我正在使用窗體中的另一個嵌套窗體，我想更新嵌套的元素，但它不工作...rails 3.2嵌套窗體不會調用更新時，我發送它
ENV：3.2的Rails
_form.html.haml
= simple_form_for [:pim, activity]
...
= f.simple_fields_for :pictures do |pic_form|
%div.media
.pull-left.col-md-2
= image_tag pic_form.object.image.mini.url
%div.media-body.col-md-5
= pic_form.input :alt
= pic_form.input :element_id, as: :hidden
= pic_form.input :element_type, as: :hidden
= pic_form.input :_destroy, as: :hidden
活動具有X圖片：
ACTIV ity.rb
has_many :pictures, :as => :element, :dependent => :destroy
...
accepts_nested_attributes_for :pictures, allow_destroy: true
當我修改嵌套元素的輸入端，服務器跟蹤是：
Picture Load (0.3ms) SELECT "pictures".* FROM "pictures" WHERE "pictures"."element_id" = 13579 AND "pictures"."element_type" = 'Activity' AND "pictures"."id" IN (9839, 9840, 9838)
但0更新中... 0錯誤...
你有什麼想法發生了什麼？我嘗試了很多解決方案，但他們不工作。 謝謝。
編輯：我忘了，但在活動的的form_for它編輯兩個嵌套形式和第二種形式的作品非常好.......

你可以分享問題中'update'行動的代碼。此外，添加表單提交時獲得的完整服務器日誌，包括'params'哈希。 –
