通过生成迁移添加列:
rails generate migration AddPasswordToUsers password:string 然后运行: rake db:migrate 但是,您似乎尝试使用has_secure_password,但尚未将其添加到用户模型中.如果是这种情况,请将行has_secure_password添加到您的用户模型并改为运行此迁移: rails generate migration AddPasswordDigestToUsers password_digest:string (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
