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).

Congratulations,
this screencast is fabulous.

@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

That's extremely useful, thanks Geoff!

For those not sure how to install it, add the .rake file to your lib/tasks directory.

REST,yes,it's good for me .
thanks.
你们这样的同志是值得尊敬的！

I finally understood what was the problem with path not working. I had updated the gems but hadn't updated the version number in environment.rb.

Once I updated it everything worked fine.

Hi Ryan,

One thing I noticed was that when

/page/1;edit
/page/edit/1

Sup Ryan,

When you did:

map.task_archive 'tasks/:year/:month', :controller => 'tasks', :action => 'archive'

Doesnt this conflict with the standard routing:

tasks/show/2

Is it the case that human reason excludes the possibility of the phenomena, or is the real question whether the phenomena can be treated like the Categories?
