Rails Sub-resources Routing error

Question

I'm having trouble using sub-resources in my Rails application. My goal is to have routes (example application) such as

/people/1/jokes/new /people/1/jokes

The form_for line in my jokes form is turning up the routing error

undefined method `jokes_path'

Note that after you put the jokes resource under people as a sub-resource, the route helpers for the jokes change to have user prefix as follows:

  user_jokes_path # => /people/1/jokes
  new_user_jokes_path # => /people/1/jokes/new
  edit_user_jokes_path # => /poople/1/jokes/:id/edit

Also note that you need to pass user.id to the path as part of the parameters, so if you are using user_jokes_path you need to call it by passing the user object, so if your are storing the user record in @user variable:

<%= link_to 'jokes', user_jokes_path(@user)%>

The best approach is to use rake routes command to see the routes table for your application and find out what it generated
