If an error occurs when calling a method of a service (ie missing | ||
parameter, ..) the system returns only a general description of the | ||
problem without details. This is done on purpose to ensure maximum | ||
opacity on implementation details and therefore lower security issue. | ||
|
||
This restriction can be problematic when the services are accessed by an | ||
external system in development. To know the details of an error it is | ||
indeed necessary to have access to the log of the server. It is not | ||
always possible to provide this kind of access. That's why you can | ||
configure the server to run these services in development mode. | ||
|
||
To run the REST API in development mode you must add a new section | ||
'\*\*\[base_rest\]\*\*' with the option '\*\*dev_mode=True\*\*' in the | ||
server config file. | ||
|
||
``` cfg | ||
[base_rest] | ||
dev_mode=True | ||
``` | ||
|
||
When the REST API runs in development mode, the original description and | ||
a stack trace is returned in case of error. **Be careful to not use this | ||
mode in production**. |

This addon is deprecated and not fully supported anymore on Odoo 16. | ||
Please migrate to the FastAPI migration module. See | ||
<https://github.com/OCA/rest-framework/pull/291>. | ||
|
||
This addon provides the basis to develop high level REST APIs for Odoo. | ||
|
||
As Odoo becomes one of the central pieces of enterprise IT systems, it | ||
often becomes necessary to set up specialized service interfaces, so | ||
existing systems can interact with Odoo. | ||
|
||
While the XML-RPC interface of Odoo comes handy in such situations, it | ||
requires a deep understanding of Odoo’s internal data model. When used | ||
extensively, it creates a strong coupling between Odoo internals and | ||
client systems, therefore increasing maintenance costs. | ||
|
||
Once developed, an [OpenApi](https://spec.openapis.org/oas/v3.0.3) | ||
documentation is generated from the source code and available via a | ||
[Swagger UI](https://swagger.io/tools/swagger-ui/) served by your odoo | ||
server at https://my_odoo_server/api-docs. |

## 16.0.1.0.2 (2023-10-07) | ||
|
||
**Features** | ||
|
||
- Add support for oauth2 security scheme in the Swagger UI. If your | ||
openapi specification contains a security scheme of type oauth2, the | ||
Swagger UI will display a login button in the top right corner. In | ||
order to finalize the login process, a redirect URL must be provided | ||
when initializing the Swagger UI. The Swagger UI is now initialized | ||
with a oauth2RedirectUrl option that references a oauth2-redirect.html | ||
file provided by the swagger-ui lib and served by the current addon. | ||
([\#379](https://github.com/OCA/rest-framework/issues/379)) | ||
|
||
## 12.0.2.0.1 | ||
|
||
- validator\_...() methods can now return a cerberus `Validator` object | ||
instead of a schema dictionnary, for additional flexibility (e.g. | ||
allowing validator options such as `allow_unknown`). | ||
|
||
## 12.0.2.0.0 | ||
|
||
- Licence changed from AGPL-3 to LGPL-3 | ||
|
||
## 12.0.1.0.1 | ||
|
||
- Fix issue when rendering the jsonapi documentation if no documentation | ||
is provided on a method part of the REST api. | ||

To add your own REST service you must provides at least 2 classes. | ||
|
||
- A Component providing the business logic of your service, | ||
- A Controller to register your service. | ||
|
||
The business logic of your service must be implemented into a component | ||
(`odoo.addons.component.core.Component`) that inherit from | ||
'base.rest.service' | ||
|
||
Initially, base_rest expose by default all public methods defined in a | ||
service. The conventions for accessing methods via HTTP were as follows: | ||
|
||
- The method `def get(self, _id)` if defined, is accessible via HTTP GET | ||
routes `<string:_service_name>/<int:_id>` and | ||
`<string:_service_name>/<int:_id>/get`. | ||
- The method `def search(self, **params)` if defined, is accessible via | ||
the HTTP GET routes `<string:_service_name>/` and | ||
`<string:_service_name>/search`. | ||
- The method `def delete(self, _id)` if defined, is accessible via the | ||
HTTP DELETE route `<string:_service_name>/<int:_id>`. | ||
