ok so then I am where I am having difficulty is associating the user
with the deal and displaying each user's deals. So for example, if I
change the code to the below, then it displays the total sum month to
month as opposed to sum of each user month to month.
View
<% for user in @users %>
<ul id="monthly-revs">
<strong><li><%=h Time.now.year %></li></strong>
<% @deal_groups.keys.sort.each do |month| %>
<li><%=h month.strftime('%B') %></li>
<li><%=h number_to_currency(@deal_groups[month].collect
(&:rev).sum, :precision => 0) %></li>
<% end %>
</ul>
<% end %>
Controller (is the same as above)
def index
@users = User.find :all, :order => 'name ASC'
@deal_groups = Deal.find(:all).group_by {|t|
t.saledate.at_beginning_of_month}
end
