如何在rails 6中只更新current_user的嵌套表单属性？

class User < ApplicationRecord
  has_one :profile
  accepts_nested_attributes_for :profile
end

class ApplicationController < ActionController::Base
  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:profile_attributes => [:attribute1, :attribute2]])
    devise_parameter_sanitizer.permit(:account_update, keys: [:profile_attributes => [:attribute1, :attribute2]])
  end
end

<%= form_for(current_user) do |f| %>
  <%= f.fields_for :profile do |profile_fields| %>
    <%= profile_fields.text_field :attribute1 %>
    <%= profile_fields.text_field :attribute2 %>
  <% end %>
  <%= f.submit "Update" %>
<% end %>
