未在编辑中填充活动的管理员嵌套模型

Question

所以，我一直在修改 Active Admin，到目前为止，尽管文档不是很好，但我一直在航行。但是当我尝试编辑具有一些 belongs_to 关联的模型时遇到了一个问题。该表单没有填充这些关联的记录......并且由于 Active Admin 通过魔术做了很多事情，我不知道问题可能是什么，因为正如我所说，Active 的文档有些缺乏管理员，就我的搜索而言，没有人遇到过类似的问题......所以，我对想法持开放态度。

我得到了所有情侣属性的记录，但婚礼、新娘和新郎什么都没有

models/couple.rb

class Couple < ActiveRecord::Base
 after_create :set_full_name
 belongs_to :wedding, :dependent => :destroy
 belongs_to :groom, :class_name => "Partner::Groom", :dependent => :destroy
 belongs_to :bride, :class_name => "Partner::Bride", :dependent => :destroy
 accepts_nested_attributes_for :groom, :bride, :wedding
 attr_accessible :bride, :groom, :bride_id, :groom_id, :notification_email, :contact_address,     :comment,:bride_attributes, :groom_attributes, :wedding_attributes
 validates :notification_email, email: true, uniqueness: true, presence: true
 validates :contact_address, presence: true
 validates :wedding, :groom, :bride, presence: true
end

admin/couples.rb

ActiveAdmin.register Couple do

Answer 1

所以，我发现了问题所在......既然我已经修复了它，我想把我发现的问题留在这里，所以如果其他人遇到同样的问题，他们会有答案。

显然我为嵌套模型构建了错误的表单，而不是

c.inputs :for => :groom_attributes do |g|

我用过

c.inputs for: [:groom, c.object.groom || c.object.build_groom] do |g|

admin/couples.rb

ActiveAdmin.register Couple do
  menu :priority => 3, url: ->{ admin_couples_path(locale: I18n.locale) }, :label => proc{I18n.t('general.couples')}

  scope proc{I18n.t('admin.couples.scope.all')},:all, :default => true
  scope proc{I18n.t('admin.couples.scope.past_week')},:past_week do |couples|
    couples.where('created_at >= ? and created_at <= ?', Time.now - 1.week, Time.now)
  end
  scope proc{I18n.t('admin.couples.scope.last_month')},:last_month do |couples|
    couples.where('created_at >= ? and created_at <= ?', Time.now - 1.month, Time.now)
  end
