title: One to Many mapping in mongoose, How to receive and process?
body: <p>The problem I have is a One to many mapping with mongoose(Mongodb). The one is the Order(buyer data) and the many is the Items(price,quantity,etc).</p>
  
  <p>1) How I should create the Schema for the the Order and items, like should I put the items in an array in the order?</p>
  
  <p>2) Would all the data be in one post function?</p>
  
  <p>I herd you can use ObjectId to link the many to one but I am not sure how to.</p>
