Sequel::Model::Associations::InstanceMethods

Instance methods used to implement the associations support.

Public Instance Methods

associations() click to toggle source

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() click to toggle source

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
pk_or_nil() click to toggle source

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
set_values(hash) click to toggle source

Clear the associations cache when refreshing

# File lib/sequel/model/associations.rb, line 1496
def set_values(hash)
  @associations.clear if @associations
  super
end
