The keys in the associated model‘s table related to this association
# 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.
# 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.
# 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
# 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.
# 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.
# 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.
# 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.
# File lib/sequel/model/associations.rb, line 280 280: def remove_should_check_existing? 281: true 282: end
