Named Routes

When you add a custom route, make it a named route so you have url helper methods to easily link to that new route. See episode for details.

# routes.rb
map.resources :projects
map.task_archive 'tasks/:year/:month', :controller => 'tasks', :action => 'archive'
map.home '', :controller => 'projects', :action => 'index'

<!-- projects/index.rhtml -->
<ul>
<% for project in @projects %>
  <li>
    <%= link_to project.name, project_path(project) %>
    | <%= link_to "Edit", edit_project_path(project) %>
    | <%= link_to "Destroy", project_path(project), :method => :delete %>
  </li>
<% end %>
</ul>

Great episode as always!

If I'm not mistaken, you've used this kind of a named route ('resources') behind the scenes in episode 21 as well....(REST).

Gr,

@Jermaine, yep, I've been using this technique all over the place in previous episodes. Thought it was about time I explained it. :)

For some reason I get a NameError whenever I try to use path but url works great. Is there any reason to believe that path is deprecated or replaced with something else? Or is there something else we need to set somewhere for this to work right?

@Gary, what version of Rails are you using? It may require 1.2 but I"m not sure.

Great stuff!

Btw, Errtheblog.com has a helpful rake task to print out all of your named routes, here:

http://require.errtheblog.com/projects/browser/dugg/lib/tasks/err.rake?format=raw

So whenever I need to know what named routes are available for a resource, I just do:

rake routes | grep post
