Web Service API
===============
Odoo is usually extended internally via modules, but many of its features and
all of its data are also available from the outside for external analysis or
integration with various tools. Part of the :ref:`reference/orm/model` API is
easily available over XML-RPC_ and accessible from a variety of languages.
.. Odoo XML-RPC idiosyncracies:
* uses multiple endpoint and a nested call syntax instead of a
"hierarchical" server structure (e.g. ``openerp.res.partner.read()``)
* uses its own own manual auth system instead of basic auth or sessions
(basic is directly supported the Python and Ruby stdlibs as well as
ws-xmlrpc, not sure about ripcord)
* own auth is inconvenient as (uid, password) have to be explicitly passed
into every call. Session would allow db to be stored as well
These issues are especially visible in Java, somewhat less so in PHP

Configuration
-------------
If you already have an Odoo server installed, you can just use its
parameters
.. warning::
For Odoo Online instances (<domain>.odoo.com), users are created without a
*local* password (as a person you are logged in via the Odoo Online
authentication system, not by the instance itself). To use XML-RPC on Odoo
Online instances, you will need to set a password on the user account you
want to use:
* Log in your instance with an administrator account
* Go to :menuselection:`Settings --> Users --> Users`
* Click on the user you want to use for XML-RPC access
* Click the :guilabel:`Change Password` button
* Set a :guilabel:`New Password` value then click
:guilabel:`Change Password`.
The *server url* is the instance's domain (e.g.
*https://mycompany.odoo.com*), the *database name* is the name of the
instance (e.g. *mycompany*). The *username* is the configured user's login
as shown by the *Change Password* screen.

.. note::
These examples use the `Ripcord <https://code.google.com/p/ripcord/>`_
library, which provides a simple XML-RPC API. Ripcord requires that
`XML-RPC support be enabled
<http://php.net/manual/en/xmlrpc.installation.php>`_ in your PHP
installation.
Since calls are performed over
`HTTPS <http://en.wikipedia.org/wiki/HTTP_Secure>`_, it also requires that
the `OpenSSL extension
<http://php.net/manual/en/openssl.installation.php>`_ be enabled.

The examples do not include imports as these imports couldn't be
pasted in the code.
Logging in
----------
Odoo requires users of the API to be authenticated before they can query most
data.
The ``xmlrpc/2/common`` endpoint provides meta-calls which don't require
authentication, such as the authentication itself or fetching version
information. To verify if the connection information is correct before trying
to authenticate, the simplest call is to ask for the server's version. The
authentication itself is done through the ``authenticate`` function and
returns a user identifier (``uid``) used in authenticated calls instead of
the login.
.. rst-class:: setup doc-aside
.. switcher::
.. code-block:: python
common = xmlrpclib.ServerProxy('{}/xmlrpc/2/common'.format(url))
common.version()
.. code-block:: ruby
common = XMLRPC::Client.new2("#{url}/xmlrpc/2/common")
common.call('version')
.. code-block:: php
$common = ripcord::client("$url/xmlrpc/2/common");
$common->version();
.. code-block:: java
final XmlRpcClientConfigImpl common_config = new XmlRpcClientConfigImpl();
common_config.setServerURL(
new URL(String.format("%s/xmlrpc/2/common", url)));

