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_excInvalidRequestErrorr2)r3rGr(r4rrrr2szObjectDeletedError.__init__r6rcCr7r8r9r<rrrr=r>zObjectDeletedError.__reduce__r?)rGrHr(r)r@rArrrrrFs  rFc@r)UnmappedColumnErrorz5Mapping operation was requested on an unknown column.NrrrrrrLrrLc@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".)rJrKr2r Zclsname_as_plain_name)r3rNrPrRrTrVrrrr2s$ z LoaderStrategyException.__init__N) rNrOrPrQrRrSrTrUrVrW)rrrrr2rrrrrMsrMrCrOr6strcCsPz d|j|jf}W|Sty't|dd}|dur$t|}Y|SY|Sw)N.r)joinrrAttributeErrorgetattrrepr)rCcls_namerrrr/s  r/r%r)c CsTtjj}z||j}Wnttftyi}Ynwt|}|s(d|dSdS)Nr*r+) r r,r-Zmanager_of_classmappersr0 TypeErrorNO_STATEr/)rCr4r_r5rrrrEs  rEN)rCrOr6rX)rCrOr6r)))r __future__rtypingrrrrrrr rJr r r Z interfacesrrrGrrr[KeyErrorraZSQLAlchemyErrorrZConcurrentModificationErrorrrKrr r!r$r0rFrLrMr/rBrErrrrsB                $ !
