Methods

Public Instance methods

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

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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

[Source]

     # 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))

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 382
382:         def primary_key
383:          self[:primary_key]
384:         end
qualified_key()

primary_key qualified by the current table

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # 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.

[Source]

     # File lib/sequel/model/associations.rb, line 403
403:         def remove_should_check_existing?
404:           true
405:         end

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

[Source]

     # File lib/sequel/model/associations.rb, line 408
408:         def set_reciprocal_to_self?
409:           true
410:         end
