This module takes advantage of the concepts introduced in the `datamodel` module to offer mechanisms similar to
|
|
(a subset of) the `ModelSerializer` in Django REST Framework. That is, use the definition of the Odoo model to
|
|
partially automate the definition of a corresponding `Datamodel` class.
|
|
|
|
.. IMPORTANT::
|
|
This is an alpha version, the data model and design can change at any time without warning.
|
|
Only for development or testing purpose, do not use in production.

Usage
|
|
=====
|
|
|
|
:code:`ModelSerializer` class
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The :code:`ModelSerializer` class inherits from the :code:`Datamodel` class and adds functionalities. Therefore any
|
|
class inheriting from :code:`ModelSerializer` can be used the exact same way as any other :code:`Datamodel`.
|
|
|
|
Basic usage
|
|
***********
|
|
|
|
Here is a basic example::
|
|
|
|
from odoo.addons.model_serializer.core import ModelSerializer
|
|
|
|
class PartnerInfo(ModelSerializer):
|
|
_name = "partner.info"
|
|
_model = "res.partner"
|
|
_model_fields = ["id", "name", "country_id"]
|
|
|
|
The result is equivalent to the following :code:`Datamodel` classes::
|
|
|
|
from marshmallow import fields
|
|
|
|
from odoo.addons.datamodel.core import Datamodel
|
|
from odoo.addons.datamodel.fields import NestedModel
|
|
|
|
|
|
class PartnerInfo(Datamodel):
|
|
_name = "partner.info"
|
|
|
|
id = fields.Integer(required=True, allow_none=False, dump_only=True)
|
|
name = fields.String(required=True, allow_none=False)
|
|
country = NestedModel("_auto_nested_serializer.res.country")
|
|
|
|
|
|
class _AutoNestedSerializerResCountry(Datamodel):
|
|
_name = "_auto_nested_serializer.res.country"
|
|
|
|
id = fields.Integer(required=True, allow_none=False, dump_only=True)
|
|
display_name = fields.String(dump_only=True)
|
|
|
|
|
|
Overriding fields definition
|
|
****************************
|
|
|
|
It is possible to override the default definition of fields as such::
|
|
|
|
from odoo.addons.model_serializer.core import ModelSerializer
|
|
|
|
class PartnerInfo(ModelSerializer):
|
|
_name = "partner.info"
|
|
_model = "res.partner"
|
|
_model_fields = ["id", "name", "country_id"]
|
|
|
|
country_id = NestedModel("country.info")
|
|
|
|
class CountryInfo(ModelSerializer):
|
|
_name = "country.info"
|
|
_model = "res.country"
|
|
_model_fields = ["code", "name"]
|
|
|
|
In this example, we override a :code:`NestedModel` but it works the same for any other field type.
|
|
|
|
(De)serialization
|
|
*****************
|
|
|
|
:code:`ModelSerializer` does all the heavy-lifting of transforming a :code:`Datamodel` instance into the corresponding
|
|
:code:`recordset`, and vice-versa.
|
|
|
|
To transform a recordset into a (list of) :code:`ModelSerializer` instance(s) (serialization), do the following::
|
|
|
|
partner_info = self.env.datamodels["partner.info"].from_recordset(partner)
|
|
|
|
This will return a single instance; if your recordset contains more than one record, you can get a list of instances
|
|
by passing :code:`many=True` to this method.
|
|
|
|
|
|
To transform a :code:`ModelSerializer` instance into a recordset (de-serialization), do the following::
|
|
|
|
partner = partner_info.to_recordset()
|
|
|
|
Unless an existing partner can be found (see below), this method **creates a new record** in the database. You can avoid
|
|
that by passing :code:`create=False`, in which case the system will only create them in memory (:code:`NewId` recordset).
|
|
|
|
In order to determine if the corresponding Odoo record already exists or if a new one should be created, the system
|
|
checks by default if the :code:`id` field of the instance corresponds to a database record. This default behavior can be
|
|
modified like so::
|
|
|
|
class CountryInfo(ModelSerializer):
|
|
_name = "country.info"
|
|
_model = "res.country"
|
|
_model_fields = ["code", "name"]
|
|
|
|
def get_odoo_record(self):
|
|
if self.code:
|
|
return self.env[self._model].search([("code", "=", self.code)])
|
|
return super().get_odoo_record()
|
