Sequel::Model is an object relational mapper built on top of
Sequel core. Each model class is backed by a
dataset instance, and many dataset methods can be called directly on the
class. Model datasets return rows as model
instances, which are wrappers around the underlying hash that allow easily
updating or deleting the individual row.
Sequel::Model is built completely out of plugins. Plugins can override any class, instance, or
dataset method defined by a previous plugin and call super to get the
default behavior. By default, Sequel::Model loads two
plugins, Sequel::Model (which is itself a plugin) for the base
support, and Sequel::Model::Associations for the associations
support.
You can set the SEQUEL_NO_ASSOCIATIONS constant or environment
variable to make Sequel not load the
associations plugin by default.
