使用Golang在MongoDB中无循环更新文档

问题描述：

I have a collector module that pulls a remote API every 30 seconds. That gives me a list of objects that I insert or update in a MongoDB database.

{
   "id" : "oulkhhvoiupokb",
   "name" : "test1",
   "status" : "OPEN"
},
{
   "id" : "oulkhhvoisksbsjkkb",
   "name" : "test2",
   "status" : "CLOSED"
}

In fact, I only collect the objects that have the OPEN status. And with a loop, I set the rest of the object as CLOSED (because they are not OPEN). But in the future, it will take a lot of time because the amont of object will grow.

I work with Golang and MGO package.

Is there a way to do it faster and cleaner please ? Something like setting a basic field value for Mongo documents ?

To explain it differently, when I will insert the OPEN objects in the database, all the other ones that are already in database must be CLOSED. Can Mongo do it ?

Thanks.

我有一个收集器模块，该模块每30秒提取一次远程API。这会给我一个对象列表在MongoDB数据库中插入或更新。 p>

  {
“ id”：“ oulkhhvoiupokb”，
“ name”：“ test1”，
“ status”：“  OPEN“ 
}，
 {
” id“：” oulkhhvoisksbsjkkb“，
” name“：” test2“，
” status“：” CLOSED“ 
}

 实际上，我只收集具有OPEN状态的对象。 并通过循环将对象的其余部分设置为CLOSED（因为它们未打开）。
但是将来，这会花费很多时间，因为对象的数量会不断增长。 p>

我使用Golang和MGO软件包。 p> 
 
 
请问有没有一种方法可以使它更快更干净？ 像为Mongo文档设置基本字段值之类的东西？ p> 
 
 
要另外解释一下，当我将OPEN对象插入数据库时，必须关闭数据库中已经存在的所有其他对象 。  Mongo可以做到吗？ p> 
 
 
谢谢。 p>

答

Solution was to use func (c *Collection) UpdateAll(selector interface{}, update interface{}) (info *ChangeInfo, err error) with the $nin for the selector and $set for the update.
