我正在学习Paperclip:在Rails中附加文件 链接 http://rdoc.info/gems/paperclip/2.3.11/file/README.md
我将这些代码放在show.html.erb上显示图片
<%= image_tag @user.photo.url %>
<%= image_tag @user.photo.url(:thumb) %>
在新页面上,我从计算机浏览文件(.png),然后单击“创建”。 然后我收到了错误
我们很抱歉,但出了点问题。
当我查看development.log时。我发现了这些错误
Status: 500 Internal Server Error

这可能是因为不存在临时目录(在linux上是/ tmp),或者运行该应用程序的用户没有读取/写入权限。
