  • Defining custom settings in Odoo

    Unfortunately Odoo documentation doesn’t seem to include any information about adding new configuration options to Odoo. So let’s fill in the gaps.

    Defining a model

    First of all, you need to define a new model inheriting from res.config.settings:

    class YourSettings(models.TransientModel):
        _inherit = 'res.config.settings'
        _name = 'your.config.settings'

    It’s a TransientModel, also known as a wizard. Do not expect it to permanently hold the values. TransientModels inherently store values on a temporary basis only. You need other means to make them permanent.

    Fortunately res.config.settings makes this easy. First of all, you need to add some fields to your TransientModel - one for every setting option you want to define. Odoo comes with built-in support for four different kinds of settings. It distinguishes between them based on the field names.

    “Default” settings
    The value of a field named default_foo will be set as a default value for a field namedfoo on a model given as a default_model argument.

    class YourSettings(models.TransientModel):
        _inherit = 'res.config.settings'
        _name = 'your.config.settings'
    
        default_name = fields.Char(default_model='your.other.model')

    This will make the value of default_name field the global default value of a field name in model your.other.model.

    “Group” settings
    Boolean fields named group_foo take two arguments: group (defaults tobase.group_user) and implied_group. If the value of such field is true, the group defined in group gain all implied_group’s permissions. This is exactly the same as adding a group to implied_ids field on another group’s object (which as far as I know is also an undocumented feature). This is useful for controlling which groups of users have access to a feature.

    class YourSettings(models.TransientModel):
        _inherit = 'res.config.settings'
        _name = 'your.config.settings'
    
        group_kill = fields.Boolean(
            group='your.secret_agents',
            implied_group='your.licence_to_kill'
        )

    “Module” settings
    Boolean fields named module_foo, when enabled will trigger installation of a module named foo.

    class YourSettings(models.TransientModel):
        _inherit = 'res.config.settings'
        _name = 'your.config.settings'
    
        # if enabled will install "spies" module
        module_spies = fields.Boolean()

    Other settings
    By default the values of other fields will be discarded, but you change that by implementing your own means of saving them. Just define a method named set_foo(where foo is an arbitrary string). You can also set initial values of such fields using aget_default_foo method (the exact form of foo is once again irrelevant).

    For example if you want to use settings to control the name and phone number of a company linked to the current user:

    class YourSettings(models.TransientModel):
        _inherit = 'res.config.settings'
        _name = 'your.config.settings'
    
        company_name = fields.Char()
        company_phone = fields.Char()
    
        @api.model
        def get_default_company_values(self, fields):
        """
        Method argument "fields" is a list of names
        of all available fields.
        """
            company = self.env.user.company_id
            return {
                'company_name': company.name,
                'company_phone': company.phone,
            }
    
        @api.one
        def set_company_values(self):
            company = self.env.user.company_id
            company.name = self.company_name
            company.phone = self.company_phone

    Defining a view

    Then you just need to define a view for your settings. Let’s use the previous example:

    <record id="your_configuration" model="ir.ui.view">
        <field name="name">Your configuration</field>
        <field name="model">your.config.settings</field>
        <field name="arch" type="xml">
            <form string="Your configuration" class="oe_form_configuration">
                <header>
                    <button string="Save" type="object"
                        name="execute" class="oe_highlight"/>
                    or
                    <button string="Cancel" type="object"
                        name="cancel" class="oe_link"/>
                </header>
                <group string="Company">
                    <label for="id" string="Name &amp; Phone"/>
                    <div>
                        <div>
                            <label for="company_name"/>
                            <field name="company_name"/>
                        </div>
                        <div>
                            <label for="company_phone"/>
                            <field name="company_phone"/>
                        </div>
                    </div>
                </group>
            </form>
        </field>
    </record>
    <record id="your_settings_action" model="ir.actions.act_window">
        <field name="name">Your configuration</field>
        <field name="res_model">your.config.settings</field>
        <field name="view_id" ref="your_configuration"/>
        <field name="view_mode">form</field>
        <field name="target">inline</field>
    </record>

    …and of course don’t forget to make a new entry in the settings menu:

    <menuitem id="your_settings_menu" name="Your settings"
        parent="base.menu_config" action="your_settings_action"/>
