Hi guys, I was thinking aboiut this for a while: If I have nested resource routes, for example /building/1/floor/2/ room/ 3 (building has\_many floors and so on), I have to call the room\_path method like this: room\_path @room.floor.building, @room.floor, @room Isn´t there a better way to handle nested routes with foreign keys, or can I have this method overwritten somewhere?

i don’t understand what’s the exact question here, or how you would like this to be simplyfied, but the correct syntax should be: building\_floor\_room\_path(building\_id, floor\_id, room\_id) (at least for rails edge) ---

But what I meant is, that you have to specify every single item in the path of the url. I think that in 80% of the use cases, nested resources are used to indicate parenting in a tree-like data scheme. Perhaps there could be a new option in the map.resource method that could specify the foreign key to be used when generating a path or url, so you just have to write building\_floor\_room\_path(room\_id) and the values for building\_id and floor\_id would be automatically guessed out of the context.
