# Writing Data

# create

To create records on the server and also store it locally, use the create method. Pass it an object containing an attributes object. This is similar to a JSON:API record, but you don't need to specify the type -- the store will add the type.

const recordData = {
  attributes: {
    title: 'My Widget',
  },
};
store.create(recordData);

You can also save relationships by providing a relationships attribute, just like in the JSON:API spec:

const recordData = {
  attributes: {
    title: 'My Widget',
  },
  relationships: {
    category: {
      data: {
        type: 'categories',
        id: 42,
      },
    },
  },
};
store.create(recordData);

# save

The returned record objects are instances of Record. To update records, mutate attributes, then call save() on the record:

const widget = store.byId({ id: 42 });
widget.attributes.title = 'Updated Title';
widget.save();

# update

save() will persist all attributes and relationships on the record to the server. If you only want to persist certain attributes or relationships, you can call update(), passing them in. The new values will be saved to the server and then updated in the record itself:

const widget = store.byId({ id: 42 });
widget.update({
  attributes: { title: 'Updated Title' },
});

# delete

To delete, call delete() on a record:

const widget = store.byId({ id: 42 });
widget.delete();
