我在项目中使用了jenssegers / laravel-mongodb库。我有一个集合,其中创建一个子文档与其他详细信息。现在我必须实现一个搜索查询来搜索集合的子文档。子文档是product_data,我想在其中搜索索引6。我想在其中搜索国家/地区名称。我怎么能这样做。收集的结构如下:

{
   "_id": ObjectId("564d32f191c1cb1f087d7c71"),
   "userid": "55c487a1083f11aa1b8b4567",
   "shopid": "anotherstore",
   "postedby": null,
   "purpose": "sell",
   "cat_ids": [
         "TDC00-001-001",
   ],
   "postdate": "2015-11-19",
   "desc": "T-SHIRT",
   "thumb": "http://test.local/uploads/product_img/prod-8yKsMHC2-1447895652.jpg",
   "product_data"▼: {
       "1": "2015-11-19",
       "2": "anotherstore",
       "3": "T-SHIRT",
       "4": "1245",
       "6": "Styling features include twin needle stitching for neatness and strength on the collar, sleeve and h",
       "5": "US",
       "6": "US"
   } 
}

我尝试过一些查询但没有成功。那些是:

 $country=Array(
    [0] => Australia
 )
 $country = Products::whereIn('product_data[6]', $country)->get();
 or
 $country = Products::where('books', 'elemMatch', array([6] => $country))->get();

如果有人知道请帮助。

1 个答案:

答案 0 :(得分:3)

因为子文档的查询在mongo中是这样的:

db.products.find({'product_data.6':'US'});

您只需在代码中重新创建该结构:

$country = 'US';
$queryFilter = ['product_data.6'=>$country];
Products::where($queryFilter)->first(); //or get whatever.

如果你想搜索一系列国家,你必须使用whereIn方法

$countries = ['US','SPAIN']; 
$results = Products::whereIn('product_data.6',$countries)->get();
