The AssociationReflection subclass for many_to_pg_array associations.
# File lib/sequel/plugins/pg_array_associations.rb, line 80 def array_type cached_fetch(:array_type) do if (sch = associated_class.db_schema) && (s = sch[self[:key]]) && (t = s[:db_type]) t else :integer end end end
The array column in the associated model containing foreign keys to the current model.
# File lib/sequel/plugins/pg_array_associations.rb, line 92 def associated_object_keys [self[:key]] end
many_to_pg_array associations can have associated objects as long as they have a primary key.
# File lib/sequel/plugins/pg_array_associations.rb, line 98 def can_have_associated_objects?(obj) obj.get_column_value(self[:primary_key]) end
Assume that the key in the associated table uses a version of the current model’s name suffixed with _ids.
# File lib/sequel/plugins/pg_array_associations.rb, line 104 def default_key :"#{underscore(demodulize(self[:model].name))}_ids" end
Always use the ruby eager_graph limit strategy if association is limited.

Always use the ruby eager limit strategy

Handle silent failure of add/remove methods if raise_on_save_failure is false.

The hash key to use for the eager loading predicate (left side of IN (1, 2, 3))
# File lib/sequel/plugins/pg_array_associations.rb, line 138 def predicate_key cached_fetch(:predicate_key){qualify_assoc(self[:key_column])} end
The column in the current table that the keys in the array column in the associated table reference.

Destroying the associated object automatically removes the association, since the association is stored in the associated object.
