Hi !

I'm trying to add a social media link for Pinterest in the configuration setting of the website module (Odoo 12) but I keep getting the error "Field `social_pinterest` does not exist" when I update the module. The code causing the problem is:

<record id="res_config_settings_view_form" model="ir.ui.view">
    <field name="name">res.config.settings.view.form.inherit.website</field>
    <field name="model">res.config.settings</field>
    <field name="inherit_id" ref="website.res_config_settings_view_form"/>
    <field name="arch" type="xml">
        <xpath expr="//div[hasclass('settings')]//field[@name='social_instagram']" position="after">
            <label for="social_pinterest" string="Pinterest" class="col-md-3 o_light_label"/>
            <field name="social_pinterest"/>
        </xpath>
    </field>
</record>

Where, for whatever reason, the field social_pinterest cannot be found by Odoo (as far as I understand). I tried to declare that field, in python, as follow:

class ResConfigSettings(models.TransientModel):
    _inherit = 'res.config.settings'
    
    social_pinterest = fields.Char()

class Website(models.Model):
    _inherit = 'website'
    _name = "website"

    def _default_social_pinterest(self):
        return "test"

    social_pinterest = fields.Char('Pinterest Account', default=_default_social_pinterest)

But this does not work. The module is declared in __init__.py and I even tried to add the field directly into the code of the original website module (and yes, I update it). But nothing works... Any idea of what I'm missing? If I replace 'social_pinterest' in the view code above, by any of the fields already declared in the website module (e.g. social_facebook), then is working fine, so it's definitely a problem with the definition of that field...

Thanks a lot for your help!
