以嵌套的形式上傳多張圖片

我有一個嵌套的窗體，用於具有圖片嵌套屬性的項目模型。所有的代碼基本上是相同的https://gist.github.com/mhenrixon/978371 我一直在嘗試使用jQuery文件上傳如railscast 381 所示，但我只能夠上傳一個圖像。據我可以告訴一切看起來應該如此，我不知道問題是什麼！下面是日誌試圖用一個新的項目以嵌套的形式上傳多張圖片

使用您的文件輸入數組中的符號名稱屬性

<input type="file" name="myname" />

您的JavaScript可以像添加多張圖片後：

if (formdata){ 
    formdata.append("myname[]", files); 
}

它也應該反過來工作：

<input type="file" name="myname[]" />

我已經更改name =「item [pictures_attributes] [0] [image]」的名稱屬性，如果它以數組結尾（它被設置爲name =「item [pictures_attributes ] [0] [圖像] []「） – 2013-05-03 12:22:47
