ruby-on-rails - 是否有适用于 Rails 3 的投票插件？

Question

acts_as_voteable 和 vote_fu 在 rails 3 上不工作。有没有一个可以工作？

Answer 1

它们的设置非常简单。您可以从这里开始:

class Object < ActiveRecord::Base
   has_many    :votes, :as => :votable
   has_many    :voting_users,
               :through => :votes,
               :source => :user

#object_controller

  def vote_up
    get_vote
    @vote.value += 1 unless @vote.value == 1
    @vote.save
    respond_to do |format|
      format.html {render :action => 'view'}
      format.js { render :action => 'vote'}
    end
  end

  private

  def get_vote
    current_object = Objects.detect{|r| r.id == params[:id].to_i}
    @object = current_object
    @vote = current_object.votes.find_by_user_id(current_user.id)
    unless @vote
      @vote = Vote.create(:user_id => current_user.id, :value => 0)
      current_object.votes << @vote
    end
  end
