I'm new to MongoDB, and I'm trying to do a very simple task, but however I can't get it right.
What I want is to change the process status but I tried "FindAndUpdate", "UpdateOne" and "FindByIdAndUpdate" but it won't work.
Maybe it has to do with my Schema. Should I create a new Schema for the Process?
My Database entry inside a MongoDB Collection:
_id: 622c98cfc872bcb2578b97a5
username:"foo"
__v:0
process:Array
0: Object
processname:"bar"
process_status:"stopped"
_id: 6230c1a401c66fc025d3cb88
My current Schema:
const User = new mongoose.Schema(
{
username: { type: String, required: true },
process: [
{
processname: {
type: String,
},
process_status: {
type: String,
},
},
],
},
{ collection: "user-data" }
);
My current code:
const startstopprocess = await User.findByIdAndUpdate(
{ _id: "6230c1a401c66fc025d3cb88" },
{ process_status: "started" }
).then(function (error, result) {
console.log(error);
console.log(result);
});
You can use positional operator $ in this way:
db.collection.update({
"process._id": "6230c1a401c66fc025d3cb88"
},
{
"$set": {
"process.$.process_status": "started"
}
})
Note how using positional operator you can say mongo "from the object you have found in find stage, update the process_status variable to started"
