我有一个用户的文档结构为:我们如何移除mongodb中的子数组中的项目?
{
"_id" : ObjectId("5173b10fd0aa9af00d06395c"),
"customer_id" : 1,
"customer_fullname" : "Douglas E. Kelly",
"customer_email" : "[email protected]",
"customer_cityid" : "1",
"customer_selections" : [15, 952, 17347, 343102, 20380, 51757, 235961, 119824, 134011, 168251, 297596, 175792, 196010, 210349, 226945, 250102, 274064, 328834, 354893, 472868, 555878]
}
所以我想删号/“客户选择”的项目。我们应该怎么做?
UPDATE: 我正在使用此查询。但它不会删除数字
$response=$collection->update(array('customer_id' =>1), array('$pull' => array('customer_selections'=>$selectedcompanyid)));
var_dump($ response);
array(5) { ["updatedExisting"]=> bool(true) ["n"]=> int(1) ["connectionId"]=> int(3) ["err"]=> NULL ["ok"]=> float(1) }
