find(params[:id])
@layouts = Layout.find :all, :order => 'name'
end
def update
@path = Path.find(params[:id])
if @path.update_attributes(params[:path])
flash[:notice] = 'Path was successfully updated.'
redirect_to :action => 'show', :id => @path
else
@layouts = Layout.find :all, :order => 'name'
render :action => 'edit'
end
end
This is all you need to do to get the Path controller working as you want it to. The next step
is to change the views, and as it happens, they don??™t need much editing either. First of all, the
list view needs to be changed a little bit:

Listing paths

CHAPTER 7 ?–  A RAILS CMS 128





<% for path in @paths %>






<% end %>

Name	Path
<%= link_to h(path.name), { :action => 'edit', :id => path }%>	<%= h path.path%>		<%= link_to 'Destroy', { :action => 'destroy', :id => path }, :confirm => 'Are you sure?', :post => true %>

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


<%= link_to 'New path', :action => 'new' %>
Second, the form for new and edit also needs to be changed.
