The keys in the associated model‘s table related to this association
# File lib/sequel/model/associations.rb, line 306 306: def associated_object_keys 307: self[:keys] 308: 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 312 312: def can_have_associated_objects?(obj) 313: !self[:primary_keys].any?{|k| obj.send(k).nil?} 314: 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 318 318: def default_key 319: 320: "#{underscore(demodulize(self[:model].name))}_id" 321: end
The key to use for the key hash when eager loading
# File lib/sequel/model/associations.rb, line 323 323: def eager_loader_key 324: self[:eager_loader_key] ||= primary_key 325: 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 328 328: def eager_loading_predicate_key 329: self[:eager_loading_predicate_key] ||= qualify_assoc(self[:key]) 330: end
The column in the current table that the key in the associated table references.
# File lib/sequel/model/associations.rb, line 334 334: def primary_key 335: self[:primary_key] 336: end
primary_key qualified by the current table
# File lib/sequel/model/associations.rb, line 339 339: def qualified_primary_key 340: self[:qualified_primary_key] ||= qualify_cur(primary_key) 341: 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 345 345: def reciprocal_array? 346: false 347: end
Destroying one_to_many associated objects automatically deletes the foreign key.
# File lib/sequel/model/associations.rb, line 350 350: def remove_before_destroy? 351: false 352: 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 355 355: def remove_should_check_existing? 356: true 357: end
