Sequel 5.91.0 Released

[jeremyevans]

Sequel 5.91.0 has been released!

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.