.. code-block:: java
int uid = (int)client.execute(
common_config, "authenticate", asList(
db, username, password, emptyMap()));
Calling methods
===============
The second endpoint is ``xmlrpc/2/object``, is used to call methods of odoo
models via the ``execute_kw`` RPC function.
Each call to ``execute_kw`` takes the following parameters:
* the database to use, a string
* the user id (retrieved through ``authenticate``), an integer
* the user's password, a string
* the model name, a string
* the method name, a string
* an array/list of parameters passed by position
* a mapping/dict of parameters to pass by keyword (optional)
.. container:: doc-aside
For instance to see if we can read the ``res.partner`` model we can call
``check_access_rights`` with ``operation`` passed by position and
``raise_exception`` passed by keyword (in order to get a true/false result
rather than true/error):
.. rst-class:: setup
.. switcher::
.. code-block:: python
models = xmlrpclib.ServerProxy('{}/xmlrpc/2/object'.format(url))
models.execute_kw(db, uid, password,
'res.partner', 'check_access_rights',
['read'], {'raise_exception': False})
.. code-block:: ruby
models = XMLRPC::Client.new2("#{url}/xmlrpc/2/object").proxy
models.execute_kw(db, uid, password,
'res.partner', 'check_access_rights',
['read'], {raise_exception: false})
.. code-block:: php
$models = ripcord::client("$url/xmlrpc/2/object");
$models->execute_kw($db, $uid, $password,
'res.partner', 'check_access_rights',
array('read'), array('raise_exception' => false));
.. code-block:: java
final XmlRpcClient models = new XmlRpcClient() {{
setConfig(new XmlRpcClientConfigImpl() {{
setServerURL(new URL(String.format("%s/xmlrpc/2/object", url)));
}});
}};
models.execute("execute_kw", asList(

asList("read"),
new HashMap() {{ put("raise_exception", false); }}
));
.. code-block:: json

List records
------------
Records can be listed and filtered via :meth:`~openerp.models.Model.search`.
:meth:`~openerp.models.Model.search` takes a mandatory
:ref:`domain <reference/orm/domains>` filter (possibly empty), and returns the
database identifiers of all records matching the filter. To list customer
companies for instance:
.. container:: doc-aside

'res.partner', 'search', array(
array(array('is_company', '=', true),
array('customer', '=', true))));
.. code-block:: java

By default a search will return the ids of all records matching the
condition, which may be a huge number. ``offset`` and ``limit`` parameters are
available to only retrieve a subset of all matched records.

Count records
-------------
Rather than retrieve a possibly gigantic list of records and count them,
:meth:`~openerp.models.Model.search_count` can be used to retrieve
only the number of records matching the query. It takes the same
:ref:`domain <reference/orm/domains>` filter as
:meth:`~openerp.models.Model.search` and no other parameter.
.. container:: doc-aside

.. warning::
calling ``search`` then ``search_count`` (or the other way around) may not
yield coherent results if other users are using the server: stored data

Read records
------------
Record data is accessible via the :meth:`~openerp.models.Model.read` method,
which takes a list of ids (as returned by
:meth:`~openerp.models.Model.search`) and optionally a list of fields to
fetch. By default, it will fetch all the fields the current user can read,
which tends to be a huge amount.
.. container:: doc-aside

Listing record fields
---------------------
:meth:`~openerp.models.Model.fields_get` can be used to inspect
a model's fields and check which ones seem to be of interest.
Because it returns a large amount of meta-information (it is also used by client
programs) it should be filtered before printing, the most interesting items
for a human user are ``string`` (the field's label), ``help`` (a help text if
available) and ``type`` (to know which values to expect, or to send when
updating a record):

Search and read
---------------
Because it is a very common task, Odoo provides a
:meth:`~openerp.models.Model.search_read` shortcut which as its name notes is
equivalent to a :meth:`~openerp.models.Model.search` followed by a
:meth:`~openerp.models.Model.read`, but avoids having to perform two requests
and keep ids around.
Its arguments are similar to :meth:`~openerp.models.Model.search`'s, but it
can also take a list of ``fields`` (like :meth:`~openerp.models.Model.read`,
if that list is not provided it will fetch all fields of matched records):
.. container:: doc-aside

Create records
--------------
Records of a model are created using :meth:`~openerp.models.Model.create`. The
method will create a single record and return its database identifier.
:meth:`~openerp.models.Model.create` takes a mapping of fields to values, used
to initialize the record. For any field which has a default value and is not
set through the mapping argument, the default value will be used.

