I like HighCharts and used it for one of our project. I wanted to use HighCharts in Rhomobile mobile applications and thought I would give it a whirl.
You can find the sample I tried that would include

• Stacked bar chart

We wanted to consume simple SOAP based web services from the iPhone, Android applications using RhoMobile framework. We dont want to use Savon as it got too much dependency to become rhodes-ruby extension.
Just thought lets write the raw soap client without using SOAP gems. Rhodes already support net-http and rexml(rhoxml) for such tasks.

This is a small blog about applying authorization to an application and how to write unit,functional and integration tests for the application in the end, so the first blog I will cover how to do simple authorization in rails and in the second part of the application I will write the complete test cases for this application.

The scenario: Application – Managing Contents
(list of actions available are index,show,new,create,edit,update and destroy)
The application has three roles Admin,Publisher and member

Admin – has access to all the actions.
Publisher – has access to everything except destroy action.
member – can only access index page and show page.

There are so many plugins available outside for implementing this Authorization. I decided to do it on my own since this is a simple authorization application, but if you want to go for complex scenarios I suggest you check this link

Ok enough talk, let’s digg inside the code.

This application is completely about Authorization, I provided a simple authentication but, for providing proper authentication the plugins I suggest are auth_logic or restful_authentication(plugins) or you can write your own authentication code. Anyway let’s go with the code.

In this application I created login_controller for authentication, it’s a simple form with one textfield which will expect you to enter the user type(member,publisher or admin).

To access any action first of all the user must be a registered user that is member, Admin can access every action of the application and Publisher can do everything except deleting the content.

Let me show the code for authentication

So I created a scaffold for content application.

So once you successfully logged in the the role will be saved in a session.

So the code is self explanatory, you can move this to application controller if you want to applay this authorization than to more than one controller.

admin?.publisher? are can be used a helpers in the views to hide the links for users that are not supposed to show

for example:

<% if publisher? || admin? %>
    <td><%= link_to 'Edit', edit_content_path(content) %></td>
    <% end %>
    <% if admin?
    <td><%= link_to 'Destroy', content, :confirm => 'Are you sure?', :method => :delete %></td>
    <% end %>

So this is the simple authorization I provide for the system, if your system is complex there are plugins available for authorization you can check this blog post for that

Ok. If you have already read the Devise gem wiki, you wouldn’t be seeing this, if not here is the simple way to do it.
