如何使用devise登录用户？

Question

我有我的rails应用程序,我遇到了一个设计的主要问题.我有一个控制器:

class Users::SessionsController < Devise::SessionsController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create ]
  include Devise::Controllers::InternalHelpers

def new
    clean_up_passwords(build_resource)

    respond_to do |format|
      format.html { render :layout => "sessions" }
      format.mobile
    end
  end


    # POST /resource/sign_in
    def create
      resource = User.find_by_email(params[:user][:email])  
      resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")
      set_flash_message :notice, :signed_in
      sign_in_and_redirect(resource_name, resource)
    end

end

问题是它永远不会记录用户,它总是停在这一行

resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")

我甚至在实际的宝石文件中放了大量的记录器,看看我是否可以看到任何东西但没有任何东西,我真的不知道如何解决这个问题.如果我注释掉这一行,那么用户就会登录,但如果电子邮件不在数据库中并且适用于任何密码(这绝对不是正确的解决方案),则会失败

我该如何解决？

UPDATE

这有效,但似乎非常hackish

# POST /resource/sign_in
def create
  resource = User.find_by_email(params[:user][:email])

  redirect_to(new_user_session_path, :notice => 'Invalid Email Address or Password. Password is case sensitive.') and return if resource.encrypted_password.blank?      
  bcrypt   = BCrypt::Password.new(resource.encrypted_password)
  password = BCrypt::Engine.hash_secret("#{params[:user][:password]}#{resource.class.pepper}", bcrypt.salt)
  valid = Devise.secure_compare(password, resource.encrypted_password)
 # resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")
  if valid
    set_flash_message :notice, :signed_in
    sign_in_and_redirect(resource_name, resource)
  else
    redirect_to(new_user_session_path, :notice => 'Invalid Email Address or Password. Password is case sensitive.') and return    
  end

end

如果要登录用户,请使用sign_in控制器操作中的帮助程序:

sign_in(:user, user)
