Rails 3 Routes - prepend all url paths with set string - ruby-on-rails-3

I've been asked to change the routes on a Rails project such that the routes will only respond to requests where the app name (or other arbitrary string) is the first string after the domain name, e.g.
www.thething.com/appname/users/sign_in instead of www.thething.com/users/sign_in
www.thething.com/appname instead of www.thething.com
www.thething.com/appname/search instead of www.thething.com/search
I've suggested using a subdomain appname.thething.com instead, but the client is quite specific about wanting the URL in the above format.
www.thething.com will be a splash page which will contain a link to www.thething.com/appname, with the intention of adding additional apps/pages in future with new folder names.
Is there an easy way of modifying the routes file so that all routes will get the .../appname prepended to all resources and routes, while being after the domain?

One option is wrap all existing routes in: namespace :appname do ... end, like so:
# config/routes.rb
Appname::Application.routes.draw do
namespace :appname do
# existing routes go here
end
end
I'm not sure if this is the most elegant solution, but it will prepend /appname to all the routes.

Rails 3 optional scope url generation

I have the following defined in my routes.rb
scope '(:subdomain)' do
resource :highscore
end
now I can reach the same resource on these paths
/highscore
/test/highscore
however, when I generate a url using
highscore_path
it will always generate the /highscore path, however, i'd like it to generate a /test/highscore path when inside the test subdomain
i tried manipulating default_url_options or
highscore_path(:subdomain => 'test')
but it always omits the test. How do I work around this, preferrably without having to change all of my urls?
Turns out the specifier 'subdomain' was silly :( replace that with anything else and it'll work!
I've overwritten default_url_options in the application_controller with
def default_url_options
return {:identifier => 'test'}.merge(super)
end

Play framework: Dynamic routing depending on version number

I'm trying to dynamically define a version in the URI routing.
My immidiate ideas were to
a)
I've configured in the application.conf a row stating my current version:
myApp.ver = 0.1
I wan't to use it in the routes file as part of the URI, for example:
GET /myApp/{version}/welcome controller.myApp.Welcome()
The idea is not to pass the version number to the Welcome() method
but to get the version from the application.conf file.
I've searched for defining parameters in the route file but didn't find information that helped me.
b) Another idea was to have a variable in the routes, something like:
CurrentVersion = 0.1
in the routes file and use it in the URI.
How can I solve this? I havn't found an example for this.
Thanks.
If you want to do this for every route, it should be possible to set the application.baseUrl to include your version number. To do this conveniently you can define the version in your application.conf instead of the Build.scala file, as described here.
myApp.name = myApp
myApp.ver = 0.1
application.baseUrl = ${myApp.name}/${myApp.ver}
If you want to do it only for some routes, there doesn't seem to be a simple solution. If you could ignore parameters in routes, I'd say use a regexp parameter and verify it in your global router - unfortunately this doesn't seem possible without passing the parameter to the controller.
So I see two other options:
Hardcode the version number in the routes file and do a search and replace every time it changes.
Create a plugin for the sbt build process and let it replace the version in your routes file.
In Play 1.2.x, in your conf/routes file, add a route like this:
GET /myApp/${play.configuration.getProperty("myApp.ver")}/welcome myApp.Welcome()

Completely custom path with YII?

