Is there a way to find out if a record "is new" (has not been save yet) in the pre save callback of mongoose model schema?
Yes, there's an isNew
boolean property on a model instance that indicates that. Access it as this.isNew
from your pre save middleware.
var MySchema = new Schema({...});
MySchema.pre('save', function(next) {
if (this.isNew) {
// Hooray!
next()
}
});
