Question

所以，我创建了权限和角色，而不是注册每个用户获得＆＃34; user＆＃34;角色。当用户试图更新其他人的帖子时，他不能，这没关系。问题是他甚至无法更新他的帖子。无法弄清楚。（所有这些都适用于我更换＆＃34;用户＆＃34;与＆＃34; @＆＃34;在控制器中）

tasks:
id, task, prerequisite_id
1, A, 1
2, B, 2
3, C, 4

todos:
id, user_id, task_id, prerequisites
1, 1, 1, 7
2, 1, 2, 2
3, 2, 1, 5

AuthorAccessRule（在stackoverflow上找到它）：

public function up()
{
    $auth = Yii::$app->authManager;

    //creating post
    $createPost = $auth->createPermission('createPost');
    $createPost->description = 'Create Post';
    $auth->add($createPost);

    //deleting post
    $deletePost = $auth->createPermission('deletePost');
    $deletePost->description = 'Delete Post';
    $auth->add($deletePost);

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

    //delete user
    $deleteUser = $auth->createPermission('deleteUser');
    $deleteUser->description = 'Delete User';
    $auth->add($deleteUser);

    //create role 'user' and add permissions
    $user = $auth->createRole('user');
    $user->description = 'User';
    $auth->add($user);
    $auth->addChild($user, $createPost);
    $auth->addChild($user, $deletePost);
    $auth->addChild($user, $updatePost);

    //create role 'admin' and add permissions
    $admin = $auth->createRole('admin');
    $admin->description = 'Administrator';
    $auth->add($admin);
    $auth->addChild($admin, $user);
    $auth->addChild($admin, $deleteUser);
}

public function down()
{
    Yii::$app->authManager->removeAll();
}

和控制器：

class AuthorAccessRule extends AccessRule
{
    public $allow = true;
    public $roles = ['@'];

    public function allows($action, $user, $request)
    {
        $parentRules = parent::allows($action, $user, $request);
        // $parentRes can be `null`, `false` or `true`.
        // True means the parent rule matched and allows access.
        if($parentRules != true)
        {
            return $parentRules;
        }

        return ($this->getProjectAuthorId($request) == $user->id);
    }

    private function getProjectAuthorId($request)
    {
        // Fill in code to receive the right project.
        // assuming the project id is given à la `project/update?id=1
        $postId = $request->get('id');
        $post = Post::findOne($postId);
        return isset($post) ? $post->user_id : null;
    }
}

尝试调试parent :: allow未通过的条件。哟可以通过例如：

来做到这一点

public function allows($action, $user, $request)
{
    $a = $this->matchAction($action);
    $b = $this->matchRole($user);
    $c = $this->matchIP($request->getUserIP());
    $d = $this->matchVerb($request->getMethod());
    $e = $this->matchController($action->controller);
    $f = $this->matchCustom($action);
    $g = $this->allow;

    throw new \Exception("$a, $b, $c, $d, $e, $f, $g");

    $parentRules = parent::allows($action, $user, $request);
    // $parentRes can be `null`, `false` or `true`.
    // True means the parent rule matched and allows access.
    if($parentRules != true)
    {
        return $parentRules;
    }
    return ($this->getProjectAuthorId($request) == $user->id);
}