I have various products with their own set paths. Eg:
electronics/mp3-players/sony-hg122
fitness/devices/gymboss
If want to be able to access URLs in this format. For example:
http://www.mysite.com/fitness/devices/gymboss
http://www.mysite.com/electronics/mp3-players/sony-hg122
My strategy was to override the "init" function of the SiteController in order to catch the paths and then direct it to my own implementation of a render function. However, this doesn't allow me to catch the path.
Am I going about it the wrong way? What would be the correct strategy to do this?
** EDIT **
I figure I have to make use of the URL manager. But how do I dynamically add path formats if they are all custom in a database?
Eskimo's setup is a good solid approach for most Yii systems. However, for yours, I would suggest creating a custom UrlRule to query your database:
http://www.yiiframework.com/doc/guide/1.1/en/topics.url#using-custom-url-rule-classes
Note: the URL rules are parsed on every single Yii request, so be careful in there. If you aren't efficient, you can rapidly slow down your site. By default rules are cached (if you have a cache setup), but I don't know if that applies to dynamic DB rules (I would think not).
In your URL manager (protected/config/main.php), Set urlFormat to path (and toptionally set showScriptName to false (this hides the index.php part of the URL))
'urlManager' => array(
'urlFormat' => 'path',
'showScriptName'=>false,
Next, in your rules, you could setup something like:
catalogue/<category_url:.+>/<product_url:.+> => product/view,
So what this does is route and request with a structure like catalogue/electronics/ipods to the ProductController actionView. You can then access the category_url and product_url portions of the URL like so:
$_GET['category_url'];
$_GET['product_url'];
How this rule works is, any URL which starts with the word catalogue (directly after your domain name) which is followed by another word (category_url), and another word (product_url), will be directed to that controller/action.
You will notice that in my example I am preceding the category and product with the word catalogue. Obviously you could replace this with whatever you prefer or leave it out all together. The reason I have put it in is, consider the following URL:
http://mywebsite.com/site/about
If you left out the 'catalogue' portion of the URL and defined your rule only as:
<category_url:.+>/<product_url:.+> => product/view,
the URL Manager would see the site portion of the URL as the category_url value, and the about portion as the product_url. To prevent this you can either have the catalogue protion of the URL, or define rules for the non catalogue pages (ie; define a rule for site/about)
Rules are interpreted top to bottom, and only the first rule is matched. Obviously you can add as many rules as you need for as many different URL structures as you need.
I hope this gets you on the right path, feel free to comment with any questions or clarifications you need

Rails route to catch everything except assets

I'm trying to allow admin to create pages on the root path. So far i have:
get ':path' => "pages#show" ,:as =>:page, :path => /[^\.]+/
Basically i'm trying to ignore all paths with a dot in them (like .png). This does not seem to work as everything is rejected (i only want things in the public directory to be rejected, like fonts, icons, images..)
Thanks
As I explained in my comment above, "everything in public is directly rendered by the webserver" is NOT true if the desired asset does not exist. This will result in your catch-all route catching this undesired side-effect. This could cause a number of problems, as I explained. So, A specific catch-all route is needed to compensate for this:
get ':path' => "pages#show", :as => :page, :constraints => lambda{|req| req.path !~ /\.(png|jpg|js|css)$/ }
you can manipulate the regex how ever you see fit as my goal was just to get you on the right track by showing you that you can pass a block to the :constraints option. Also, I didn't just test req.format because that would exclude requests with header information for js format and would result in the catch all not working for these types of requests (not a usual case for a catch-all, but that's irrelevant). By using req.path instead, the header info is left intact/working and the path dictates whether or not this request is caught by this route.
I hope this helps you.
TESTING:
To test to see if your catch-all is actually catching what you want and not additional public resources, follow these steps. First put a debugger in your catch-all action, in your PagesController. Then make a request to a public file png/js/css file that DOES exist, like localhost:3000/images/example_image.png, and it should not hit your catch-all, as usual. Now, change the path to an image that doesn't exist, localhost:3000/images/no_image.png . If the request does not hit your debugger, your catch-all is not catching the image file request, and your ALL SET. If the request does hit your debugger, that means your catch-all is catching the image file request which means you need to revise your constraints in your catch-all.
By default dynamic segments don’t accept dots – this is because the
dot is used as a separator for formatted routes. If you need to use a
dot within a dynamic segment add a constraint which overrides this –
for example :id => /[^/]+/ allows anything except a slash.

So just removing the condition works. There might be another better solution to this problem though.

tradeoff routes and views rails 3

here it's routes.db
resources :licenses do
resources :sublicenses do
resources :time_licenses
end
end
Then there is a client application that calls time_licenses_controller for creating new time_licenses, the controller responds with a json file, but i don't need to show any view.
Somewhere else instead i need to show to the client an index file including all time_licenses for every sublicense.
That's the path
license/:id/sublilicense/:id/time_lincenses
Now i have a problem with the routes. When i call the create on time_licenses_controller i get this error:
No route matches "/time_licenses.js"
that i can solve changing the routes.db file like this
resources :time_licenses
resources :licenses do
resources :sublicenses
end
but in that case i get the same error linking the index view.
What do you suggest me? Do i have to create two different controllers?
Since you are using nested resources, you will always need to specify license and sublicense while specifying the path to timelicense.
Your path helpers will be:
license_sublicense_timelicense_path(#license, #sublicense, #timelicense) and so on
You can get the path names for the timelicense by
rake routes
Refer rails guides - nested resources for any doubts.
