Rails Ruby on Rails

Problem 1

  resources 'account', :controller => 'users', :as => 'users' do
    collection do
      post 'reward_all'
    end

    member do
      post 'reward'
    end
  end

yields the error: "missing :action" - referring the apparent need to specify an action for post 'reward'. This seems redundant, as I would change it to

  post 'reward' => :reward

Problem 2

  resources 'account', :controller => 'users', :as => 'users' do
    collection do
      post 'reward_all'
    end

    member do
      post 'reward' => :reward
    end
  end

yields the following - note the incorrect controller and route name on the reward_all collection route
Also, no default named route is provided for the member action

account_reward_all POST   /account/reward_all         {:controller=>"account", :action=>"reward_all"}
                   POST   /account/:id/reward         {:controller=>"users", :action=>"reward"}
                   GET    /account(.:format)          {:controller=>"users", :action=>"index"}
             users POST   /account(.:format)          {:controller=>"users", :action=>"create"}
          new_user GET    /account/new(.:format)      {:controller=>"users", :action=>"new"}
                   GET    /account/:id(.:format)      {:controller=>"users", :action=>"show"}
                   PUT    /account/:id(.:format)      {:controller=>"users", :action=>"update"}
              user DELETE /account/:id(.:format)      {:controller=>"users", :action=>"destroy"}
         edit_user GET    /account/:id/edit(.:format) {:controller=>"users", :action=>"edit"}

Even stranger, by specifying an action on the collection route, it corrects the controller:

  resources 'account', :controller => 'users', :as => 'users' do
    collection do
      post 'reward_all' => :reward_all
    end

    member do
      post 'reward' => :reward, :as => 'reward'
    end
  end

yields

account_reward_all POST   /account/reward_all         {:controller=>"users", :action=>"reward_all"}
       reward_user POST   /account/:id/reward         {:controller=>"users", :action=>"reward"}
                   GET    /account(.:format)          {:controller=>"users", :action=>"index"}
             users POST   /account(.:format)          {:controller=>"users", :action=>"create"}
          new_user GET    /account/new(.:format)      {:controller=>"users", :action=>"new"}
                   GET    /account/:id(.:format)      {:controller=>"users", :action=>"show"}
                   PUT    /account/:id(.:format)      {:controller=>"users", :action=>"update"}
              user DELETE /account/:id(.:format)      {:controller=>"users", :action=>"destroy"}
         edit_user GET    /account/:id/edit(.:format) {:controller=>"users", :action=>"edit"}

Note that the named route is still wrong, but only for the collection action
