The Rhomobile Mission

Mobilize enterprise apps… cost-effectively witha great user experience. -provide the high level productivity and portability of

web programming- with device optimization and offline capability of “native mobile apps”- open source for rapid adoption by developers

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)

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

Sample Rhodes Apps Rhomobile provides small set of enterprise apps

CRM - subset of SugarCRM’s capabilities: syncing to opportunities, contacts to deviceField 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

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)

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

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

Sample Rhosync Source Query

select_fields = ['name','case_number','priority','status','type','description','resolution']

result = client.get_entry_list(session_id,'Cases','','case_number',0,select_fields,'10000',0);
