I am saving data for farm in User ,but i have tried many things to save data to farm field.I have created an api that signup a user and data is saved ,farm is one of its object,I want to add farm after signup to that specific user .Recently i have tried to update and my code converts the farm into null.A user can have many farm.
I am using mongoose and express and passport for authentication .I have changed farm to Object,ObjectID,Array but none helps,everytime farm is converted to null.Is my schema correct ?
Schema
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
//Device Schema
const Device = new Schema({
modelNumber: {
type: String,
required: true
},
deviceType: {
type: String,
required: true
},
description:{
type:String,
required:false
},
deviceLocation:[
{
latitude:Number,
longitude:Number
}
],
AddedDate: {
type: Date,
default: Date.now
},
});
// User Schema
const UserSchema = new Schema({
name: {
type: String,
required: true
},
email: {
type: String,
required: true,
},
password: {
type: String,
required: true
},
location:{
type:String,
required:true
},
createdDate: {
type: Date,
default: Date.now
},
farm:[
{
_id:mongoose.Schema.Types.ObjectId,
description:String,
farmAddDate:{type:Date,default:Date.now},
device:[{Device}]
}
]
});
module.exports = User = mongoose.model("users", UserSchema);
Add Farm API
//@route POST api/user/addFarm
//@desc POST Register Farm
//@access Public
addFarm=function (req,res){
User.findOneAndUpdate({ farm: req.body.farm }).then(farm => {
if (farm) {
return res.status(400).json({ farm: "Farm already exists" });
} else {
const newFarm = Farm({
_id:req.body._id,
description:req.body.description,
device:req.body.device
});
newFarm
.save()
.then(farm => res.json(farm))
.catch(err => console.log(err));
}
});
}
router.post('/addFarm',addFarm);
Register New User
router.post("/register", (req, res) => {
// Form validation
const { errors, isValid } = validateRegisterInput(req.body);
// Check validation
if (!isValid) {
return res.status(400).json(errors);
}
User.findOne({ email: req.body.email }).then(user => {
if (user) {
return res.status(400).json({ email: "Email already exists" });
} else {
const newUser = new User({
name: req.body.name,
email: req.body.email,
password: req.body.password,
location:req.body.location,
});
// Hash password before saving in database
bcrypt.genSalt(10, (err, salt) => {
bcrypt.hash(newUser.password, salt, (err, hash) => {
if (err) throw err;
newUser.password = hash;
newUser
.save()
.then(user => res.json(user))
.catch(err => console.log(err));
});
});
}
});
});
