- inline default execution occurs for *all* non-PK columns
unconditionally - preexecute only for non-executemany PK cols on
PG, Oracle, etc.
- new default docs
will add the given mapper/class or ColumnElement to the query at compile
time, and apply them to the instances method. the user is responsible
for constructing reasonable join conditions (otherwise you can get
full cartesian products). result set is the list of tuples, non-uniqued.
- fixed multi-mapper instances() to pad out shorter results with None so
zip() gets everything
that the class of object attached to a parent object is appropriate
(i.e. if A.items stores B objects, raise an error if a C is appended to A.items)
- new extension sqlalchemy.ext.associationproxy, provides transparent "association object"
mappings. new example examples/association/proxied_association.py illustrates.
- some example cleanup
