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 named foo 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 to base.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 a get_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_phoneDefining 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 & 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"/>
