Methods

Public Instance methods

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

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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))

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 400
400:         def primary_key
401:          self[:primary_key]
402:         end
qualified_key()

Alias for predicate_key

primary_key qualified by the current table

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 421
421:         def remove_should_check_existing?
422:           true
423:         end

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

[Source]

     # File lib/sequel/model/associations.rb, line 426
426:         def set_reciprocal_to_self?
427:           true
428:         end
