How to display photos on edit and file_field on new

My form partial is being used to create new, and also for editing.

<% form_for @deal, :html => { :multipart => true } do |f| %>
<%= f.error_messages %>

<%= f.label :city_id %> <%= f.collection_select :city_id, City.find(:all), :id, :name, { :prompt => 'Select a city' }, {:class => 'foobar'} %>

<%= f.label :title %>
<%= f.text_field :title %>

<%= f.label :description %>
<%= f.text_area :description %>

<%= f.label :price %>
<%= f.text_field :price %>

<%= f.label :value %>
<%= f.text_field :value %>

<%= f.label :discount %>
<%= f.text_field :discount %>

<%= f.label :savings %>
<%= f.text_field :savings %>

<%= f.label :goal %>
<%= f.text_field :goal %>

<%= f.label :countdown %>
<%= f.text_field :countdown %>

<%= f.label :purchased %>
<%= f.text_field :purchased %>

<% f.fields_for :photos do |builder| %>


<%= builder.label :photo, “Photos” %>

  <% if [email protected]_record? %>

    <%= image_tag :photo.url(:small) %>
  <% else %>
    <%= builder.file_field :photo %>
  <% end %>

  <br />

  <!--
  <%= builder.check_box :_destroy %>
  <%= f.label :destroy, "Remove photo" %>
  -->

  <%= builder.hidden_field :_destroy %>
  <%= link_to_function "remove", "remove_fields(this)" %>
</p>

<% end %>

<%= link_to_add_fields "Add photos", f, :photos %>

<% f.fields_for :features do |builder| %>


<%= builder.label :description, “Features” %>

<%= builder.text_area :description, :rows => 3 %>

  <!--
  <%= builder.check_box :_destroy %>
  <%= f.label :destroy, "Remove description" %>
  -->

  <%= builder.hidden_field :_destroy %>
  <%= link_to_function "remove", "remove_fields(this)" %>
</p>

<% end %>

<%= link_to_add_fields "Add feature", f, :features %>

<%= f.submit 'Save' %>

<% end %>

Im having trouble with the following lines:

  <% if [email protected]_record? %>

    <%= image_tag :photo.url(:small) %>
  <% else %>
    <%= builder.file_field :photo %>
  <% end %>

  <br />

When I am creating a new deal. The file_field appears appropriately.
But if I am editing a deal with existing photos, I cant get <%=
image_tag :photo.url(:small) %> to show…

All this is inside the <% f.fields_for :photos do |builder| %> loop.
Which is needed for <%= builder.hidden_field :_destroy %> and <%=
link_to_function “remove”, “remove_fields(this)” %>, which are meant
to remove photos when the form is submitted.

How can I get all this to work?

Ok i used <%= image_tag builder.object.photo.url(:small) %> instead of
<%= image_tag :photo.url(:small) %>
Seems to work now
