Question

I would like to do something like github has with nested urls, and like How do I route user profile URLs to skip the controller? but not really sure how to go on with it.

For example, looking at a commit they have: :user/:repo/commit/:sha , with the controller being commit. How would I replicate this type of nested resource?

thank you :)

Answer 1

If commit is a RESTful controller that uses :sha instead of an id to find records. You could do this instead:

map.resource :commits, :path_prefix =>  :user/:repo , :as =>  commit

It will create the standard RESTful routes that look like http://yoursite.tld/:user/:repo/commit/:id

Again, if you ll never be translating the id portion in the url to a commit id, then there s no reason you can t use it as a :sha value.

example:

class CommitController < ApplicationController
  def show
    @commit = Commit.find(:first, :conditions => {:sha => params[:id]})
  end
  ...
end

You may also want to over ride to_param in the commit model to return the sha value.

class Commt < ActiveRecord::Base
  ...
  def to_param
    sha
  end
end

So that now link_to commit_url(@commit, :user => current_user, :repo => @repo) will provide a url that matches your scheme.

Answer 2

How about

map.connect  :user/:repo/commit/:sha , :action => :index

Or use map.resource instead of map.connect if you need a RESTful route.

In the controller, the URL information can be retrieved from params, for example params[:user] returns the username.

Answer 3

You can name your routes as you like, and specify which controllers and actions you d like to use them with.

For example, you might have:

map.connect  :user/:repo/commit/:sha , :controller =>  transactions , :action =>  commit

This would send the request to the commit method in transactions controller.

The other variables can then be accessed in your controller using params:

@user = User.find(params[:user])
@repo = Repo.find(params[:repo])
