    • with device optimization and offline capability of “native mobile apps”
    • open source for rapid adoption by developers
  • 3. Platform Overview
    • Rhodes
      • “ microframework” for building locally executing natively optimized mobile apps
      • Developers run app generator for their objects of interest and then edit HTML templates
      • Contains first mobile Ruby implementation
    • RhoSync
      • Sync focused on web service data (needed in the age of SaaS)
  • 4. The Rhodes Microframework
    • a minimalist Ruby implementation for mobile devices
    • a Model-View-Controller "microframework" that consists of a directory structure and file naming convention. Writing to this framework primarily consists of editing a set of ERB templates for creating HTML to display data
    • the RhoSync synchronization engine client
    • a simple object relational manager (ORM) called Rhom
    • a web server which is installed on the mobile device and runs locally
    • The RhoGen app generator
  • 5. Sample Rhodes Apps
    • Rhomobile provides small set of enterprise apps
      • CRM - subset of SugarCRM’s capabilities: syncing to opportunities, contacts to device
      • Field service – Siebel field service
    • third party apps
      • TrailGuide (Basecamp) will release in a couple months
      • small number of vendors will accept GPL license
      • their source will be published on rhohub.com
      • highlight best of breed examples in several verticals: field service/MRO, medical, scientific
  • 6. Building a Rhodes App
    • Get your data (RhoSync)
      • Generate a sync source
      • Define your sync source adapter code
      • Test it from the web page
    • Generator your app (RhoGen)
      • Generate an app (in the Rhodes apps subdirectory for now)
      • Generate a model and scaffold code
    • Develop your app (Ruby/HTML editor of choice)
      • Edit your model controllers
      • Edit your HTML templates (ERB file)
    • Build, test, deploy (development environment for device)
      • Build your app
      • Test your app
      • Make available for download (or post to App Store)
  • 7. RhoSync Architecture RhoSync Server Rhodes runtime your app other app backends SugarCRM Siebel SalesForce BaseCamp SOAP SOAP SOAP REST REST
  • 8. Defining a Rhosync Source
    • Provide a Source Adapter class with
    • login- authentication code for the backend
    • query - retrieve or read's objects from the backend source
    • sync - take apart these objects and put them into a "property bag”
    • create
    • update
    • delete
    • logoff – not always necessary
  • 9. Generated Source Adapter Class
    • class <%=name%> < SourceAdapter
      • def initialize(source)
      • super
      • end
      • def login
      • #TODO: Write some code here
      • end
      • def query
      • # TODO: write some code here
      • end
      • def sync
      • # usually the generic base class sync does the job
      • super
      • end
      • def create(name_value_list)
      • #TODO: write some code here
      • end
      • def update(name_value_list)
      • #TODO: write some code here
      • end
      • def delete(name_value_list)
      • #TODO: write some code here if applicable
      • end
      • def logoff
      • #TODO: write some code here if applicable
      • end
    • end
