如何在rails中处理这种类型的多级表单

class User< ApplicationRecord
  has_one :address
  accepts_nested_attributes_for :address
end

class UsersController< ApplicationController
  def new
    @user = User.new
    @user.build_address
  end

  def create
    @user = User.new(user_params)
    if @user.save
      redirect_to @user
    else
      render 'new'
    end
  end

  private

  def user_params
    params.require(:user).permit(:name, :email, address_attributes: [:street, :city, :state, :zip])
  end
end

<%= form_with(model: user, local: true) do |form| %>
  <%= form.label :name %>
  <%= form.text_field :name %>

  <%= form.label :email %>
  <%= form.text_field :email %>

  <%= form.fields_for :address do |address_form| %>
    <%= address_form.label :street %>
    <%= address_form.text_field :street %>

    <%= address_form.label :city %>
    <%= address_form.text_field :city %>

    <%= address_form.label :state %>
    <%= address_form.text_field :state %>

    <%= address_form.label :zip %>
    <%= address_form.text_field :zip %>
  <% end %>

  <%= form.submit %>
<% end %>
