associated_object_keys()

many_to_one associations can only have associated objects if none of the :keys options have a nil value.

dataset_need_primary_key?()

Whether the dataset needs a primary key to function, false for many_to_one associations.

eager_graph_lazy_dataset?()

primary_key()

The column(s) in the associated table that the key in the current table references (either a symbol or an array).

primary_keys()

The columns in the associated table that the key in the current table references (always an array).

reciprocal_array?()

True only if the reciprocal is a one_to_many association.

returns_array?()
