    class User < ActiveRecord::Base
        has_secure_password
        attr_accessor :account

        has_one :company 
        has_one :employee
        has_many :messages

        def self.authenticate(user, password)
            user = User.find_by_user(user)

            unless user && user.authenticate(password)
                redirect_to new_session_path
            end

            user        
        end 

    end

由于某种原因，我没有得到unless条件内的代码，无法识别任何 Rails 代码，比如那个redirect_to new_session_path或任何其他路径，并抛出这个：

NameError in SessionsController#create

undefined local variable or method "new_session_path" for #<Class:0x2f0e998>

我确实尝试过raise但是是一样的，有人知道为什么会这样吗？谢谢你的帮助。

把它写在你的用户模型中。

 include Rails.application.routes.url_helpers

或者，

使用而不是 new_session_path

Rails.application.routes.url_helpers.new_session_path

模型不应该负责重定向，因为这是控制器的责任。尝试将重定向从模型中拉出并进入控制器。验证方法应该只验证用户是否有效，并让控制器根据该结果采取适当的行动。
