扩展设计登录创建功能，但在执行此功能之前正在进行登录

Question

我在登录前进行额外的密码规则检查。如果检查失败，我会重定向到重置页面。问题是在到达用户登录的创建功能之前。 有没有办法阻止此登录。这是在Rails 3.0.19中，并且在登录时使用了设计（1.4.5）。

module Users
  class SessionsController < Devise::SessionsController
  def create
      user = User.where("email=?", params['user']['email']).first
      if user.valid_password?(params['user']['password'])
        unless user.validate_password_rule?(params['user']['password'])
          session[:reset_email] = user.email
          redirect_to '/user/reset'
        else
          super
        end
      else
        super
      end      
    end
  end
end

的routes.rb

Brc::Application.routes.draw do

  match 'sitemap', :controller => 'sitemaps', :action => 'index'

  devise_for :users, :controllers => {
    :sessions => "users/sessions",
    :passwords => "users/passwords",
    :registrations => "users/registrations",
    :passwords => "users/passwords",
    :confirmations => "users/confirmations"
  } do
    resource :account
  end

  devise_scope :user do
    match "/change_password" => "users/registrations#change_password", :method => :get
  end

  resources :user do
    collection do
      get :home
      get :reset
      post :reset_password
      get :reset_password
    end
    member do
      get :index
    end
  end

  if Rails.env == "test"
    # Hack because I couldn't figure out how to get Rails
    # to programmatically add a route.  See :redirect_initial_subscribers
    # from ApplicationController and its associated spec for the use case.
    resources :test
  end
end
