Update to make "changed" attribute only present on the parent class

2014-10-21T19:25:27+00:00

Changed attribute will now only be created on the parent class in case inheritance was used.

- Reversing a change that was made in 0.9, the "singleton" nature

2014-10-19T22:26:14+00:00

of the "constants" :func:`.null`, :func:`.true`, and :func:`.false`
has been reverted.   These functions returning a "singleton" object
had the effect that different instances would be treated as the
same regardless of lexical use, which in particular would impact
the rendering of the columns clause of a SELECT statement.
fixes #3170

- Fixed bug where :meth:`.Session.expunge` would not fully detach

2014-10-19T20:53:45+00:00

the given object if the object had been subject to a delete
operation that was flushed, but not committed.  This would also
affect related operations like :func:`.make_transient`.
fixes #3139

- control the module name of the exception here for py3k compat

2014-10-19T17:37:48+00:00

- for #3230, scale back the check to only look at columns that

2014-10-19T10:43:53+00:00

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.

- A warning is emitted in the case of multiple relationships that

2014-10-19T04:01:50+00:00

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.

- Exception messages have been spiffed up a bit. The SQL statement

2014-10-17T23:37:45+00:00

and parameters are not displayed if None, reducing confusion for
error messages that weren't related to a statement.  The full
module and classname for the DBAPI-level exception is displayed,
making it clear that this is a wrapped DBAPI exception.  The
statement and parameters themselves are bounded within a bracketed
sections to better isolate them from the error message and from
each other.

- The :meth:`.Query.update` method will now convert string key

2014-10-16T18:36:56+00:00

names in the given dictionary of values into mapped attribute names
against the mapped class being updated.  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.
