Instance Method Details

#prepare_versioned_options(options) ⇒ Object

The prepare_versioned_options method has three purposes:

  1. Populate the provided options with default values where needed

  2. Prepare options for use with the has_many association

  3. Save user-configurable options in a class-level variable

Options are given priority in the following order:

  1. Those passed directly to the versioned method

  2. Those specified in an initializer configure block

  3. Default values specified in prepare_versioned_options

The method is overridden in feature modules that require specific options outside the standard has_many associations.
