Hi there, We’re using engines heavily in our current app - problem is that we’ve seen the lovely patch DHH just committed to edge rails to allow easy namespacing of routes ( [http://railstips.org/2007/4/28/namespaces-added-to-routes](http://railstips.org/2007/4/28/namespaces-added-to-routes) ). We’d really like to move to edge to take advantage of this but we’re so heavily dependant on the current release of engines that we can’t afford to break that. So - anyone know of any issues with edge rails and the current stable release of engines? Would we have to move over to an edge version of engines as well? Cheers, David ---

This was when trying edge rails with stable engines 1.2. Has this been fixed in edge engines? Can we expect any compatibility or am I well worth leaving this alone until Rails 1.2.4? - I really would like to use the name space routing 😃 ---

The biggest problematic change in Edge Rails that will affect engines is the new plugin loading mechanism, which will conflict with the way that the engines plugin (see a post on this thread by Rhett for the specific changeset). Because we don’t develop against Edge at work (in general), we’ve not needed to deal with this problem yet. It requires some thought because the direction core has taken the plugin loading mechanism doesn’t suit my needs. In a nutshell, do provide a new “PluginLoader” class, that class needs to be available on the load path before the initializer starts up. That’s going to mean either repackaging the engines plugin as a gem and adding “gem ‘engines’” to the top of environment.rb, or some other dastardly hack. I’m still undecided. Any thoughts? It’s worth noting that until there’s a pressing need here for the plugin to work with Edge rails, it won’t get much attention, but if any of you have the need, please do discuss possible approaches, and submit patches! [http://dev.rails-engines.org/](http://dev.rails-engines.org/) is your playground! Cheers, James ---

Hi James, I’d like to get a patch together so that Engines will once again work in Edge. I see that there is a trunk in subversion that was updated 7 months ago and a 1.2 branch that is more recent. I also see that though there are tests in the trunk they are not found in the branch. Which one should I develop my patch off of? Thanks, Rob K.

Has anyone got engines working with edge yet? I’m freaking out over here trying to get TzTime rolling (which requires edge). It’d be great to see something. Anyone patched the code yet? ---

When I was first trying out engines a few weeks ago, I tested it with edge. At the time, it wouldn’t work. I tracked the problem back to this edge change: [http://dev.rubyonrails.org/changeset/6277](http://dev.rubyonrails.org/changeset/6277) At the time, the engines trunk didn’t have a fix, but it could have one now. (I’ve since been using rails 1.2.3 with the 1.2-stable branch of engines, so I’m not keeping up with this.) Rhett ---

Hi Rob, Sorry - I must’ve missed your message (I don’t know how reliably the ruby-forum is at passing things through…?). Anyway: Until about 5 minutes ago, the HEAD was in branches/rb\_1.2 - I had postponed merging anything into the trunk, because I hadn’t yet decided how to tackle some of the more significant changes in edge Rails. However, I’ve just replaced the trunk with a copy of branches/rb\_1.2 - please use this to develop your patches. Thanks, James ---

I posted this a little while ago to the ruby-forum, but never heard back. I have a copy of engines working on Edge (at least edge as of a few weeks ago) but as I’m not sure which repository is the current HEAD I don’t know where to patch against. Hi James, I’d like to get a patch together so that Engines will once again work in Edge. I see that there is a trunk in subversion that was updated 7 months ago and a 1.2 branch that is more recent. I also see that though there are tests in the trunk they are not found in the branch. Which one should I develop my patch off of? Thanks, Rob K.
