Question

I am trying to implement a highchart that sums hours for a specified week. What it is currently doing is looking at my ‘efforts’ table and summing all records in that table. However I am trying to sum hours for a particular week, for the current user. I have the following snippet from my highcharts.html.erb.

 series: [{
                name: 'Hours',
           data: [<% @efforts.each do |effort| %>
[Date.UTC(<%= effort.week_commencing.strftime("%Y,%m-1,%d") %>),<%= Effort.sum(:hours).                                                                                          
where(:week_commencing => week_commencing, :user_id => current_user.id)%>],<% end %>]

        }]
    });
});

I have the full code available on pastebin http://pastebin.com/ifbQfR0i

Is there a way around this?

Answer 1

I’m not quite sure, but shouldn’t it be:

%>),<%= Effort.sum(:hours). where(:week_commencing => effort.week_commencing, :user_id => current_user.id)%>],<% end %>] }] }); });

instead of

%>),<%= Effort.sum(:hours). where(:week_commencing => week_commencing, :user_id => current_user.id)%>],<% end %>] }] }); });
