Active Admin中的嵌套表单 [英] Nested form in Active Admin

问题描述

我需要帮助！ 我有2个调查模型:

I need help! I have 2 models for a Survey:

class Poll < ActiveRecord::Base

has_many :poll_questions, :dependent => :destroy
accepts_nested_attributes_for :poll_questions, :reject_if => lambda { |a| a[:text].blank?    }, :allow_destroy => true

end

存在以下问题的模型:(看来这些关联是正确的)

There is model for questions as follows: (it seems these assocciations are correct)

class PollQuestion < ActiveRecord::Base
belongs_to :poll
has_many :poll_answers, :dependent => :destroy
accepts_nested_attributes_for :poll_answers, :reject_if => lambda { |a| a[:text].blank? }, :allow_destroy => true

end

活动管理员中的其他内容:

In addition in active Admin:

ActiveAdmin.register Poll do
form do |f|
f.inputs "Main poll" do
  f.input :title
  f.input :description
end

f.inputs do
f.has_many :poll_questions do |question|
  question.input :text
end
end

f.buttons
end

end

它具有漂亮的形式，不会创建实际的问题对象！为什么? 我已经尽力解决了这个问题，但是失败了.

It has a beautiful form that doesnt create an actual question object! why? I've tried my best to solve the problem, but I've failed.

推荐答案

尝试创建对象，

f.has_many :poll_questions, PollQuestion.new do |question|
  question.input :text
end
