File Upload in Selenium on Rails

Hi Friend z,

File Upload in Selenium on Rails.

to make selenium able to fill type="file" input via "type" command:

a) set configuration for mozilla

signed.applets.codebase_principal_support = true

in firefox about:config page

type about:config in addressbar of firefox.

b) add a line in selenium-api.js

netscape.security.PrivilegeManager.enablePrivilege("UniversalFileRead") ;

to \vendor\selenium\core\scripts\selenium-api.js method Selenium.prototype.doType()

It will be definetely useful.

Flexstore on Rails Tutorial

Overview

Flexstore is a traditional
Shopping Cart application. In this tutorial,
we create two modules:

The administration module is an
internal application used to maintain the
product database. You use the administration
module to create, update, and delete products.
The store module is a
customer-facing application. Customers
use the store module to browse and filter
the product catalog.

In the administration module, we use
Rails' simple scaffolding feature to automatically
provide the default infrastructure to list, view,
create, edit, and delete products. In the store
module, we experiment with additional features:

Templates
Filtering using Ajax
Partial Page Templates
Builder Templates
Putting a Flex front-end on top of a
Ruby on Rails application

This tutorial uses a MySQL database. It is assumed
that you already have MySQL up and running.

Create the Flexstore Database

Create a database called "flexstore"
Open a command prompt, navigate to the bin directory of your MySQL Server installation, and type the following command:

mysqladmin -uroot create flexstore

Note: Provide values for userid (-u) and password
(-p) as appropriate if the above values don't
match your installation.
Import the data
- Download flexstore.sql.zip here
- Extract flexstore.sql into the bin
  directory of your MySQL Server installation
- Type the following command to import
  the data in the flexstore database:
  mysql -uroot flexstore < flexstore.sql

Install Ruby and Rails

Install Ruby
- Download the Ruby installer here
- Run the installer. Accept all
  the default settings.
Install Rails
Type the following command in the c:\ruby directory:

gem install rails --remote -- include-dependencies

Create the Administration module

Create the flexstore application
- Create a directory called rails in c:\
- Type the following command in c:\rails:
  rails flexstore
Configure the database for the flexstore application
- Edit database.yml in c:\rails\flexstore\config
- Set the database parameter to
  flexstore in the development,
  test, and production sections
Create a controller for the administration
module
Type the following command in c:\rails\flexstore

ruby script\generate controller Admin
Create a model for the products
Type the following command in c:\rails\flexstore:

ruby script\generate model Product
Modify the admin controller to enable Rails' scaffolding
- Edit admin_controller.rb in c:\rails\flexstore\app\controllers
- Modify the class as follows:
Test the application
- Start the WEBrick web server installed with Rails
  Type the following command in c:\rails\flexstore:
  
  ruby script\server
- Open a browser and access the following URL:
  http://localhost:3000/admin
  
  Rails' scaffolding defined in the
  Admin controller automatically provides
  default actions and views to list, view,
  create, edit and delete products.
  Each of these actions and views can be overwritten.
  We overwrite the default index action in the
  next steps.
Define a custom index action
- Edit admin_controller.rb in c:\rails\flexstore\app\controllers
- Define an index action as follows:
Create the view for the index action
- Create a file name index.rhtml in c:\rails\flexstore\app\views\admin
- Edit index.rhtml as follows:
  
  <html>
  <head>
  <title>Product List</title>
  </head>
  <body>
  
  <table>
  <tr>
  <td>Name</td>
  <td>Price</td>
  </tr>
  
  <% @products.each do |product| %>
  <tr>
  <td><%= link_to product.name, :action => "show", :id => product.id %></td>
  <td align="right"><%= sprintf("$%0.2f", product.price) %></td>
  </tr>
  <% end %>
  </table>
  <p><%= link_to "Create new product", :action => "new" %></p>
  
  </body>
  </html>
Test the application. Open a browser and access the following URL:
http://localhost:3000/admin
Validation
- Edit product.rb in c:\rails\flexstore\app\models
- Modify the class as follows:
Test the application again. Try to add a product without a name or with a non numeric price value.

