Instance methods used to implement the associations support.
The currently cached associations. A hash with the keys being the association name symbols and the values being the associated object or nil (many_to_one), or the array of associated objects (*_to_many).
# File lib/sequel/model/associations.rb, line 1483 def associations @associations ||= {} end
Freeze the associations cache when freezing the object. Note that retrieving associations after freezing will still work in most cases, but the associations will not be cached in the association cache.
# File lib/sequel/model/associations.rb, line 1490 def freeze associations.freeze super end
Formally used internally by the associations code, like pk but doesn't raise an Error if the model has no primary key. Not used any longer, deprecated.
# File lib/sequel/model/associations.rb, line 1503 def pk_or_nil Sequel::Deprecation.deprecate('Model#pk_or_nil', 'There is no replacement') key = primary_key key.is_a?(Array) ? key.map{|k| @values[k]} : @values[key] end
