How do I use the Impressionist gem?

Question

I'm using the Impressionist gem.

I want to display a hit counter of one particular page, in that same view.

This is what I did:

1. Install the gem.
2. Run generator.
3. Add column counter_cache to the migration.
4. Run rake db:migrate .
5. Add impressionist :actions=>[:show ] to the controller that I want to track impressions from.
6. Add is_impressionable :counter_cache => true to the model pertaining to the controller above.
7. Restart server.

I have two questions:

1. Why doesn't the counter_cache number get increased for each impression (and each respective record)?
2. Is there any method I can use in the view to display the hit count, or should I craft my own query?

Answer 1

There is a method to show how much hits:

<%= @model_instance.impressionist_count %> views

Put this in your view.
