如何使用设备登录用户? [英] How do I login a user with devise?

问题描述

我有我的 rails 应用程序，但我在设计方面遇到了一个主要问题.我有一个控制器:

I have my rails application and I am running into a major issue with devise. I have a controller:

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

问题是它从不登录用户，它总是停在这一行

The problem is it never logs the user in, it always stops at this line

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

我什至在实际的 gem 文件中放入了大量记录器，看看我是否能看到任何东西但什么也看不到，我真的不知道如何解决这个问题.如果我注释掉这一行，那么用户会登录，但如果电子邮件不在数据库中并且可以使用任何密码(这绝对不是正确的解决方案)

I even put tons of loggers in the actual gem files to see if I could see anything off but nothing and I really have no idea how to fix this. If I comment this line out then the user gets logged in but fails if the email is not in the db and works for any password (which is definitely not the right solution)

我该如何解决这个问题?

How do I fix this?

更新

这有效，但看起来很hackish

this works but seems very 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

推荐答案

如果您想登录用户，请使用控制器操作中的 sign_in 助手:

If you want to sign in a user, use the sign_in helper inside your controller's action:

sign_in(:user, user)
