Database population
-------------------
Odoo CLI offers a :ref:`database population<reference/cmdline/populate>` feature.
.. code-block:: console
odoo-bin populate
Instead of the tedious manual, or programmatic, specification of test data,
one can use this feature to fill a database on demand with the desired number of test data.
This can be used to detect diverse bugs or performance issues in tested flows.
.. _reference/testing/populate/methods:
To specify this feature for a given model, the following methods and attributes can be defined.
.. currentmodule:: odoo.models
.. autoattribute:: Model._populate_sizes
.. autoattribute:: Model._populate_dependencies
.. automethod:: Model._populate
.. automethod:: Model._populate_factories
.. note::
You have to define at least :meth:`~odoo.models.Model._populate` or :meth:`~odoo.models.Model._populate_factories`
on the model to enable database population.
Example model
~~~~~~~~~~~~~
.. code-block:: python
from odoo.tools import populate
class CustomModel(models.Model)
_inherit = "custom.some_model"
_populate_sizes = {"small": 100, "medium": 2000, "large": 10000}
_populate_dependencies = ["custom.some_other_model"]
def _populate_factories(self):
# Record ids of previously populated models are accessible in the registry
some_other_ids = self.env.registry.populated_models["custom.some_other_model"]
def get_some_field(values=None, random=None, **kwargs):
""" Choose a value for some_field depending on other fields values.
:param dict values:
:param random: seeded :class:`random.Random` object
"""
field_1 = values['field_1']
if field_1 in [value2, value3]:
return random.choice(some_field_values)
return False
return [
("field_1", populate.randomize([value1, value2, value3])),
("field_2", populate.randomize([value_a, value_b], [0.5, 0.5])),
("some_other_id", populate.randomize(some_other_ids)),
("some_field", populate.compute(get_some_field, seed="some_field")),
('active', populate.cartesian([True, False])),
]
def _populate(self, size):
records = super()._populate(size)
# If you want to update the generated records
# E.g setting the parent-child relationships
records.do_something()
return records
Population tools
~~~~~~~~~~~~~~~~
Multiple population tools are available to easily create
the needed data generators.
