I’m trying to follow the instructions at [http://wiki.radiantcms.org/Installing\_Extension\_-\_Page\_Attachments](http://wiki.radiantcms.org/Installing_Extension_-_Page_Attachments). When I get to this step: rake production db:migrate:extensions The output is: rake aborted! undefined method `[]’ for #Enumerable::Enumerator:0x24c267c From that point on, my server will no longer start up as well. This is on Leopard, with ruby 1.8.7 (2008-06-09 patchlevel 17) [i686-darwin9.3.0] rails 2.1.0 Any suggestions would be appreciated! ---

I followed the guide (although much of it is outdated and no longer necessary). All you have to do is: 1. Install attachment\_fu: $ svn export [http://svn.techno-weenie.net/projects/plugins/attachment\_fu/](http://svn.techno-weenie.net/projects/plugins/attachment_fu/) vendor/plugins/attachment\_fu 1. Download the page\_attachments extension into the proper directory $ cd /path/to/my/radiant/project $ svn checkout [http://svn.radiantcms.org/radiant/trunk/extensions/page\_attachments](http://svn.radiantcms.org/radiant/trunk/extensions/page_attachments) vendor/extensions/page\_attachments 1. Now run the extension migrations: $ rake production db:migrate:extensions 1. Run the ‘update’ task to copy the appropriate assets from the page\_attachments extension: $ rake production radiant:extensions:page\_attachments:update 1. Restart your application and/or web server. With Phusion Passenger: $ cd tmp $ touch restart.txt ---

I think your problem might be with ruby 1.8.7, there were some changes to Enumerable::Enumerator that are possibly incompatible. Can you try going back to 1.8.6 and see if you get the same error? ---

Why should the user need to downgrade? 1.8.7 is the current stable version of Ruby. It is Radiant that needs to update. Or, if the devs can’t be bothered doing that, at least post a notice on their website saying so. ---

This mailer extension once worked I think. It still sends email but now the attachment part doesn’t work. Am I crazy or missing something? Okay I got the note in the todo list but hey this worked just a couple of months ago. Does it work for other people? Steven ---

We will heartily accept patches that resolve this issue while maintaining compatibility with 1.8.6 and earlier. Sean ---

Just for reference. I solved this with the patch provided in [http://www.mail-archive.com/removed\_email\_address@domain.invalid/msg528878.html](http://www.mail-archive.com/removed_email_address@domain.invalid/msg528878.html). Just add: ---- 8\< ---- unless ‘1.9’.respond\_to?(:force\_encoding) String.class\_eval do begin remove\_method :chars rescue NameError # OK end end end ---- 8\< ---- To your environment.rb (adding it to config/initializers/ as suggested in the URL above won’t work in Radiant). /AITOR
