Rails 3.2 Merit Gem Badge not Working

问题

I've read all the current questions and answers about the Merit gem. And attempted to follow the solution given here Rails: Merit Gem Badge Not Registering or Displaying

initializers/merit.rb:

# Use this hook to configure merit parameters
Merit.setup do |config|
  # Check rules on each request or in background
  config.checks_on_each_request = true

  # Define ORM. Could be :active_record (default) and :mongo_mapper and :mongoid
  config.orm = :active_record

  # Define :user_model_name. This model will be used to grand badge if no :to option is given. Default is "User".
  config.user_model_name = "User"

  # Define :current_user_method. Similar to previous option. It will be used to retrieve :user_model_name object if no $
  config.current_user_method = "current_user"
end

# Create application badges (uses https://github.com/norman/ambry)
 # Merit::Badge.create!(

badges = [
  { id: 1, name: 'democratic-society', description: "Voted twice", image: "straight.jpg" }
]
badges.each do |badge|
  Merit::Badge.create!(badge)
end

But after 3 hours of trying I've gotten nowhere. I have a badge listed in sashes and my user has that sash id (badges_sashes returns "empty set" though...) but when I try the following code:

application.html.erb:

<% current_user.badges.each do |badge| %>
  <%= badge.name %>
  <%= badge.description %>
  <%= image_tag (badge.image) %>
<% end %>

badge_rules.rb:

grant_on 'posts#vote_up', :badge => 'democratic-society', :to => :user do |post|
  post.votes
end

There's no error message whatsoever... so I'm at a bit of a loss on what to do next. I can't even get it to display the badge name. Any help would be appreciated. I get absolutely nothing in the view.

posts_controller.rb:

class PostsController < InheritedResources::Base
  before_filter :authenticate_user!, only: [:vote_up]

  def index
    if params[:query].present?
      @posts = Post.tire.search(:query => params[:query])
    else
      @posts = Post.order("created_at desc").paginate(:page => params[:page], :per_page => 15)
    end
  end

  def vote_up
    begin
      current_user.vote_for(@post = Post.find(params[:id]))
      flash[:success] = "Thanks for voting! Be sure to come back to find out the winners!"
      redirect_to [@post]
    rescue ActiveRecord::RecordInvalid
      flash[:error] =  "You have already voted on this one. You're only allowed one vote per song."
      redirect_to [@post]
    end
  end
end

development.log:
