How to Load Custom Field to POS in Odoo 17 - Odoo 17 Slides
- 1. How to Load Custom Field to POS in Odoo 17 Enterprise
- 2. Introduction Enterprise This slide explains how to load custom fields you've created into the Odoo 17 Point-of-Sale (POS) interface.
- 3. Enterprise There are two main approaches: 1. Loading Fields to Existing Models 2. Loading a Custom Model to the POS
- 4. Enterprise 1. Loading Fields to Existing Models This approach involves extending the functionalities of existing POS models (e.g., product.product) to include your custom field. Steps: 1. Create the Custom Field: In your custom module, define the custom field using Odoo's field types (e.g., char, float, boolean) within your model definition.
- 5. Enterprise 2. Extend the _loader_params_<model_name> Function: Create a function named _loader_params_<model_name> (replace <model_name> with the actual model name, e.g., product.product) by inheriting the pos.session model. This function returns a dictionary with a key named "search_params". The "search_params" value should be another dictionary with two keys: "domains" (optional): A list of domain filters to apply when searching for the model (relevant for custom filtering based on your field). "fields": A list containing your custom field name to ensure it's loaded in the POS view.
- 6. Enterprise 3. (Optional) Override _get_pos_ui_<model_name> Function (Advanced): If you need to manipulate the retrieved data before it reaches the POS UI, you can define a function named _get_pos_ui_<model_name> . This function takes a record (e.g., product object) as input and can modify or format the custom field value before returning it.
- 7. Enterprise Example: from odoo import models # Assuming your custom field is named "custom_field" on the "product.product" model class PosSession(models.Model): _inherit = 'pos.session' def _loader_params_product_product(self): result = super()._loader_params_product_product() result['search_params']['fields'].append(custom_field) return result
- 8. Enterprise 2. Loading a Custom Model to the POS This approach involves creating a completely new model for your custom data and then loading it into the POS interface. Steps: ● Load the model to the pos Inherit the pos.session model and load the custom model to the pos as follows
- 9. Enterprise class PosSession(models.Model): _inherit = 'pos.session' def _pos_ui_models_to_load(self): result = super()._pos_ui_models_to_load() result += [ custom.model ] return result
- 10. Enterprise Create a function named _loader_params_<model_name> (replace <model_name> with the actual model name, e.g., custom.model). def _loader_params_custom_model(self): return { 'search_params': { 'domain': [], 'fields': [ ‘field1’, ‘field2’,’field3’, ‘field4’ ], }, }
- 11. Enterprise define a function named _get_pos_ui_<model_name> . This function takes a record as input and can modify or format the custom field value before returning it. def _get_pos_ui_custom_model(self, params): return self.env[custom.model].search_read(**params['search_params' ])
- 12. Enterprise Now create a js file and add the code below to load the custom model data into pos /** @odoo-module */ import { patch } from "@web/core/utils/patch"; import { PosStore } from "@point_of_sale/app/store/pos_store"; patch(PosStore.prototype, { async _processData(loadedData) { await super._processData(...arguments); this.model = loadedData["custom.model"]; } }, });
- 13. Enterprise Now the custom model and its data will be available in the point of sale interface
