Question

I have a Project model that has_many :workers. In routes.rb, workers are a nested resource for projects:

    resources :projects do
            resources :workers
    end

I would like to make it so that when a user goes to the path

'/project_name'

they’re routed to the show action for the project with that name.

And when a user goes to the path

'/project_name/workers/worker_id'

they’re routed to the show action for the worker with that id.

I would also like to make it so that project_worker_path(@project, @worker) routes to

'/project_name/workers/worker_id'

I’d appreciate any help.

Answer 1

Haven’t tested it, but I believe the following will work.

In routes.rb:

resources :projects, :path => '/' do
  resources :workers
end

In project.rb:

def to_param
  name
end

In projects_controller.rb:

@project = Project.find_by_name(params[:id])

In workers_controller.rb:

@project = Project.find_by_name(params[:project_id])

Basically, to_param is used to generate the url, and :path => '/' tells it that you don’t want anything to come before the parameter. This will also map the root path to projects#index if that’s what you want it to do. You can turn that part off by passing :except => :index to resources.
