When testing I get this code I get the following error:

test “should update proveedor” do  
put :update, :id =\> proveedores(:iberdrola).to\_param, :proveedor =\>  
{:fax =\> ‘943456578’}  
assert\_redirected\_to proveedor\_path(assigns(:proveedor))  
end

1. Error:  
test\_should\_update\_proveedor(ProveedoresControllerTest):  
ActionController::RoutingError: proveedor\_url failed to generate from  
{:action=\>“show”, :id=\>nil, :controller=\>“proveedo  
res”}, expected: {:action=\>“show”, :controller=\>“proveedores”}, diff:  
{:id=\>nil}  
(eval):16:in `proveedor_path' /test/functional/proveedores_controller_test.rb:37:in`test\_should\_update\_proveedor’

I have searched the web and I know that the problem is that  
assigns(:proveedor) are not putting the param id that is necessary to  
generate the correct URL, but why? Any idea?

Hi Juan K.

```
 What is in your update action? Can you paste it? I think the id for 

```

proveedor is not setting in update…So the value of id is getting as  
nil. Check assert assigns(:proveedor) also

Yes. I found the problem. The problem was that the controller didn’t  
create the proveedor properly and the id were not create properly then.

Thanks!
