php – Laravel Jensenggers Eloquent模型排序主模型与关系模型
作者:互联网
我试图通过关系模型列对主模型的整个数据集进行排序.我正在使用Laravel ORM 5.2.43和Jensenggers MongoDb 3.1
这是我的模特
UserEventActivity.php – Mongo模型
use Jenssegers\Mongodb\Eloquent\Model as Eloquent;
class UserEventActivity extends Eloquent
{
protected $collection = 'user_event_activity';
protected $connection = 'mongodb';
public function handset() {
return $this->hasOne('HandsetDetails', '_id', 'handset_id');
}
public function storeDetail() {
return $this->hasOne('StoreDetails', 'st_id', 'store_id');
}
}
HandsetDetails.php – Mongo模型
use Jenssegers\Mongodb\Eloquent\Model as Eloquent;
class HandsetDetails extends Eloquent
{
var $collection = 'user_handset_details';
var $connection = 'mongodb';
}
StoreDetails.php – MySql模型
use Jenssegers\Mongodb\Eloquent\HybridRelations;
use Illuminate\Database\Eloquent\Model as Eloquent;
class StoreDetails extends Eloquent
{
use HybridRelations;
protected $connection = 'mysql';
protected $table = 'icn_store';
}
PHP脚本
$activity = UserEventActivity::join('handset ', 'handset._id', '=', 'handset_id')
->join('storeDetail', 'store_id', '=', 'storeDetail.st_id')
->orderBy('handset.handset_make', 'desc')
->select('storeDetail.*', 'handset.*')
->get()
->toArray();
来自UserEventActivity的这些数据不是基于手机关系中的handheld_make字段存储的.
请帮我实现预期的结果
解决方法:
据我所知,MongoDB不支持这样的连接.
解决它的方法可能是使用急切加载.
所以你的UserEventActivity模型可能如下所示:
use Jenssegers\Mongodb\Eloquent\Model as Eloquent;
class UserEventActivity extends Eloquent
{
protected $collection = 'user_event_activity';
protected $connection = 'mongodb';
public function handset() {
return $this->hasOne('HandsetDetails', '_id', 'handset_id');
}
public function storeDetail() {
return $this->hasOne('StoreDetails', 'st_id', 'store_id');
}
public function getHandsetMakeAttribute()
{
return $this->handset->handset_make;
}
}
注意getHandsetMakeAttribute()访问器.
然后你可以用这个打电话:
$activity = UserEventActivity::with('storeDetail')
->with('handset')
->get()
->sortByDesc('handset_make')
->toArray();
根本没有测试,但值得一试.
