Hi

I am currently setting up my first production environment on a vserver  
and I ran into a problem with the plugin file\_column, respectively  
RMagick.

The image upload via file\_column works, the file is correctly stored  
on the server. But the different versions of the image are not  
generated.

file\_column :image, :magick =\> {  
:versions =\> { “thumb” =\> “50x50”, “medium” =\> “640x480\>” }  
}

RMagick seems to be properly installed and to me, it looks like the  
problem is actually file\_column because the subdirectories for the  
versions (image/id/thumb …) are not being created. I guess if it was  
only a problem generating the thumbnails, at least the directories  
would be created.

What I noticed is, that the uploaded files are owned by root and not  
by the user the server is running. So this could maybe be a permission  
problem? I am totally stuck. The script works great in my development  
environment (cygwin, windows).

I am running a mongrel cluster and deploying with capistrano, RMagick  
version is 1.15.7.

I’d really appreciate any help.  
Thanks

Well, well I finally got it.

Actually for some reason my ImageMagick installation was not working  
correctly and I did not notice.  
I didn’t recheck it since I was sure it’s working and I didn’t find  
anything in the logfiles indicating RMagick or ImageMagick problems.

Sorry and thanks for any efforts.
