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?

首先沿着 _replace_fields 和 JSONAPI::Exceptions::InvalidFieldValue 跟踪 enum 验证路径，然后检查 V1::BaseResource 中的保存回调以及 ApplicationController 中的 verify_policy_authorized。该 issue 提议了一个通用的 exception hook，但没有定义 hook 的行为，也没有定义具体的完成测试。
