To support pydantic models that map to Odoo models, Pydantic model instances can be created from arbitrary odoo model instances by mapping fields from odoo models to fields defined by the pydantic model. To ease the mapping, the addon provide a utility class `odoo.addons.pydantic.utils.GenericOdooGetter`. .. code-block:: python import pydantic from odoo.addons.pydantic import utils class Group(pydantic.BaseModel): name: str class Config: orm_mode = True getter_dict = utils.GenericOdooGetter class UserInfo(pydantic.BaseModel): name: str groups: List[Group] = pydantic.Field(alias="groups_id") class Config: orm_mode = True getter_dict = utils.GenericOdooGetter user = self.env.user user_info = UserInfo.from_orm(user) See the official `Pydantic documentation`_ to discover all the available functionalities. .. _`Pydantic documentation`: https://pydantic-docs.helpmanual.io/
