index controller

def index
  @movements = current_user.person.saving.movements.paginate :page => params[:page] || 1 unless current_user.nil? || current_user.person.saving.movements.blank?
end

However I use pagination with will paginate through the page. This pagination run OK but no in dashboard index. I see the page once. however i tried to enter again. Produce this error.

Thanks in advice

Use this in your action:

@movements = current_user.person.saving.movements.paginate :page => params[:page] if current_user.present?
@movements = [] if current_user.blank?

You can probably get rid of @movements = [] if current_user.blank? since you are checking for the existence of current_user in your view anyway.

And this in your view:

<% if @movements.length > 0 %>
    <h2>Balance</h2>
    <%= get_total_balance(current_user) %>

    <h2>Ultimos movimientos</h2>
    <table>
      <th>Fecha</th>
      <th>Debite</th>
      <th>Acredite</th>
      <th>Total</th>
      <% @movements.each do |m| %>
          <tr>
            <td><%= m.date.to_date %></td>
            <td><%= m.debit %></td>
            <td><%= m.credit %></td>
            <td><%= m.balance %></td>
          </tr>
      <% end %>
    </table>
    <%= will_paginate @movements %>
<% else %>
    No hay movimientos para mostrar
<% end %>

How does that work?
