I have a class which uses paperclip.
So it has the has_attached_file in it.
The class is called story and I need an object of it to be saved in the session because of multiple redirects.
Session_store is mem_cache.
Of course we can't store the file in session but I can' get rid of it.
So my question boils down to this.
How can I remove/clear the file that is attached to the Story after I've tried to save it so that when saving fails I can redirect and have the Story in my session?
Loosing the paperclip/file is no problem by the way.
If you have any questions please ask!
Thank you in advance!

Yeaaaa ... but this means having a lot of additional load as there a plenty people saving stories right now... and this would mean like not double but triple the savings.
I think as far as I've experienced it that for one page redirect putting something in session(or flash or instance variable) isn't a big deal and actually saves time and a lot of headaches.
I have a clue on where the problem with paperclip might be. But please if you know tell me :)
Actually I found the solution myself.
So here is the code that I used to overwrite the standard behavior.
if @story.valid? == false
@story.image.queued_for_wr
else
...
end
So by clearing the queued_for_write was the solution to my problem.
Anyway I think heimidal solution is quite right too. So I'll accept his solution.
Thanks everyone!

Generally, saving an entire object to the session is a bad idea. You can have a look at a rails cast on this subject.
So to get around the problem, you tend to store only a reference to the object in your session.
Something like this:
def update
story = Story.find(params[:id])
story.text = params[:story][:text]
session[:current_story_id]
redirect_to some_other_action_path
end
def some_other_action
story = Story.find(session[:curren
# do stuff to story
end
Hope that helps
