ruby on rails - Sorting and grouping array, hash with all items appears at the end -

-

i have table leaflets data sorted date in controller:

@leaflets = leaflet.order(:date)

and grouped dates in view (i found code somewhere on internet)

<%= @leaflets.group_by(&:date).each |date, leaflets| %>   <p><%= l(date, :format => '%a, %d %b %y') %></p> <!-- localized date formatting: weekday, day month year -->     <table>     <tr>       <% leaflets.each |leaflet| %>          <td style="border:dotted 1px; padding:5px;">        <strong><%= leaflet.place %></strong><br/>       <%= leaflet.description %><br/>       <%= link_to "zapisz się", leaflet_path(leaflet) %>       </td>       </a>     <% end %>     </tr>    </table>    <% end %>

everything works great, prints items hash @ end:

any idea what's wrong? normal behaviour grouping in rails? how can delete big hash? screenshot: http://imgur.com/nc9sys7

just remove = from:

<%= @leaflets.group_by(&:date).each |date, leaflets| %>

so reads:

<% @leaflets.group_by(&:date).each |date, leaflets| %>

the = outputing results of each call.
