Twitter's activerecord-reputation-system gem + Devise - ruby-on-rails

Question

I am working with Twitter's new activerecord-reputation-system gem, yet it doesn't seem to be registering in my app.
I ran to install (docs have a typo):
gem install activerecord-reputation-system && rails generate reputation_system && rake db:migrate
I've included it in my gemfile and tried pulling directly from github, as well as restarting my local server. The error is the following:
ActionController::RoutingError (undefined method has_reputation' for #<Class:0x007fa7ed783ec0>):
app/models/post.rb:18:in'
app/models/post.rb:1:in <top (required)>'
app/controllers/posts_controller.rb:1:in'
when I try to add votes to posts with this code:
class Post < ActiveRecord::Base
belongs_to :user
has_reputation :votes,
:source => :user,
:aggregated_by => :sum
end
When I try to add votes to users with the same code I get:
undefined method `has_reputation' for #<Class:0x007fa7efb70388>
app/models/user.rb:17:in `<class:User>'
app/models/user.rb:1:in `<top (required)>'
config/routes.rb:4:in `block in <top (required)>'
config/routes.rb:1:in `<top (required)>'
This error occurred while loading the following files:
/Users/username/appname/config/routes.rb
routes.rb, Line 4:
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
Any ideas?

Answer 1

You should require reputation_system in your app. You can do this by adding to your Gemfile:
gem 'activerecord-reputation-system', :require => 'reputation_system'
Update: As of version 2.0.0 you don't need to require reputation_system anymore:
gem 'activerecord-reputation-system'
