any kind of schema/mapping construct from a
declarative mixin, including columns with foreign
keys, relationships, column_property, deferred.
This solves all such issues on declarative mixins.
An error is raised if any MapperProperty subclass
is specified on a mixin without using @classproperty.

- un-anglicized the declarative docs
loading available, the new names for eagerload() and
eagerload_all() are joinedload() and joinedload_all(). The
old names will remain as synonyms for the foreseeable future.
- The "lazy" flag on the relationship() function now accepts
a string argument for all kinds of loading: "select", "joined",
"subquery", "noload" and "dynamic", where the default is now
"select". The old values of True/
False/None still retain their usual meanings and will remain
as synonyms for the foreseeable future.
- Added documentation to tutorial,mapper doc, api docs
for subqueryload, subqueryload_all, and other options.
relationship(), to eliminate confusion over the relational
algebra term. relation() however will remain available
in equal capacity for the foreseeable future. [ticket:1740]
- cleaned up tutorial w.r.t. eagerload, added a section for contains_eager as this function
is equally important
- added better linkages in sqlalchemy.orm reference documentation, updated antiquated
docs for contains_eager(), got aliased()/AliasedClass documented as well as Sphinx will
allow us
sqlalchemy.orm.attributes. Given an object, attribute name,
and value, will set the value on the object as part of its
"committed" state, i.e. state that is understood to have
been loaded from the database. Helps with the creation of
homegrown collection loaders and such.
- documented public attributes helper functions.
table of their own (i.e. use single table inheritance).
The columns will be appended to the base table, but only
mapped by the subclass.
- For both joined and single inheriting subclasses, the subclass
will only map those columns which are already mapped on the
superclass and those explicit on the subclass. Other
columns that are present on the `Table` will be excluded
from the mapping by default, which can be disabled
by passing a blank `exclude_properties` collection to the
`__mapper_args__`. This is so that single-inheriting
classes which define their own columns are the only classes
to map those columns. The effect is actually a more organized
mapping than you'd normally get with explicit `mapper()`
calls unless you set up the `exclude_properties` arguments
explicitly.
- docs/tests
- Documentation has been converted to Sphinx.
In particular, the generated API documentation
has been constructed into a full blown
"API Reference" section which organizes
editorial documentation combined with
generated docstrings. Cross linking between
sections and API docs are vastly improved,
a javascript-powered search feature is
provided, and a full index of all
classes, functions and members is provided.