Create the Store module

Deploy the product images and the flexstore stylesheet
- Download assets.zip here.
- Extract assets.zip in c:\rails\flexstore\public.
Create a controller for the administration module
Type the following command in c:\rails\flexstore:

ruby script\generate controller Store
Define an index action in the Store controller
- Edit store_controller.rb in c:\rails\flexstore\app\controllers
- Define an index action as follows:
Create the view for the index action
- Create a file name index.rhtml in c:\rails\flexstore\app\views\store
- Edit index.rhtml as follows:
  
  <html>
  <head>
  <title>Flexstore on Rails</title>
  <%= stylesheet_link_tag "flexstore", :media => "all" %>
  </head>
  
  <body>
  
  
  <div id="catalog">
  <% for product in @products %>
  
  
  <div class="thumbnail">
  <strong><%= product.name %></strong>
  <img src="<%= product.image %>"/>
  <div>
  <font color="#CC6600"><b><%= sprintf("$%0.2f", product.price) %></b></font>
  <p>
  <%= product.camera==1?'Camera<br />':'' %>
  <%= product.video==1?'Video<br />':'' %>
  <%= product.triband==1?'Triband':'' %>
  </p>
  </div>
  </div>
  
  
  <% end %>
  </div>
  
  
  </body>
  </html>
Test the application
Open a browser and access the following URL:

http://localhost:3000/store

Using Partial Page Templates

In real life, you would probably have to display product thumbnails in different parts of the application. In fact, we will need product thumbnails in the filter module described in the next section. To avoid code duplication, we will isolate the HTML fragment used to render a product thumbnail in a partial page template.

Create a file named _product.rhtml (the partial page template) in c:\rails\flexstore\app\views\store
Open index.rhtml in c:\rails\flexstore\app\views\store
Copy the HTML fragment corresponding to the thumbnail div and paste it in _product.rhtml
In index.rhtml:
- Delete the content of the catalog
  div (both the for loop and the thumbnail div)
- Add the following line of code as
  the sole content of the catalog div:
  <%= render(:partial => "product", :collection => @products) %>
  
  Because we are passing a collection (the list of products) as a parameter, the partial page template will be repeaded for each item in the collection.
Test the application. The product catalog should look the same as in the previous section.
http://localhost:3000/store

Filtering with Ajax

In this section, we provide the product
catalog with filtering capabilities to allow
the user to specify a price range. In response
to the user's selection, the product catalog is
refreshed to display the phones in the selected
price range only. For a better user experience,
the product catalog is refreshed without refreshing
the entire page. This is accomplished using Rails'
built-in support for Ajax.

Add a filter action to the store controller
- Edit store_controller.rb in c:\rails\flexstore\app\controllers
- Define a filter action as follows:
  
  Notice the use of the partial page template
  to return a list of thumbnails for the products
  in the selected price range.
Modify the index view to allow the user
to enter a price range
- Edit index.rhtml in c:\rails\flexstore\app\views\store
- Add the following JavaScript include tag
  immediately after the stylesheet link tag
  <%= javascript_include_tag "prototype" %>
- Add the following html fragment immediately
  before the catalog div.
  
  <div id="left">
  <%= form_remote_tag(:update => "right", :url => {:action => :filter}, :loading => "$('right').innerHTML=''") %>
  Select your price range:<br />
  <br />
  From:<br />
  <%= text_field_tag("from", "0") %>
  <br />
  <br />
  To:<br />
  <%= text_field_tag("to", "1000") %><br />
  
  <br />
  
  <%= submit_tag "Filter" %>
  
  <%= end_form_tag %>
  
  </div>
Change the id of the catalog div to "right". This will allow the stylesheet to position the product catalog to the right of the filter panel.
Test the application
http://localhost:3000/store

Builder Templates

Using Builder templates, you can dynamically
generate XML documents. This provides an
integration point that allows other technologies
to integrate with Rails, and leverage productivity
features of the framwework. In this section,
we create a template that generates an
XML document for the product catalog.

Add a productlist action to the store controller
- Edit store_controller.rb in c:\rails\flexstore\app\controllers
- Define a productlist action as follows:
Create the builder template
- Create a file called productlist.rxml in c:\rails\flexstore\app\views\store
- Edit productlist.rxml as follows:
  xml.list do
  @products.each do |product|
  xml.product do
  xml.name(product.name)
  xml.description(product.name)
  xml.image(product.image)
  xml.camera(product.camera)
  xml.video(product.video)
  xml.triband(product.triband)
  xml.price(product.price, :currency => "USD")
  end
  end
  end
Test the Builder template by accessing the following URL in a browser:
http://localhost:3000/store/productlist

You should see an XML document similar to the one below:

Putting a Flex Front-End on Top of the Rails Application

In this section, we use Flex to improve the
user experience of the product catalog. The user
interface to capture the filtering criteria is
still implemented in HTML.

