
 * @property AppUsers $user
 */
class UserAccess extends ActiveRecord
{
/**
 * @inheritdoc
 */
public static function tableName()
{
    return 'app_user_access';
}

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['user_id', 'item_name', 'created_date'], 'required'],
        [['user_id', 'created_date'], 'integer'],
        [['item_name'], 'string', 'max' => 64]
    ];
}

/**
 * @inheritdoc
 */
public function attributeLabels()
{
    return [
        'id' => 'ID',
        'user_id' => 'User ID',
        'item_name' => 'Item Name',
        'created_date' => 'Created Date',
    ];
}

/**
 * @return \yii\db\ActiveQuery
 */
public function getItemName()
{
    return $this->hasOne(AppAuthItem::className(), ['name' => 'item_name']);
}

/**
 * @return \yii\db\ActiveQuery
 */
public function getUser()
{
    return $this->hasOne(AppUsers::className(), ['id' => 'user_id']);
}
}

Og her er GroupAccess-modellen:

<?php

namespace app\models;

use Yii;
use yii\db\ActiveRecord;

 /**
 * This is the model class for table "app_group_access".
 *
 * @property integer $id
 * @property integer $group_id
 * @property integer $user_id
 * @property string $item_name
 * @property integer $created_date
 *
 * @property AppUsers $user
 * @property AppAuthItem $itemName
 * @property AppGroups $group
 */
class GroupAccess extends ActiveRecord
{
/**
 * @inheritdoc
 */
public static function tableName()
{
    return 'app_group_access';
}

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['group_id', 'user_id', 'item_name', 'created_date'], 'required'],
        [['group_id', 'user_id', 'created_date'], 'integer'],
        [['item_name'], 'string', 'max' => 64]
    ];
}

/**
 * @inheritdoc
 */
public function attributeLabels()
{
    return [
        'id' => 'ID',
        'group_id' => 'Group ID',
        'user_id' => 'User ID',
        'item_name' => 'Item Name',
        'created_date' => 'Created Date',
    ];
}

/**
 * @return \yii\db\ActiveQuery
 */
public function getUser()
{
    return $this->hasOne(AppUsers::className(), ['id' => 'user_id']);
}

/**
 * @return \yii\db\ActiveQuery
 */
public function getItemName()
{
    return $this->hasOne(AppAuthItem::className(), ['name' => 'item_name']);
}

/**
 * @return \yii\db\ActiveQuery
 */
public function getGroup()
{
    return $this->hasOne(AppGroups::className(), ['id' => 'group_id']);
}
}

Og endnu en gang nogle nyttige eksempler:

// assign group role
Yii::$app->access->assign('group', 'group_creator', 24, 20);
// assign user role
Yii::$app->access->assign('user', 'app_user', 24);

// revoke group
Yii::$app->access->revoke('group', 22, 18);
// revoke user
Yii::$app->access->revoke('user', 22);

// test user permission
var_dump(Yii::$app->access->canUser('user', 'manage_app_settings'));
// test the group permission
var_dump(Yii::$app->access->canUser('group', 'manage_group_settings'));