Update records
--------------
Records can be updated using :meth:`~openerp.models.Model.write`, it takes
a list of records to update and a mapping of updated fields to values similar
to :meth:`~openerp.models.Model.create`.
Multiple records can be updated simultanously, but they will all get the same
values for the fields being set. It is not currently possible to perform
"computed" updates (where the value being set depends on an existing value of
a record).

Inspection and introspection
----------------------------
.. todo:: ``get_external_id`` is kinda crap and may not return an id: it just
gets a random existing xid but won't generate one if there is no
xid currently associated with the record. And operating with xids
isn't exactly fun in RPC.
While we previously used :meth:`~openerp.models.Model.fields_get` to query a
model and have been using an arbitrary model from the start, Odoo stores
most model metadata inside a few meta-models which allow both querying the
system and altering models and fields (with some limitations) on the fly over
XML-RPC.
.. _reference/webservice/inspection/models:
``ir.model``
''''''''''''
Provides information about Odoo models via its various fields
``name``
a human-readable description of the model
``model``
the name of each model in the system
``state``
whether the model was generated in Python code (``base``) or by creating
an ``ir.model`` record (``manual``)
``field_id``
list of the model's fields through a :class:`~openerp.fields.One2many` to
:ref:`reference/webservice/inspection/fields`
``view_ids``
:class:`~openerp.fields.One2many` to the :ref:`reference/views` defined
for the model
``access_ids``
:class:`~openerp.fields.One2many` relation to the
:ref:`reference/security/acl` set on the model
``ir.model`` can be used to
* query the system for installed models (as a precondition to operations
on the model or to explore the system's content)
* get information about a specific model (generally by listing the fields
associated with it)
* create new models dynamically over RPC
.. warning::
* "custom" model names must start with ``x_``
* the ``state`` must be provided and ``manual``, otherwise the model will
not be loaded
* it is not possible to add new *methods* to a custom model, only fields
.. container:: doc-aside
a custom model will initially contain only the "built-in" fields available
on all models:

.. _reference/webservice/inspection/fields:
``ir.model.fields``
'''''''''''''''''''
Provides information about the fields of Odoo models and allows adding
custom fields without using Python code
``model_id``
:class:`~openerp.fields.Many2one` to
:ref:`reference/webservice/inspection/models` to which the field belongs
``name``
the field's technical name (used in ``read`` or ``write``)
``field_description``
the field's user-readable label (e.g. ``string`` in ``fields_get``)
``ttype``
the :ref:`type <reference/orm/fields>` of field to create
``state``
whether the field was created via Python code (``base``) or via
``ir.model.fields`` (``manual``)
``required``, ``readonly``, ``translate``
enables the corresponding flag on the field
``groups``
:ref:`field-level access control <reference/security/fields>`, a
:class:`~openerp.fields.Many2many` to ``res.groups``
``selection``, ``size``, ``on_delete``, ``relation``, ``relation_field``, ``domain``
type-specific properties and customizations, see :ref:`the fields
documentation <reference/orm/fields>` for details
Like custom models, only new fields created with ``state="manual"`` are
activated as actual fields on the model.
.. warning:: computed fields can not be added via ``ir.model.fields``, some
field meta-information (defaults, onchange) can not be set either

Workflow manipulations
----------------------
:ref:`reference/workflows` can be moved along by sending them *signals*.
Instead of using the top-level ``execute_kw``, signals are sent using
``exec_workflow``.
Signals are sent to a specific record, and possibly trigger a transition on
the workflow instance associated with the record.

Report printing
---------------
Available reports can be listed by searching the ``ir.actions.report.xml``
model, fields of interest being
``model``
the model on which the report applies, can be used to look for available
reports on a specific model
``name``
human-readable report name
``report_name``
the technical name of the report, used to print it
Reports can be printed over RPC with the following information:
* the name of the report (``report_name``)
* the ids of the records to include in the report
