A demonstration of the NestedList view in Sencha Touch.
Ruby JavaScript

This Git repository includes all of the source code used in creating a tutorial about the NestedList component in Sencha Touch.

The tutorial includes several checkpoints:

Using this repository to follow the screencast

First, you'll have to clone this repository:

git clone git://

Change into the directory:

cd Sencha-Touch-nested-list-demo

By default, the git clone command will only create the master branch locally. If you want to study the code at each checkpoint, you will have to fetch each of the other branches. You can do so by running the following:

git checkout -b 00_blank_slate origin/00_blank_slate
git checkout -b 01_setup_nested_list origin/01_setup_nested_list
git checkout -b 02_create_detail_card origin/02_create_detail_card
git checkout -b 03_add_metadata_to_listings origin/03_add_metadata_to_listings

You can review the list of local branches by running:

git branches

And you can switch between branches with the checkout command. For example, to check out the 03_add_metadata_to_listings branch, run:

git co 03_add_metadata_to_listings

Getting the sinatra app running

This example uses Sinatra to run a simple backend that serves json responses. To run it on your system, you will need to have Sinatra and postresql installed.

Installing Sinatra (and all dependencies)

Sinatra is a very simple web application framework written in ruby. If you have rubygems installed, then you can set up your environment simply by running the following from the root directory for this project:

gem install bundler
bundle install

This installs all of the dependencies required to make this Sinatra app run.

Create the database

Create the Postgres database:

createdb music_catalogue
rake db:seed

Deploying to Heroku


git push heroku master
heroku rake db:seed

Notes on getting the sinatra application running


  • rubygems 1.3.6 or newer
  • bundler
  • postgres

Troubles with postgres:

 ~/code/nested-list-demo: ) createdb music_catalogue
createdb: could not connect to database postgres: FATAL:  role "demo" does not exist
 ~/code/nested-list-demo: ) postgres
You must specify the --config-file or -D invocation option or set the PGDATA environment variable.

Nevermind. Lets just switch to using sqlite instead! Change:

DataMapper.setup(:default, (ENV["DATABASE_URL"] || 'postgres://localhost/music_catalogue'))

to DataMapper.setup(:default, (ENV["DATABASE_URL"] || "sqlite3:///#{File.expand_path(File.dirname(FILE))}/#{Sinatra::Base.environment}.db"))

Something went wrong with that request. Please try again.
