Validation doesn't work (newbie in Rails)

Rails
1

Hi guys,

I am newbie in Rails world and I am using the Agile Web D. with
Rails book to learn Rails.

I am trying to create a simple example using validation, actually only
one field on the User Interface and this field uses the
validates_presence_of validation.

Although this is a simple example, it doesn’t work for me. Below
following the source code of the VIEW, CONTROLLER, MODEL.

View (index.html.erb)

Products#index

<%= error_messages_for :product %> <% form_for :product,:url => {:action => :create} do |form| %> Name: <%= form.text_field :name, :size => 30 %>
<%= submit_tag %> <% end %>

Controller (products_controller.rb)
class ProductsController < ApplicationController

def index
end

def create
@product = Products.new(params[:product])
end
end

Model (products.rb)
class Products < ActiveRecord::Base
validates_presence_of :name, :message => “This is a required field”
end

As you can see, it is very simple. However it is not working properly.
If you click “Submit” on index page, even if the “name” field is empty,
the create.html.erb is called.

Does anyone could help me?

Thanks in advice.

The only problem I can see off hand is that you might need to change
your create action:

def create
@product = Products.new(params[:product])
if @product.save
redirect_to :action => :list
else
render :action => :index
end
end
