Instance Method Details

#acts_as_approvable(options = {}) ⇒ Object

Declare this in your model to require approval on new records or changes to fields.

Parameters:

  • options (Hash) (defaults to: {}) —

    the options for this models approval workflow.

Options Hash (options):

  • :on (Symbol, Array) —

    The events to require approval on (‘:create` or `:update`).

  • :state_field (String) —

    The local field to store ‘:create` approval state.

  • :ignore (Array) —

    A list of fields to ignore. By default we ignore ‘:created_at`, `:updated_at` and the field specified in `:state_field`.

  • :only (Array) —

    A list of fields to explicitly require approval on. This list supercedes ‘:ignore`.