The Flex-based product list uses the Builder
template created in the previous section to
retrieve the catalog data. Contrary to our
current version, the Flex-based list handles
product filtering at the client-side.
Combined with the use of rich effects and transparency,
this provides the user with smoother transitions
between selections. These transitions implement the
User Interface Design best practise of "visual continuity",
and include visual cues indicating which products
are being filtered out and filtered in.

Define a flex action
- Edit store_controller.rb in c:\rails\flexstore\app\controllers
- Define a flex action as follows:
Deploy catalog.swf (the compiled version
of the Flex-based product catalog).
- Download flexcatalog.zip here.
- Extract flexcatalog.zip in c:\rails\flexstore\public
Notes:
- This application was built using the Flex XML-based framework. You can download the source code here.
- The application was built with Flex 2 beta and requires Flash Player 8.5 beta 2 available here.
First Cut
In our first iteration, the user interface
of the application remains very similiar to the
HTML version. We simply replace the HTML-based
product list with a Flex-based version.
- Create a file named flex.rhtml in c:\rails\flexstore\views\store
- Copy the code below in the flex.rhtml
  
  <html>
  <head>
  <title>Flexstore on Rails</title>
  <%= stylesheet_link_tag "flexstore", :media => "all" %>
  <script type="text/javascript" src="/flex/embedflash.js" ></script>
  <script type="text/javascript" src="/flex/FABridge.js" ></script>
  <script>
  
  function filter() {
  var from = document.getElementById("from").value;
  var to = document.getElementById("to").value;
  var flexApp = FABridge.store.root();
  flexApp.filter(from, to);
  }
  
  </script>
  </head>
  
  <body>
  
  <div id="left">
  Select your price range:<br />
  <br />
  From:<br />
  <input type="text" id="from" value="0"/>
  <br />
  <br />
  To:<br />
  <input type="text" id="to" value="1000"/><br />
  <br />
  <input type="submit" value="Filter" onclick="filter()"/>
  
  </div>
  
  <div id="flex">
  <script>embedFlash("flexApp", "/flex/catalog.swf", 690, 510, "bridgeName=store");</script>
  </div>
  
  </body>
  </html>
- Test the application
  http://localhost:3000/store/flex
Optimizing the user experience
In this second iteration, we optimize the filtering
experience: We use sliders (from the Yahoo UI library)
to select the price range. The Flex-based product list
reacts to the user's selection as the sliders are dragged.
- Install the Yahoo sliders. Download slider.zip here, and unzip the file in c:\rails\flexstore\public.
- Overwrite the content of flex.rhtml with the code below:
  
  <html>
  <head>
  <title>Flexstore on Rails</title>
  <%= stylesheet_link_tag "flexstore", :media => "all" %>
  <script type="text/javascript" src="/flex/embedflash.js" ></script>
  <script type="text/javascript" src="/flex/FABridge.js" ></script>
  <script type="text/javascript" src="/yui/YAHOO.js" ></script>
  <script type="text/javascript" src="/yui/event.js" ></script>
  <script type="text/javascript" src="/yui/dom.js" ></script>
  <script type="text/javascript" src="/yui/dragdrop.js" ></script>
  <script type="text/javascript" src="/yui/slider.js" ></script>
  
  <script type="text/javascript">
  
  var slider1, slider2;
  
  function init() {
  
  document.getElementById("camera").checked = false;
  document.getElementById("video").checked = false;
  document.getElementById("triband").checked = false;
  
  slider1 = YAHOO.widget.Slider.getHorizSlider("slider1", "thumb1", 0, 200, 2);
  slider1.onChange = function(offsetFromStart) {
  var newValue = offsetFromStart * 5;
  document.getElementById("value1").innerHTML = newValue;
  var flexApp = FABridge.store.root();
  flexApp.setMinimum(newValue);
  };
  slider1.onMouseUp = function() {
  var flexApp = FABridge.store.root();
  flexApp.layoutTiles();
  };
  slider2 = YAHOO.widget.Slider.getHorizSlider("slider2", "thumb2", 200, 0, 2);
  slider2.onChange = function(offsetFromStart) {
  var newValue = 1000 + offsetFromStart * 5;
  document.getElementById("value2").innerHTML = newValue;
  var flexApp = FABridge.store.root();
  flexApp.setMaximum(newValue);
  };
  slider2.onMouseUp = function() {
  var flexApp = FABridge.store.root();
  flexApp.layoutTiles();
  };
  }
  
  window.onload = init;
  
  </script>
  
  </head>
  <body style="margin-top:20px; margin-left:20px;">
  
  Select your price range:<br />