- The `def update(self, _id, **params)` method, if defined, is | ||
accessible via the HTTP PUT route `<string:_service_name>/<int:_id>`. | ||
- Other methods are only accessible via HTTP POST routes | ||
`<string:_service_name>` or | ||
`<string:_service_name>/<string:method_name>` or | ||
`<string:_service_name>/<int:_id>` or | ||
`<string:_service_name>/<int:_id>/<string:method_name>` | ||
|
||
``` python | ||
from odoo.addons.component.core import Component | ||
|
||
|
||
class PingService(Component): | ||
_inherit = 'base.rest.service' | ||
_name = 'ping.service' | ||
_usage = 'ping' | ||
_collection = 'my_module.services' | ||
|
||
|
||
# The following method are 'public' and can be called from the controller. | ||
def get(self, _id, message): | ||
return { | ||
'response': 'Get called with message ' + message} | ||
|
||
def search(self, message): | ||
return { | ||
'response': 'Search called search with message ' + message} | ||
|
||
def update(self, _id, message): | ||
return {'response': 'PUT called with message ' + message} | ||
|
||
# pylint:disable=method-required-super | ||
def create(self, **params): | ||
return {'response': 'POST called with message ' + params['message']} | ||
|
||
def delete(self, _id): | ||
return {'response': 'DELETE called with id %s ' % _id} | ||
|
||
# Validator | ||
def _validator_search(self): | ||
return {'message': {'type': 'string'}} | ||
|
||
# Validator | ||
def _validator_get(self): | ||
# no parameters by default | ||
return {} | ||
|
||
def _validator_update(self): | ||
return {'message': {'type': 'string'}} | ||
|
||
def _validator_create(self): | ||
return {'message': {'type': 'string'}} | ||
``` | ||
|
||
Once you have implemented your services (ping, ...), you must tell to | ||
Odoo how to access to these services. This process is done by | ||
implementing a controller that inherits from | ||
`odoo.addons.base_rest.controllers.main.RestController` | ||
|
||
``` python | ||
from odoo.addons.base_rest.controllers import main | ||
|
||
class MyRestController(main.RestController): | ||
_root_path = '/my_services_api/' | ||
_collection_name = my_module.services | ||
``` | ||
|
||
In your controller, \_'root_path' is used to specify the root of the | ||
path to access to your services and '\_collection_name' is the name of | ||
the collection providing the business logic for the requested service/ | ||
|
||
By inheriting from `RestController` the following routes will be | ||
registered to access to your services | ||
|
||
``` python | ||
@route([ | ||
ROOT_PATH + '<string:_service_name>', | ||
ROOT_PATH + '<string:_service_name>/search', | ||
ROOT_PATH + '<string:_service_name>/<int:_id>', | ||
ROOT_PATH + '<string:_service_name>/<int:_id>/get' | ||
], methods=['GET'], auth="user", csrf=False) | ||
def get(self, _service_name, _id=None, **params): | ||
method_name = 'get' if _id else 'search' | ||
return self._process_method(_service_name, method_name, _id, params) | ||
|
||
@route([ | ||
ROOT_PATH + '<string:_service_name>', | ||
ROOT_PATH + '<string:_service_name>/<string:method_name>', | ||
ROOT_PATH + '<string:_service_name>/<int:_id>', | ||
ROOT_PATH + '<string:_service_name>/<int:_id>/<string:method_name>' | ||
], methods=['POST'], auth="user", csrf=False) | ||
def modify(self, _service_name, _id=None, method_name=None, **params): | ||
if not method_name: | ||
method_name = 'update' if _id else 'create' | ||
if method_name == 'get': | ||
_logger.error("HTTP POST with method name 'get' is not allowed. " | ||
"(service name: %s)", _service_name) | ||
raise BadRequest() | ||
return self._process_method(_service_name, method_name, _id, params) | ||
|
||
@route([ | ||
ROOT_PATH + '<string:_service_name>/<int:_id>', | ||
], methods=['PUT'], auth="user", csrf=False) | ||
def update(self, _service_name, _id, **params): | ||
return self._process_method(_service_name, 'update', _id, params) | ||
|
||
@route([ | ||
ROOT_PATH + '<string:_service_name>/<int:_id>', | ||
], methods=['DELETE'], auth="user", csrf=False) | ||
def delete(self, _service_name, _id): | ||
return self._process_method(_service_name, 'delete', _id) | ||
``` | ||
|
||
As result an HTTP GET call to 'http://my_odoo/my_services_api/ping' will | ||
be dispatched to the method `PingService.search` | ||
