Rails 3 - AJAX Response

Rails
1

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

The Response:
