通过提供正文mongoose/mongodb中的文档来更新多个文档 [英] Update multiple documents by providing documents in body, mongoose/mongodb

问题描述

我需要通过在正文中提供几个文件来更新它们.我无法查询它们，必须提供它们.

I need to update several documents by providing them in the body. I can't query them, they must be provided.

示例:

 var persons = [
    {id: 1, name'Joe', active: false}, 
    {id:2, name:'Jane', active: false})
];

此数据在正文中提供，我想将active属性设置为false.

This data is provided in the body and I want to set the active property to false.

exports.setActivePropertyOnPersons = function(input,callback){
  for(var i = 0;i<input.body.length;i++){
    mongoose.model('person').findOne({id:input.body[i].id}, function(err, person){
      person.active = false;
      person.save();
    })
  }
  callback.send(200)
};

这段代码感觉不好.有没有更好的查询来做到这一点?我在文档中找不到任何内容.

This code feels no good. Is there any better query to do this? I don't find any in the docs.

推荐答案

尝试将更新命令与"

Try using the update command along with the "$in" operator:

var ids= [];
for (var i=0 i<input.body.length; ++i) {
    ids.push(input.body[i].id);
}

mongoose.model('person').update( {id : {"$in":ids}}, {active:false} , {multi: true} , function(err,docs) { ... });
