Fixed the persistent_to_deleted event

2016-09-29T22:59:34+00:00

Got a reference of the deleted instance before remove it from state.
The old code always send a None instead the instance.

- improve documentation for SessionTransaction re: parent

2016-09-24T04:49:22+00:00

and nested attributes and what these mean
- improve linking for after_transaction_create() / after_transaction_end()
events
- add public .parent attribute to detect top-level transaction within
these events

Ensure mapper.polymorphic_on is polymorphic_prop.columns[0]

2016-09-21T21:57:38+00:00

Fixed bug where joined eager loading would fail for a polymorphically-
loaded mapper, where the polymorphic_on was set to an un-mapped
expression such as a CASE expression.

Merge "Add the "triggering mapper" to the configure_mappers error message."

2016-09-20T17:58:55+00:00

Add the "triggering mapper" to the configure_mappers error message.

2016-09-20T16:11:11+00:00

There are cases where the originating mapper name is not
present in the exception message, such as relationship initialization
against an unmapped class.   Ensure the originating mapper is named
in the string output.

Merge "Allow SQL expressions to be set on PK columns"

Merge "Support bindparam() with callable for primaryjoin"

Allow SQL expressions to be set on PK columns

2016-09-20T15:33:16+00:00

Removes an unnecessary transfer of modified PK column
value to the params dictionary, so that if the modified PK column
is already present in value_params, this remains in effect.  Also
propagate a new flag through to _emit_update_statements() that will
trip "return_defaults()" across the board if a PK col w/ SQL expression
change is present, and pull this PK value in _postfetch as well assuming
we're an UPDATE.

Fixes: #3801

Support bindparam() with callable for primaryjoin

2016-09-19T20:22:08+00:00

Fixes the comparison of bindparam() objects based on
the "callable" parameter being present which helps to correctly
detect use_get, and also checks for "callable" when detecting
parameters for value substitution and will not impact the
object if present.
