The keys in the associated model‘s table related to this association
# File lib/sequel/model/associations.rb, line 354 354: def associated_object_keys 355: self[:keys] 356: 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 360 360: def can_have_associated_objects?(obj) 361: !self[:primary_keys].any?{|k| obj.send(k).nil?} 362: 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 366 366: def default_key 367: 368: "#{underscore(demodulize(self[:model].name))}_id" 369: end
The key to use for the key hash when eager loading
# File lib/sequel/model/associations.rb, line 371 371: def eager_loader_key 372: cached_fetch(:eager_loader_key){primary_key} 373: 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 376 376: def eager_loading_predicate_key 377: cached_fetch(:eager_loading_predicate_key){qualify_assoc(self[:key])} 378: end
The column in the current table that the key in the associated table references.
# File lib/sequel/model/associations.rb, line 382 382: def primary_key 383: self[:primary_key] 384: end
primary_key qualified by the current table
# File lib/sequel/model/associations.rb, line 387 387: def qualified_primary_key 388: cached_fetch(:qualified_primary_key){qualify_cur(primary_key)} 389: 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 393 393: def reciprocal_array? 394: false 395: end
Destroying one_to_many associated objects automatically deletes the foreign key.
# File lib/sequel/model/associations.rb, line 398 398: def remove_before_destroy? 399: false 400: 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 403 403: def remove_should_check_existing? 404: true 405: end
