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.Nctjj}|sd|j|z}tj j ||y)NzDInstance '%s' has been deleted, or its row is otherwise not present.)rr2r3 state_strsa_excInvalidRequestErrorr9)r:stater<r=s rr9zObjectDeletedError.__init__sH~~&&026..2GH  ""++D#6rc<|jd|jdffSr@rArDs rrEzObjectDeletedError.__reduce__rFrrG)rYzInstanceState[Any]r<rIrJrLrrrrTrTs.&T./ 70 74rrTceZdZdZy)UnmappedColumnErrorz5Mapping operation was requested on an unknown column.Nrrrrr\r\s?rr\c,eZdZdZ ddZy)LoaderStrategyExceptionz2A loader strategy for an attribute does not exist.c |'tjj|d|d|y|Jtjj|dtj|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".)rWrXr9rclsname_as_plain_namer )r:applied_to_property_typerequesting_property applies_toactual_strategy_type strategy_keys rr9z LoaderStrategyException.__init__s{ '  & & / /!46  ) ))  & & / / ../CD'23KL2:> rN) ra Type[Any]rbzMapperProperty[Any]rcz#Optional[Type[MapperProperty[Any]]]rdzOptional[Type[LoaderStrategy]]rezTuple[Any, ...])rrrrr9rrrr^r^s:<"+18  =  & rr^c dj|j|jf}|S#t$rt |dd}| t |}Y|SwxYw)N.r)joinrrAttributeErrorgetattrrepr)rQcls_names rr6r6s]!88S^^S\\:; O !3 D1  CyH O !s'+#AAr.ctjj} |j|j}t|}|sd|dSy#t t ftz$ri}Y.wxYw)Nr0r1) rr2r3manager_of_classmappersr7 TypeErrorNO_STATEr6)rQr=rpr>s rrPrPsw >> " "D'',44 # D o..     sA A&%A&N)rQrfrKstr)rQrfrKrI),r __future__rtypingrrrrrr rr r rWrr interfacesrrrYrrrjKeyErrorrrSQLAlchemyErrorrConcurrentModificationErrorr!
