The :class:`_orm.Mapper` object is instantiated using the :func:`~sqlalchemy.orm.mapper` function. For information about instantiating new :class:`_orm.Mapper` objects, see that function's documentation. When :func:`.mapper` is used explicitly to link a user defined class with table metadata, this is referred to as *classical mapping*. Modern SQLAlchemy usage tends to favor the :mod:`sqlalchemy.ext.declarative` extension for class configuration, which makes usage of :func:`.mapper` behind the scenes. Given a particular class known to be mapped by the ORM, the :class:`_orm.Mapper` which maintains it can be acquired using the :func:`_sa.inspect` function:: from sqlalchemy import inspect mapper = inspect(MyClass) A class which was mapped by the :mod:`sqlalchemy.ext.declarative` extension will also have its mapper available via the ``__mapper__`` attribute. F)z0.7z:class:`.MapperExtension` is deprecated in favor of the :class:`.MapperEvents` listener interface. The :paramref:`.mapper.extension` parameter will be removed in a future release.)z1.1zThe :paramref:`.mapper.order_by` parameter is deprecated, and will be removed in a future release. Use :meth:`_query.Query.order_by` to determine the ordering of a result set.)1.3aThe :paramref:`.mapper.non_primary` parameter is deprecated, and will be removed in a future release. The functionality of non primary mappers is now better suited using the :class:`.AliasedClass` construct, which can also be used as the target of a :func:`_orm.relationship` in 1.3.) extensionorder_by non_primaryNTdcTtj|td|_d|_tj||_||_| durtj| |_n| |_| |_ t| tr| |_ d|_ n| |_ | durd|_n| d|_n| |_||_d|_||_||_||_||_|pi|_g|_||_||_||_t5j||_g|_tj|_||_ ||_!||_"d|_#d|_$d|_%i|_&||_'d|_(tj| pg|_)||_*|jr|jsd|_+n||_+t|jt4j,rt[j.d|/|||_0||_1|i|_2n||_2|tj3||_4nd|_4|rtj3||_5nd|_5d|_6tn8 |j9j:;|||<|=|>|?|@|A|Bdt_D|Ed|FtnGdS#tnGwxYw)aNReturn a new :class:`_orm.Mapper` object. This function is typically used behind the scenes via the Declarative extension. When using Declarative, many of the usual :func:`.mapper` arguments are handled by the Declarative extension itself, including ``class_``, ``local_table``, ``properties``, and ``inherits``. Other options are passed to :func:`.mapper` using the ``__mapper_args__`` class variable:: class MyClass(Base): __tablename__ = 'my_table' id = Column(Integer, primary_key=True) type = Column(String(50)) alt = Column("some_alt", Integer) __mapper_args__ = { 'polymorphic_on' : type } Explicit use of :func:`.mapper` is often referred to as *classical mapping*. The above declarative example is equivalent in classical form to:: my_table = Table("my_table", metadata, Column('id', Integer, primary_key=True), Column('type', String(50)), Column("some_alt", Integer) ) class MyClass(object): pass mapper(MyClass, my_table, polymorphic_on=my_table.c.type, properties={ 'alt':my_table.c.some_alt }) .. seealso:: :ref:`classical_mapping` - discussion of direct usage of :func:`.mapper` :param class\_: The class to be mapped. When using Declarative, this argument is automatically passed as the declared class itself. :param local_table: The :class:`_schema.Table` or other selectable to which the class is mapped. May be ``None`` if this mapper inherits from another mapper using single-table inheritance. When using Declarative, this argument is automatically passed by the extension, based on what is configured via the ``__table__`` argument or via the :class:`_schema.Table` produced as a result of the ``__tablename__`` and :class:`_schema.Column` arguments present. :param always_refresh: If True, all query operations for this mapped class will overwrite all data within object instances that already exist within the session, erasing any in-memory changes with whatever information was loaded from the database. Usage of this flag is highly discouraged; as an alternative, see the method :meth:`_query.Query.populate_existing`. :param allow_partial_pks: Defaults to True. Indicates that a composite primary key with some NULL values should be considered as possibly existing within the database. This affects whether a mapper will assign an incoming row to an existing identity, as well as if :meth:`.Session.merge` will check the database first for a particular primary key value. A "partial primary key" can occur if one has mapped to an OUTER JOIN, for example. :param batch: Defaults to ``True``, indicating that save operations of multiple entities can be batched together for efficiency. Setting to False indicates that an instance will be fully saved before saving the next instance. This is used in the extremely rare case that a :class:`.MapperEvents` listener requires being called in between individual row persistence operations. :param column_prefix: A string which will be prepended to the mapped attribute name when :class:`_schema.Column` objects are automatically assigned as attributes to the mapped class. Does not affect explicitly specified column-based properties. See the section :ref:`column_prefix` for an example. :param concrete: If True, indicates this mapper should use concrete table inheritance with its parent mapper. See the section :ref:`concrete_inheritance` for an example. :param confirm_deleted_rows: defaults to True; when a DELETE occurs of one more rows based on specific primary keys, a warning is emitted when the number of rows matched does not equal the number of rows expected. This parameter may be set to False to handle the case where database ON DELETE CASCADE rules may be deleting some of those rows automatically. The warning may be changed to an exception in a future release. .. versionadded:: 0.9.4 - added :paramref:`.mapper.confirm_deleted_rows` as well as conditional matched row checking on delete. :param eager_defaults: if True, the ORM will immediately fetch the value of server-generated default values after an INSERT or UPDATE, rather than leaving them as expired to be fetched on next access. This can be used for event schemes where the server-generated values are needed immediately before the flush completes. By default, this scheme will emit an individual ``SELECT`` statement per row inserted or updated, which note can add significant performance overhead. However, if the target database supports :term:`RETURNING`, the default values will be returned inline with the INSERT or UPDATE statement, which can greatly enhance performance for an application that needs frequent access to just-generated server defaults. .. seealso:: :ref:`orm_server_defaults` .. versionchanged:: 0.9.0 The ``eager_defaults`` option can now make use of :term:`RETURNING` for backends which support it. :param exclude_properties: A list or set of string column names to be excluded from mapping. See :ref:`include_exclude_cols` for an example. :param extension: A :class:`.MapperExtension` instance or list of :class:`.MapperExtension` instances which will be applied to all operations by this :class:`_orm.Mapper`. :param include_properties: An inclusive list or set of string column names to map. See :ref:`include_exclude_cols` for an example. :param inherits: A mapped class or the corresponding :class:`_orm.Mapper` of one indicating a superclass to which this :class:`_orm.Mapper` should *inherit* from. The mapped class here must be a subclass of the other mapper's class. When using Declarative, this argument is passed automatically as a result of the natural class hierarchy of the declared classes. .. seealso:: :ref:`inheritance_toplevel` :param inherit_condition: For joined table inheritance, a SQL expression which will define how the two tables are joined; defaults to a natural join between the two tables. :param inherit_foreign_keys: When ``inherit_condition`` is used and the columns present are missing a :class:`_schema.ForeignKey` configuration, this parameter can be used to specify which columns are "foreign". In most cases can be left as ``None``. :param legacy_is_orphan: Boolean, defaults to ``False``. When ``True``, specifies that "legacy" orphan consideration is to be applied to objects mapped by this mapper, which means that a pending (that is, not persistent) object is auto-expunged from an owning :class:`.Session` only when it is de-associated from *all* parents that specify a ``delete-orphan`` cascade towards this mapper. The new default behavior is that the object is auto-expunged when it is de-associated with *any* of its parents that specify ``delete-orphan`` cascade. This behavior is more consistent with that of a persistent object, and allows behavior to be consistent in more scenarios independently of whether or not an orphan object has been flushed yet or not. See the change note and example at :ref:`legacy_is_orphan_addition` for more detail on this change. :param non_primary: Specify that this :class:`_orm.Mapper` is in addition to the "primary" mapper, that is, the one used for persistence. The :class:`_orm.Mapper` created here may be used for ad-hoc mapping of the class to an alternate selectable, for loading only. :paramref:`_orm.Mapper.non_primary` is not an often used option, but is useful in some specific :func:`_orm.relationship` cases. .. seealso:: :ref:`relationship_non_primary_mapper` :param order_by: A single :class:`_schema.Column` or