Foreign Key Dropdown in Scaffold Rails 3 Views

Question

I created 2 models using scaffolding with Rails 3. The models are Locations and Jobs and each job has a location.

I created the required reference calls in the scaffold generation code but when I look at the view to create a new job, all I see is a textbox where I should add the location_id.

How can I get that to be a dropdown instead for a better user experience?

Imagine, that you have got title for each location

<%= f.collection_select :location_id, Location.all, :id, :title %>

I think this should be `:location_id` otherwise you get an `undefined local variable or method` error. – user000001 Oct 15 '14 at 09:32
