Write a much better section about server defaults

2018-08-09T17:40:31+00:00

Include information about eager_defaults etc.  These
docs were written before we had all the features
we do now.

- add a new FAQ recipe for "walk all objects", replacing the need

to use mapper.cascade_iterator() for this purpose as it was not really
designed for that use case.  Add docs to cascade_iterator() pointing
to the recipe.  fixes #3498

if the name of the attribute being accessed is non-specific,
thereby avoiding collisions on names like items, values, keys.

- The "wildcard" loader options, in particular the one set up by

2015-01-13T22:09:16+00:00

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

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.
