>>objecting to user.deals.keys
so yeah if I switch things up (and not iterate but rather define @user
as User.find(:first). It works great for the first user in the array
perfectly well (code below). Its just when I want to iterate over all
of the users that it becomes an issue
>>worked through some of the plethora of tutorials...
yeah - the tutorials are amazing and are what got me this far - I've
come to this discussion board as a last resort for this particular
piece of the app I'm working on.
Controller
def index
@users = User.find :all, :order => 'name ASC'
@user = User.find(:first)
@user_groups = @user.deals.find(:all).group_by {|t|
t.saledate.at_beginning_of_month}
end
View
<ul id="monthly-revs">
<strong><li><%=h Time.now.year %></li></strong>
<% @user_groups.keys.sort.each do |month| %>
<li><%=h month.strftime('%B') %></li>
<li><%=h number_to_currency(@user_groups[month].collect
(&:rev).sum, :precision => 0) %></li>
<% end %>
</ul>
