Method: Sequel::Model::DatasetMethods#as_hash

Defined in:
lib/sequel/model/base.rb

#as_hash(key_column = nil, value_column = nil, opts = OPTS) ⇒ Object

This allows you to call as_hash without any arguments, which will result in a hash with the primary key value being the key and the model object being the value.

Artist.dataset.as_hash # SELECT * FROM artists
# => {1=>#<Artist {:id=>1, ...}>,
#     2=>#<Artist {:id=>2, ...}>,
#     ...}
