composite_primary_keys: association.build for has_many should populate newly built child record with owner's PK values
The FK attributes in the new record used to be set by set_belongs_to_association_for
(which the composite_primary_keys was overriding to work with CPK in its AR 3.0 series),
until this change in ActiveRecord:

date_field helper for HTML5 type="date" inputs! And a version of value_before_type_cast that returns a string in ISO-8601 format as the value for Dates, as specified by http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#date-state-(type=date)
# Extensions to gems/actionpack-3.2.13/lib/action_view/helpers/form_helper.rb
=begin
A version of InstanceTag.value_before_type_cast that returns a string in ISO-8601 format for Date columns.
The original behavior of value_before_type_cast was to return the Date object itself. But the default to_s on a Date returns a string like "June 5, 2013".
However, HTML5 date input fields expect their values to be in ISO-8601 format ("2013-06-05") and won't recognize the value if it is in some other format.
This makes it so you can simply do this:

Change all datetime columns to have a precision of 0, to match the default precision of these columns in MySQL. This is useful if you migrate a database from MySQL to PostgreSQL and don't need the extra microsecond precision (precision: 6) that is the default in PostgreSQL (see http://www.postgresql.org/docs/9.2/static/datatype-datetime.html).
