I'm using Node.js. I got this document:
{
users: [ '614e000c826b2308ec49508d', '614e0021826b2308ec49508e' ],
_id: 61d5fe6af420232658ffe131,
name: 'Standard',
__v: 0
}
Which I assigned to a variale groupToEdit
I'm trying to remove one of the elements in the users array with this line:
await groupToEdit.updateOne(
{ _id: '61d5fe6af420232658ffe131' },
{ $pull: { 'users': '614e000c826b2308ec49508d' } }
)
But nothing is removed. What am I doing wrong?
Use this style:
await yourCollection.updateOne({
_id: mongoose.Types.ObjectId('61d5fe6af420232658ffe131')}, {
$pull: { 'users': '614e000c826b2308ec49508d' }
});
Your problem is that mongoDB store _id as ObjectId and you are passing it as a string. Type of the id you pass is important.
