铁路局——试图形成设计标志时的错误
原标题:Ruby on Rails - error when trying to render a devise login form

我有这份汉姆档案:

= content_for :page_title do
  = t :page_title_login
= content_for :primary_content do
  #login_box
    .span6
      #traditional-login
        %hgroup
          %h3= t :heading_account_login
        = render "devise/sessions/form"

    .span4

= content_for :before_closing_body_tag do
  configure_login_form(#{request.xhr?.to_s.downcase});

它位于我的<代码>app/views/mobile/sessions/new.haml.html。

造成这一错误:

Showing /Users/alexgenadinik/projects/cmply/cmply-app/app/views/devise/sessions/_form.html.haml where line #1 raised:

undefined local variable or method `resource  for #<#<Class:0x148213358>:0x14820dac0>

但是,在我就此发表意见时:

= render "devise/sessions/form"

它使网页上出现,但没有实际格式。 因此,我认为我需要这条线,我不敢肯定,如何在不犯错误的情况下重新加入这条线。

这里是我的控制者:

class Mobile::SessionsController < ApplicationController
  def create
    redirect_to home

  end

  def new
    redirect_to home
  end
end

任何想法,我会做什么错?

感谢!

最佳回答

部分使用当地变量<代码>资源 它无法找到。

你们必须把这一变量与要求相传。

= render "devise/sessions/form", :locals => {:resource => resource}

您也可能没有其他变量。 www.un.org/Depts/DGACM/index_chinese.htm 或许你们也必须通过这些var。

查阅

BTW, You HAML应当有- content_for not = content_for,因为这是一个控制-quest.
