How to graph impressions with chartkick and impressionist?

Question

I'm using Impressionist gem to capture impressions for records, and I'm using chartkick to graph the results. What I would like to do, is count the impressions for the current_user's records, and display the count on chartkick. Its a simple issue, but I cannot seem to figure out why the impressions are not being displayed on the graph. My code is below

analytics.html.erb

<%= line_chart current_user.posts.sum(&:impressionist_count).group_by_hour(:created_at).count, refresh: 60, xtitle: 'Hourly Posts Impression Count', ytitle: 'Amount of Views', label: 'View Count' %>

Answer 1

I found a solution to this problem. Just in case anyone has it in the future. The code below, will inject the sum of the impressions into a hash, and then it will display correctly on the graph.

<%= line_chart current_user.posts.group_by_day(:created_at).count.inject(Hash.new(0)) { |acc, (k,v)| acc[:impressionist_count] += v; acc[k] = acc[:impressionist_count]; acc }.except(:impressionist_count) %>
