Parameters#

The update method accepts an array of objects, each representing a record to update.

Each object has two properties:

• entity: The entity or record to update. It must be the entire record, which can be retrieved using the find or findAndCount methods.
• update: The properties to update. The keys are the property names of the data model, and the values are the values to update.

In the example above, you retrieve the record to update using the find method. Then, you pass the entire record and the properties to update to the update method.

Returns#

The method returns an array of the updated records.
