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# NzInstanceState[Any]r% )�stater' c C s, t jj}|sd|�|� }tj�| |� d S )NzDInstance '%s' has been deleted, or its row is otherwise not present.)r r* r+ Z state_str�sa_exc�InvalidRequestErrorr0 )r1 rA r' r2 r r r r0 � s ��zObjectDeletedError.__init__r r4 c C s | j d | jd ffS r6 r7 r: r r r r; � s z ObjectDeletedError.__reduce__)Nr< r r r r r@ � s r@ c @ s e Zd ZdZdS )�UnmappedColumnErrorz5Mapping operation was requested on an unknown column.Nr r r r r rD � s rD c @ s& e Zd ZdZdddddd�dd �Zd S ) �LoaderStrategyExceptionz2A loader strategy for an attribute does not exist.� Type[Any]zMapperProperty[Any]z#Optional[Type[MapperProperty[Any]]]z Optional[Type[LoaderStrategy]]zTuple[Any, ...])�applied_to_property_type�requesting_property� applies_to�actual_strategy_type� strategy_keyc C sX |d kr t j�| d||f � n4|d k s,t�t j�| dt�|�|t|�t|�f � d S )Nz Can't find strategy %s for %szuCan't apply "%s" strategy to property "%s", which is a "%s"; this loader strategy is intended to be used with a "%s".)rB rC r0 �AssertionErrorr Zclsname_as_plain_namer )r1 rG rH rI rJ rK r r r r0 � s$ �� ���z LoaderStrategyException.__init__N)r r r r r0 r r r r rE � s rE rF �str)r> r5 c C sL zd� | j| jf�}W n0 tk rF t| dd �}|d krBt| �}Y nX |S )N�.r )�joinr r �AttributeError�getattr�repr)r> �cls_namer r r r- � s r- r# r% c C sZ t jj}z|�| �j}W n ttft k r8 i }Y nX t| �}|sRd|� d�S d S d S )Nr( r) ) r r* r+ Zmanager_of_class�mappersr. � TypeError�NO_STATEr- )r> r2 rT r3 r r r r? � s �� r?
