Ruby on rails 没有创建用户会话，知道为什么没有吗？

我正在使用定制的Desive sessions controller来管理我的用户会话，但无论何时我尝试以现有用户身份登录，我的登录功能都不起作用，它只返回登录表单，服务器返回以下消息：

我的会话控制器如下所示：

class Users::SessionsController < Devise::SessionsController
before_action :configure_sign_in_parameters

  def new
   super
  end

  def create
   @user = User.find_by(cell_number: params[:user][:cell_number])
  super
  end

  private

  def after_sign_in_path_for(resource)
   root_path
  end

  def configure_sign_in_parameters
   devise_parameter_sanitizer.for(:sign_in).push(:cell_number, :password)
  end

end

Rails.application.routes.draw do

 ### Admin
 devise_for :admin_users, ActiveAdmin::Devise.config
 ActiveAdmin.routes(self)

 ### User
 devise_for :users, controllers: { :registrations => "users/registrations",
                                :sessions => "users/sessions",
                                :passwords => "users/passwords" }

   devise_scope :user do
   namespace :vodacom do
     namespace :users do
       get "/register", to: 'registrations#new'
       get "/create", to: 'registrations#create'
     end
    end
  end
end

h2 Normal Log in

= simple_form_for @user, url: user_session_path(@user) do |f|
  div class="form-inputs"
    = f.input :cell_number, required: true, autofocus: true
    = f.input :password, required: true
    = f.input :remember_me, as: :boolean if devise_mapping.rememberable?

  div class="form-actions"
    = f.button :submit, "Log in"

我的登录表单如下所示：

class Users::SessionsController < Devise::SessionsController
before_action :configure_sign_in_parameters

  def new
   super
  end

  def create
   @user = User.find_by(cell_number: params[:user][:cell_number])
  super
  end

  private

  def after_sign_in_path_for(resource)
   root_path
  end

  def configure_sign_in_parameters
   devise_parameter_sanitizer.for(:sign_in).push(:cell_number, :password)
  end

end

Rails.application.routes.draw do

 ### Admin
 devise_for :admin_users, ActiveAdmin::Devise.config
 ActiveAdmin.routes(self)

 ### User
 devise_for :users, controllers: { :registrations => "users/registrations",
                                :sessions => "users/sessions",
                                :passwords => "users/passwords" }

   devise_scope :user do

     namespace :users do

       get "/create", to: 'registrations#create'
     end
    end
  end
end

    = f.input :remember_me, as: :boolean if devise_mapping.rememberable?

  div class="form-actions"
    = f.button :submit, "Log in"

知道我做错了什么吗？“我的应用程序控制器”指定在执行任何操作之前应对用户进行身份验证。

我发现我做错了什么，我的用户模型没有电子邮件属性，而是有cell\u number属性。因此，由于我使用Deviate，Deviate默认使用电子邮件作为模型的身份验证密钥。为了解决这个问题，我必须在我的用户模型中指定cell_number作为身份验证密钥：

devise :database_authenticatable,
       :registerable,
       :recoverable, 
       :rememberable,
       :registerable,
       :authentication_keys => [:cell_number]

在45毫秒ActiveRecord中完成401未经授权：2.5毫秒-登录失败。
