Rails - Jun 2010 - Rails 3 - AJAX Response

Hi,

I need help with some AJAX in rails 3.

So basically, I have a select option in my index page for my User
model. This select option is a form that modifies the user''s type. The
" :remote => true " works and the type is changed when hit the
submit
button. But, nothing happens in the browser. The user is updated.

I''m actually not sure where to put either my JS / RJS file (
I''ve
tried both, but neither do anything.  )

So here''s my code:

The form:
===   <%= form_for(@user, :remote => true) do |f|  %>
        <%= f.select("type_id" , Type.all.collect{ |t|
[t.name,t.id] } ) %> #TYPE is another model. User belongs_to Type
        <%= f.submit "Save"  %>
    <% end  %>
===

The model:
===class UsersController < ApplicationController
  skip_before_filter :authorize, :only => [:new, :create]
  # GET /users
  # GET /users.xml
  def index
    @users = User.all

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @users }
    end
  end

  # GET /users/1
  # GET /users/1.xml
  def show
    @user = User.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @user }
    end
  end

  # GET /users/new
  # GET /users/new.xml
  def new
    @user = User.new

    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @user }
    end
  end

  # GET /users/1/edit
  def edit
    @user = User.find(params[:id])
    if params[:change_type]
        change_type
    end
  end

  # POST /users
  # POST /users.xml
  def create
    @user = User.new(params[:user])

    respond_to do |format|
      if @user.save
        format.html { redirect_to(@user, :notice => ''User was
successfully created.'') }
        format.xml  { render :xml => @user, :status
=> :created, :location => @user }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @user.errors, :status
=> :unprocessable_entity }
      end
    end
  end

  # PUT /users/1
  # PUT /users/1.xml
  def update

    @user = User.find(params[:id])

    unless params[:user][:type_id]

        @user = User.find(params[:id])

        respond_to do |format|
          if @user.update_attributes(params[:user])
            format.html { redirect_to(@user, :notice => ''User was
successfully updated.'') }
            format.js
            format.xml  { head :ok }
          else
            format.html { render :action => "edit" }
            format.js
            format.xml  { render :xml => @user.errors, :status
=> :unprocessable_entity }
          end
        end
    else
      respond_to do |format|
        if @user.update_attribute("type",
Type.find_by_id( params[:user][:type_id] ) )
          format.js{ head:ok}
        else
          format.js {head:ok}
        end
      end

    end

  end


  def change_type
    unless params[:change_type_value]
      if   @user.category == 5
          @user.category = 0
      else
        @user.category = 5
      end


      respond_to do |format|
        if @user.save
          format.html { redirect_to( users_path, :notice =>
"Sucessfully changed " + @user.name.titleize + "''s
category" ) }
          format.js
        else
          format.html { redirect_to( users_path, :notice => "Failed to
change " + @user.name.titleize + "''s category" ) }
        end
      end
    end
  end

  # DELETE /users/1
  # DELETE /users/1.xml
  def destroy
    @user = User.find(params[:id])
    @user.destroy

    respond_to do |format|
      format.html { redirect_to(users_url) }
      format.xml  { head :ok }
    end
  end


end
