yii \ rbac \ DbManager設置

Question

嘗試爲Yii2設置DbManager。關於php版本有很多線索，但是，對於數據庫版本並不多。

我所知道的：

第1步：遷移腳本

./yii migrate --migrationPath=@yii/rbac/migrations/ 

第2步：配置

... 
'authManager' => [ 
    'class' => 'yii\rbac\DbManager', 
    'defaultRoles' => ['admin', 'user', 'guest'], 
], 
... 

第3步：設置角色/規則

???? 

Answer 1

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

    // add "createPost" permission 
    $createPost = $auth->createPermission('createPost'); 
    $createPost->description = 'Create a post'; 
    $auth->add($createPost); 

    // add "updatePost" permission 
    $updatePost = $auth->createPermission('updatePost'); 
    $updatePost->description = 'Update post'; 
    $auth->add($updatePost); 

    // add "author" role and give this role the "createPost" permission 
    $author = $auth->createRole('author'); 
    $auth->add($author); 
    $auth->addChild($author, $createPost); 

    // add "admin" role and give this role the "updatePost" permission 
    // as well as the permissions of the "author" role 
    $admin = $auth->createRole('admin'); 
    $auth->add($admin); 
    $auth->addChild($admin, $updatePost); 
    $auth->addChild($admin, $author); 

    // Assign roles to users. 1 and 2 are IDs returned by IdentityInterface::getId() 
    // usually implemented in your User model. 
    $auth->assign($author, 2); 
    $auth->assign($admin, 1);
