Update multiple documents by providing documents i

Question

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

Example:

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

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

Answer 1

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) { ... });

Hope this helps
