Updating single fields in an entry using express router

Hello all. Creating my first app with MERN, I'm trying to establish endpoints for CRUD ops. The tutorial I was following used express router for get and post requests to a mongodb, but the tutorial was sending every field an entry needs for a collection.I am just wanting to update a single field in an entry instead of having to send all the extra information again.right now I have a route that I only want to toggle an active or deactive flag for the userRoutes.route('/user/:id/deactivate').put(function(req, res) { USER.findById(req.params.id, function(err, user) { if(!user) { res.status(404).send("data is not found"); } else { user.user_active = req.body.user_active; user.save().then(user => { res.json('User updated successfully!'); }) .catch(err => { res.status(400).send("Update not possible"); }); } }); }); the model for the user is{ "user_name": "T. Elliot Sanders", "user_address": "100 west rd", "user_phone": "123456789", "user_cart": { "items": [], "total": 0, "formattedTotal": "0" }, "user_active": true } but when I run the route using postman to only update the user_active flag to false the entry in the collection has everything deleted except the user_active field. so after the route the entry is{ "user_active": false } So how do I update the single field, but not delete the others, but also not have to resend information that has not changed?
