* - Fixed 1.0 regression where the "parent entity" of a synonym-Mike Bayer2015-06-271-1/+1
| | | | | | | | | | | | | mapped attribute on top of an :func:`.aliased` object would resolve to the original mapper, not the :func:`.aliased` version of it, thereby causing problems for a :class:`.Query` that relies on this attribute (e.g. it's the only representative attribute given in the constructor) to figure out the correct FROM clause for the query. fixes #3466 - apply consitency to ._parententity vs. __clause_element__()._annotations['parententity'] in terms of aliased class, test it all.
* - Fixed 1.0 regression where the enhanced behavior of single-inheritanceMike Bayer2015-06-191-3/+4
| | | | | | | | joins of :ticket:`3222` takes place inappropriately for a JOIN along explicit join criteria with a single-inheritance subclass that does not make use of any discriminator, resulting in an additional "AND NULL" clause. fixes #3462
* - Liberalized an assertion that was added as part of :ticket:`3347`Mike Bayer2015-05-021-1/+5
| | | | | | | | to protect against unknown conditions when splicing inner joins together within joined eager loads with ``innerjoin=True``; if some of the joins use a "secondary" table, the assertion needs to unwrap further joins in order to pass. fixes #3412
* - Fixed a critical regression caused by :ticket:`3061` where theMike Bayer2015-04-171-1/+1
| | | | | | | | | | | NEVER_SET symbol could easily leak into a lazyload query, subsequent to the flush of a pending object. This would occur typically for a many-to-one relationship that does not use a simple "get" strategy. The good news is that the fix improves efficiency vs. 0.9, because we can now skip the SELECT statement entirely when we detect NEVER_SET symbols present in the parameters; prior to :ticket:`3061`, we couldn't discern if the None here were set or not. fixes #3368

* - The :meth:`.PropComparator.of_type` modifier has beenMike Bayer2014-11-241-3/+19
| | | | | | | | | | | | | | | improved in conjunction with loader directives such as :func:`.joinedload` and :func:`.contains_eager` such that if two :meth:`.PropComparator.of_type` modifiers of the same base type/path are encountered, they will be joined together into a single "polymorphic" entity, rather than replacing the entity of type A with the one of type B. E.g. a joinedload of ``A.b.of_type(BSub1)->BSub1.c`` combined with joinedload of ``A.b.of_type(BSub2)->BSub2.c`` will create a single joinedload of ``A.b.of_type((BSub1, BSub2)) -> BSub1.c, BSub2.c``, without the need for the ``with_polymorphic`` to be explicit in the query. fixes #3256

|/ | | | | | | | | | :meth:`.Query.outerjoin`, or the standalone :func:`.orm.join` / :func:`.orm.outerjoin` functions to a single-inheritance subclass will now include the "single table criteria" in the ON clause even if the ON clause is otherwise hand-rolled; it is now added to the criteria using AND, the same way as if joining to a single-table target using relationship or similar. fixes #3222
* - remove some old cruftMike Bayer2014-09-071-3/+1
| | | | | | - prop.compare() isn't needed; replace with prop._with_parent() for relationships - update docs in orm/interfaces
* - rework ColumnAdapter and ORMAdapter to only provide the featuresticket_3148Mike Bayer2014-09-071-10/+8
| | | | | | | | | | | we're now using; rework them fully so that their behavioral contract is consistent regarding adapter.traverse() vs. adapter.columns[], add a full suite of tests including advanced wrapping scenarios previously only covered by test/orm/test_froms.py and test/orm/inheritance/test_relationships.py - identify several cases where label._order_by_label_clause would be corrupted, e.g. due to adaption or annotation separately - add full tests for #3148
* - enhance ClauseAdapter / ColumnAdapter to have new behaviors with labels.Mike Bayer2014-09-071-4/+7
| | | | | | | | | | | | | | | | | | | | | The "anonymize label" logic is now generalized to ClauseAdapter, and takes place when the anonymize_labels flag is sent, taking effect for all .columns lookups as well as within traverse() calls against the label directly. - traverse() will also memoize what it gets in columns, so that calling upon traverse() / .columns against the same Label will produce the same anonymized label. This is so that AliasedClass produces the same anonymized label when it is accessed per-column (e.g. SomeAlias.some_column) as well as when it is applied to a Query, and within column loader strategies (e.g. query(SomeAlias)); the former uses traverse() while the latter uses .columns - AliasedClass now calls onto ColumnAdapter - Query also makes sure to use that same ColumnAdapter from the AliasedClass in all cases - update the logic from 0.9 in #1068 to make use of the same _label_resolve_dict we use for #2992, simplifying how that works and adding support for new scenarios that were pretty broken (see #3148, #3188)

* - Related to :ticket:`3060`, an adjustment has been made to the unitMike Bayer2014-05-301-2/+1
| | | | | | | | | | of work such that loading for related many-to-one objects is slightly more aggressive, in the case of a graph of self-referential objects that are to be deleted; the load of related objects is to help determine the correct order for deletion if passive_deletes is not set. - revert the changes to test_delete_unloaded_m2o, these deletes do in fact need to occur in the order of the two child objects first.
* - Adjustment to attribute mechanics concerning when a value isMike Bayer2014-05-291-1/+2
| | | | | | | | | | | | | | implicitly initialized to None via first access; this action, which has always resulted in a population of the attribute, now emits an attribute event just like any other attribute set operation and generates the same kind of history as one. Additionally, many mapper internal operations will no longer implicitly generate these "None" values when various never-set attributes are checked. These are subtle behavioral fixes to attribute mechanics which provide a better solution to the problem of :ticket:`3060`, which also involves recognition of attributes explicitly set to ``None`` vs. attributes that were never set. fixes #3061

* - Some refinements to the :class:`.AliasedClass` construct with regardsMike Bayer2013-11-231-14/+6
| | | | | | | | | | | | | | | to descriptors, like hybrids, synonyms, composites, user-defined descriptors, etc. The attribute adaptation which goes on has been made more robust, such that if a descriptor returns another instrumented attribute, rather than a compound SQL expression element, the operation will still proceed. Addtionally, the "adapted" operator will retain its class; previously, a change in class from ``InstrumentedAttribute`` to ``QueryableAttribute`` (a superclass) would interact with Python's operator system such that an expression like ``aliased(MyClass.x) > MyClass.x`` would reverse itself to read ``myclass.x < myclass_1.x``. The adapted attribute will also refer to the new :class:`.AliasedClass` as its parent which was not always the case before. [ticket:2872]
