Question

我有一个从表单发送的两个数据数组，一个名为transloaded，另一个视频是模型的实际表单。我需要[：video_encoded] [：url]并保存到[：video] [：flash_url]

这是传递的参数或转载，当我尝试访问[：transload] [：results] [：video_encode]时我得到了。

print params[:transload]
    {
    "assembly_id":"d59b4293b3d79d2ccd1948c02421c6a6",
    "status":"success",

        }
    }
}

以下是我正在尝试使用的内容

 video_links = {
  :flash_url => params[:transload][:results][:video_encode][:url], 
  :mp4_url => params[:transload][:results][:video_encode_iphone][:url]
}
params[:video].merge(video_links)

Answer 1

问题很简单：:results != "results"或换句话说：您的哈希键具有String类型的键，但您使用Symbol类型访问它们。

合并传递的参数
