Hi,
I have a calculation defined like this:
config.columns[:num_payments].calculate = :avg
This works just fine except in this one case.
I have previously used the live search to find some records. The search
is stored in my session.
Next time I come back to this controller the same search will be run.
BUT in the mean time the databases has changed so this search now comes
up empty.
So the calculation is now being called on an empty list. Which results
in this error.
xxxController#index (ActionView::TemplateError) "undefined method
`num_payments' for nil:NilClass"
On line #6 of
vendor/plugins/active_scaffold/frontends/default/views/_list_calculations.html.erb
|
3: <% active_scaffold_config.list.columns.each do |column| -%>
4: <td id="<%= active_scaffold_calculations_id(column) if
column.calculation? %>">
5: <% if column.calculation? -%>
6: <%= render_column_calculation(column) %>
7: <% else -%>
8: |
| 9: <% end -%>
|
The fix is simply to avoid calling the partial list_calculations when
@records is empty.
To do so change
vendor/plugins/active_scaffold/frontends/default/views/_list.html.erb to
(notice line 18):
<table cellpadding="0" cellspacing="0">
<thead>
<tr>
<%= render :partial => 'list_column_headings' %>
</tr>
</thead>
<tbody class="messages">
<tr>
<td colspan="<%= active_scaffold_config.list.columns.length + 1 -%>"
class="messages-container">
<%= render :partial => 'list_messages' %>
</td>
</tr>
</tbody>
<tbody class="records" id="<%= active_scaffold_tbody_id %>">
<% if [email protected]? -%>
<%= render :partial => 'list_record', :collection => @page.items,
:locals => { :hidden => false, :dont_show_calculations => true } %>
<% end -%>
<% if active_scaffold_config.list.columns.any? {|c| c.calculation?} and
[email protected]? -%>
<%= render :partial => 'list_calculations' %>
<% end -%>
</tbody>
</table>
<%= render :partial => 'list_pagination' %>
