title: Rails 4 Authentication using Devise with MongoMapper
body: <p>I am working on a Rails 4 app and would like to use MongoMapper and Devise for authentication.  When I add devise to my Gemfile and bundle install it goes fine and I am able to <code>rails g devise:install</code>, and it picks up that I am using MongoMapper as my ORM.  When I try to <code>rails g mongo_mapper:config</code> it says it cannot find the generator.  Also I know that Devise supports Mongoid by default, but I like MongoMapper and would like to stick with that.  I downgraded to Rails 3.2.14 and it seems to work fine.  Any ideas on what I may be overlooking, or if Devise/MongoMapper support each other in Rails 4?</p>
