router pluralization mess on rails3 when putting dm-core in gemfile

Reported by makevoid | February 14th, 2010 @ 04:53 PM

Hello,

there's something strange going on with rails3 and dm-core initialization procedure that pluralizes and messes rails3 routes (maybe caused by extlib?)

Anyway.. this is how you can reproduce the issue:

it will print out this:

          GET    /posts(.:format)          {:controller=>"posts", :action=>"index"}
    posts POST   /posts(.:format)          {:controller=>"posts", :action=>"create"}
 new_post GET    /posts/new(.:format)      {:controller=>"posts", :action=>"new"}
          GET    /posts/:id(.:format)      {:controller=>"posts", :action=>"show"}
          PUT    /posts/:id(.:format)      {:controller=>"posts", :action=>"update"}
     post DELETE /posts/:id(.:format)      {:controller=>"posts", :action=>"destroy"}
edit_post GET    /posts/:id/edit(.:format) {:controller=>"posts", :action=>"edit"}

and it's ok!

now! add into your app Gemfile

gem "dm-core"

then the output of rake routes will become:

          GET    /postses(.:format)          {:controller=>"postses", :action=>"index"}
  postses POST   /postses(.:format)          {:controller=>"postses", :action=>"create"}
 new_post GET    /postses/new(.:format)      {:controller=>"postses", :action=>"new"}
          GET    /postses/:id(.:format)      {:controller=>"postses", :action=>"show"}
          PUT    /postses/:id(.:format)      {:controller=>"postses", :action=>"update"}
     post DELETE /postses/:id(.:format)      {:controller=>"postses", :action=>"destroy"}
edit_post GET    /postses/:id/edit(.:format) {:controller=>"postses", :action=>"edit"}

crazy huh? can someone else confirm it? thank you!

    DataMapper and rails3 will not work together seamlessly out of the box. Have a look at the install instructions at

    http://github.com/dkubb/rails3_datamapper

    to get a rails3 app with dm up and running within minutes. The rails3_datamapper railtie takes specific measures to avoid the problem you're seeing. In particular, it relies on forks of dm-core and dm-more that make dm compatible with activesupport instead of extlib, and it injects a module into DataMapper::Resource that makes it compatible with the router. I should note that this module currently doesn't handle composite primary keys properly, but it will, soon.