list of :class:`_schema.Column` objects for which selection operations should use as the default ordering for entities. By default mappers have no pre-defined ordering. :param passive_deletes: Indicates DELETE behavior of foreign key columns when a joined-table inheritance entity is being deleted. Defaults to ``False`` for a base mapper; for an inheriting mapper, defaults to ``False`` unless the value is set to ``True`` on the superclass mapper. When ``True``, it is assumed that ON DELETE CASCADE is configured on the foreign key relationships that link this mapper's table to its superclass table, so that when the unit of work attempts to delete the entity, it need only emit a DELETE statement for the superclass table, and not this table. When ``False``, a DELETE statement is emitted for this mapper's table individually. If the primary key attributes local to this table are unloaded, then a SELECT must be emitted in order to validate these attributes; note that the primary key columns of a joined-table subclass are not part of the "primary key" of the object as a whole. Note that a value of ``True`` is **always** forced onto the subclass mappers; that is, it's not possible for a superclass to specify passive_deletes without this taking effect for all subclass mappers. .. versionadded:: 1.1 .. seealso:: :ref:`passive_deletes` - description of similar feature as used with :func:`_orm.relationship` :paramref:`.mapper.passive_updates` - supporting ON UPDATE CASCADE for joined-table inheritance mappers :param passive_updates: Indicates UPDATE behavior of foreign key columns when a primary key column changes on a joined-table inheritance mapping. Defaults to ``True``. When True, it is assumed that ON UPDATE CASCADE is configured on the foreign key in the database, and that the database will handle propagation of an UPDATE from a source column to dependent columns on joined-table rows. When False, it is assumed that the database does not enforce referential integrity and will not be issuing its own CASCADE operation for an update. The unit of work process will emit an UPDATE statement for the dependent columns during a primary key change. .. seealso:: :ref:`passive_updates` - description of a similar feature as used with :func:`_orm.relationship` :paramref:`.mapper.passive_deletes` - supporting ON DELETE CASCADE for joined-table inheritance mappers :param polymorphic_load: Specifies "polymorphic loading" behavior for a subclass in an inheritance hierarchy (joined and single table inheritance only). Valid values are: * "'inline'" - specifies this class should be part of the "with_polymorphic" mappers, e.g. its columns will be included in a SELECT query against the base. * "'selectin'" - specifies that when instances of this class are loaded, an additional SELECT will be emitted to retrieve the columns specific to this subclass. The SELECT uses IN to fetch multiple subclasses at once. .. versionadded:: 1.2 .. seealso:: :ref:`with_polymorphic_mapper_config` :ref:`polymorphic_selectin` :param polymorphic_on: Specifies the column, attribute, or SQL expression used to determine the target class for an incoming row, when inheriting classes are present. This value is commonly a :class:`_schema.Column` object that's present in the mapped :class:`_schema.Table`:: class Employee(Base): __tablename__ = 'employee' id = Column(Integer, primary_key=True) discriminator = Column(String(50)) __mapper_args__ = { "polymorphic_on":discriminator, "polymorphic_identity":"employee" } It may also be specified as a SQL expression, as in this example where we use the :func:`.case` construct to provide a conditional approach:: class Employee(Base): __tablename__ = 'employee' id = Column(Integer, primary_key=True) discriminator = Column(String(50)) __mapper_args__ = { "polymorphic_on":case([ (discriminator == "EN", "engineer"), (discriminator == "MA", "manager"), ], else_="employee"), "polymorphic_identity":"employee" } It may also refer to any attribute configured with :func:`.column_property`, or to the string name of one:: class Employee(Base): __tablename__ = 'employee' id = Column(Integer, primary_key=True) discriminator = Column(String(50)) employee_type = column_property( case([ (discriminator == "EN", "engineer"), (discriminator == "MA", "manager"), ], else_="employee") ) __mapper_args__ = { "polymorphic_on":employee_type, "polymorphic_identity":"employee" } When setting ``polymorphic_on`` to reference an attribute or expression that's not present in the locally mapped :class:`_schema.Table`, yet the value of the discriminator should be persisted to the database, the