Ruby on rails 使用Desive直接链接登录，但已停止筛选链

因此，我尝试使用身份验证令牌进行直接登录链接，但我在服务器日志中得到了

过滤器链暂停，原因是：在\u令牌\u身份验证呈现或重定向后

此消息仅表示在一个before筛选器中呈现了模板或发生了重定向。在您的情况下，
after\u token\u authentication
过滤器重定向到
contractor\u list\u galleries\u path
，从而结束了before过滤器链。此消息不是错误，显示此消息只是为了告诉您重定向发生在before筛选器中，而不是实际操作。

将其从
@user
更改为
@current\u user
中的
@after\u token\u authentication
。你是
authenticate\u用户
调用需要根据此处设置
@current\u user
：
在\u令牌\u身份验证后将其从
@user
更改为
@current\u user
。你是
authenticate\u用户

，但为什么用户被重定向到登录屏幕？我确信，在重定向之前，用户已通过身份验证，但他仍然获得401未经授权。重定向发生在从
承包商列表\u画廊\u路径
页面重定向之后，因此我无法确定到底发生了什么。可能未设置approved属性，因为我没有看到对
@user.save
行执行另一个更新sql查询。approved已在0处。所以它不会更新它。但我不明白为什么在重定向中，用户不必获得进入画廊的权限，即使我登录了他，然后第二次是after_token_身份验证方法，他不再登录，但为什么用户被重定向到登录屏幕？我确信，在重定向之前，用户已通过身份验证，但他仍然获得401未经授权。重定向发生在从

请检查@current_user.save是否返回真值或假值，如果返回假值，请检查返回假值的原因。这应该是真的，然后它就会工作。请检查@current_user.save是否返回真值或假值，如果是假值，请检查为什么返回假值。这应该是真的，然后它就会起作用。
