i have defined the routes.rb file as

map.root :controller =\> “site”, :action =\> “home”  
map.connect ‘:controller/:action/:id’  
map.connect ‘:controller/:action/:id.:format’  
map.resources :categories, :controller =\> “categories”,:action =\>  
“create”

or i have tried it as in another way

ActionController::Routing::Routes.draw do |map|  
map.resources :categories  
end  
map.root :controller =\> “site”, :action =\> “home”  
map.connect ‘:controller/:action/:id’  
map.connect ‘:controller/:action/:id.:format’

when i try either of this now…i m not getting a undefined category\_path  
anymore…but now i m getting a different error…

Error:  
test\_should\_create\_category(CategoriesControllerTest):  
ActionController::RoutingError: category\_url failed to generate from

rake routes

```
                   / 

```

Hi Sanjana

It is

ActionController::Routing::Routes.draw do |map|  
map.root :controller =\> “site”, :action =\> “home”  
map.resources :categories  
map.connect ‘:controller/:action/:id’  
map.connect ‘:controller/:action/:id.:format’  
end

> map.connect ‘:controller/:action/:id’  
> map.connect ‘:controller/:action/:id.:format’

This can be avoided if you define all ypur routes in routes.r properly

```
This shows the show action does not getting the id..From your first 

```

post, is  
assigns(:category) has value?
