Rails route lets :id be a domain name

logankoester (Logan Koester) — Wed, 01 Aug 2007 02:51:20 GMT

// Named route for an id that contains . characters, such as a domain name
// eg: http://myapp/domains/foobar.com



map.domain 'domains/:id', :controller => 'domains', :action => 'show', :requirements => { :id => /[a-zA-Z0-9\-\.]+/ }

exception_logger route

map.exceptions '/logged_exceptions/:action/:id', :controller => 'logged_exceptions', :action => 'index', :id => nil

Named Routing in Rails (getting rid of the ids)

monkeymagic () — Mon, 27 Feb 2006 20:04:43 GMT

Lifted from Semergence
(http://www.semergence.com/archives/2005/12/01/10/02/32/)

In config/routes.rb:





map.project ‘project/:projtitle’ :controller => ‘project’, :action => ’show’

In app/controllers/project_controller.rb:



   def show

     @project = Project.find(:first,

                             :conditions => [’title = ?’,params[:projtitle]])

     …

   end

Or something like that. Assuming your project titles are unique. Then
you can also use project_url (since you have map.project in routes.rb)
for urls in your views, e.g.



   <% for project in @projects %>

   <%= link_to project.title,

               project_url(:projtitle => project.title) %>

    …

   <% end %>

Alternative Default Routes

rtomayko (Ryan Tomayko) — Wed, 28 Sep 2005 00:18:49 GMT

I prefer :controller/:id/:action formatted URIs to :controller/:action/:id. For instance, "people/56/edit" to "people/edit/56". This is a simple matter of taste and has no real benefits other than being a bit more intuitive to certain brains.

It's also a bit harder to do than you might expect. You need to replace the default :controller/:action/:id route with the following:



map.connect ':controller/:action', 

            :requirements => { :action => /\D+/ }



map.connect ':controller/:id/:action',

            :action => 'show',

            :requirements => { :id => /\d+/ }

This will result in the following URIs for the basic set of CRUD actions generated by default:



/people/         (:action => 'index')

/people/new

/people/create

/people/56/      (:action => 'show' by default)

/people/56/edit

/people/56/remove

/people/56/update

You could argue that the default route setup in Rails is a correct default because it's a bit more simple to apply across all cases.

Create spiffy myhost/[keyword] type routing

jmoses (jon) — Tue, 02 Aug 2005 05:24:57 GMT

Except that I can't figure out how to do it in routes. This is what I found.

In *config/routes/rb*, as the last route add:



 map.connect '*path', :controller => 'application', :action => 'handle_unrecog'

In *app/controllers/application.rb*, put this:



 def handle_unrecog

  #do something here, the path info is in the @params value

 end

One of my uses for this is for a del.icio.us type user viewing. IE: _http://del.icio.us/[user]_ but having it only valid for users.

I'd do something like this:



 def handle_unrec

  uname = @params['path'][0] #first part of the path

  user = User.find_by_login( uname )

  if user

   return render :controller => "user", :action => "show", :id => user

  else

   return render :controller => "user", :action => "notfound"

  end

 end

Yay!

Snippets' routes

peter (Peter Cooperx) — Fri, 08 Apr 2005 01:46:38 GMT

These routes allow URLs like tags/whatever/whatever/whatever to put 'whatever', 'whatever', and 'whatever' into the @params[:tags] array, etc.

map.connect '', :controller => "posts", :action => "index"

map.connect 'tags/*tags', :controller => 'tag', :action => 'show'

map.connect 'user/:user', :controller => 'user', :action => 'show'

map.connect 'user/:user/tags/*tags', :controller => 'tag', :action => 'show'

Pretty archive URLs in Typo with Routes

peter (Peter Cooperx) — Sun, 03 Apr 2005 16:41:16 GMT

Tobi posted this as a new URL scheme for Typo.

# allow neat perma urls

map.connect 'articles/:year/:month/:day', :controller  => 'articles', 

     :action => 'find_by_date', 

     :year => /\d{4}/, :day => nil, :month => nil

map.connect 'articles/:year/:month/:day/:title', :controller  => 'articles', 

     :action => 'permalink', :year => /\d{4}/
