Odoo 12 - Development res.config.settings problem

Question

I need help. I am developing a module in version 12 of odoo. I currently have the model created along with the view. However, the general options panel view does not load but is created.

Here my code:

Model:

    # -*- coding: utf-8 -*-
from odoo import models, fields, api
#Campos adicionales en el formulario de contrato
class EmployeeFields(models.Model):
    _inherit = 'hr.contract'
    aport_asoc = fields.Float(string="Porcentaje de Aporte", digits=(2,2), default=0, help="Porcentaje del sueldo que aporta el asociado a la caja de ahorro")
#Campos para la seccion de configuracion
class BoxConfig(models.TransientModel):
    _inherit = 'res.config.settings'
    s_minimo = fields.Float(string="Sueldo Minimo", digits=(25,2), default=0, help="Sueldo minimo completo o monto general del cual se debita el porcentaje de aporte")
    emp_asoc = fields.Boolean(string="Empresa aporta igual que empleado", default=0, help="Marque esta opcion si la empresa aporta la misma cantidad que cada empleado")
    aport_general = fields.Float(string="Cantidad de aporte general", default=0, help="Asigna a Asociados y Empresa el mismo porcentaje de aporte para todos, dejar en 0 para que no tome ningun valor")
    aport_emp = fields.Float(string="Aporte Empresa", digits=(2,2), default=0, help="Porcentaje de aporte adicional que agrega la empresa")

View:

<odoo>
    <data>

        <!-- Campo agregado al modelo de datos de contratos -->
        <record model="ir.ui.view" id="contract_fields_add">
            <field name="name">contract.fields.add</field>

                    </group>

            <field name="arch" type="xml">
                <xpath expr="//div[hasclass('settings')]" position="inside">
                    <div class="app_settings_block o_not_app" data_string="Caja de Ahorro" string="Caja de Ahorro" data_key="box">

                                </div>
                            </div>
                        </div>
                    </div>
                </xpath>
            </field>
        </record>
    </data>
    <record id="action_box_config_settings" model="ir.actions.act_window">
        <field name="name">Settings</field>
        <field name="type">ir.actions.act_window</field>
        <field name="res_model">res.config.settings</field>
        <field name="view_id" ref="box_config_settings"/>
        <field name="view_mode">form</field>
        <field name="target">inline</field>
        <field name="context">{'module' : box}</field>
    </record>

</odoo>

When you update the module it does not throw an error, however when I enter the general settings screen I do not see it in the list.

In developer mode reviewing the form view of the res.config.settings model in inherited views I see that my model exists. However, the form is not visible

I have already tried several solutions and so far this one that creates my view is the one that is closest to being the right one. Please tell me what I am doing wrong or what I need for the view to be present in the configuration section.

Answer 1

Try this :

<record id="box_config_settings" model="ir.ui.view">
    <field name="name">res.config.settings.view.box_config</field>
    <field name="model">res.config.settings</field>
    <field name="priority" eval="25" />
    <field name="inherit_id" ref="sale.res_config_settings_view_form" />
        <field name="arch" type="xml">
            <xpath expr="//div[@id='sale_config_online_confirmation_sign']"
                position="before">
            <div class="col-xs-12 col-md-6 o_setting_box">
                    <div class="o_setting_left_pane">
                        <field name="s_minimo" />
                    </div>
                    <div class="o_setting_right_pane">
                        <label for="s_minimo" />
                    </div>
                </div>
        </xpath>
    </field>
</record>

Note : this view will be inherited in Sales Section of General Setting
