I am using the Ahoy gem in a Rails 4.2 app. Ahoy Events stores events with a number of text attributes and a properties attribute that contains data I want to query. For example here is the last event I return via the rails console
>> Ahoy::Event.last
Ahoy::Event Load (3.8ms) SELECT "ahoy_events".* FROM "ahoy_events" ORDER BY "ahoy_events"."id" DESC LIMIT 1
=> #<Ahoy::Event id: "fffff17f-44e6-41d7-9c32-fa895338f54e", visit_id: "6b05b1ca-3863-46da-9c48-a3ab5fa4a9ee", user_id: 1, name: "$click", properties: {"tag"=>"a", "page"=>"/conversations/2", "text"=>"View", "href"=>"/conversations/2"}, time: "2015-08-23 13:25:51">
How would I retrieve all events where properties['text'] = 'View'
I have tried Ahoy::Event.where(:properties['text'] => 'View').count
which returns: ```
Ahoy::Event.where(:properties['text'] => 'View').count NoMethodError: undefined method

I have looked online for querying hash attributes without success. Any guidance is much appreciated.
Ahoy::Event actually doesn't return anything useful. To get all records in an array return object, you need to use Ahoy::Event.all.
So what you actually need to do is something along the lines of this:
Ahoy::Event.all.select { |event| event.properties['text'] == "View" }.size
The run time isn't going to be that nice but I think this is what you need.
