Michal. ---

The error could be so many things, these details that you gived are not sufficient… Did you check your log files for any possible error? Are you sure that MiniMagick is working well? The new version of rails is installed correctly? Did you tryed to upload different kinds of files? Give a little more details please On 27 mayo, 02:09, Michal B.

LOL what’s the permission policy? Whichever user is running the app needs write access if you want to write files, unless I’m seriously mistaken.

The problem is probably something similar to [http://blog.methodmissing.com/2008/1/19/edge-callback-refactorings-attachment\_fu/](http://blog.methodmissing.com/2008/1/19/edge-callback-refactorings-attachment_fu/) In my case the method process\_attachment defined as a after\_validation callback doesn’t get called for the second attachment of my model. I replaced beginning of the method: def after\_process\_attachment if save\_attachment? (…) I don’t know what will it cause other than making my attchements work. But they do work now, and I’m glad. ---

Whatever, I don’t know what could it mean. I’m not that familiar with rails unfortunately. The problem is that after migration the attachments stopped working. So if we discuss permissions to file system the first thing that comes to my mind is - did the permission policy changed. The definition of the term “permission policy” I used is from Java environment, cos I’m used to it. For e.g. [http://java.sun.com/j2se/1.4.2/docs/guide/security/permissions.html](http://java.sun.com/j2se/1.4.2/docs/guide/security/permissions.html). I could not find any more suitable. ---
