Object的Authlogic未定义方法“ login_field”

|| 我正在尝试将Authlogic设置为我的默认身份验证系统。我希望用户能够使用其用户名或电子邮件登录。为此，我做了以下工作： app / model / user.rb： 
class User < ActiveRecord::Base

  #add authlogic authentications
  acts_as_authentic do |c|
    c.find_by_login_method :find_by_username_or_email
  end 

  attr_accessible :username, :email, :password, :password_confirmation

  validates :username, :presence => true, 
                       :length => { :within => 3..20 }, 
                       :uniqueness => true, 
                       :format => { :with => /\\A[a-z0-9][a-z0-9\\-]+[a-z0-9]\\z/ }

  validates :email, :presence => true, 
                    :format => { :with => /\\A[\\w+\\-.]+@[a-z\\d\\-.]+\\.[a-z]+\\z/i }, 
                    :uniqueness => { :case_sensative => false },
                    :length => { :maximum => 255 }

  validates :password, :presence => true,
                       :confirmation => true,
                       :length => { :within => 6..40 }

  def self.find_by_username_or_email(username_or_email)
    find_by_username(username_or_email) || find_by_email(username_or_email)
  end

end
app / model / session.rb： 
class Session < Authlogic::Session::Base
end
app / controller / sessions_controller.rb： 
class SessionsController < ApplicationController
  before_filter :require_no_user, :only => [:new, :create]
  before_filter :require_user, :only => :destroy

  def new
    @session = Session.new
  end

  def create
    username = User.find_by_email(params[:session][:username_or_email]).username
    username ||= params[:session][:username_or_email]
    @session = Session.new(params[:session])

    if @session.save
      flash[:notice] = \"Login successful!\"
      redirect_back_or_default :users
    else
      render :action => :new
    end
  end

  def destroy
    current_session.destroy
    redirect_back_or_default new_session_url
  end

end
app / views / sessions / new.html.erb： 
<h1>Sign In</h1>

<%= render \'login_form\' %>
app / views / sessions / _login_form.html.erb： 
<%= form_for @session do |f| %>
  <div class=\"field\">
    <%= f.label \'Username or Email\' %><br />
    <%= f.text_field :login %>
  </div>
  <div class=\"field\">
    <%= f.label :password %><br />
    <%= f.password_field :password %>
  </div>
  <div class=\"actions\">
    <%= f.submit \"Sign In\", :class => \"button\" %>
  </div>
<% end %>
config / routes.rb： 
Test::Application.routes.draw do

  resources :users
  resources :sessions, :only => :create

  match \'/signup\', :to => \'users#new\'
  match \'/signin\', :to => \'sessions#new\', :as => :signin
  match \'/signout\', :to => \'sessions#destroy\', :as => :signout
end
当我运行rails服务器并尝试连接到
http://localhost:3000/signin
时，出现以下错误： 
undefined method `login_field\' for Object:Class

我不太明白为什么会这样。如果我使用的是“ 9”，那么Authlogic为什么还要使用“ 10”？ 更新资料 我更新了代码以匹配Olivier L \'s的答案。控制器无法正常工作，但我认为它要接近得多。 app / models / user.rb： 
class User < ActiveRecord::Base

  #add authlogic authentications
  acts_as_authentic do |c| 
    c.session_class = Session
    c.find_by_login_method :find_by_username_or_email
  end

  attr_accessible :username, :email, :password, :password_confirmation

  validates :username, :presence => true, 
                       :length => { :within => 3..20 }, 
                       :uniqueness => true, 
                       :format => { :with => /\\A[a-z0-9][a-z0-9\\-]+[a-z0-9]\\z/ }

  validates :email, :presence => true, 
                    :format => { :with => /\\A[\\w+\\-.]+@[a-z\\d\\-.]+\\.[a-z]+\\z/i }, 
                    :uniqueness => { :case_sensative => false },
                    :length => { :maximum => 255 }

  validates :password, :presence => true,
                       :confirmation => true,
                       :length => { :within => 6..40 }

  def self.find_by_username_or_email(username_or_email)
    find_by_username(username_or_email) || find_by_email(username_or_email)
  end

end
app / models / session.rb： 
class Session < Authlogic::Session::Base
  authenticate_with User
end
我现在收到错误：

    编辑：好的，我发现了另一个与您基本相同的问题。他接受的答案表明您需要执行以下操作： 
    class Session < Authlogic::Session::Base
  authenticate_with User
end


class User < ActiveRecord::Base
  acts_as_authentic do |c| 
    c.session_class = Session
    c.find_by_login_method :find_by_username_or_email
  end
end
    在此处查找实现多登录字段身份验证的好方法。 以防万一链接断开，这是Michael Cindric在他的博客中建议的内容（已编辑为使用您的类名和字段名）： 
    class Session < Authlogic::Session::Base
  find_by_login_method :find_by_username_or_email
end

class User < ActiveRecord::Base
  def self.find_by_username_or_email(login)
    find_by_username(login) || find_by_email(login)
  end
end
