Creating a distinctive property with the standard settings

How can we ensure a unique property is generated for a mongodb/mongoose model upon creation? What would be the most effective method to verify if the created value is not already in use and generate an alternative value before saving?

let schema = new Schema({
   name: {type: String},
   uniqueProperty: {type: String, unique:true, default:generateUniqueProp} // The current approach only works if the generated Value isn't already taken
})

Answer №1

What about considering a two-step approach?

  1. One option is to utilize an update operation with upsert, which essentially does nothing if the value already exists. This way, no new object will be created for existing values, but a new object will be added for non-existing values.
  2. If the object is successfully created, then proceed to add the remaining data. If not, you could retry with a different value.
