Paperclip preserve files ?


     I am using paperclip to upload files. The problem I am facing is,
based on my object property I need to preserve my file. Means my object
should be deleted from db but the file need to be restored.

     I am using the option :preserve_files => true.
     If I keep the above option in model it will be access to all the
objects of the model. I need to restore only for limited objects.

     for example

     def destroy
       if obj.restore_attachment

     If you observe depending on the attachment property I am setting
the option.

         obj.restore_attachment = true
     For obj.destroy
         obj is getting deleted and file is getting restored.

         obj1.restore_attachment = false
     For obj1.destroy
         obj1 is getting deleted and file is also getting restored.
         For obj1 this should not be happened. The file should also get

         Even I tried passing lambda in the model
      has_attached_file :attachment ,:preserve_files => lambda{|obj|
obj.restore_attachment ? true : false }

     This also behaves as like first approach.

     What I observe is when we set preserve_files => true the paperclip
is taking this option only through out the other requests.

     How to reload paperclip in the code with new options

     Can you please suggest any alternate solution.
