Methods

Public Instance methods

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

[Source]

     # File lib/sequel/model/associations.rb, line 242
242:         def associated_object_keys
243:           self[:keys]
244:         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 248
248:         def can_have_associated_objects?(obj)
249:           !self[:primary_keys].any?{|k| obj.send(k).nil?}
250:         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 254
254:         def default_key
255: 
256:           "#{underscore(demodulize(self[:model].name))}_id"
257:         end

The key to use for the key hash when eager loading

[Source]

     # File lib/sequel/model/associations.rb, line 259
259:         def eager_loader_key
260:           self[:eager_loader_key] ||= primary_key
261:         end

The column in the current table that the key in the associated table references.

[Source]

     # File lib/sequel/model/associations.rb, line 264
264:         def primary_key
265:          self[:primary_key] ||= self[:model].primary_key
266:         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 270
270:         def reciprocal_array?
271:           false
272:         end

Destroying one_to_many associated objects automatically deletes the foreign key.

[Source]

     # File lib/sequel/model/associations.rb, line 275
275:         def remove_before_destroy?
276:           false
277:         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 280
280:         def remove_should_check_existing?
281:           true
282:         end

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

[Source]

     # File lib/sequel/model/associations.rb, line 285
285:         def set_reciprocal_to_self?
286:           true
287:         end
