How to automatically update a field in a collection?

Question

MongoDB

Strictly speaking, this is a trigger like RDMBS.
There is a collection of products with fields:

• _id (Object ID)
  
• quantity (number)
  
• enabled (Boolean)
  

When the products.quantity field is updated to the value = 0 , the products.enabled field was set to false automatically depending on the products.quantity and also products.enabled = true if products.quantity > 0.
Is this possible using the MongoDb database?

Answer 1

Perhaps this should be done at the application level?
