我如何使用印象派宝石？

Question

I'm using the Impressionist gem. 我正在使用印象派瑰宝。

I want to display a hit counter of one particular page, in that same view. 我想在同一视图中显示一个特定页面的点击计数器。

This is what I did: 这是我所做的：

Install the gem. 安装宝石。
Run generator. 运行发电机。
Add column counter_cache to the migration. 将列counter_cache添加到迁移中。
Run rake db:migrate . 运行rake db:migrate 。
Add impressionist :actions=>[:show ] to the controller that I want to track impressions from. 将impressionist :actions=>[:show ]添加到我要从中跟踪印象的控制器。
Add is_impressionable :counter_cache => true to the model pertaining to the controller above. 将is_impressionable :counter_cache => true添加到与上述控制器有关的模型。
Restart server. 重新启动服务器。

I have two questions: 我有两个问题：

Why doesn't the counter_cache number get increased for each impression (and each respective record)? 为什么每次展示（以及每个记录）的counter_cache数量都没有增加？
Is there any method I can use in the view to display the hit count, or should I craft my own query? 我可以在视图中使用任何方法来显示点击计数，还是应该编写自己的查询？

Answer 1

There is a method to show how much hits: 有一种方法可以显示点击量：

<%= @model_instance.impressionist_count %> views

Put this in your view. 把它放在您的观点。
