在滑轨中添加按钮单击计数器3 [英] Adding button click counter in rails 3

问题描述

我想在文章上添加按钮，以便知道它在数据库中被点击和更新计数器的次数，我正在使用mongoid，我的模型是:

I want to add buttons on my article so that I can know the number of times its clicked and update counter on the database, I am using mongoid ,my model is:

class Article
  include Mongoid::Document
  include Mongoid::Timestamps
  field :title, :type => String
  field :content, :type => String
  field :likes, :type => Integer ,:default => 0
  field :dislikes, :type =>Integer, :default => 0
  field :spam, :type => Integer, :default => 0
end

我的文章显示控制器为:

My articles show controller is:

  def show
    @article = Article.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render :json => @article }
    end
  end

我的显示视图是:

<p id="notice"><%= notice %></p>

<p>
  <b>Title:</b>
  <%= @article.title %>
</p>

<p>
  <b>Content:</b>
  <%= raw @article.content %>
</p>

Likes : <%= @article.likes %>  <br/>
Dislikes : <%= @article.dislikes %><br/>
Spams : <%= @article.spam %><br/>


<%= link_to 'Edit', edit_article_path(@article) %> |
<%= link_to 'Back', articles_path %>

我在互联网上找到任何有关它的东西.

I find anything about it in internet.

我该如何实现?

推荐答案

最简单的方法是在Article模型中添加click_count整数属性，然后在控制器代码中增加该值:

The easiest thing to do would be add a click_count integer attribute to your Article model and then increment this in your controller code:

def show
  @article = Article.find(params[:id])
  @article.increment! :click_count

  respond_to do |format|
    format.html # show.html.erb
    format.json { render :json => @article }
  end
end
