I'm writing an app where several of the routes should only be accessible from localhost. It looks like this is possible with the new routing system.

This has examples of restricting routes based on IP address, and setting up an IP address blacklist for your routes, but I'm interested in a whitelist with just one IP address.
It would be cool if something like this worked:
get "/posts" => "posts#show", :constraints => {:ip => '127.0.0.1'}
But it didn't. Am I just missing the right syntax?

The :as option creates a named path. You can then call this path in your controllers and views (e.g. redirect_to things_path ). This isn't very useful for the root path (as it already named root ), but is very useful for new routes you add.
Considering the same case, the two terms can be differentiated in a simple way as :member is used when a route has a unique field :id or :slug and :collection is used when there is no unique field required in the route.
Difference between singular resource and resources in Rails routes. So far, we have been using resources to declare a resource. Rails also lets us declare a singular version of it using resource. Rails recommends us to use singular resource when we do not have an identifier.
In Rails, a RESTful route provides a mapping between HTTP verbs, controller actions, and (implicitly) CRUD operations in a database. A single entry in the routing file, such as. map.resources :photos. creates seven different routes in your application: HTTP verb.
you can do this
get "/posts" => "posts#show", :constraints => {:ip => /127.0.0.1/}
or this
constraints(:ip => /127.0.0.1/) do
get "/posts" => "posts#show"
end
