Defining the model representation and order

Models have structural attributes for defining their behavior. These are prefixed with an underscore. The most important attribute of the model is _name, as this defines the internal global identifier. Internally, Odoo uses this _name attribute to create a database table. For example, if you provide _name="library.book", then the Odoo ORM will create the library_book table in the database. And that's why the _name attribute must be unique across Odoo.

There are two other attributes that we can use on a model:

• _rac_name is used to set the field that's used as a representation or title for the records.
• The other one is _order, which is used to set the order in which the records are presented.
