  # For example, you may want to send an email after a foo is updated.

  # end

  # Override this method to specify custom lookup behavior.

  # actions.

  # def find_resource(param)
  #   Foo.find_by!(slug: param)
  # end

  # The result of this lookup will be available as `requested_resource`

  # Override this if you have certain roles that require a subset
  # this will be used to set the records shown on the `index` action.

  # data before it's persisted. For example, the following would turn all
  # empty values into nil values. It uses other APIs such as `resource_class`
  # and `dashboard`:
  #
  # def resource_params
  #   params.require(resource_class.model_name.param_key).
  #     permit(dashboard.permitted_attributes).
  #     transform_values { |value| value == "" ? nil : value }
