Acts As Votable With Public Activity

Question

I'm working on an app where people can like posts. I'm using the Public Activity gem and Acts As Votable.

I'm getting this error when I try to view the page:

undefined method 'get_upvotes' for PublicActivity::Activity:0x00000101453ad8

get_upvotes is supposed to come with acts_as_votable. What am I doing wrong?

User Model

class User < ActiveRecord::Base
    acts_as_voter
end

Activity Model

class Activity < ActiveRecord::Base
    acts_as_votable
end

View Code

<% if activity.owner == current_user %>
    <i>This has been liked <strong><%= activity.get_upvotes.size %></strong> times</i>
<% else %>
    <%= link_to like_activity_path(activity),  class: "like", method: :put do %>
      <button type="button" class="btn btn-info" aria-label="Left Align">
        <span class="glyphicon glyphicon-thumbs-up glyphicon-align-center" aria-hidden="true"></span>
        <span class="badge"><%= activity.get_upvotes.size %></span>
      </button>
    <% end %> 
    <a class="btn btn-default btn-xs timeline-button"><i class="fa fa-heart"></i> I Liked This</a>
<% end %>

Activities Controller

class ActivitiesController < ApplicationController

    before_action :authenticate_user!, only: [:index, :upvote]

    def index
        @users = current_user.active_friends
        @users.push(current_user)
        case params[:content] when 'posts'
            @activities = PublicActivity::Activity.where(owner_id: @users, trackable_type: "Post").paginate(page: params[:page], per_page: 6).order('created_at DESC')
        else
            @activities = PublicActivity::Activity.where(owner_id: @users).paginate(page: params[:page], per_page: 6).order('created_at DESC')
        end
    end

    def upvote
        @activity = Activity.find(params[:id])
        @activity.upvote_from current_user
        redirect_to activities_path
    end

end

Thanks for any help you can offer. I'm at the edge of my Rails knowledge. :)

Try extracting the **Public Activity** gem to your vendor/gems folder and goto **/vendor/gems/public_activity-1.4.2/lib/public_activity/orm/active_record/activity.rb** and apply `acts_as_votable` there and check if it works. — Abhi, Apr 29 '15 at 11:23
use activity.likes.size or more better to display use <%=number_to_human( activity.likes.size) %> — Milind, Apr 29 '15 at 12:07

The Activity model lives inside the PublicActivity module, meaning this should work.

class PublicActivity::Activity
  acts_as_votable
end
