Ruby on Rails

Hi,

I'm trying to understand some code in a book I'm reading and was hoping
someone could tell me if I have understood it correctly.

There are two models, an employee model and a department model. A
department has_many :employees and an employee belongs_to :department.

Here's a snippet of code from the form to edit an existing employee:

<% fields_for( @employee.department) do |department_f| %>
<p>
<%= department_f.label :name,"Department name" %><br />
<%= department_f.text_field :name %>
</p>
<% end %>

The form is submitted to the update action of 'employees_controller.rb',
where there is the following code:

if @employee.update_attributes(params[:employee]) &&
@employee.department.update_attributes(params[:department])
... employee successfully updated ...
end

My question is about the line
"@employee.department.update_attributes(params[:department])"

Is it correct to say that this code updates the attributes (in this case
"name") of the Department object that is linked (via the "has_many" and
"belongs_to" relationship) to the Employee object currently being
edited?
