Instance Method Details

#unwrap_columns_for(active_record_model, attribute: true, **options) ⇒ Object

Sets delegate methods via ::unwrap_for en masse for all columns. The :attribute keyword argument can specify which columns are attributes in one of three ways from different values:

  • true: all columns will be considered attributes

  • false: no columns will be considered attributes

  • A hash with the key :only, whose value specifies which columns to consider as attributes, either singular or as an array of column names.

  • A hash with the key :except, whose value specifies which columns to consider as attributes, either singular or as an array of column names.
