Hai  
I am using upload\_column for uploading images. Trying to do the user  
registration. For the first time when the user tries to upload image it  
works fine. But when try to update the image an error  
undefined method `process!’ for #UploadColumn::UploadedFile:0x6838424  
occurs.  
in my view I set the multipart=\>true.  
and in controller in the edit action @user = User.find(params[:id])  
and in update action @user.update\_attributes(params[:user]). Do I need  
to add anything more?  
Please help , thanks in advance
