yii2 with 的用法

1、在模型中先绑定

public function getCustomer()

{
    //子查询
    return $this->hasOne(CrmCustomer::className(), ['customer_id' => 'customer_id']); //关联表 => 当前模型主键
}

public function getBank()
{
    //子查询
    return $this->hasOne(CrmBank::className(), ['bank_id' => 'money_bank']); //关联表 => 当前模型主键
}

public function getPlatform()
{
    //子查询
    return $this->hasOne(CrmPlatform::className(), ['platform_id' => 'ad_platform_id']); //关联表 => 当前模型主键
}

public function getDepartment()
{
    //子查询
    return $this->hasOne(CrmDepartment::className(), ['department_id' => 'department_id']); //关联表 => 当前模型主键
}

public function getAdminuser()
{
    //子查询
    return $this->hasOne(AdminUser::className(), ['id' => 'admin_id']); //关联表 => 当前模型主键
}

public function getExt()
{
    //子查询
    return $this->hasOne(CrmKaihuExt::className(), ['kaihu_id' => 'id']); //关联表 => 当前模型主键
}

public function getAccount()
{
    //子查询
    return $this->hasMany(CrmAdAccount::className(), ['kaihu_id' => 'id']); //关联表 => 当前模型主键
}

2、这是一个kaihuMainSearch.php的search 模型查找数据，其实with可以用于任何地方，这里使用in查询，舍弃了leftjoin

<?php

use yii\base\Model;

    public $is_precharge;

    /**

            [['sub_industry','customer','operator','admin_notes','director_feedback','expiry_time','is_precharge'],'safe'],
        ];
    }

    /**

    public function scenarios()
    {
        // bypass scenarios() implementation in the parent class
        return Model::scenarios();
    }

3、介绍点with的高级用法 ，多表with叫搜索条件
var $condition = 0;
//评论数对比条件 
$user= user::find()->with(['ext','articles' => function 
($query) use($condition) { $query->where(['>','comment',$condition]); } 
])->all();
