端看你希望怎麼讓rails幫你處理上傳的request,如果是一個form裡頭多個照片檔案(一個POST request),那你就必須設 accepts_nested_attributes_for
。
另外一種做法是多個request,即是每上傳一個照片就產生一個Photo record,Form submit的時候再把這些Photo一個個加進blog post.
若有速度考量,第二種方式可以async處理,第一種比較沒有辦法,若request包含太多大容量檔案容易花很多時間甚至是timeout。

其實是沒使用過這種方式,才會上來問問大家的意思,如果用Rails101s的巢狀路由的方法,好像變得綁手綁腳的,主要我還要用來新增或修改多張照片。

@afgnsu check nested_form
.
accepts_nested_attributes_for
對於新增子元素來說是一個非常方便的方式,它會幫你在儲存主物件的時候連同子物件一起存進去
所以當你有一篇文章,而該篇文章有多圖片的時候,用這種方式最為方便

新增很容易,但是想請問一下要如何再次新增/編輯?因為看起來路由是沒有關聯 :P
假設我要再次新增,我該如何讓新增的圖片同屬於原本的部落格文章?用 hidden_field 欄位嗎?

@afgnsu 可以參考 https://gist.github.com/iqbalhasnan/24905170bdfd182cd631
