I believe that my issue is releated to ticket [http://dev.rails-engines.org/ticket/285](http://dev.rails-engines.org/ticket/285) Has there been any headway on this particular issue?

This bug was fixed in the trunk version of the engines plugin a few days back: [http://dev.rails-engines.org/changeset/681](http://dev.rails-engines.org/changeset/681) If you’re tracking edge rails, you’ll also need to stay use the trunk version of the plugin, available from SVN or github: [http://svn.rails-engines.org/engines/trunk](http://svn.rails-engines.org/engines/trunk) git://github.com/lazyatom/engines.git HTH, James On Thu, Apr 24, 2008 at 2:28 PM, Kevin Pratt ---

Which version of engines are you using? If you’re using Rails 2.0.x, you need to be using engines from the rb\_2.0 branch. You can’t use the trunk version after r681. Rhett ---

Thanks for your help guys. Got that running both on the edge rails as well as the 2.0.2 gem. Now, the reason I was trying to get it installed was I wanted to use date\_box engine. Is this the right list to be asking questions about that particular engine? I keep getting the error undefined method `config’ for DateboxEngine:Module Anyone have any ideas? ---

Thanks for the response. This is exactly what I was wondering. “Does this plugin work with rails 2.0”. Since it does not seem to I’ll dig around and see if I can get it working. Thanks for the help. Kevin ---

The ‘config’ method of setting defaults was removed as part of the 2.0 upgrade - it sounds like this plugin has not been updated to reflect this. To get around it, you might be able to extract the config functionality out of an older version of the engines plugin (have a look through some of the 1.1.x tags on [http://svn.rails-engines.org/](http://svn.rails-engines.org/)), but that’s still no guarantee that this plugin plays well with Rails 2.0, alas.
