Odoo POS enables seamless integration with accounting inventory and customer relationship management applications, resulting in a unified productive operating system. in this blog we are going to explore how to load models & fields to POS in Odoo18.

In earlier versions of Odoo, integrating custom models into the POS system involved complex customization, requiring numerous technical steps to modify both the frontend and backend components.The pos.load.mixin feature in Odoo18 simplifies model loading into POS delivery systems without requiring interface modification.

How to Load Models into Your POS System

It took a lot of technical work, including altering the frontend and backend components, to load custom models into the POS system in earlier iterations of Odoo. By adding the pos.load.mixin, Odoo18 streamlines this procedure by enabling models to be loaded straight into the POS without requiring significant alterations to the POS interface.

We have developed a model named CustomModel in this code. Adding this model to the POS system is the next stage. It is necessary to inherit the pos.session model and override its _load_pos_data_models function in order to accomplish this. To return the name of the model that must be loaded into the POS, this function should be changed.

The POS system now has our customized model loaded. By using your POS’s this. models console, we can verify this.

How to Load Fields into Your POS System

In Odoo18, adding fields from a model to the POS is really simple. To achieve this, we need to add a new function called _load_pos_data_fields to our custom model, which returns the fields we wish to add to the POS. The POS now has our fields loaded as well. Here’s how to load custom models and fields into the Odoo18 POS system.

How to Load Fields into an Existing Model in POS

Field Loading into existing models in Odoo18 provides both ease of use and efficient implementation. Odoo18 includes performance improvements that facilitate more efficient model extension and custom field addition processes. The _load_pos_data_fields function brings custom fields into the Point of Sale (POS). The same operation function serves the loading task.

To add fields to an existing model in Odoo POS, you need to override the _load_pos_data_fields function.

This procedure shows how to successfully include fields and custom models into the Odoo POS system. Businesses can adapt their operations to meet particular needs by utilizing the POS module’s upgraded features. In the end, this adaptability improves overall efficiency and user happiness by guaranteeing that the POS system stays flexible, expandable, and prepared to manage a variety of business circumstances.
