在formtastic中访问表单对象

问题描述

所以我正在制作一个调查应用程序.用户在后端选择一种表单类型，在前端显示为某种类型.当然，这只是理想情况.现在发生的是我无法访问 formtastic 正在为其构建表单的对象.我怎么能说question.kind"之类的东西?它只会以这种方式出错.这是我到目前为止所拥有的......

So I'm making a survey app. The users choose a type of form on the backend, and it displays as a certain type on the front end. That's only ideally, of course. What happens now is I can't access the object formtastic is building the form for. How can I say something like "question.kind"? It just makes an error that way. Here's what I have so far...

= semantic_form_for @survey, :url => "#", :html => { :method => "get" } do |f|
  - for question in @survey.questions
    = user_facing_question(f)

到目前为止，辅助辅助方法是这样的:

and the complementary helper method goes like this so far:

def user_facing_question(f)
  f.inputs
end

推荐答案

您可以像这样访问表单的对象:

You can access the form's object like:

f.object
