Rails 中页面视图的简单命中计数器 [英] simple hit counter for page views in rails

问题描述

我为这个问题找到了几种解决方案，例如这篇文章中的 railstat:

I've found several solutions for this problem, for example railstat from this post:

Rails 中的页面浏览量

我有很多文章和评论，我想要一个按唯一 IP 过滤的点击计数器.就像 Stackoverflow 在这篇文章中所做的一样.但是当谷歌分析已经为我做这件事并包括大量代码、跟踪唯一 IP 等时，我并不真正关心像 railstat 这样的解决方案.我目前的想法是使用 Garb 或其他一些分析如果页面更新时间超过 12 小时，则可以使用插件来提取页面统计信息，但我还需要一个 cache_column.

I have a bunch of articles and reviews which I would like a hit counter filtered by unique IPs. Exactly like Stackoverflow does for this post. But I don't really care for such a solution as railstat when google analytics is already doing this for me and including a whole lot of code, keeping track of unique IPs, etc.. My present thinking is to use Garb or some other Analytics plugin to pull the pages stats if they are older than say 12 hours updating some table, but I also need a cache_column.

我假设您可以从 Analytics 中提取特定页面的统计数据，并且他们每 12 小时更新一次统计数据?

I'm assuming you can pull stats from Analytics for a particular page and that they update their stats every 12 hours?

我想知道是否有任何理由表明这是一个坏主意，或者是否有人有更好的解决方案?

I'm wondering if there are any reasons why this would be a bad idea, or if someone has a better solution?

谢谢

UPDATE

此答案中的代码用作 http://github.com/charlotte-ruby 的基础/印象派试试看

The code in this answer was used as a basis for http://github.com/charlotte-ruby/impressionist Try it out

将其编码到您的应用中可能会花费更少的时间，然后使用他们的 API 从 Analytics 中提取数据.这些数据很可能会更准确，而且您不必依赖外部依赖......而且您将获得实时统计数据，而不是等待 12 小时的 Analytics 数据.request.remote_ip 效果很好.这是使用多态的解决方案.请注意，此代码未经测试，但应该是关闭的.

It would probably take you less time to code this into your app then it would to pull the data from Analytics using their API. This data would most likely be more accurate and you would not have to rely an an external dependancy.. also you would have the stats in realtime instead of waiting 12 hours on Analytics data. request.remote_ip works pretty well. Here is a solution using polymorphism. Please note that this code is untested, but it should be close.

创建一个新模型/迁移来存储您的页面浏览量(印象数):

Create a new model/migration to store your page views (impressions):

class Impressions < ActiveRecord::Base
  belongs_to :impressionable, :polymorphic=>true 
end

class CreateImpressionsTable < ActiveRecord::Migration
  def self.up
    create_table :impressions, :force => true do |t|
      t.string :impressionable_type
      t.integer :impressionable_id
      t.integer :user_id
      t.string :ip_address
      t.timestamps
    end
  end

  def self.down
    drop_table :impressions
  end
end

在您的文章模型中为关联添加一行并添加一个方法来返回展示次数:

Add a line to your Article model for the association and add a method to return the impression count:

class Article < ActiveRecord::Base
  has_many :impressions, :as=>:impressionable

  def impression_count
    impressions.size
  end

  def unique_impression_count
    # impressions.group(:ip_address).size gives => {'127.0.0.1'=>9, '0.0.0.0'=>1}
    # so getting keys from the hash and calculating the number of keys
    impressions.group(:ip_address).size.keys.length #TESTED
  end
end

为显示操作上的articles_controller 创建before_filter:

Create a before_filter for articles_controller on the show action:

before_filter :log_impression, :only=> [:show]

def log_impression
  @article = Article.find(params[:id])
  # this assumes you have a current_user method in your authentication system
  @article.impressions.create(ip_address: request.remote_ip,user_id:current_user.id)
end

然后您只需在视图中调用 unique_impression_count

Then you just call the unique_impression_count in your view

<%=@article.unique_impression_count %>

如果你在一堆模型上使用它，你可能想把它弄干.将 before_filter def 放在 application_controller 中并使用动态的东西，例如:

If you are using this on a bunch of models, you may want to DRY it up. Put the before_filter def in application_controller and use something dynamic like:

impressionable_class = controller_name.gsub("Controller","").constantize
impressionable_instance = impressionable_class.find(params[:id])
impressionable_instance.impressions.create(ip_address:request.remote_ip,user_id:current_user.id)

并且还将文章模型中的代码移动到将包含在 ActiveRecord::Base 中的模块中.您可以将发送包含放在配置/初始化程序中...或者如果您想发疯，只需将整个内容转换为 Rails 引擎，以便您可以在其他应用程序上重复使用.

And also move the code in the Article model to a module that will be included in ActiveRecord::Base. You could put the send include in a config/initializer.. or if you want to get crazy, just turn the whole thing into a rails engine, so you can reuse on other apps.

module Impressionable
  def is_impressionable
    has_many :impressions, :as=>:impressionable
    include InstanceMethods
  end
  module InstanceMethods
    def impression_count
      impressions.size
    end

    def unique_impression_count
      impressions.group(:ip_address).size
    end
  end
end

ActiveRecord::Base.extend Impressionable
