As far as your link_to usage, yes. They’re the same. The named route is easier to maintain codewise but a little slower [at least in the olden days] than writing it out by hand like you do in the second example. The difference between those last map.connect and map.details is 1. map.details creates a named route where map.connect doesn’t and 2. You’ll need to add the mapping “nj/:id” to map.detail.
