How can I display a 'nothing entered yet' message for when theres no records?

In my app I have venue records where each one can have many photos and reviews.

How can I go about displaying a 'nothing entered yet' message where the photos or reviews should be displayed when there isn't any?

Heres how I'm currently displaying them:

Review

  <div id="reviews">
    <%= render :partial => 'reviews/review', :collection => @venue.reviews %>
  </div>

Photos (displayed using colorbox)

  <div class="venue_photos_container">
    <div class="ppy4" id="ppy4">
      <ul class="ppy-imglist">
        <% for venuephoto in @venue.venuephotos %>
          <li class="venue_photo_thumb_container"><%= link_to image_tag(venuephoto.venuephoto.url(:image_scroller), :class => "venue_photo"), venuephoto.venuephoto.url(:large), :rel => "venue_photo_colorbox" %></li>
        <% end %>
      </ul>
      <div class="ppy-outer">
        <div class="ppy-stage">
          <div class="ppy-nav">
            <a class="ppy-prev" title="Previous image">Previous image</a>
            <a class="ppy-switch-enlarge" title="Enlarge">Enlarge</a>
            <a class="ppy-switch-compact" title="Close">Close</a>
            <a class="ppy-next" title="Next image">Next image</a>
   开发者_开发百科       </div>
        </div>
      </div>
    </div>
  </div>

Thanks for any help its much appreciated!

I would count the venue photos and run the count through a conditional statement. If it's zero display "no pics" otherwise display the photos.

<div class="venue_photos_container">
  <div class="ppy4" id="ppy4">
    <% if @venue.venuephotos.count.zero? %>
      Sorry, no pictures!
    <% else %>
      <ul class="ppy-imglist">
        <% for venuephoto in @venue.venuephotos %>
          <li class="venue_photo_thumb_container"><%= link_to image_tag(venuephoto.venuephoto.url(:image_scroller), :class => "venue_photo"), venuephoto.venuephoto.url(:large), :rel => "venue_photo_colorbox" %></li>
        <% end %>
      </ul>
      <div class="ppy-outer">
        <div class="ppy-stage">
          <div class="ppy-nav">
            <a class="ppy-prev" title="Previous image">Previous image</a>
            <a class="ppy-switch-enlarge" title="Enlarge">Enlarge</a>
            <a class="ppy-switch-compact" title="Close">Close</a>
            <a class="ppy-next" title="Next image">Next image</a>
          </div>
        </div>
      </div>
    <% end %>
  </div>
</div>

Just a disclaimer, this code demonstrates the basic idea but I use HAML so this ERB may not be exactly correct.

An alternate way that I do this that keeps me from having if/then logic in my views is this:

In Venue.rb:

class Venue
  def photo_state
    venuephotos.count > 0 ? 'with_photos' : 'without_photos'
  end
end

In show.html.erb:

<%= render("venue_#{photo_state}" %>

In _venue_with_photos.html.erb:

<ul class="ppy-imglist">
  <%= render @venue.venuephotos %>
</ul>

In _venue_without_photos.html.erb:

Sorry, no pictures!

In _venuephoto.html.erb

<li class="venue_photo_thumb_container"><%= link_to image_tag ... %></li>

Yes, a bit obsessive, but I like having no code except "render" in my views whenever possible. It's all in whether you like all your code in one file or each piece broken out in easy-to-digest chunks. A preference thing - no real right answer.
