yii2-admin 插件使用简要教程 [ 2.0 版本 ]

按上面说的操作，结果点击角色页面报错：Call to a member function getRoles() on null，其他几个页面也是报错。

你好 使用yii2-admin安装成功后 点击菜单提示这个错误信息 Call to undefined method yii\helpers\Json::htmlEncode()' 这个是要怎样解决呢

我使用Yii2的基本应用程序模板安装完成yii2-admin后,查看路由只能看到admin下的路由列表
但是,路由列表中看不到app\controller下的控制器?请问为什么

module配置如下：

<?php
return  [ 
        'admin' => [
            'class' => 'mdm\admin\Module',
            'layout'=>'left-menu',
            'mainLayout' => '@app/views/layouts/main.php',
        ],
        
        'controllerMap' => [
            'assignment' => [
                'class' => 'mdm\admin\controllers\AssignmentController',
                /* 'userClassName' => 'app\models\User', */
                'idField' => 'user_id',
                'usernameField' => 'username',
                'fullnameField' => 'profile.full_name',
                'extraColumns' => [
                     [
                        'attribute' => 'full_name',
                        'label' => 'Full Name',
                        'value' => function($model, $key, $index, $column) {
                            return $model->profile->full_name;
                        },
                     ],
                     [
                     'attribute' => 'dept_name',
                     'label' => 'Department',
                         'value' => function($model, $key, $index, $column) {
                             return $model->profile->dept->name;
                            },
                     ],
                     [
                     'attribute' => 'post_name',
                         'label' => 'Post',
                             'value' => function($model, $key, $index, $column) {
                             return $model->profile->post->name;
                     },
                     ],
                 ],
                 'searchClass' => 'app\models\UserSearch'
                ],
         ], 
];

components配置如下

<?php
return 
    [
        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => 'Owod8SuyH0Syh2pjYY6LYGIGvKtQLHAt',
        ],
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
        'user' => [
            'identityClass' => 'app\models\User',
            'enableAutoLogin' => true,
        ],
    
        'urlManager'=>[
            'enablePrettyUrl' => true,
            'showScriptName' => false,//index.php
            ],
    
        'errorHandler' => [
            'errorAction' => 'site/error',
        ],
            'mailer' => [
                'class' => 'yii\swiftmailer\Mailer',
                // send all mails to a file by default. You have to set
                // 'useFileTransport' to false and configure a transport
            // for the mailer to send real emails.
            'useFileTransport' => true,
            ],
        'log' => [
                'traceLevel' => YII_DEBUG ? 3 : 0,
                'targets' => [
                    [
                        'class' => 'yii\log\FileTarget',
                        'levels' => ['error', 'warning'],
                ],
            ],
            ],
            'db' => require(__DIR__ . '/db.php'),
            //权限管理
            'authManager' => [
                'class' => 'yii\rbac\DbManager',
                'itemTable' => '{{%auth_item}}',
                'assignmentTable' => '{{%auth_assignment}}',
                'itemChildTable' => '{{%auth_item_child}}',
                "defaultRoles" => ["guest"],
        ],
        //样式管理
        'assetManager' => [
        'bundles' => [
            'dmstr\web\AdminLteAsset' => [
                'skin' => 'skin-blue',
            ],
            ],
        ],

我的安装好了，不过是英文的，怎么设置成中文呢：

执行第一句多错了 项目放到www yii 里面呢 ？

请问加上这条后GII就无法打开了吗？

'authManager' => [
    'class' => 'yii\rbac\DbManager', // 使用数据库管理配置文件
],

Yii2-admin只能对前台或者后台的权限进行管理，如何才能在后台实现对前后台的权限管理呢

我用的是basic版本的，没有frontend目录，那去哪配置yii2=admin的运行环境？

这样配置后没登录还是可以访问 admin 目录。难道这么配置不是未登录只能访问 site 目录吗?

能否对yii2-admin的页面进行修改呢

为什么我按照楼主的步骤安装好yii2-admin后，用户列表界面没有眼睛图案可以点击？而且我看了一下UserController，里面貌似也没有编辑页面，只有一个actionView，手动输入这个url后的界面和楼主截图的第四步图2完全不一样。

规则列表是干嘛的？怎么感觉你都没有用到它

这个插件需要框架版本2.0.7以上吗

'as access' 是什么，是哪个类的属性

请问在执行yii migrate --migrationPath=@yii/rbac/migrations的时候出现如上的状况是对的吗？谢谢！
