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

`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

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](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.
