Problem with Paperclip

[RanzQ]

Hi,

I followed this tutorial:

http://cookbook.hobocentral.net/plugins/paperclip_with_hobo

But when I try open the new-page of my model, I get this error:

Unable to generate hash without :hash_secret

It seems to be raised from the hash() method in Paperclip::Attachment.

What should I do to fix this?

Looks like you'll need to pass :hash_secret to the has_attached_file method in your model.

Thanks for the answer, that probably would have fixed it, that seems
to be a key for the filepath hash.

I ended up using attachment_fu plugin which had some problems too with
the new ruby but I got it working finally.

Just in case anyone is also dealing with this "hash_secret" issue
(with Hobo 1.3, Rails3), note that it is an open issue at Thoughtbot's
repo here:

https://github.com/thoughtbot/paperclip/issues/450

For anyone who needs an immediate patch, there is a forked version
here that deals with the hash_secret problem:

https://github.com/jeanmartin/paperclip.git

So, at a pinch, your Gemfile can reference this using:

gem 'paperclip', :git => "git://github.com/jeanmartin/
paperclip.git", :branch => "master"

As Bryan Larsen kindly pointed out, Paperclip versions up to 2.3.9
appear to have a dependency locked to activesupport v2.3.2. Paperclip
versions 2.3.10 and later allow activesupport v2.3.2 and later (and
are therefore okay for Rails 3).
