This allows sessions that rely upon either customized :meth:`.Session.get_bind` schemes or "bound" metadata to work in all relevant cases. fixes #3227 fixes #3242 fixes #1326

* | - The "wildcard" loader options, in particular the one set up byMike Bayer2015-01-134-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | the :func:`.orm.load_only` option to cover all attributes not explicitly mentioned, now takes into account the superclasses of a given entity, if that entity is mapped with inheritance mapping, so that attribute names within the superclasses are also omitted from the load. Additionally, the polymorphic discriminator column is unconditionally included in the list, just in the same way that primary key columns are, so that even with load_only() set up, polymorphic loading of subtypes continues to function correctly. fixes #3287

| | | | | | | | | | | | | | | | | | | | :class:`.Query` before it fetched results, particularly when row processors can't be formed, the cursor would stay open with results pending and not actually be closed. This is typically only an issue on an interpreter like Pypy where the cursor isn't immediately GC'ed, and can in some circumstances lead to transactions/ locks being open longer than is desirable. fixes #3285

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | non-recommended use case of replacing a relationship on a fixed mapped class many times, referring to an arbitrarily growing number of target mappers. A warning is emitted when the old relationship is replaced, however if the mapping were already used for querying, the old relationship would still be referenced within some registries. fixes #3251

| * | - Fixed bug in single table inheritance where a chain of joinsMike Bayer2014-10-231-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that included the same single inh entity more than once (normally this should raise an error) could, in some cases depending on what was being joined "from", implicitly alias the second case of the single inh entity, producing a query that "worked". But as this implicit aliasing is not intended in the case of single table inheritance, it didn't really "work" fully and was very misleading, since it wouldn't always appear. fixes #3233

| | | | | | | | | | | | | | | | | | | | | and :meth:`.Query.outerjoin` to a single-inheritance subclass using ``of_type()`` would not render the "single table criteria" in the ON clause if the ``from_joinpoint=True`` flag were set. fixes #3232

| | | | | | | | | | | | | | | | | | | | | | | | | | | | already have more than one ForeignKeyConstraint referring to them. This limits the check to what we hope is the most common case, but we benefit that the memory and config-time impact is scaled back dramatically.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ultimately will populate a foreign key column in conflict with another, where the relationships are attempting to copy values from different source columns. This occurs in the case where composite foreign keys with overlapping columns are mapped to relationships that each refer to a different referenced column. A new documentation section illustrates the example as well as how to overcome the issue by specifying "foreign" columns specifically on a per-relationship basis. fixes #3230

Previously, string names were taken in directly and passed to the core update statement without any means to resolve against the mapped entity. Support for synonyms and hybrid attributes as the subject attributes of :meth:`.Query.update` are also supported. fixes #3228
