我've successfully implemented Devise with omniauth-facebook and am now trying my hand at Twitter. I'几乎将Facebook的Devise settings复制到Twitter的方法中 . 但是,在成功批准我的应用程序使用我的Twitter帐户后,我被重定向回我的用户注册页面(http://localhost:3000/users/sign_up) . 为什么是这样?
控制台输出

将调试输出添加到您的twitter回调中,以查看阻止事务提交的确切错误:
众所周知,Twitter在注册过程中不需要电子邮件,因此在针对此类帐户进行操作时可能无法返回值 .
对于这个问题,Devise默认为某些字段提供自动验证 . 来自Devise source:
要关闭默认的电子邮件状态验证,请将其放在
User
模型中:根据您的使用情况,您可能还希望更改默认身份验证密钥以不使用电子邮件:
在 config/initializers/devise.rb :
UPDATE
使用Devise提供的生成器时,
user
表可能会在email
字段上以null: false
约束结束 . 要删除它,请使用以下命令创建迁移:并更新数据库架构:
