= New Features
* A pg_auto_validate_enums plugin has been added, for automatically
validating enum values on PostgreSQL:
class Person < Sequel::Model
# assume state enum column with allowed values active and inactive
plugin :pg_auto_validate_enums
end
p = Person.new(state: "active").valid? # => true
p = Person.new(state: "inactive").valid? # => true
p = Person.new(state: "other").valid? # => false
* The pg_auto_parameterize_in_array extension now supports a
:treat_string_list_as_untyped_array Database option. When using
this option, the array is not casted to a specific type:
DB[:table].where(enum_column: ["a", "b"])
SELECT * FROM table WHERE enum_column = ANY($1)
The pg_auto_parameterize_in_array extension also now avoids
Database#typecast_value calls at runtime, moving them to load time,
which speeds up the extension.
* The forbid_lazy_load plugin now supports an :allow_by_default plugin
option, which does not automatically forbid lazy loading when
retrieving multiple model instances. With this option, lazy
loading can still be forbidding explicitly on a per-object basis.
This can make it easier to gradually update code to support the
plugin.
= Other Improvements
* The pg_auto_constraint_validations plugin now sorts subhashes before
saving the cache file, resulting in more deterministic behavior.
* datetime(N) database types are once again recognized as :datetime.
This was broken in 5.32.0, when support for timestamp(N) with time
zone was added.
* AssociationReflection#hash has been added, to avoid the default
behavior that iterated over the entire AssociationReflection. This
can prevent a potential concurrency issue at runtime, and it also
makes the method faster.
* It is now possible to override nested_attributes behavior for
creating new objects by overriding Model#nested_attributes_new. You
can use this to support nested attributes for models using the
class_table_inheritance plugin.
= Backwards Compatibility
* Database options to configure the pg_auto_parameterize_in_array
extension must now be set before loading the extension. Setting
the options after loading the extension no longer has an effect.
