Alternate solution for raising `JSONAPI::Exceptions::InvalidFieldValue` in `replace_fields`?

I'm currently using a callback before save to handle authorization.

module V1
  class BaseResource < JSONAPI::Resource
    # ...
    set_callback :save, :before, :authorize
    # ...
  end
end

I verify that authorization has been performed on each action in the ApplicationController:

class ApplicationController < JSONAPI::ResourceController
  # ...
  after_action :verify_policy_authorized, except: [:index]
  def verify_policy_authorized
    raise PolicyAuthorizationNotPerformedError unless policy_authorized?
  end
  # ...
end

Unfortunately, if an invalid value is submitted for an enum attribute the before save callback never happens because a JSONAPI::Exceptions::InvalidFieldValue is raised in _replace_fields. This causes verify_policy_authorized to not be called which raises the PolicyAuthorizationNotPerformedError.

I could obviously hack in a fix, but I wondered if this was a sign that a more general approach would be better. For example, should we provide a hook into exceptions raised and rescued which would allow the user of jsonapi-resources to handle things like bypassing policy authorization?

まず、_replace_fields と JSONAPI::Exceptions::InvalidFieldValue を通る enum 検証パスを追跡し、その後 V1::BaseResource の save callback と ApplicationController の verify_policy_authorized を確認してください。この issue は一般的な exception hook を提案していますが、hook の動作も具体的な完了テストも定義していません。
