Question

请教大家一个问题，我的yii2在使用的时候总是报错。代码如下
模型

<?php

namespace app\models;

use Yii;
use yii\mongodb\ActiveRecord;
use yii\captcha\captcha;

/**
 * DSP用户模型
 */
class UsersMongo extends ActiveRecord
{
    public $verifyCode;

    /**
     * [getDb 设置链接的数据库]
     * @return [type] [description]
     */
    public static function getDb()
    {
        return Yii::$app->mongo_dsp;
    }


    /**
     * [collectionName 集合名称]
     * @return [type] [description]
     */
    public static function collectionName()
    {
        // return 'dsp_users';
        return 'demo_users';
    }

    /**
     * [scenarios 场景设置--不同业务逻辑下不同的验证条件]
     * @return [type] [description]
     */
    public function scenarios()
    {
        return [
            'DoLogin'      => ['email','password','verifyCode'],        //登录时
            'DoRegister' => ['real_name','email','company_name','phone','password','verifyCode'],    //注册时
        ];
    }


    /**
     * [rules 验证规则]
     * @return [type] [description]
     */
    public function rules()
    {
        $real_name_msg         = '用户名称应由2~20个字符组成';
        $company_name_msg     = '公司称名应由2~20个字符组成';
        $phone_msg            = '手机号码格式有误';
        $password_msg        = '密码长度应在6~16个字符之间';

        return [
            [['real_name','email','company_name','phone','password','verifyCode'],'required','message'=>'{attribute}不能为空','on'=>'DoLogin'],
            [['email','password','verifyCode'],'required','message'=>'{attribute}不能为空','on'=>'DoRegister'],
            //用户名
            ['real_name','string','length'=>[2,20],'tooShort'=>$real_name_msg,'tooLong'=>$real_name_msg],
            //邮箱
            ['email','email','message'=>'邮箱格式错误'],
            //公司名称
            ['company_name','string','length'=>[2,50],'tooShort'=>$company_name_msg,'tooLong'=>$company_name_msg],
            //手机号码
            ['phone','match','pattern'=>'/^1[3|4|5|8][0-9]\d{4,8}$/','message'=>$phone_msg],
            //密码
            ['password','string','length'=>[6,16],'tooShort'=>$password_msg,'tooLong'=>$password_msg],
            //确认密码
            ['password2', 'compare', 'compareAttribute' => 'password','message'=>'两次输入密码必须一致'],
            ['verifyCode','captcha','message'=>'验证码有误', 'captchaAction'=>'users/captcha']
        ];
    }

控制器

<?php
namespace app\controllers;

use Yii;
use yii\web\Controller;
use app\models\UsersMongo;
use app\models\TestMongo;
use yiii\AccessControl;
use yii\Session;

/**

    public $layout = 'login_layout';

    public function actions()
    {
        return [
            'captcha' => [
                'class'     => 'yii\captcha\CaptchaAction',
                'height'     => 50,
                'width'     => 100,
                'minLength' => 4,
                'maxLength' => 4,
            ],
        ];
    }


    public function actionTest()
    {
        $session = Yii::$app->session;
        return $this->renderpartial('test',['model'=>new UsersMongo]);
    }

    public function actionDoLogin()
    {
        session_start();
        $model = new UsersMongo;
        $model->setScenario('DoLogin');        //设置本次模型使用什么场景
        $data = Yii::$app->request->post();
        $session = Yii::$app->session;
        var_dump($_SESSION);
        if($model->load($data) && $model->validate()){
            echo json_encode($data);
        }else{
            $errors = $model->getErrors();
            var_dump($errors);
        }
    }

视图

<script type="text/javascript" src="<?php echo Yii::$app->request->baseUrl;?>/javascript/jquery.js"></script>

<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\widgets\Pjax;

<?= $form->field($model, 'email') ?>
<?= $form->field($model, 'password')->passwordInput() ?>
<?= $form->field($model,'verifyCode')->widget(yii\captcha\Captcha::className(),['captchaAction'=>'users/captcha','imageOptions'=>['alt'=>'点击换图','title'=>'点击换图', 'style'=>'cursor:pointer']]);?>


<div class="form-group">
