The array column in the associated model containing foreign keys to the current model.
# File lib/sequel/plugins/pg_array_associations.rb, line 90 90: def associated_object_keys 91: [self[:key]] 92: 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 96 96: def can_have_associated_objects?(obj) 97: obj.get_column_value(self[:primary_key]) 98: 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 102 102: def default_key 103: 104: "#{underscore(demodulize(self[:model].name))}_ids" 105: end
Always use the ruby eager_graph limit strategy if association is limited.

Always use the ruby eager limit strategy

Don‘t use a filter by associations 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 129 129: def predicate_key 130: cached_fetch(:predicate_key){qualify_assoc(self[:key_column])} 131: end
The column in the current table that the keys in the array column in the associated table reference.
