Class ManyArray

public

Extends: EmberObject

Uses: DeprecatedEvented , Ember.MutableArray

Defined in: ../model/addon/-private/system/many-array.js:15

Module: @ember-data/store

A ManyArray is a MutableArray that represents the contents of a has-many relationship.

The ManyArray is instantiated lazily the first time the relationship is requested.

This class is not intended to be directly instantiated by consuming applications.

Inverses

Often, the relationships in Ember Data applications will have an inverse. For example, imagine the following models are defined:

app/models/post.js

import Model, { hasMany } from '@ember-data/model';

export default class PostModel extends Model {
  @hasMany('comment') comments;
}

app/models/comment.js

import Model, { belongsTo } from '@ember-data/model';

export default class CommentModel extends Model {
  @belongsTo('post') post;
}

If you created a new instance of Post and added a Comment record to its comments has-many relationship, you would expect the comment's post property to be set to the post that contained the has-many.

We call the record to which a relationship belongs-to the relationship's owner.

createRecord (hash) Model public

Module: @ember-data/store

Defined in ../model/addon/-private/system/many-array.js:362

hash: Object
returns: Model; record

Create a child record within the owner

reload public

Module: @ember-data/store

Defined in ../model/addon/-private/system/many-array.js:304

Reloads all of the records in the manyArray. If the manyArray holds a relationship that was originally fetched using a links url Ember Data will revisit the original links url to repopulate the relationship.

If the manyArray holds the result of a store.query() reload will re-run the original query.

Example

let user = store.peekRecord('user', '1')
await login(user);

let permissions = await user.permissions;
await permissions.reload();

save PromiseArray public

Module: @ember-data/store

Defined in ../model/addon/-private/system/many-array.js:331

returns: PromiseArray; promise

Saves all of the records in the ManyArray.

Example

let inbox = await store.findRecord('inbox', '1');
let messages = await inbox.messages;
messages.forEach((message) => {
  message.isRead = true;
});
messages.save();
