.. _preparing-values-for-use-in-database-lookups:

|

Preparing values for use in database lookups
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
As with value conversions, preparing a value for database lookups is a
|
||||
two phase process.
|
||||
|
||||
:meth:`.get_prep_lookup` performs the first phase of lookup preparation:
|
||||
type conversion and data validation.
|
||||
|
||||
Prepares the ``value`` for passing to the database when used in a lookup (a
|
||||
``WHERE`` constraint in SQL). The ``lookup_type`` parameter will be one of the
|
||||
valid Django filter lookups: ``exact``, ``iexact``, ``contains``, ``icontains``,
|
||||
``gt``, ``gte``, ``lt``, ``lte``, ``in``, ``startswith``, ``istartswith``,
|
||||
``endswith``, ``iendswith``, ``range``, ``year``, ``month``, ``day``,
|
||||
``isnull``, ``search``, ``regex``, and ``iregex``.
|
||||
|
||||
If you are using :doc:`custom lookups </howto/custom-lookups>`, the
|
||||
``lookup_type`` can be any ``lookup_name`` used by the project's custom lookups.
|
||||
|
||||
Your method must be prepared to handle all of these ``lookup_type`` values and
|
||||
should raise either a ``ValueError`` if the ``value`` is of the wrong sort (a
|
||||
list when you were expecting an object, for example) or a ``TypeError`` if
|
||||
your field does not support that type of lookup. For many fields, you can get
|
||||
by with handling the lookup types that need special handling for your field
|
||||
and pass the rest to the :meth:`~Field.get_db_prep_lookup` method of the parent
|
||||
class.
|
||||
|
||||
If you needed to implement :meth:`.get_db_prep_save`, you will usually need to
|
||||
implement :meth:`.get_prep_lookup`. If you don't, :meth:`.get_prep_value` will
|
||||
be called by the default implementation, to manage ``exact``, ``gt``, ``gte``,
|
||||
``lt``, ``lte``, ``in`` and ``range`` lookups.
|
||||
|
||||
You may also want to implement this method to limit the lookup types that could
|
||||
be used with your custom field type.
|
||||
|
||||
Note that, for ``"range"`` and ``"in"`` lookups, ``get_prep_lookup`` will receive
|
||||
a list of objects (presumably of the right type) and will need to convert them
|
||||
to a list of things of the right type for passing to the database. Most of the
|
||||
time, you can reuse ``get_prep_value()``, or at least factor out some common
|
||||
pieces.
|
||||
|
||||
For example, the following code implements ``get_prep_lookup`` to limit the
|
||||
accepted lookup types to ``exact`` and ``in``::
|
||||
|
||||
class HandField(models.Field):
|
||||
# ...
|
||||
|
||||
def get_prep_lookup(self, lookup_type, value):
|
||||
# We only handle 'exact' and 'in'. All others are errors.
|
||||
if lookup_type == 'exact':
|
||||
return self.get_prep_value(value)
|
||||
elif lookup_type == 'in':
|
||||
return [self.get_prep_value(v) for v in value]
|
||||
else:
|
||||
raise TypeError('Lookup type %r not supported.' % lookup_type)
|
||||
|
||||
For performing database-specific data conversions required by a lookup,
|
||||
you can override :meth:`~Field.get_db_prep_lookup`.

|

``Field`` is an abstract class that represents a database table column.
|
||||
Django uses fields to create the database table (:meth:`db_type`), to map
|
||||
Python types to database (:meth:`get_prep_value`) and vice-versa
|
||||
(:meth:`from_db_value`), and to apply :doc:`/ref/models/lookups`
|
||||
(:meth:`get_prep_lookup`).
|
||||
(:meth:`from_db_value`).
|
||||
|
||||
A field is thus a fundamental piece in different Django APIs, notably,
|
||||
:class:`models <django.db.models.Model>` and :class:`querysets
|
||||
|
@ -1847,26 +1846,6 @@ Field API reference
|

|
||||
See :ref:`preprocessing-values-before-saving` for usage.
|
||||
|
||||
When a lookup is used on a field, the value may need to be "prepared".
|
||||
Django exposes two methods for this:
|
||||
|
||||
.. method:: get_prep_lookup(lookup_type, value)
|
||||
|
||||
Prepares ``value`` to the database prior to be used in a lookup.
|
||||
The ``lookup_type`` will be the registered name of the lookup. For
|
||||
example: ``"exact"``, ``"iexact"``, or ``"contains"``.
|
||||
|
||||
See :ref:`preparing-values-for-use-in-database-lookups` for usage.
|
||||
|
||||
.. method:: get_db_prep_lookup(lookup_type, value, connection, prepared=False)
|
||||
|
||||
Similar to :meth:`get_db_prep_value`, but for performing a lookup.
|
||||
|
||||
As with :meth:`get_db_prep_value`, the specific connection that will
|
||||
be used for the query is passed as ``connection``. In addition,
|
||||
``prepared`` describes whether the value has already been prepared with
|
||||
:meth:`get_prep_lookup`.
|
||||
|
||||
Fields often receive their values as a different type, either from
|
||||
serialization or from forms.
