Howdy,

Quick question about the aws/s3 library from Marcel… Does that  
require Rails 1.2?

It works great for me when running against the 1.2RC1 gems but if I  
tell my app to require 1.1.6, then I get this error when starting the  
server:

#\<TypeError: ACL is not a class\>

I didn’t see it in the docs but I was curious if 1.2 was required. If  
not, any idea what’s going on?

Thanks,  
Hunter

Having said that, I bet we can get Rails 1.16 to load it up correctly.  
Just  
let me know how you are hooking it into the app. Via the plugins  
directory or  
via rubygems. Where are you referencing it in your app? Required in  
environment.rb or just const missing magic?

Hey Marcel,

I am using aws via gems, not as a plug-in.

I am requiring it in my environment.rb file (and that’s where it is  
choking - if I comment that out, all is well). I am adding the  
following to environment.rb:

require ‘aws/s3’  
include AWS::S3

I then go on to use it in several places in the app.

It works great with 1.2, by the way. It’s just 1.1.6 that chokes.

Cheers,  
Hunter

Ah, that’s what it is. I think ActionWebService has an ACL module, or  
maybe  
someting in ActionMailer does, so since that is already loaded, when you  
include AWS::S3 it sees the ACL class and isn’t happy.

You can instead do

include AWS

And then you should be fine, though you’ll have to change your code to  
say  
S3::Bucket or whatever.

Marcel,

That appears to have worked like a charm.

Thanks,  
Hunter

Hey Marcel,

I seem to see this collision often, such as in the under-development  
attachment\_fu plug in under Rails 1.2.

Is changing the include the best fix or would it make sense to use a  
class name that doesn’t collide?

Thanks again for the work on the gem. I use it every day.

Hunter
