Dynamic Routing

Rails
1

Hi,
I want to have the following URL structure
/music
/movies
etc. for categories of the site.

/about
/help
etc. for static pages.

Both types auf URLs should be generated dynamically.

But how do I route them?

map.connect ‘/:category/’, :controller=>‘magazine’, :action=>‘index’,
:rubrik => // #should be generated from database, but how?

map.connect ‘/:page/’, :controller=>‘magazine’, :action=>‘page’,
:page => /[(help)|(about)]/ #but should also be generated
dynamically

Thanks.

Sounds interesting.
But I’ve already found a simpler solution, without making a plugin:

map.connect ‘/’, :controller =>‘magazin’, :action=>‘index’
map.connect ‘/:rubrik/’, :controller=>‘magazin’, :action=>‘index’,
:rubrik => Regexp.new(Category.find(:all).collect {|o|
“(#{o.name})”}.join(‘|’).downcase)

map.connect ‘/:page/’, :controller=>‘magazin’, :action=>‘page’,
:page => Regexp.new(Page.find(:all).collect {|o|
“(#{o.title})”}.join(‘|’).downcase)

map.slug ‘/:slug/’, :controller =>‘magazin’, :action=>‘artikel’

You can create an Regexp from an array. Great. But maybe slow?

nice regards,
ernst

I run into one article when looking for a way to implement routes from
database and multi-language URL’s. It could be of interest to you, I
didn’t try it yet:

Now you just read a *param in your controller, and render the appropriate
response.

I think you probably want :login, rather than *login. *login gives you
a route glob, which might contain any number of fields. They’ll be
delivered to the action in an array (params[:login]), whereas with
:login you’ve got just one wildcard field, which will be delivered as
a string.

There’s a bit of a potential problem with this route, though. If
someone has a login name that’s the same as a controller, you might be
in trouble:

ActionController::Routing::Routes.recognize_path(“/dblack”)
=> {:login=>“dblack”, :controller=>“account”, :action=>“home_page”}
ActionController::Routing::Routes.recognize_path(“/questions”)
=> {:controller=>“questions”, :action=>“index”}

If someone happens to sign up as “questions”, their home page link
won’t work. So it might be better to do something like:

map.connect ‘home/:login’, :controller => “account”, :action =>
“home_page”

which gives you:

ActionController::Routing::Routes.recognize_path(“/home/david”)
=> {:login=>“david”, :controller=>“account”, :action=>“home_page”}
ActionController::Routing::Routes.recognize_path(“/home/questions”)
=> {:login=>“questions”, :controller=>“account”, :action=>“home_page”}

This provides a custom homepage for any user: site.com/my_name

map.connect ‘:controller/:action/:id’
map.connect ‘*login’, :controller => ‘account’, :action => ‘home_page’

The trick is that param[:login] arrives in your controller.

I suspect I should have tested my system with this:

assert_routing '/mr_smith',
               :controller => 'account',
               :action => 'home_page',
               :login => 'mr_smith'

Now you just read a *param in your controller, and render the
appropriate
response.

Do you reload routes when category or page is added in database?

I didn’t think of it, but now as you say it I think I better should :wink:
