The keys in the associated model‘s table related to this association
# File lib/sequel/model/associations.rb, line 377 377: def associated_object_keys 378: self[:keys] 379: 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 383 383: def can_have_associated_objects?(obj) 384: !self[:primary_keys].any?{|k| obj.send(k).nil?} 385: 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 389 389: def default_key 390: 391: "#{underscore(demodulize(self[:model].name))}_id" 392: 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 394 394: def predicate_key 395: cached_fetch(:predicate_key){qualify_assoc(self[:key])} 396: end
The column in the current table that the key in the associated table references.
# File lib/sequel/model/associations.rb, line 400 400: def primary_key 401: self[:primary_key] 402: end
primary_key qualified by the current table
# File lib/sequel/model/associations.rb, line 405 405: def qualified_primary_key 406: cached_fetch(:qualified_primary_key){qualify_cur(primary_key)} 407: 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 411 411: def reciprocal_array? 412: false 413: end
Destroying one_to_many associated objects automatically deletes the foreign key.
# File lib/sequel/model/associations.rb, line 416 416: def remove_before_destroy? 417: false 418: 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 421 421: def remove_should_check_existing? 422: true 423: end