value of the discriminator is not automatically set on new instances; this must be handled by the user, either through manual means or via event listeners. A typical approach to establishing such a listener looks like:: from sqlalchemy import event from sqlalchemy.orm import object_mapper @event.listens_for(Employee, "init", propagate=True) def set_identity(instance, *arg, **kw): mapper = object_mapper(instance) instance.discriminator = mapper.polymorphic_identity Where above, we assign the value of ``polymorphic_identity`` for the mapped class to the ``discriminator`` attribute, thus persisting the value to the ``discriminator`` column in the database. .. warning:: Currently, **only one discriminator column may be set**, typically on the base-most class in the hierarchy. "Cascading" polymorphic columns are not yet supported. .. seealso:: :ref:`inheritance_toplevel` :param polymorphic_identity: Specifies the value which identifies this particular class as returned by the column expression referred to by the ``polymorphic_on`` setting. As rows are received, the value corresponding to the ``polymorphic_on`` column expression is compared to this value, indicating which subclass should be used for the newly reconstructed object. :param properties: A dictionary mapping the string names of object attributes to :class:`.MapperProperty` instances, which define the persistence behavior of that attribute. Note that :class:`_schema.Column` objects present in the mapped :class:`_schema.Table` are automatically placed into ``ColumnProperty`` instances upon mapping, unless overridden. When using Declarative, this argument is passed automatically, based on all those :class:`.MapperProperty` instances declared in the declared class body. :param primary_key: A list of :class:`_schema.Column` objects which define the primary key to be used against this mapper's selectable unit. This is normally simply the primary key of the ``local_table``, but can be overridden here. :param version_id_col: A :class:`_schema.Column` that will be used to keep a running version id of rows in the table. This is used to detect concurrent updates or the presence of stale data in a flush. The methodology is to detect if an UPDATE statement does not match the last known version id, a :class:`~sqlalchemy.orm.exc.StaleDataError` exception is thrown. By default, the column must be of :class:`.Integer` type, unless ``version_id_generator`` specifies an alternative version generator. .. seealso:: :ref:`mapper_version_counter` - discussion of version counting and rationale. :param version_id_generator: Define how new version ids should be generated. Defaults to ``None``, which indicates that a simple integer counting scheme be employed. To provide a custom versioning scheme, provide a callable function of the form:: def generate_version(version): return next_version Alternatively, server-side versioning functions such as triggers, or programmatic versioning schemes outside of the version id generator may be used, by specifying the value ``False``. Please see :ref:`server_side_version_counter` for a discussion of important points when using this option. .. versionadded:: 0.9.0 ``version_id_generator`` supports server-side version number generation. .. seealso:: :ref:`custom_version_counter` :ref:`server_side_version_counter` :param with_polymorphic: A tuple in the form ``(, )`` indicating the default style of "polymorphic" loading, that is, which tables are queried at once. is any single or list of mappers and/or classes indicating the inherited classes that should be loaded at once. The special value ``'*'`` may be used to indicate all descending classes should be loaded immediately. The second tuple argument indicates a selectable that will be used to query for multiple classes. .. seealso:: :ref:`with_polymorphic` - discussion of polymorphic querying techniques. class_NFc|pddzS)Nrr)xs i/builddir/build/BUILD/cloudlinux-venv-1.0.12/venv/lib64/python3.11/site-packages/sqlalchemy/orm/mapper.pyz!Mapper.