Question

我正在从Rails教程和Railscasts身份验证系统从头开始切换到Devise。到目前为止，我已经完成了所有设置，包括安装，配置，创建用户模型和清理旧系统（会话控制器，路由修改等）。

提交sign_up表单时出现错误

/ users / sign_in中的ArgumentError参数数量错误（2为1）

在档案

createdevise (3.2.3) app/controllers/devise/sessions_controller.rb

def create
    self.resource = warden.authenticate!(auth_options)
    set_flash_message(:notice, :signed_in) if is_flashing_format?
    sign_in(resource_name, resource)
    yield resource if block_given?
    respond_with resource, :location => after_sign_in_path_for(resource)
end

sign_in（resource_name，resource）行发生错误。在我的better_errors调试屏幕中，如果我键入resource_name，则返回:user，如果我键入resource，则返回

#<User id: 5, email: "firstname.lastname@example.com", created_at: "2014-03-09 23:20:41", updated_at: "2014-03-10 00:24:02", password_digest: nil, remember_token: "s2BEo5V123ysJ8phH48C", first_name: "firstname", last_name: "lastname", encrypted_password: "$2a$10$KPUF1BQ9RCLRSA4z5vDBIeN...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: "2014-03-09 23:37:06", sign_in_count: 5, current_sign_in_at: "2014-03-10 00:24:02", last_sign_in_at: "2014-03-10 00:01:15", current_sign_in_ip: "1.2.3.4", last_sign_in_ip: "1.2.3.4", failed_attempts: 0, unlock_token: nil, locked_at: nil>

我试图理解我在设置中做错了什么以及sign_in方法需要什么参数。错误是说只有一个参数，我提供了2个，但sign_in帮助器看起来需要2个。

我有没有办法解决这个问题，因为它在设计源代码中？我可以在用户模型或控制器中修复它吗？

我的服务器输出是：

挣扎着找到正确的方式提出这个问题所以任何想法都会受到赞赏。
