Custom ID Field in Mongoose
- ObjectId is suitable for most scenarios, but there are cases where custom IDs are preferred, such as using sequential numbers or UUIDs for readability or integration with external systems.
- To define a custom ID field in Mongoose, we can explicitly specify the _id field in our schema.
// Define a new mongoose schema for the custom model
const customSchema = new mongoose.Schema({
customId: String, // Define a field for the customId of type String
name: String, // Define a field for the name of type String
age: Number // Define a field for the age of type Number
});
// Create a new mongoose model based on the custom schema
const CustomModel = mongoose.model('CustomModel', customSchema); // 'CustomModel' is the model name, and customSchema is the schema
// Create a new instance of the CustomModel with customId '123abc', name 'Alice', and age 25
const customInstance = new CustomModel({ customId: '123abc', name: 'Alice', age: 25 });
// Log the newly created customInstance
console.log(customInstance); // { _id: '123abc', name: 'Alice', age: 25 }
