Problem with single form and two models

Rails
1

Hello everyone
Just started to learn ROR.Does anyone have an idea on how to store
fields in two tables using a single form?
I wish to store the registration details in ‘users’ table and the
langauges selected by the user in another table user_language with each
row for one language selected(fields in the user_language table is
user_id and language_id where user_id is the id of the user trying to
register ie there may be more than one languages for a single user)
My view is like the following
<% form_for :user do |f| %>

Enter Name : <%= f.text_field :name %> Enter Username : <%= f.text_field :username %> Enter Password : <%= f.password_field :password %> Address : <%= f.text_field :address %> Select Gender : <%= radio_button("user", "gender", "1") %>Male <%= radio_button("user", "gender", "2") %>Female <%= radio_button("user", "gender", "3") %>Not Applicable Select Languages Known : <% for language in @languages %> 
   <%= language.language %> <%=

check_box_tag(“user_language[language_id][]”,"#{language.id}") %>
<% end %>

  </td>
  </tr>
Select country : Select Country <%= options_from_collection_for_select( Country.find(:all), "id", "name") %> Select State :
<%= select("user", "state_id", State.find(:all).collect{ |c| [ c.state, c.id] }, {:prompt => 'Select State'},{:onchange=>'display_msg();'}) %> 
    <%= observe_field("user[country_id]",
                :frequency => 0.50,
                :update => "user_state_id",
                :url => {:action => :load_states},
                :with => "'country_id='+value")
            %>
            </div>
    </td>
  </tr>
<%= f.submit "Register" ,{:onclick=>"display_msg(document.getElementById('user_name').value)" }%> <%= f.submit "List Users" %> <% end %>

Controller contains
def create
@languages = Language.find(:all)
if request.post? and params[:commit] == “Register”
@user = User.new(params[:user])

@user.save
@user.user_language = User_Language.new(params[:user_language])
redirect_to :action => 'list_users'

end
when trying an error occurs . Pls help!
