ruby-on-rails - 在 Rails 3 中为 form_for 传递非 AR

Question

我想在登录表单中执行此操作，
我只想在用户提交数据时保留数据，但这是无效的。

下面的代码：

在控制器中：

def login

    if request.request_method == "POST"
        @session = params[:session]
    end

    render "login",
           :layout => "admin_login"
end

和admin_login模板：

= form_for :session, :url => { :action => "login", :controller => "administrator" }, :html => { :class => "form-horizontal" } do |f|

  %div.control-group
    #{f.label :token, "User / Email", :class => "control-label" }
    %div.controls
      #{f.text_field :token}

  %div.control-group
    #{f.label :password, "Password", :class => "control-label" }
    %div.controls
      #{f.password_field :password}

但是当我提交表单时它会抛出异常，说undefined method 'token'

谢谢

如果您不处理资源，则应使用form_tag

= form_tag { action: 'login', controller: 'administrator' }, class: 'form-horizontal' do
  %div.control-group
    %label.control-label User / Email

    %div.controls
      = text_field_tag :token

  %div.control-group
    %label.control-label Password

    %div.controls
      = password_field_tag :password
