= New Features
* An update_refresh plugin has been added, for refreshing a model
instance when updating. The default behavior is to only refresh
when inserting. However, if you have triggers on the model's table,
it's a good idea to refresh when updating to pick up the possibly
changed values. On databases that support UPDATE RETURNING, such as
PostgreSQL, the update and refresh are done in a single query.
* A delay_add_association plugin has been added, for delaying add_*
method calls for associations until after the receiver has been
saved, if the receiver is a new object. Example:
artist = Artist.new(:name=>'Foo')
artist.add_album(Album.new(:name=>'Bar'))
# No database queries yet
artist.save # Saves artist, then album
* A validate_associated plugin has been added, for validating
associated objects when validating the current object. This
was extracted from the nested_attributes plugin, and is also
used by the delay_add_association plugin. For example,
if you have an albums association and you want to validate all
associated objects before saving the current object, you can
cal validate_associated_object for each object:
def validate
super
reflection = association_reflection(:albums)
associations[:albums].each do |obj|
validate_associated_object(reflection, obj)
end
end
= Other Improvements
* Database#transaction now returns the block return value if
:rollback=>:always is used. Previously, it would return nil in
that case.
* Postgres::JSONBOp#[] and #get_text now return JSONBOp instances
instead of JSONOp instances.
* Model#move_to, #move_up, and #move_down in the list plugin now
automatically handle out-of-range targets by defaulting to the first
or last position in the list. Previously, using an out of range
target would raise an exception.
* Database#add_named_conversion_proc on PostgreSQL now works for enum
types.
* dataset.call_sproc(:insert, ...) now works correctly on JDBC.
* postgresql:// connection strings are now supported, since that is
the protocol name supported by libpq.
* Sequel has switched from rspec to minitest/spec for testing, and
now uses random test order when testing. During the conversion
process, many test order dependency bugs were fixed.
= Backwards Compatibility
* The deprecated fdbsql, jdbc/fdbsql, and openbase adapters have been
removed.
