Question

this my model app
import mongoose, { mongo, Schema } from "mongoose";
const app = mongoose.Schema({
'name':{
type: String
},
'parent':{
type: String
},
'order':{
type:Number
},
'path':{
type: String,
},
'accesses': [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Accesses"
}
]
},
{ timestamps: true },);
export default mongoose.model('Apps',app);
this my model accesses
import mongoose, { mongo } from "mongoose";
const accesses = mongoose.Schema({
'name':{
type: String,
require: true
},
'app':[{
type: mongoose.Schema.Types.ObjectId,
ref: "Apps"
}]
},
{ timestamps: true },);
export default mongoose.model('Accesses',accesses);
this my controller
export const saveApp = async (req,res) => {
try {
const app = new App(req.body);
const accesses = app.accesses;
let newAccs = [];
for (const acc of accesses)
{
const newAcc = await Accesses.findById(acc._id)
newAccs.push(newAcc);
}
app.accesses = newAccs;
const result = await app.save()
res.status(201).json(result);
} catch (error) {
res.status(400).json({message: error.message});
}
}
this my client.rest

"accesses": [
{
"app": [],
