attr_accessibleを変更してこの問題を修正している人をすでに見つけましたが、このエラーはgem rake自体にあるのではないかと思いますか？

rake --trace db:seed

これは問題であるとおっしゃっていたように、レーキとはまったく関係ありません。関連するモデルをMassAssignment変更することで修正できます。attr_accessible

ここで実際に行われるのは、seedによって実行されるタスクがrakeモデルを作成しようとすることです（私は推測します）。キーを含むUserように指定されたハッシュパラメータのようです。次のようになります。User.createauthentication_token

User.create name: 'foo', email: 'mail@bar.com', authentication_token: 'qfgsdgf' ...

ただし、モデルのリストには含まれてUserいないため、を作成しようとするとこのエラーがスローされます。:authentication_tokenattr_accessibleUser

MassAssignment問題が発生したときに例外ではなく警告が必要な場合は、構成を変更できます。

config / environment / {development、test、production}.rbにあります

config.active_record.mass_assignment_sanitizer = :strict

authentication_tokenをattr_accessibleに追加するだけです。例：取得したエラー

解決策：modelsフォルダーのloopsfree.rbのattr_accessibleに属性タイトルを追加しました

class Loopsfree <ActiveRecord :: Base attr_accessible：ISRC、：title、：artist、：bpm、：file_name、：genre、：id、：sub_genre end

これがお役に立てば幸いです:)ハッピーコーディング
