Exploring dynamoosev2:
T extends Document;
model: ModelType<T>;
const attributes: string[] = model.schemas[0].attributes();Is there a different approach to retrieve attribute names from the model in dynamoose v3?
Transitioning to dynamoose v3:
T extends Item;
model: ModelType<T>;
const attributes: string[] = model.schemas[0].attributes();An error emerges stating:
Property 'schemas' does not exist on type 'ModelType<T>'When I was working with Dynamoose 3, I faced a similar issue. Below is a demonstration of how to retrieve model attributes:
import * as dynamoose from "dynamoose";
import {Item} from "dynamoose/dist/Item";
// Defining a strongly typed model
class Person extends Item {
id: number;
name: string;
}
const PersonModel = dynamoose.model<Person>("Person", {"id": Number, "name": String});
If you try to create a new record with an undeclared field like surname, TypeScript will show an error.
CatModel.create({"id": 1, "surname": "string"});
After creating or fetching the model, your IDE will provide you with the correct attributes.
Example 1:
const Person = await PersonModel.get(1);
//console.log(Person.id)
//console.log(Person.name)
Example 2:
const Person = await PersonModel.create({id: "1", name: "John" })
//console.log(Person.id)
//console.log(Person.name)
Accessing internal properties directly is not possible in dynamoose v3, as they are only accessible through the private function #getInternalProperties.
To work around this limitation, you can export both the Model and schema definition like so:
export const UserSchema: SchemaDefinition = {
id: {
type: String,
required: true,
hashKey: true,
},
};
export const UserModel = dynamoose.model(
"TableName",
[new dynamoose.Schema(UserSchema, { timestamp: true })],
{
// some setting for model
},
);
