title: How to disallow "_id" in the request while creating resources using Python eve?
body: <p>I am using Python Eve to implement REST APIs.  </p>
  
  <p>While creating a resource with POST, It seems that I can pass a value for "_id" field in the request body and as long as the value fits Mongo's ObjectId format, Eve is using the passed in value as the ID of the resource.</p>
  
  <p>Is there any way to disable this behavior? Basically, I want IDs to be generated by the backend and don't want to allow clients to set them. I checked all the available configuration options and didn't find any in this regard.</p>
  
  <p>Thanks in advance,
  Raghu</p>
