This thread explains whats going on with this, at least until a
solution is put into the paperclip master:


http://groups.google.com/group/paperclip-plugin/browse_thread/thread/50039909a58361e7/ac5f8cbc2479c8ad?show_docid=ac5f8cbc2479c8ad&pli=1#

In this thread felipe sugests doing this:

You could use this as an initializer.

http://gist.github.com/10790

That looks like a nice neat solution for someone like myself who
already has paperclip installed and dosn't want to get a fork of the
plugin installed.

However (neewbie question approaching) I'm making the tiniest little
application as my-first-rails-app and i can't work out where to put
this ( paperclip_initializer.rb ) file.

do i need to do anything else to get it working other than the changes
to the model that are nicely explained in the comments of that file?

Thanks a million for any replies.

Initializers generally go in the directory config/initializers. I think
this has been the case since Rails 2.x (correct me someone if I'm wrong).

In any case, any .rb files placed in config/initializers will get run,
and so that's the best place to put stuff like this.

Hay, thanks for getting back to me. Thats great.

I put it there, thinking "this is just too easy" and sure enough it
didn't work. But reading your comment i thought "i must be doing
something wrong"

And then it occured to me. "turn it off and turn it back on again" I
restarted the rails server in terminal, and hay presto its working.
Brilliant.

I didn't really realise rails has the app running in memory like
that....

Thanks again. Will.

Yep, a lot of the code is reloaded for each request in development mode
(generally anything in a controller or model), but stuff in an
initializer, the main config, or a plugin is only loaded on startup.

Ah, OK. Cool. Id been wondering, since the quickstart says:
"In development mode (which is what you’re working in by default),
Rails reloads your application with every browser request, so there’s
no need to stop and restart the web server."
