Some ideas on a small framework. Yet another web framework.

gistfile1.rb

class Lists < App
  authenticate { AuthenticationService.authenticate(session) } # just an example, it checks for true or false only
  authorize { current_user.role? :admin }, :for => :create, :update # same here
  
  all { List.all } # :get /lists

  # the param name should always be class.name.singularize
  one { List.find(params[:list]) } # :get /lists/:id
  instance { List.new(params[:list]) }

  to_update { list.update_attributes(params[:list]) }
  to_destroy { list.destroy }
  to_save { list.save }

  # If you want to set an action for this resource only.
  get :search do
    List.search(params[:query])
  end
end

class Tasks < App
  parent Lists # this invokes Lists#find and sets an ivar before finding tasks

  all { list.tasks.all } # :get /lists/:id/tasks
  one { list.tasks.find(params[:task]) } # :get /lists/:id/tasks/:id
  instance { list.tasks.new(params[:task]) }

  to_update { task.update_attributes(params[:task]) }
  to_destroy { task.destroy }
  to_save { task.save }
end

class Search
  all { SearchService.search(params[:resource], params[:query]) } # :get /search
end
