`@[]' is not allowed as an instance variable name

[newstler]

Hi!

I try to implement this tutorial: http://thewebfellas.com/blog/2010/1/31/paperclip-vs-amazon-s3-european-buckets with Ruby 1.9.2, Rails 3.1.3, Mongoid 2.2.0, mongoid-paperclip 0.0.7, s3 0.3.9

And I get this error:

NameError in PhotosController#create

`@[]' is not allowed as an instance variable name

lib/patches/paperclip.rb:33:in `block in extended'
lib/patches/paperclip.rb:32:in `instance_eval'

My /lib/patches/paperclip.rb is https://gist.github.com/1399954

What could it be?

I've been working on fixing this.

For now try @options.s3_credentials instead of @options[:s3_credentials]. However, even this might not fix it.

I don't fully understand what this monkeypatch is supposed to achieve but it's possible that we've already folded it into Paperclip. @jyurek or @sikachu might have more details.

This monkey patch is for Paperclip to support S3 European buckets throw qoobaa's "s3" gem, insted of aws-s3, which doesn't support eu buckets.

I encountered the same issue, when writing a new storage engine similar to S3

I had the same problem following an upgrade from Paperclip 2.3.11 / Rails 3.1.0 to Paperclip 2.4.5 / Rails 3.2 rc 2; this workaround did the trick for me. Anywhere I had @options show up, I had to switch from bracket notation to dot notation.

After using paperclip's master branch, the problem is solved.
