I have the following MongoDB model:
const Relation = mongoose.model('Relation',{
name :{
type: String,
},
port:{
type: Number,
},
services: { type : Array , "default" : [] }
});
Each port is a unique number for each document. A collection could have the following values:
{
"port":"116", //unique number
"name":"xzy",
services: [
{"id":'1', "trust":"good"},
{"id":'2', "trust":"bad"},
]
}
How can for example make the "trust" value "bad" for the object with the "id"= 1 ??
I assume I should first find the collection that matchs the port number "116" and then find the object inside the Services array that has the "id" of 1. How can I do that in mongoose?

You can use $
positional operator to update value inside an array
Relation.findOneAndUpdate(
{ "port": "116", "services.id": "1" },
{ "$set": { "services.$.trust": "bad" }}
)
