- links to a new record created from the provided values
- ``(1, id, values: dict)``
- updates the already-linked record of id ``id`` with the

- unlinks the linked record of id ``id`` without deleting it
- ``(4, id, _)``
- links to an existing record of id ``id``
- ``(5, _, _)``
- unlinks all records in the relation, equivalent to using
- the command ``3`` on every linked record
- ``(6, _, ids)``
- replaces the existing list of linked records by the provoded
- ones, equivalent to using ``5`` then ``4`` for each id in
- ``ids``)
-
- (in command triplets, ``_`` values are ignored and can be
- anything, generally ``0`` or ``False``)
-
- Any command can be used on :class:`~openerp.fields.Many2many`,

- :class:`~openerp.fields.One2many`.

+ * For :class:`~openerp.fields.Boolean`, the value should be a

+ * For :class:`~openerp.fields.Selection`, the value should match the
+ selection values (generally :class:`python:str`, sometimes
+ :class:`python:int`)
+ * For :class:`~openerp.fields.Many2one`, the value should be the

+ This format is a list of triplets executed sequentially, where each
+ triplet is a command to execute on the set of records. Not all
+ commands apply in all situations. Possible commands are:
+
+ ``(0, _, values)``
+ adds a new record created from the provided ``value`` dict.
+ ``(1, id, values)``
+ updates an existing record of id ``id`` with the values in
+ ``values``. Can not be used in :meth:`~.create`.
+ ``(2, id, _)``
+ removes the record of id ``id`` from the set, then deletes it
+ (from the database). Can not be used in :meth:`~.create`.
+ ``(3, id, _)``
+ removes the record of id ``id`` from the set, but does not
+ delete it. Can not be used on
+ :class:`~openerp.fields.One2many`. Can not be used in
+ :meth:`~.create`.
+ ``(4, id, _)``
+ adds an existing record of id ``id`` to the set. Can not be

+ ``(5, _, _)``
+ removes all records from the set, equivalent to using the
+ command ``3`` on every record explicitly. Can not be used on
+ :class:`~openerp.fields.One2many`. Can not be used in
+ :meth:`~.create`.
+ ``(6, _, ids)``
+ replaces all existing records in the set by the ``ids`` list,
