What's my problem ? named resources

Hi all,

I really have a bad problem. I can't make named resource paths to work.

If I use this: def test_can_show   get :show, :party_id => @bob.id, :id => @address.id   assert_select "\#address_contact_route_#{@address.id}_line1_edit[url=?]",       address_path(@bob, @address, :txt) end

I get a big bang error:   1) Error: test_can_show(AddressContactRoutesControllerTest::PartyWithAddressTest): NoMethodError: You have a nil object when you didn't expect it! The error occurred while evaluating nil.to_sym     /home/francois/src/xlsuite.org/config/../vendor/rails/activerecord/lib/../../activesupport/lib/active_support/core_ext/hash/keys.rb:27:in `symbolize_keys'     /home/francois/src/xlsuite.org/config/../vendor/rails/activerecord/lib/../../activesupport/lib/active_support/inflector.rb:250:in `inject'     /home/francois/src/xlsuite.org/config/../vendor/rails/activerecord/lib/../../activesupport/lib/active_support/core_ext/hash/keys.rb:26:in `each'     /home/francois/src/xlsuite.org/config/../vendor/rails/activerecord/lib/../../activesupport/lib/active_support/core_ext/hash/keys.rb:26:in `inject'     /home/francois/src/xlsuite.org/config/../vendor/rails/activerecord/lib/../../activesupport/lib/active_support/core_ext/hash/keys.rb:26:in `symbolize_keys'     /home/francois/src/xlsuite.org/config/../vendor/rails/actionpack/lib/action_controller/url_rewriter.rb:95:in `rewrite_path'     /home/francois/src/xlsuite.org/config/../vendor/rails/actionpack/lib/action_controller/url_rewriter.rb:69:in `rewrite'     /home/francois/src/xlsuite.org/config/../vendor/rails/actionpack/lib/action_controller/base.rb:522:in `url_for'     (eval):19:in `address_path'     /home/francois/src/xlsuite.org/config/../vendor/rails/actionpack/lib/action_controller/test_process.rb:451:in `send'     /home/francois/src/xlsuite.org/config/../vendor/rails/actionpack/lib/action_controller/test_process.rb:451:in `method_missing'     ./test/functional/address_contact_routes_controller_test.rb:47:in `test_can_show'

My route is properly defined in routes: map.resources :parties, :path_prefix => "/admin" do |parties|   parties.resources :addresses, :controller => "address_contact_routes" end

So, what's my error ? Can anyone spot it ?

Thanks !

hey François (welcome back from vacation),

I've seen that with multiple params to the url helpers - I've solved it by identifying the required params with a symbol.

so address_path(:address_id => @address, @bob, :txt) # is :txt the respond_to format?

this is the general solution, but you may have to add symbols to other params.

cheers, Jodi

Hello Jodi,

Thanks for your response. In fact, I found my solution for a slightly related problem. You can get the gory details on my blog:

http://blog.teksol.info/articles/2007/03/14/named-resources-with-name-prefixes

The solution was to use the correct named route:

  formatted_address_path(@address, @bob, :txt)

is the route to use.

Thanks for your time, Jodi.
