Question

我有操作员和等级之间的关系表1
（操作者）
1.operator_id（PK）
2.operator_name
3.level_id（FK）

表2（水平）
1.level_id（PK）
2.level_name

运算符类的关系：

公共职能关系（）

{
        // NOTE: you may need to adjust the relation name and the related
        // class name for the relations automatically generated below.
        return array(
        'op_level'=>array(self::BELONGS_TO, 'Level', 'level_id'),
        );
    }

一些_view.php源代码：

<?php echo CHtml::encode($data->getAttributeLabel('level_id')); ?> 
                       <?php $op_level = Level::model()->findByPK($data->level_id);?>
    <?php echo $op_level->level_name;?>

它继续说'试图获得非对象的属性' 为什么它不能顺利运行??，我已经在其他项目上试过关系和这个方法，并且运行顺利，请帮我解决这个问题

这是操作员控制器：

Answer 1

获取相关的表格数据，

更改控制器中的代码如下：

public function actionIndex()
    {
        $dataProvider=new CActiveDataProvider('Operator',

            array('criteria'=>array(
                             'with'=>array(
                                           'op_level'
                                          ),
                             'together'=>true,
                            )   
                 )     
         );
        $this->render('index',array(
            'dataProvider'=>$dataProvider,
        ));
    }

在视图中

 <?php echo $data->op_level->level_name;?>

Answer 2

我可能刚刚找到解决方案，字段类型不仅仅是整数，但它默认设置为mysql：0000000由zerofill引起，我不是很确定，但我没有检查zerfofill operator_id字段，然后用gii重新创建模型，瞧...
