# routes.rb

# map.resources :entries map.resource :home

in entries show view  
\<%= link\_to ‘ca’, home\_path(2) %\>

it has a error:  
You have a nil object when you didn’t expect it!  
The error occurred while evaluating nil.to\_sym

so, what’s going go here?

With a singular resource no id is required for show.

\<%= link\_to ‘ca’, home\_path %\>

If you need to pass parameters a hash will work.

\<%= link\_to ‘ca’, home\_path(:id =\> 2) %\>
