Question

我正在尝试部署我的rails应用程序。我在这里有一个小要求。

我没有使用Devise。我通过他的用户名和密码提供用户登录。但现在我也想通过他的电子邮件提供用户登录。

我该怎样才能做到这一点。它应该适用于用户名和电子邮件。

我的访问控制器登录操作如下：

  def attempt_login
    if params[:username].present? && params[:password].present?
      p 'Fields Check'
      found_user = User.where(:username => params[:username]).first
      p "#{@found_user.inspect}"
      if found_user
        authorized_user = found_user.authenticate(params[:password])
      end
    end
    p "#{authorized_user.inspect}"
    if authorized_user
      if authorized_user.email_confirmed
        # mark user as logged in
        session[:user_id] = authorized_user.id
        session[:username] = authorized_user.username
        redirect_to(:controller => 'users',:action => 'index')
      else
        flash[:error] = 'Please activate your account by following the
        instructions in the account confirmation email you received to proceed'
        redirect_to(:controller => 'home',:action => 'index')
      end
    else
      p "Not a Registered User"
      flash[:error] = "Invalid username/password combination."
      redirect_to(:controller => 'home',:action => 'index')
    end
  end

提前致谢：）

您只需更改初始检查，如下所示

if (params[:username].present? || params[:email].present?) && params[:password].present?

然后查询用户

User.where('username= ? OR email= ?', params[:username], params[:email]).first
