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.NstateInstanceState[Any]r1r2ctjj}|sd||z}tj||dS)NzDInstance '%s' has been deleted, or its row is otherwise not present.)rr6r7 state_strsa_excInvalidRequestErrorr=)r>rVr1r?s rr=zObjectDeletedError.__init__sT~& 026..2G2GH  "++D#66666rrArc.|jd|jdffSrCrDrGs rrHzObjectDeletedError.__reduce__rIrrJ)rVrWr1r2rKrLrrrrUrUsf&T.// 7 7 7 70/ 7444444rrUceZdZdZdS)UnmappedColumnErrorz5Mapping operation was requested on an unknown column.Nrrrrr^r^s????rr^ceZdZdZdd Zd S)LoaderStrategyExceptionz2A loader strategy for an attribute does not exist.applied_to_property_type Type[Any]requesting_propertyMapperProperty[Any] applies_to#Optional[Type[MapperProperty[Any]]]actual_strategy_typeOptional[Type[LoaderStrategy]] strategy_keyTuple[Any, ...]c |(tj|d|d|dS|Jtj|dtj|d|dt |dt |d dS)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".)rZr[r=rclsname_as_plain_namer )r>rarcrergris rr=z LoaderStrategyException.__init__s '  & / /<>>>     rN) rarbrcrdrerfrgrhrirj)rrrrr=rrrr`r`s.<<rr`rOrbrAstrc d|j|jf}n2#t$r%t |dd}|t |}YnwxYw|S)N.r)joinrrAttributeErrorgetattrrepr)rOcls_names rr:r:si!88S^S\:;; !!!3 D11  CyyH!
