Dynamic Dashing Index

summary.erb

<script type='text/javascript'>
$(function() {
  $('li').live('click', function(e){
    window.location = $(this).find('.widget').data('url');
  });
});
</script>

<% content_for :title do %>Summary<% end %>
<div class='gridster'>
  <ul>
    <% Dir.glob("./dashboards/*").reject {|f| f.match 'layout|summary' }.each_with_index do |d,i| %>
      <% name = d.match(/\.\/dashboards\/(.*)\.erb/)[1] %>
      <li data-row='1' data-col="<%= i+1 %>" data-sizex='1' data-sizey='1'>
        <div data-view='Text' data-title="<%= name.upcase %>" data-url="/<%= name %>"></div>
      </li>
   <% end %>
  </ul>
</div>

Yes - sorry. I was just illustrating the use of erb in the dashboard view rather then pre-generating html.

You can drop in a call to "each_slice(n)" to iterate another variable to use in the data-row attribute, e.g.

<% Dir.glob("./dashboards/*").reject {|f| f.match 'layout|summary' }.each_slice(3).each_with_index do |r, row| %>
   <% row.each_with_index |d,i| %>
      <% name = d.match(/\.\/dashboards\/(.*)\.erb/)[1] %>
      <li data-row='<%= r+1 %>' data-col="<%= i+1 %>" data-sizex='1' data-sizey='1'>
        <div data-view='Text' data-title="<%= name.upcase %>" data-url="/<%= name %>"></div>
      </li>
    <% end %>
<% end %>

Note: above not tested, but you get the idea....

@darwin12 Did you make it work ? Please post your working code.

There were a couple of minor syntax errors, here is a working version of the above with multiple columns. I also made it split dashboard names on "-" or "_" and convert them to title case.

<script type='text/javascript'>
$(function() {
  $('li').live('click', function(e){
    window.location = $(this).find('.widget').data('url');
  });
});
</script>

<% content_for :title do %>Summary<% end %>
<div class='gridster'>
  <ul>
    <% Dir.glob("./dashboards/*").reject {|f| f.match 'layout|summary|.*~' }.each_slice(3).each_wit\
h_index do |row, r| %>
      <% row.each_with_index do |d,i| %>
        <% name = d.match(/\.\/dashboards\/(.*)\.erb/)[1] %>
        <li data-row='<%= r+1 %>' data-col="<%= i+1 %>" data-sizex='1' data-sizey='1'>
          <div data-view='Text' data-title="<%= name.split(/[-_ ]/).map(&:capitalize).join(' ') %>" dat\
a-url="/<%= name %>"></div>
        </li>
      <% end %>
    <% end %>
  </ul>
</div>
