If I remove it, it throws a nil object exception which basically means
the object is empty.
I just want to click on this link in search.html.erb:
<a data-remote="true" href="<%= trace_loader_url (tbl_trace)
%>?short_exchange_id=<%= tbl_trace.short_exchange_id %>">
<h6>
<%= tbl_trace.short_exchange_id %>
</h6>
<%= tbl_trace.short_exchange_id %></a>
and it should load the data returned in trace_controller.rb:
def loader
@group_trace = TblTrace.find_by_sql("select top (1) * from tbl_traces
where short_exchange_id = '" + params[:short_exchange_id] + "'
order by created_on desc")
and display in the div in seach.html.erb here:
<div id="loader_div" name="loader_div">
<% if @group_trace %>
<%= render(@group_trace) %>
<% end %>
</div>
