Rails 3.1: accepts_nested_attributes_for and has_one association - won't work?

Question

I\'m trying to use accepts_nested_attributes_for on a has_one association model, and getting absolutely nowhere :-(

I have two models, a user and a location. A user

Answer 1

<%= fields_for(@user.location) do |location_fields| %>

This is your problem. You need to actually "nest" the fields_for inside your form, like this:

<% f.fields_for(@user.location) do |location_fields| -%>
