Overview of this book

The four Rhomobile products – Rhodes, Rhosync, RhoHub, and Rhogallery – provide a complete toolkit for creating a mobile application. Rhomobile is cross-platform and so allows you to build your application for many different types of smartphone – including iPhone and Blackberry – just with a single codebase. This makes it the most preferred and quickest way of developing mobile apps. As you create a native Rhomobile application, you can use the built-in device features such as GPS, Push, and Camera, all with offline capabilities.Rhomobile Beginner's Guide is filled with practical examples to help you to create a mobile application from scratch. You can choose on which operating system to build, as well as for which smartphone to develop your application, giving you the freedom to create a customized mobile application quickly and easily.Once you have learned how to install Rhomobile on Windows, Mac, or Linux, you will create a simple application, which will be used to explore the products of Rhomobile one by one. Things really get going when you write unit test cases for your application before deploying it to the server and making builds for your chosen Smartphone. You will learn about the different aspects of Rhomobile, starting with Rhodes 3, which helps you to build a native mobile application. Rhosync 2.1 carries out the offline device capabilities and RhoHub deploys the code on the server and creates a build for the different smartphones.

Time for action – Connecting the Rhodes application to RhoSync


As we have seen that RhoSync is a separate application hosted on some servers and the Rhodes application is a different one installed on the mobile client. Rhodes and RhoSync applications will interact with each other using the https protocol. RhoSync application runs on port 9292 unless specified.

Open rhoconfig.txt in your Rhodes application and add specify the URL for the RhoSync server:

syncserver = 'http://localhost:9292/application'

Note

If you are developing your app for Android then you have to give the IP address instead of localhost. This is because Android simulator does not understand localhost.

Now, when you create a build for the phone, it will connect to your server.

To enable sync for your model, go to model employee.rb and company.rb and add:

enable :sync
class Employee
  include Rhom::PropertyBag
   belongs_to :company_id, 'Company'
  # Uncomment the following line to enable sync with Employee.
  enable :sync
