Methods

Public Instance methods

The keys in the associated model‘s table related to this association

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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))

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 436
436:         def primary_key
437:           self[:primary_key]
438:         end
qualified_key()

Alias for predicate_key

primary_key qualified by the current table

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 457
457:         def remove_should_check_existing?
458:           true
459:         end

One to many associations set the reciprocal to self when loading associated records.

[Source]

     # File lib/sequel/model/associations.rb, line 462
462:         def set_reciprocal_to_self?
463:           true
464:         end
