Map.resource and semi nested resources

Hi,

I have the following in routes.rb

map.resources :districts do |district|
district.resources :circuits, :name_prefix => ‘district_’
end

map.resources :circuits

I want full CRUD for circuits at /circuits but only partial CRUD at
/districts/?/circuits (index and new). This is to avoid too many levels
of nesting (there are several more to come).

I have got this fine for the UI (the links take you around exactly as I
want). But the extra urls are still available.

  1. How do I detect in the controller show if the url is
    /districts/1/circuits/1 which I want to redirect to the un-nested
    version at /circuits/1 ?

  2. How do I know in index of controller whether I am
    /districts/1/circuits (limit to only district 1) or /circuits (list
    all)?

I guess it will be fairly obvious that I am pretty much a rails newbie.
But I have looked in the Agile bk 2nd ed and as many articles on nested
resources as I can find.

Thanks

Dave

  1. If the action was called through the nested route “/districts/1/
    circuits/1”, params[:district_id] would be set. Otherwise it wouldn’t.

  2. same here. look for params[:district].

If params[:district]:
@circuits = Districts.find_by_id(params[:district_id]).ciruits
else
@circuits = Circuit.find(:all)
end

The simplest thing you could do is check for the presence of params
[:district_id] in the circuits controller.