__init__..s16Q,When mapping against a select() construct, map against an alias() of the construct instead.This because several databases don't allow a SELECT from a subquery that does not have an alias.T constructed)Hr assert_arg_typetyper) class_managerto_list_primary_key_argumentr&r%always_refresh isinstancerversion_id_propversion_id_colversion_id_generatorconcretesingleinherits local_tableinherit_conditioninherit_foreign_keys_init_properties_delete_orphansbatcheager_defaults column_prefixr_clause_element_as_exprpolymorphic_on_dependency_processors immutabledict validatorspassive_updatespassive_deleteslegacy_is_orphan_clause_adapter_requires_row_aliasing_inherits_equated_pairs_memoized_values_compiled_cache_size_reconstructor_deprecated_extensionsallow_partial_pksconfirm_deleted_rows SelectBasesa_excInvalidRequestError_set_with_polymorphicpolymorphic_loadpolymorphic_identitypolymorphic_mapto_setinclude_propertiesexclude_properties configured_CONFIGURE_MUTEXacquiredispatch_events_new_mapper_instance_configure_inheritance"_configure_legacy_instrument_class _configure_class_instrumentation_configure_listeners_configure_properties_configure_polymorphic_setter_configure_pksr" _new_mappers_log_expire_memoizationsrelease)selfr)r?r primary_keyr&r>r@rAr$r%r7r:r;rH_polymorphic_mapr]r<with_polymorphicr\rVrDrFr`rarLrMrWrErNrSs r-__init__zMapper.__init__ks|*64BB !%)\+%>%>"& 5  L22DMM$DM, nn 5 5 1#1D "&D  "0D  5 ( ((-D % % ! )(>(>D % %( > ,F  ""#3444 0 %9!  ##%D #3D  )&*k2D&E&ED # #&*D #  +&*k2D&E&ED # #&*D #   """ ' M ! 6 6vt D D D  ' ' ) ) )  3 3 5 5 5  1 1 3 3 3  % % ' ' '  & & ( ( (  . . 0 0 0    ! ! !"&F  IIm $ $ $  % % ' ' '  $ $ & & & & &  $ $ & & & &s C!N N'c|S)zr8r3r issubclassr)rY ArgumentError__name__r&r?rr=r<iterate_to_rootrHrPr@sql_utiljoin_conditionrjoinr_rAcriterion_as_pairsonclauserQr]_identity_classr:r;warn descriptionr%r^rDappend base_mapperrLrM _all_tablesr\_add_with_polymorphic_subclassset)rsnprzfkss r-rhzMapper._configure_inheritances $(#4#6#6 =~ /$-..

This is an object that provides each property based on its key name. For instance, the mapper for a ``User`` class which has ``User.name`` attribute would provide ``mapper.attrs.name``, which would be the :class:`.ColumnProperty` representing the ``name`` column. The namespace object can also be iterated, which would yield each :class:`.MapperProperty`. :class:`_orm.Mapper` has several pre-filtered views of this attribute which limit the types of properties returned, including :attr:`.synonyms`, :attr:`.column_attrs`, :attr:`.relationships`, and :attr:`.composites`. .. warning:: The :attr:`_orm.Mapper.attrs` accessor namespace is an instance of :class:`.OrderedProperties`. This is a dictionary-like object which includes a small number of named methods such as :meth:`.OrderedProperties.items` and :meth:`.OrderedProperties.values`. When accessing attributes dynamically, favor using the dict-access scheme, e.g. ``mapper.attrs[somename]`` over ``getattr(mapper.attrs, somename)`` to avoid name collisions. .. seealso:: :attr:`_orm.Mapper.all_orm_descriptors` )r"rorr ImmutablePropertiesrrys r-attrsz Mapper.attrs, s/D      ' 444r/crtjt|jS)ay A namespace of all :class:`.InspectionAttr` attributes associated with the mapped class. These attributes are in all cases Python :term:`descriptors` associated with the mapped class or its superclasses. This namespace includes attributes that are mapped to the class as well as attributes declared by extension modules. It includes any Python descriptor type that inherits from :class:`.InspectionAttr`. This includes :class:`.QueryableAttribute`, as well as extension types such as :class:`.hybrid_property`, :class:`.hybrid_method` and :class:`.AssociationProxy`. To distinguish between mapped attributes and extension attributes, the attribute :attr:`.InspectionAttr.extension_type` will refer to a constant that distinguishes between different extension types. The sorting of the attributes is based on the following rules: 1. Iterate through the class and its superclasses in order from subclass to superclass (i.e. iterate through ``cls.__mro__``) 2. For each class, yield the attributes in the order in which they appear in ``__dict__``, with the exception of those in step 3 below. In Python 3.6 and above this ordering will be the same as that of the class' construction, with the exception of attributes that were added after the fact by the application or the mapper. 3. If a certain attribute key is also in the superclass ``__dict__``, then it's included in the iteration for that class, and not the class in which it first appeared. The above process produces an ordering that is deterministic in terms of the order in which attributes were assigned to the class. .. versionchanged:: 1.3.19 ensured deterministic ordering for :meth:`_orm.Mapper.all_orm_descriptors`. When dealing with a :class:`.QueryableAttribute`, the :attr:`.QueryableAttribute.property` attribute refers to the :class:`.MapperProperty` property, which is what you get when referring to the collection of mapped properties via :attr:`_orm.Mapper.attrs`. .. warning:: The :attr:`_orm.Mapper.all_orm_descriptors` accessor namespace is an instance of :class:`.OrderedProperties`.
