Rails how to make conditional inside iteration?

i'm trying to use a conditional inside a iteration but did not worked so, here the scenario:

in this case if the if the order or the product is present should just show the order and products with the feedback.

but even if is present show the feedback with odata and pdata.

someone know why?

<% @feedbacks.each do |feedback| %>
      <% if order.present?  && product.present?  %>
      <% order = feedback.order %>
      <% product = order.product %>
      <% else %>
<% odata = feedback.odata %>
  <% pdata = odata.pdata %>
  <% end %>
