Class Model
Extends: | EmberObject |
---|---|
Uses: | EmberData.DeprecatedEvented |
Defined in: | ../model/addon/index.ts:1 |
Module: | @ember-data/model |
In EmberData a Model
is a class defining the attributes and relationships of a specific resource type
(model name). In this sense it represents a static "schema".
Data for individual resources fetched from your API is presented to the UI via instances of the Model
s you define.
An instantiated Model
is referred to as a record
.
When we refer to the ModelClass
we are referring to the class definition and the static schema methods present on it.
When we refer to a record
we refer to a specific class instance presenting the resource data for a given type
and id
.
Defining a Model
app/models/person.js
import Model, { attr, belongsTo, hasMany } from '@ember-data/model'; export default class PersonModel extends Model { @attr name; @belongsTo('pet', { inverse: 'owners', async: false }) dog; @hasMany('person', { inverse: 'friends', async: true }) friends; }
modelName convention
By convention, the name of a given model (its type
) matches the name of the file in the app/models
folder and should be lowercase, singular and dasherized. @mainName @ember-data/model @tag main
