How to Group by Day with Ruport / Ruby on Rails?

Question

I'm trying to evaluate Ruport for use in my Rails app, but am not sure how to take a series of records with date/time stamps and group them via Ruport's grouping functions.

I'm open to other/better methods to do this same grouping if Ruport doesn't make sense.

Answer 1

Without ruport:

<% @posts.group_by {|p| p.created_at.at_beginning_of_day }.each do |day, posts| %>
  <h2><%= day.strftime("something...") %></h2>

  <% posts.each do |post| %>
    do stuff with `post`.
  <% end %>
<% end %>

Use at_beginning_of_month, at_beginning_of_week and so on, depending on what you want to group by.
