Module: Sequel::Model::Associations::InstanceMethods

Defined in:

lib/sequel/model/associations.rb

Overview

Instance methods used to implement the associations support.

Instance Method Summary

• #associations ⇒ Object

  The currently cached associations.

• #freeze ⇒ Object

  Freeze the associations cache when freezing the object.

• #pk_or_nil ⇒ Object

  Formally used internally by the associations code, like pk but doesn’t raise an Error if the model has no primary key.

• #set_values(hash) ⇒ Object

  Clear the associations cache when refreshing.

Instance Method Details

#associations ⇒ Object

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 1442

def associations
  @associations ||= {}
end

#freeze ⇒ Object

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 1449

def freeze
  associations.freeze
  super
end

#pk_or_nil ⇒ Object

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 1462

def pk_or_nil
  key = primary_key
  key.is_a?(Array) ? key.map{|k| @values[k]} : @values[key]
end

#set_values(hash) ⇒ Object

Clear the associations cache when refreshing

# File 'lib/sequel/model/associations.rb', line 1455

def set_values(hash)
  @associations.clear if @associations
  super
end
