Dear all,

I am having a problem on Odoo v12 on saving data on "res.config.settings" model.

I have inherited the model and defined my custom fields:

       class ResConfigSettings(models.TransientModel):
           _inherit = ['res.config.settings']
           #My custom fields
           my_custom_field1_id = fields.Many2one('res.partner', string='For Customer')
           my_custom_field2_id = fields.Many2one('res.partner', string='For Supplier')

The above code is the only code I have on the module .py.

For the UI I have inherited the "res_config_settings_view_form" on the corresponding XML file.

      <record id="res_config_settings_mymodule_form" model="ir.ui.view">
      <field name="name">Config Settings for My Module</field>
      <field name="model">res.config.settings</field>
      <field name="priority" eval="90"/>
      <field name="inherit_id" ref="base.res_config_settings_view_form"/>
      <field name="arch" type="xml">
           <xpath expr="//div[hasclass('settings')]" position="inside">
           <div class="app_settings_block" data-string="MyModule" string="MyModule" data-key="mymodule" groups="account.group_account_manager">
           <t groups="account.group_account_user">
                <h2>My Module Defaults</h2>
                <div class="row mt16 o_settings_container">
                <div class="col-12 col-lg-6 o_setting_box" title="These values are default values the module">
                <div class="o_setting_left_pane">
                </div>
                     <div class="o_setting_right_pane">
                     <span class="o_form_label">Default Data</span>
                     <span class="fa fa-lg fa-building-o" title="Values set here are company-specific." aria-label="Values set here are company-specific." groups="base.group_multi_company" role="img"/>
                     <div class="text-muted">
                     Default values for module
                     </div>
                     <div class="content-group">
                     <div class="row mt16">
                          <label string="Customer" for="my_custom_field1_id" class="col-lg-3 o_light_label"/>
                          <field name="my_custom_field1_id" domain="[('customer', '=', 'True'), ('company_id', '=', company_id)]"/>
                     </div>
                     <div class="row mt16">
                          <label string="Supplier" for="my_custom_field2_id" class="col-lg-3 o_light_label"/>
                          <field name="my_custom_field2_id" domain="[('supplier', '=', 'True'), ('company_id', '=', company_id)]"/>
                     </div>
                     </div>
                     </div>
                     </div>
                     </div>
           </t>
           </div>
           </xpath>
      </field>
      </record>

Everything seems to be working fine and I get no errors and I can see the new "app_settings_block" created for My Module with both new fields and they work for the domain I set for each field.

The problem I have is that when I set a value to any of the fields and click on the "Save" button, the data is simple not saved into the database.

I am sure I am working with correct user/group and have full access to the system.

What could be the problem?

Any idea?

Thank you all in advance

Best regards

Paulo
