如何修复Yii2高级模板中的““ frontend \ models \ model”必须具有主键“错误

时间：2019-04-30 22:01:16

标签： php yii2

我正在尝试创建一个模型，显然所有过程都是正确的，但是当我试图在视图中显示他的错误时（立即在创建模型之后），Yii2-app抛出

  

无效的配置-yii \ base \ InvalidConfigException-“ frontend \ models \ mystore \ Staff”必须具有主键。

（直到现在）解决此问题的唯一方法是从本地服务器重新启动MySQL服务并刷新浏览器上的页面，此后我的应用程序将显示所有数据而没有错误，直到创建新记录为止。

我正在使用XAMPP（例如本地服务器）和MySQL（例如数据库管理系统），当我使用phpmyadmin搜索新记录时，一切正常，创建了PK，并且正确存储了所有数据。

创建Staff模型后，我希望浏览器重定向到索引页面，并且所有信息都可以显示在gridview中，但是我遇到了上面提到的错误。

下一步是完整的错误消息：

"Invalid Configuration – yii\base\InvalidConfigException
Primary key of 'frontend\models\mystore\Staff' can not be empty."

in C:\xampp\htdocs\myapp\vendor\yiisoft\yii2\db\ActiveQuery.php
  }
                $key = serialize($key);
                if (isset($hash[$key])) {
                    unset($models[$i]);
                } else {
                    $hash[$key] = true;
                }
            }
        } elseif (empty($pks)) {
            throw new InvalidConfigException("Primary key of '{$class}' can not be empty.");
        } else {
            // single column primary key
            $pk = reset($pks);
            foreach ($models as $i => $model) {
                if (!isset($model[$pk])) {
                    // do not continue if the primary key is not part of the result set
                    break;

似乎您的模型中没有主键（可能在表中）

您可以通过这种方式将主键字段手动添加到模型中
作为公共静态方法

  class Staff extends \yii\db\ActiveRecord
  {

      /**
       * {@inheritdoc}
       */
      public static function tableName()
      {
          return 'staff';
      }

     /**
       * @inheritdoc$primaryKey
       */
      public static function primaryKey()
      {
          return ["your_id_column"];
      }
