Conditions which cause this to happen include: * A flush may have attempted to update or delete rows and an unexpected number of rows were matched during the UPDATE or DELETE statement. Note that when version_id_col is used, rows in UPDATE or DELETE statements are also matched against the current known version identifier. * A mapped object with version_id_col was refreshed, and the version number coming back from the database does not match that of the object itself. * A object is detached from its parent object, however the object was previously attached to a different parent identity which was garbage collected, and a decision cannot be made if the new parent was really the most recent "parent".

A refresh operation proceeds when an expired attribute is accessed on an object, or when :meth:`_query.Query.get` is used to retrieve an object which is, upon retrieval, detected as expired. A SELECT is emitted for the target row based on primary key; if no row is returned, this exception is raised. The true meaning of this exception is simply that no row exists for the primary key identifier associated with a persistent object. The row may have been deleted, or in some cases the primary key updated to a new value, outside of the ORM's management of the target object. r, Nc � � t j j }|sd|j |� z }t j j | |� y )NzDInstance '%s' has been deleted, or its row is otherwise not present.)r r0 r1 � state_str�sa_exc�InvalidRequestErrorr7 )r8 �stater: r; s r r7 zObjectDeletedError.__init__� sH � ��~�~�&�&���0�26�.�.��2G�H� � �"�"�+�+�D�#�6r c �< � | j d | j d ffS r> r? rB s r rC z ObjectDeletedError.__reduce__� rD r rE )rW zInstanceState[Any]r: rG rH rJ r r r rR rR � s. � ��& �T���.�/� 7� 0� 7�4r rR c � � e Zd ZdZy)�UnmappedColumnErrorz5Mapping operation was requested on an unknown column.Nr r r r rZ rZ � s � �?r rZ c �, � e Zd ZdZ dd�Zy)�LoaderStrategyExceptionz2A loader strategy for an attribute does not exist.c � � |�'t j j | d|�d|��� y |�J �t j j | dt j |� �d|�dt |� �dt |� �d� � y )NzCan't find strategy z for z Can't apply "z" strategy to property "z", which is a "z7"; this loader strategy is intended to be used with a "z".)rU rV r7 r �clsname_as_plain_namer )r8 �applied_to_property_type�requesting_property� applies_to�actual_strategy_type� strategy_keys r r7 z LoaderStrategyException.__init__� s{ � � � '� � &� &� /� /�� �!4�6� � �)� )�)� � &� &� /� /�� �.�.�/C�D�'�2�3K�L�2�:�>�� r N) r_ � Type[Any]r` zMapperProperty[Any]ra z#Optional[Type[MapperProperty[Any]]]rb z Optional[Type[LoaderStrategy]]rc zTuple[Any, ...])r r r r r7 r r r r\ r\ � s: � �<��"+�� 1�� 8� � =� � &� r r\ c � � dj | j | j f� }|S # t $ r t | dd � }|� t | � }Y |S w xY w)N�.r )�joinr r �AttributeError�getattr�repr)rO �cls_names r r4 r4 � s] � �!��8�8�S�^�^�S�\�\� :�;�� �O�� � !��3� �D�1�� � ��C�y�H�� �O� !�s �'+ �#A�Ar, c �� � t j j } |j | � j }t | � }|sd|� d�S y # t t ft z $ r i }Y �.w xY w)Nr. r/ ) r r0 r1 �manager_of_class�mappersr5 � TypeError�NO_STATEr4 )rO r; rn r< s r rN rN � sw � � �>�>� "� "�D���'�'��,�4�4�� �#� �D� ����o�.�.��� �� � � � � �� �s �A � A&�%A&N)rO rd rI �str)rO rd rI rG )*r � __future__r �typingr r r r r r r r � r rU r r � interfacesr r rW r r rh �KeyErrorrp �SQLAlchemyErrorr �ConcurrentModificationErrorr! rV r# r% r' r+ r5 rR rZ r\ r4 rK rN r r r �<module>ry s0 �� !� "� � � � � � � 0� � � &� ��*�*�$� �T�� �� �H� %�� L��V�+�+� �2 -� �;��'�'� ;�J�F�.�.� J��f� 4� 4� ��F� 2� 2� �4�M� 4�< 4� � 4�!4��3�3� !4�H@�&�4�4� @� �f� 8� 8� �B� ����*�+�� ,�r
