Once again, the controller is finished, and you should go ahead and work on the views.
First of all, open up the list.rhtml file and edit it to look something like this:

Listing styles








<% for style in @styles %>





<% end %>
NameType
<%=link_to h(style.name), admin_url(
:controller => params[:controller],:action => 'edit',
:id => style)%>		<%=h style.style_type.name %><%= link_to 'Destroy', admin_url(
:controller => params[:controller], :action => 'destroy',
:id => style), :confirm => 'Are you sure?',
:post => true if style.stylings.empty?%>

<%= link_to 'Previous page', { :page =>
@style_pages.current.previous } if @style_pages.current.previous %>
<%= link_to 'Next page', { :page =>
@style_pages.current.next } if @style_pages.current.next %>


<%= link_to 'Create new style', admin_url(:controller =>
params[:controller],:action => 'new') %>
As you can see, you??™ve used the admin_url helper again here. Also notice that you only
show the destroy link if the style has no associated stylings. That means you can only remove
a style that isn??™t used by anyone.
The _form.rhtml file doesn??™t need to change so much:
<%= error_messages_for 'style' %>



<%= text_field 'style', 'name' %>


CHAPTER 7 ?–  A RAILS CMS 131



<%= text_area 'style', 'data' %>




<%= select 'style', 'style_type_id',
@style_types.
