Fix the docstring of AppenerQuery.append() (#9336)

consider column.name directly when evaluating use_existing_column

2023-02-18T14:11:36+00:00

Fixed issue where new :paramref:`_orm.mapped_column.use_existing_column`
feature would not work if the two same-named columns were mapped under
attribute names that were differently-named from the explicit name given to
the column itself. The attribute names can now be differently named when
using this parameter.

Allow custom sorting of column in the ORM.

2023-02-17T00:21:43+00:00

To accommodate a change in column ordering used by ORM Declarative in
SQLAlchemy 2.0, a new parameter :paramref:`_orm.mapped_column.sort_order`
has been added that can be used to control the order of the columns defined
in the table by the ORM, for common use cases such as mixins with primary
key columns that should appear first in tables. The change notes at
:ref:`change_9297` illustrate the default change in ordering behavior
(which is part of all SQLAlchemy 2.0 releases) as well as use of the
:paramref:`_orm.mapped_column.sort_order` to control column ordering when
using mixins and multiple classes (new in 2.0.4).

immediateload lazy relationships named in refresh.attribute_names

2023-02-16T00:09:18+00:00

The :meth:`_orm.Session.refresh` method will now immediately load a
relationship-bound attribute that is explicitly named within the
:paramref:`_orm.Session.refresh.attribute_names` collection even if it is
currently linked to the "select" loader, which normally is a "lazy" loader
that does not fire off during a refresh. The "lazy loader" strategy will
now detect that the operation is specifically a user-initiated
:meth:`_orm.Session.refresh` operation which named this attribute
explicitly, and will then call upon the "immediateload" strategy to
actually emit SQL to load the attribute. This should be helpful in
particular for some asyncio situations where the loading of an unloaded
lazy-loaded attribute must be forced, without using the actual lazy-loading
attribute pattern not supported in asyncio.

add dataclasses callable and apply annotations more strictly

2023-02-16T00:09:14+00:00

Added new parameter ``dataclasses_callable`` to both the
:class:`_orm.MappedAsDataclass` class as well as the
:meth:`_orm.registry.mapped_as_dataclass` method which allows an
alternative callable to Python ``dataclasses.dataclass`` to be used in
order to produce dataclasses. The use case here is to drop in Pydantic's
dataclass function instead. Adjustments have been made to the mixin support
added for :ticket:`9179` in version 2.0.1 so that the ``__annotations__``
collection of the mixin is rewritten to not include the
:class:`_orm.Mapped` container, in the same way as occurs with mapped
classes, so that the Pydantic dataclasses constructor is not exposed to
unknown types.

rename EvaluatorCompiler to _EvaluatorCompiler

This is a private class, mark as such as some users
may have used this class directly in end-user code.
