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]r)r*cCs,tjj}|s d||}tj||dS)NzDInstance '%s' has been deleted, or its row is otherwise not present.)r r-r. state_strsa_excInvalidRequestErrorr4)r5rIr)r6rrrr4szObjectDeletedError.__init__r8rcCr9r:r;r>rrrr?r@zObjectDeletedError.__reduce__rA)rIrJr)r*rBrCrrrrrHs  rHc@r)UnmappedColumnErrorz5Mapping operation was requested on an unknown column.NrrrrrrNrrNc@seZdZdZdd d ZdS)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 Cs^|durtj|d||fdS|dusJtj|dt||t|t|fdS)NzCan'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".)rLrMr4r clsname_as_plain_name)r5rPrRrTrVrXrrrr4s$ z LoaderStrategyException.__init__N) rPrQrRrSrTrUrVrWrXrY)rrrrr4rrrrrOsrOrErQr8strcCsPz d|j|jf}W|Sty't|dd}|dur$t|}Y|SY|Sw)N.r)joinrrAttributeErrorgetattrrepr)rEcls_namerrrr1s  r1r&r*c CsTtjj}z||j}Wnttftyi}Ynwt|}|s(d|dSdS)Nr+r,) r r-r.manager_of_classmappersr2 TypeErrorNO_STATEr1)rEr6rcr7rrrrGs  rGN)rErQr8r[)rErQr8r*))r __future__rtypingrrrrrrr rLr r r interfacesrrrIrrr^KeyErrorreSQLAlchemyErrorrConcurrentModificationErrorrrMrr r!r%r2rHrNrOr1rDrGrrrrsB                $ !
