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%Nc[RRnU(dSURU5-n[R R X5 g)NzDInstance '%s' has been deleted, or its row is otherwise not present.)rr'r( state_strsa_excInvalidRequestErrorr/)r0stater2r3s rr/ObjectDeletedError.__init__sF~~&&026..2GH  ""++D6rc<URSURS44$r7r9r<s rr=ObjectDeletedError.__reduce__r?rr r@rAr rrrKrKos,& ./ 70 74rrKc\rSrSrSrSrg)UnmappedColumnErrorz5Mapping operation was requested on an unknown column.r Nr r rrrVrVs?rrVc\rSrSrSrSrSrg)LoaderStrategyExceptionz2A loader strategy for an attribute does not exist.c 6Uc)[RRUSU<SU<35 g[RRUS[R"U5<SU<S[R"U5<S[R"U5<S3 5 g)NzCan't find strategy z for z Can't apply "z" strategy to property "z", which is a "z7"; this loader strategy is intended to be used with a "z".)rOrPr/rclsname_as_plain_name)r0applied_to_property_typerequesting_property applies_toactual_strategy_type strategy_keys rr/ LoaderStrategyException.__init__s{ '  & & / /!46   & & / / ../CD'../GH..z: rr N)r r rrrr/rr rrrYrYs <rrYcSRURUR45nU$![a [ USS5nUc [ U5nU$f=f)N.r )joinr r AttributeErrorgetattrrepr)rFcls_names rr+r+s]!88S^^S\\:; O !3 D1  CyH O !s'+%AAr%c[RRnURU5Rn[U5nU(dSU-$g![ 4[ -a 0nN.f=f)NzClass '%s' is not mapped)rr'r(manager_of_classmappers TypeErrorNO_STATEr+)rFr3rlr4s rr-r-sh >> " "D'',44 # D )D00  <( "sAA&%A&N)rrrOrrrrfKeyErrorrnSQLAlchemyErrorrConcurrentModificationErrorrrPrrrr#r,rKrVrYr+rBr-r rrrss!& H %LV++2-;'';JF..Jf44F224M4< 4 4!433!4H@&44@f88@*+ 1, 1r
