The keys in the associated model‘s table related to this association
# File lib/sequel/model/associations.rb, line 413 413: def associated_object_keys 414: self[:keys] 415: end
one_to_many associations can only have associated objects if none of the :keys options have a nil value.
# File lib/sequel/model/associations.rb, line 419 419: def can_have_associated_objects?(obj) 420: !self[:primary_keys].any?{|k| obj.send(k).nil?} 421: end
Default foreign key name symbol for key in associated table that points to current table‘s primary key.
# File lib/sequel/model/associations.rb, line 425 425: def default_key 426: 427: "#{underscore(demodulize(self[:model].name))}_id" 428: end
The hash key to use for the eager loading predicate (left side of IN (1, 2, 3))
# File lib/sequel/model/associations.rb, line 430 430: def predicate_key 431: cached_fetch(:predicate_key){qualify_assoc(self[:key])} 432: end
The column in the current table that the key in the associated table references.
# File lib/sequel/model/associations.rb, line 436 436: def primary_key 437: self[:primary_key] 438: end
primary_key qualified by the current table
# File lib/sequel/model/associations.rb, line 441 441: def qualified_primary_key 442: cached_fetch(:qualified_primary_key){qualify_cur(primary_key)} 443: end
Whether the reciprocal of this association returns an array of objects instead of a single object, false for a one_to_many association.
# File lib/sequel/model/associations.rb, line 447 447: def reciprocal_array? 448: false 449: end
Destroying one_to_many associated objects automatically deletes the foreign key.
# File lib/sequel/model/associations.rb, line 452 452: def remove_before_destroy? 453: false 454: end
The one_to_many association needs to check that an object to be removed already is associated.
# File lib/sequel/model/associations.rb, line 457 457: def remove_should_check_existing? 458: true 459: end
