我有一個模型，「更新」has_many「資產」。資產具有has_attached_file：資產，使用回形針。另外，非回形針屬性忽略更新模型時通過accept_nested_attributes_for
我可以通過我的更新表單（使用fields_for）成功創建多個資產，但在編輯更新時，我無法更新資產上名爲「sort_order」的附加非Paperclip屬性。新值已發佈，但該對象似乎沒有更新。
型號/ asset.rb
...
belongs_to :update
...
型號/ update.rb
has_many :assets, :dependent => :destroy
...
accepts_nested_attributes_for :assets, :allow_destroy => true
attr_accessible
。
的意見/更新/ _form.html.erb
<ul class="existing-images">
<%= f.fields_for :assets do |a| %>
<% unless a.object.new_record? %>
<li>
<%= link_to image_tag(a.object.asset.url(:small)), a.object.asset.url(:original) %>
<%= a.check_box :_destroy %>
<%= a.label :_destroy %>
<%= a.text_field :sort_order %>
<%= a.label :sort_order %>
</li>
<% end %>
<% end %>
</ul>
在上面的a.text_field :sort_order領域，出現了資產的默認排序順序，但不能更新。
輸入到該字段的新值被髮送作爲每日誌：

Update Load (0.1ms) SELECT "updates".* FROM "updates" WHERE "updates"."id" = 1 LIMIT 1
[paperclip] Saving attachments.
（「SORT_ORDER」 =>「20」是新的值），但該值不被保存。
儘管_destroy複選框按預期工作，也是如此。
希望這是足夠的信息;如果任何人都可以幫助，我會很感激！
