我已经发现一些人修复了这个问题，修改了 attr_accessible 但我认为这个错误可能出在 gem rake 本身？

rake --trace db:seed

正如您所说，这与 rake 完全无关，这是一个MassAssignment问题，可以通过修改attr_accessible相关模型来修复。

这里实际发生的是尝试创建模型（我猜）seed执行的任务，并且似乎给出的哈希参数包含一个键，它应该如下所示：rakeUserUser.createauthentication_token

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

但是您的模型在其列表User中没有，所以这就是为什么它在尝试创建.:authentication_tokenattr_accessibleUser

如果您在遇到问题时只需要警告而不是异常MassAssignment，则可以更改配置：

在 config/environment/{development,test,production}.rb

config.active_record.mass_assignment_sanitizer = :strict

只需将 authentication_token 添加到 attr_accessible 例如：我得到的错误

Media1s-Mac-mini:rails_apps media1$ rake clipsfree_import RAILS_ENV=development csvfile=/Users/media1/Desktop/clips/atemp5/demotracks2/import.csv

(See full trace by running task with --trace)

解决方案：在models文件夹的loopsfree.rb中为attr_accessible添加属性title

类 Loopsfree < ActiveRecord::Base attr_accessible :ISRC, :title, :artist, :bpm, :file_name, :genre, :id, :sub_genre end

希望这会有所帮助:) 快乐编码
