为什么可以'；在Yii2中使用GII创建积垢

我在sql中创建了具有函数“join”的视图表。但当我试图用gii生成视图表时，有人说“与Rangkuman关联的表必须有主键”，我用与Rangkuman关联的表生成了主键。但还是像这张照片

这是朗库曼模型

<?php

namespace app\models;

use Yii;

/**
 * This is the model class for table "rangkuman".
 *
 * @property string $Fakultas
 * @property string $Departemen
 * @property string $KodeMayor
 * @property string $NIM
 * @property integer $TahunMasuk
 * @property integer $JenisKelamin
 * @property integer $StatusAkademik
 * @property string $Usia
 */
class Rangkuman extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'rangkuman';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['Fakultas', 'Departemen', 'NIM', 'JenisKelamin'], 'required'],
            [['TahunMasuk', 'JenisKelamin', 'StatusAkademik', 'Usia'], 'integer'],
            [['Fakultas', 'Departemen'], 'string', 'max' => 5],
            [['KodeMayor'], 'string', 'max' => 10],
            [['NIM'], 'string', 'max' => 11],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'Fakultas' => Yii::t('app', 'Fakultas'),
            'Departemen' => Yii::t('app', 'Departemen'),
            'KodeMayor' => Yii::t('app', 'Kode Mayor'),
            'NIM' => Yii::t('app', 'Nim'),
            'TahunMasuk' => Yii::t('app', 'Tahun Masuk'),
            'JenisKelamin' => Yii::t('app', 'Jenis Kelamin'),
            'StatusAkademik' => Yii::t('app', 'Status Akademik'),
            'Usia' => Yii::t('app', 'Usia'),
        ];
    }
}

我该怎么办？谢谢

哪一列是主键？我已经找到答案了。我键入了公共静态函数primaryKey（）{return array（'NIM'）；}