|
||
In addition to easily exposing your methods, the module allows you to | ||
define data schemas to which the exchanged data must conform. These | ||
schemas are defined on the basis of [Cerberus | ||
schemas](https://docs.python-cerberus.org/en/stable/) and associated to | ||
the methods using the following naming convention. For a method | ||
\`my_method\`: | ||
|
||
- `def _validator_my_method(self):` will be called to get the schema | ||
required to validate the input parameters. | ||
- `def _validator_return_my_method(self):` if defined, will be called to | ||
get the schema used to validate the response. | ||
|
||
In order to offer even more flexibility, a new API has been developed. | ||
|
||
This new API replaces the implicit approach used to expose a service by | ||
the use of a python decorator to explicitly mark a method as being | ||
available via the REST API: `odoo.addons.base_rest.restapi.method`. | ||
|
||
``` python | ||
class PartnerNewApiService(Component): | ||
_inherit = "base.rest.service" | ||
_name = "partner.new_api.service" | ||
_usage = "partner" | ||
_collection = "base.rest.demo.new_api.services" | ||
_description = """ | ||
Partner New API Services | ||
Services developed with the new api provided by base_rest | ||
""" | ||
|
||
@restapi.method( | ||
[(["/<int:id>/get", "/<int:id>"], "GET")], | ||
output_param=restapi.CerberusValidator("_get_partner_schema"), | ||
auth="public", | ||
) | ||
def get(self, _id): | ||
return {"name": self.env["res.partner"].browse(_id).name} | ||
|
||
def _get_partner_schema(self): | ||
return { | ||
"name": {"type": "string", "required": True} | ||
} | ||
|
||
@restapi.method( | ||
[(["/list", "/"], "GET")], | ||
output_param=restapi.CerberusListValidator("_get_partner_schema"), | ||
auth="public", | ||
) | ||
def list(self): | ||
partners = self.env["res.partner"].search([]) | ||
return [{"name": p.name} for p in partners] | ||
``` | ||
|
||
Thanks to this new api, you are now free to specify your own routes but | ||
also to use other object types as parameter or response to your methods. | ||
For example, base_rest_datamodel allows you to use Datamodel object | ||
instance into your services. | ||
|
||
``` python | ||
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 PartnerSearchParam(Datamodel): | ||
_name = "partner.search.param" | ||
|
||
id = fields.Integer(required=False, allow_none=False) | ||
name = fields.String(required=False, allow_none=False) | ||
|
||
|
||
class PartnerShortInfo(Datamodel): | ||
_name = "partner.short.info" | ||
|
||
id = fields.Integer(required=True, allow_none=False) | ||
name = fields.String(required=True, allow_none=False) | ||
|
||
|
||
class PartnerNewApiService(Component): | ||
_inherit = "base.rest.service" | ||
_name = "partner.new_api.service" | ||
_usage = "partner" | ||
_collection = "base.rest.demo.new_api.services" | ||
_description = """ | ||
Partner New API Services | ||

""" | ||
|
||
@restapi.method( | ||
[(["/", "/search"], "GET")], | ||
input_param=restapi.Datamodel("partner.search.param"), | ||
output_param=restapi.Datamodel("partner.short.info", is_list=True), | ||
auth="public", | ||
) | ||
def search(self, partner_search_param): | ||
""" | ||
Search for partners | ||
:param partner_search_param: An instance of partner.search.param | ||
:return: List of partner.short.info | ||
""" | ||
domain = [] | ||
if partner_search_param.name: | ||
domain.append(("name", "like", partner_search_param.name)) | ||
if partner_search_param.id: | ||
domain.append(("id", "=", partner_search_param.id)) | ||
res = [] | ||
PartnerShortInfo = self.env.datamodels["partner.short.info"] | ||
for p in self.env["res.partner"].search(domain): | ||
res.append(PartnerShortInfo(id=p.id, name=p.name)) | ||
return res | ||
``` | ||
|
||
The BaseRestServiceContextProvider provides context for your services, | ||
including authenticated_partner_id. You are free to redefine the method | ||
get_authenticated_partner_id() to pass the authenticated_partner_id | ||
based on the authentication mechanism of your choice. See | ||
base_rest_auth_jwt for an example. | ||
|
||
In addition, authenticated_partner_id is available in record rule | ||
evaluation context. |
