如何使用 Mongoose 从阵列中删除 object

Question

I have tried a lot of things but can't seem to get any of them to work as intended. Let's say I had something like the following.

{
      _id: '12345',
      name: 'John Smith',
      job: [
        {
             title: 'Web Developer',
             years: '12',
             status: 'not active',
         },
         {
             title: 'supervisor',
             years: '15',
             status: 'terminated',
         },
         {
             title: 'lead developer',
             years: '3',
             status: 'not active',
         },
         {
             title: 'Software Engineer',
             years: '9',
             status: 'active',
         },
      ]
 }

How can I remove the object with the status of 'terminated'? Also, would it be the same to remove all objects with that status of 'not active'?

Thanks.

Answer 1

You can use findOneAndUpdate with the $pull command.

Example:

User.findOneAndUpdate({/* filter */}, { $pull: {array: {/* condition */}} });

• $pull

Answer 2

Wondering if the below would work as well....

Model.findOneAndUpdate({'job.status' : "terminated"}, { $pull: job.$ }, {$multi : true});

Answer 3

Remove nested document using the $pull operator

var query = {
    _id: "12345"
};

var update = {
    $pull: {
        job: {
            status: {
                $in: ['terminated', 'not active']
            }
        }
    }
};

db.collection.update(query, update);
