# Datamodel

This addon allows you to define simple data models supporting serialization/deserialization to/from json

Datamodels are Marshmallow models classes that can be inherited as Odoo Models.

# Usage

To define your own datamodel you just need to create a class that inherits from `odoo.addons.datamodel.core.Datamodel`

    from marshmallow import fields

    from odoo.addons.base_rest import restapi
    from odoo.addons.component.core import Component
    from odoo.addons.datamodel.core import Datamodel

    class PartnerShortInfo(Datamodel):
        _name = "partner.short.info"

        id = fields.Integer(required=True, allow_none=False)
        name = fields.String(required=True, allow_none=False)

    class PartnerInfo(Datamodel):
        _name = "partner.info"
        _inherit = "partner.short.info"

        street = fields.String(required=True, allow_none=False)
        street2 = fields.String(required=False, allow_none=True)
        zip_code = fields.String(required=True, allow_none=False)
        city = fields.String(required=True, allow_none=False)
        phone = fields.String(required=False, allow_none=True)
        is_componay = fields.Boolean(required=False, allow_none=False)

As for odoo models, you can extend the base datamodel by inheriting of base.

    class Base(Datamodel):
        _inherit = "base"

        def _my_method(self):
            pass

Datamodels are available through the datamodels registry provided by the Odoo’s environment.

    class ResPartner(Model):
        _inherit = "res.partner"

        def _to_partner_info(self):
            PartnerInfo = self.env.datamodels["partner.info"]
            partner_info = PartnerInfo(partial=True)
            partner_info.id = partner.id
            partner_info.name = partner.name
            partner_info.street = partner.street
            partner_info.street2 = partner.street2
            partner_info.zip_code = partner.zip
            partner_info.city = partner.city
            partner_info.phone = partner.phone
            partner_info.is_company = partner.is_company
            return partner_info

The Odoo’s environment is also available into the datamodel instance.

    class MyDataModel(Datamodel):
        _name = "my.data.model"

        def _my_method(self):
            partners = self.env["res.partner"].search([])

Warning

The env property into a Datamodel instance is mutable. IOW, you can’t rely on information (context, user) provided by the environment. The env property is a helper property that give you access to the odoo’s registry and must be use with caution.
