Ruby on rails 在公共活动中充当志愿者

我正在开发一个人们可以喜欢帖子的应用程序。我正在使用公共活动宝石并充当Votable

当我尝试查看页面时，出现以下错误：

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

获得选票应该是伴随着表演而来的。我做错了什么

用户模型

class User < ActiveRecord::Base
    acts_as_voter
end

class Activity < ActiveRecord::Base
    acts_as_votable
end

class用户

活动模型

class User < ActiveRecord::Base
    acts_as_voter
end

class Activity < ActiveRecord::Base
    acts_as_votable
end

类活动

查看代码

<% 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 %>

这已经被喜欢了好几次了

活动控制员

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

谢谢你能提供的任何帮助。我正处于知识的边缘。：）

Activity模型位于

PublicActivity

模块中，这意味着它应该可以工作

class PublicActivity::Activity
  acts_as_votable
end

尝试将公共活动gem提取到您的vendor/gems文件夹，并转到/vendor/gems/Public\u Activity-1.4.2/lib/Public\u Activity/orm/active\u record/Activity.rb，然后在那里应用

acts\u as\u votable

，并检查它是否有效。使用Activity.likes.size或更高版本显示使用更改它会返回此错误：未定义的方法“likes”
