我目前在 laravel 5 中使用 jenseggers-mongodb eloquent 和 mongodb 3.0.3。我正在尝试加入两个不同的表,如下所示:
用户模型
public function userpayment() {
return $this->hasMany('App\Models\Userpayment', 'user_id', '_id');
}
用户付费模式
public function user() {
return $this->belongsTo('App\Models\User','user_id');
}
我正在使用存储库模式
public function __construct() {
$this->model = new User;
}
return $this->model->with(array('userpayment'=>function($query){
$query
->groupBy('dealCodeNumber')
->get();
}))
->where('_id',$sid)
->get();
groupBy dealCodeNumber
返回 NULL。
array:1 [▼
0 => array:15 [▼
"_id" => "55813f4cbc59a3f1372e9e6f"
"full_name" => "Varathan"
"username" => "shopsyadmin"
"web_url" => ""
"userpayment" => []
]
没有 groupby 会返回所有。
array:1 [▼
0 => array:15 [▼
"_id" => "55813f4cbc59a3f1372e9e6f"
"full_name" => "Varathan"
"username" => "shopsyadmin"
"userpayment" => array:2 [▼
0 => array:57 [▼
"_id" => "55816ce7cc7d4bac0d000029"
"dealCodeNumber" => "1398410837"
"inserttime" => "1398411401"
"status" => "Pending"
]
1 => array:57 [▶]
]
使用 groupby 查询日志
[query] => shopsy_user_payment.aggregate([{"$match":{"user_id":{"$in":["55813f4cbc59a3f1372e9e6f"]}}},{"$group":{"_id":{"dealCodeNumber":"$dealCodeNumber"}
为什么groupby返回null?
