Hi,

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
Paperclip::Attachment.default_options.merge!(:preserve_files
=>true)
end
Paperclip::Attachment.default_options.merge!(:preserve_files
=>false)
obj.destroy
end

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

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


obj1.restore_attachment = false
obj1.save
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
deleted.

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.


Cheers,
Venkat.
