无法在 rails 中转储文件错误 [英] Can't dump file error in rails

问题描述

我正在使用 Rails 3.0.3 开发应用程序.

I am developing an application with Rails 3.0.3.

我在以下代码中收到无法转储文件"错误.

I got "Can't dump file" error at the following code.

   if @post.update_attributes params[:post]
      redirect_to post_path(@post) #<= ERROR HERE

谷歌搜索后，我添加了 2 行来解决这个问题.

After googling, I added 2 lines to fix that.

   if @post.update_attributes params[:post]
      params[:post][:photos_attributes] = nil
      params[:post][:attachments_attributes] = nil
      redirect_to post_path(@post)

现在错误消失了.但我不明白为什么会发生错误以及它是如何修复的.我将 active_record 用于会话存储，它导致错误，因为文件无法存储在 DB 中.但是为什么redirect_to 尝试在会话中存储文件?

Now the error's gone. But I don't understand why the error occurred and how it's fixed. I use active_record for the session store and it caused the error because a file can't be stored in DB. But why does redirect_to try to store file in the session?

谢谢.
