How to Add Custom Fields to Configuration Settings in Odoo 18
- 1. How to Add Custom Fields to Configuration Settings in Odoo 18 Enterprise
- 2. Enterprise Introduction In Odoo, adding custom fields to Configuration Settings actually means adding fields to the res.config.settings model. This model is designed for system configuration, allowing users to define global settings for various modules, such as the Sale, Purchase. Adding custom fields in res.config.settings can make the system highly customizable and improve user experience by adapting Odoo to specific business needs. Lets see how a new field is added using the Odoo 18 code
- 3. Enterprise The ResConfigSettings model in Odoo is transient, meaning that its data is regularly cleaned up. The fields in res.config.settings are often linked to ir.config_parameter, which stores the configuration values. When we add a custom field, we need to ensure its value is properly saved in the configuration parameters so that it persists across sessions. We use the attribute config_parameter while defining the field as config_parameter=module_name.field_name
- 4. Enterprise Adding fields to the ResConfigSettings model: Suppose our module name is sales_custom, lets create a new field for setting a minimum sale amount for the Sales in Odoo 18. For that, first, we need to inherit the res.config.settings model and we define two fields here as from odoo import api, fields, models class ResConfigSettings(models.TransientModel): """Inheriting ResConfigSettings to add fields and functions""" _inherit = 'res.config.settings' set_order_minimum_amount = fields.Boolean(string='Set Minimum Sale Amount', config_parameter=sales_custom.set_order_minimum_amount') order_minimum_amount = fields.Float( string='Minimum Sale Amount', config_parameter=sales_custom.order_minimum_amount')
- 5. Enterprise Note that, we created a transient model using class ResConfigSettings(models.TransientModel): And the boolean field set_order_minimum_amount is used to enable the feature on the configurations settings page and the floating field order_minimum_amount is shown and hidden based on that boolean fields value. The module name is sales_custom so that for those two fields, we used the config_parameter attribute as config_parameter=sales_custom.set_order_minimum_amount' and config_parameter=sales_custom.order_minimum_amount'
- 6. Enterprise Adding the fields to the view of ResConfigSettings While adding custom fields to a view, we can inherit the existing view and specify their position using the <xpath> tag. To add custom fields to the Sale modules settings, we should inherit the view sale.res_config_settings_view_form and indicate where you want these fields to appear. We can add these custom fields under the Pricing tab of Sale modules setting almost near here
- 7. Enterprise The code for adding the view inheritance is as <?xml version="1.0" encoding="UTF-8" ?> <odoo> <record id="res_config_settings_view_form" model="ir.ui.view"> <field name="name"> res.config.settings.view.form.inherit.sales.custom </field> <field name="model">res.config.settings</field> <field name="inherit_id" ref="sale.res_config_settings_view_form"/> <field name="arch" type="xml"> <xpath expr="//setting[@id=discount_sale_order_lines]" position="after"> <setting id="sale_order_minimum_amount" documentation=" https://www.odoo.com/documentation/18.0" title="User can set the minimum amount for the sale orders." help="For the minimum sale amount for all the orders"> <field name="set_order_minimum_amount"/> <div class="content-group" invisible="not set_order_minimum_amount"> <div class="mt16"> <label for="order_minimum_amount"/> <field name="order_minimum_amount"/> </div> </div> </setting> </xpath> </field> </record> </odoo>
- 8. Enterprise This makes the new boolean field to be visible on the settings page as
- 9. Enterprise Upon enabling that, it makes the float field to give the amount to be visible on the settings page as With these kind of setup and configurations, we can make use of these settings field in any other Odoo modules and control the workflow as we need
