I'm working on a multivendor cake selling project. the situation is the user can customize their cakes. to store that in mongo I can do simple post method and add it to mongo schema but the user info(id,name,phone,address) should be there too. how can I store the user info in the customize cake schema?

code I wrote is below.

exports.addCustomCake=(req,res)=>{
customCakeModel({
    user_id:req.saved_user._id,
    order_By:req.saved_user.name,
    phone:req.saved_user.phone,
    address:req.saved_user.address
    weight:req.body.weight,
    flavour:req.body.flavour,
    shape:req.body.shape,
    layers:req.body.layers,
    sponge:req.body.sponge,
    cakeType:req.body.cakeType,
    creamLevel:req.body.creamLevel,
    fondantLevel:req.body.fondantLevel,
    fondantCreamLevel:req.body.fondantCreamLevel,
    paintCake:req.body.paintCake,
    fillings:req.body.fillings,
    effects:req.body.effects,
    writingOnCake:req.body.writingOnCake,
}).save((err,customCake)=>{
    if(!err){
        res.status(200).json({
            status:'success',
            result:customCake,
            message:'Custom cake added...'
        });
    }else{
        res.status(404).json({
            result:err,
            message:'Custom cake add failed.'
        })
    }
})

}
