Odoo 12 Development Essentials - Fourth Edition

Methods for writing model data

The ORM provides three methods for the three basic write operations, shown as follows:

• <Model>.create(values) creates a new record on the model. It returns the created record.
• <Recordset>.write(values) updates field values on the recordset. It returns nothing.
• <Recordset>.unlink() deletes the records from the database. It returns nothing.

The values argument is a dictionary, mapping field names to values to write. The methods are decorated with @api.multi, except for the create() method, which is decorated with @api.model.

Changed in Odoo 12  The create() method now also allows to create records in batches. This is done by passing as argument a list of dictionary objects, instead of a single dictionary object. ...
