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.

## 12.0.1.0.0

First official version. The addon has been incubated into the
[Shopinvader repository](https://github.com/akretion/odoo-shopinvader)
from Akretion. For more information you need to look at the git log.

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
Services developed with the new api provided by base_rest
"""

@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.
