As expected GlassFish is the most prominent topic. And then there are several entries on NetBeans, JRuby/Rails, several Java EE 6 technologies like JPA, JAX-WS, JAX-RS, EJB, and JSF, and more entries on Eclipse, OSGi and some other tecnhologies too.

TOTD #80: Sinatra CRUD application using Haml templates with JRuby and GlassFish Gem

Filed under: glassfish, netbeans, sinatra, totd — Tags: jruby, mysql, sintara — arungupta @ 2:00 am

TOTD #79 showed how to run a trivial Sinatra application using GlassFish Gem. Sinatra provides support for Haml, Erb, Builder, Sass, and Inline templates as described here. This TOTD will show how to get started with creating a Sinatra CRUD application using Haml templates.

Haml is based on one primary principle – Markup should be beautiful because beauty makes you faster.

Get started by installing the Haml gem as:

/tools/jruby-1.2.0 >./bin/jruby -S gem install haml –no-ri –no-rdoc
JRuby limited openssl loaded. gem install jruby-openssl for full support.
http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL
Successfully installed haml-2.0.9
1 gem installed

And follow the tutorial, documentation, and reference page for more details.

Sinatra is ORM-agnostic and so any Ruby ORM framework such as ActiveRecord, DataMapper, Sequel, and others. DataMapper with JRuby requires work so this TOTD will show how to use ActiveRecord instead. There is sinatras-hat which allows to create RESTy CRUD apps with Sinatra. There probably are mutiple other ways to create this application but I prefer to understanding the wiring so this blog will use a bare minimal structure.

Anyway, lets get started!

Create the database as:

~/tools/jruby/samples/sinatra-sample >mysql –user root
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 664
Server version: 5.1.30 MySQL Community Server (GPL)

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

mysql> create database hello_development;
Query OK, 1 row affected (0.00 sec)

mysql> use hello_development;
Database changed
mysql> CREATE TABLE `runners` (`id` int(11) DEFAULT NULL auto_increment PRIMARY KEY, `distance` float, `minutes` int(11), `created_at` datetime, `updated_at` datetime);
Query OK, 0 rows affected (0.06 sec)

Update “hello.rb” from TOTD #79 such that it looks like:

require ‘rubygems’
require ’sinatra’
require ‘activerecord’

## Setup

ActiveRecord::Base.establish_connection(
:adapter => “jdbcmysql”,
:host => “localhost”,
:username => “root”,
:password => “”,
:database => “hello_development”
)

## Models

class Runner < ActiveRecord::Base
end

## Controller Actions

get ‘/hi’ do
“Hello World!”
end

get ‘/’ do
@runner = Runner.find(:all)
haml :index
end

get ‘/new’ do
haml :new
end

get ‘/:id’ do
@runner = Runner.find(params[:id])
if (@runner)
haml :show
else
redirect ‘/’
end
end

post ‘/’ do
@runner = Runner.new(:distance => params[:distance], :minutes => params[:minutes])
if @runner.save
redirect “/#{@runner.id}”
else
redirect ‘/’
end
end

Firstly, it pulls in the ActiveRecord dependency. Then “ActiveRecord::Base.establish_connection” is used to establish a connection with the previously created database. “Runner” is tagged as a model class by inheriting from “ActiveRecord::Base” and uses the default table name (“runners” in this case). Add four new methods:

Three GET methods to show all the runners, a form to enter new data, and show a particular log entry. Each method requires a HAML template (will be created in next step) to render the information.
One POST method to save the newly created log entry in the database.

Create a new directory “views” and create the following files in that directory. Each file serves as a view and rendered from an action in “hello.rb”.

“index.haml”: Show all the runners

%h1 Listing all runners …
%table
%tr
    %th Distance
    %th Minutes
– @runner.each do |r|
    %tr
      %td= r.distance
      %td= r.minutes
%br
%a{:href=>”/new”}
New Runner

“new.haml”: Enter a new entry

%h1 Adding a new runner log …
%form{:method=>”post”, :action=>”/”}
Distance:
%input{:type=>”text”, :name=>”distance”}
%br
Minutes:
%input{:type=>”text”, :name=>”minutes”}
%br
%input{:type=>”submit”, :value=>”Submit”}
%br

“show.haml”: Show a particular log entry

%h1 Showing a runner log …

Distance:
= @runner.distance
%br
Minutes:
= @runner.minutes
%br
%br
%a{:href=>”/”}= “Show All!”

The complete directory structure looks like:

.
./hello.rb
./views
./views/index.haml
./views/new.haml
./views/show.haml

That’s it, now run the application as:

~/tools/jruby/samples/sinatra-sample >../../bin/jruby -S glassfish
Starting GlassFish server at: 192.168.1.145:3000 in development environment…
Writing log messages to: /Users/arungupta/tools/jruby-1.2.0/samples/sinatra-sample/log/development.log.
Press Ctrl+C to stop.

The main page is available at “http://localhost:3000/” and looks like:

Clicking on “New Runner” gives …

Enter the data, and click on “Submit” to show …

Click on “Show All!” to see all the entries added so far …

And after adding few entries the main page looks like …

This application shows Create and Read from the CRUD, it’s fairly easy to add Update and Delete functionality as well but that’s an excercise left for the readers

You’ll hear all about it at Develop with Pleasure, Deploy with Fun: GlassFish and NetBeans for a Better Rails Experience at Rails Conf next week.

TOTD #79: Getting Started with Sinatra applications on JRuby and GlassFish Gem

Filed under: glassfish, netbeans, sinatra, totd — arungupta @ 6:00 am

Sinatra is a DSL for quickly creating web-applications in Ruby with minimal effort. Like Rails and Merb, Sinatra is not an MVC framework and basically follows a flat-file structure instead. The framework define conventions such as location of static files and views, bootstrap, dev/production/test environment variables, filters, helpers, TDD, and much more. Read Getting Started for complete details. Even though Sinatra is not a MVC framework but sinatra-gen may be used to generate new Sinatra projects.

GlassFish Gem can easily run Rails, Merb, Sinatra, and any other Ruby framework applications based upon Rack. TOTD #70 shows how to run Rails applications and TOTD #53 shows to run Merb applications. This TOTD will explain how to run a trivial Sinatra application. A later blog will describe how to plug a generic Rack-based framework.

Lets see how to get started with Sinatra using JRuby and GlassFish gem.

Install Sinatra gem as:

~/tools/jruby >./bin/jruby -S gem install sinatra
JRuby limited openssl loaded. gem install jruby-openssl for full support.
http://wiki.jruby.org/wiki/JRuby_Builtin_OpenSSL
Successfully installed sinatra-0.9.1.1
1 gem installed
Installing ri documentation for sinatra-0.9.1.1…
Installing RDoc documentation for sinatra-0.9.1.1…

Create a directory “sinatra-sample”, create a file “hello.rb” in that directory with the contents shown below:

require ‘rubygems’
require ’sinatra’
get ‘/hi’ do
“Hello World!”
end

Run your sample using GlassFish gem as:

~/tools/jruby/samples/sinatra-sample >../../bin/jruby -S glassfish
Log file /Users/arungupta/tools/jruby-1.2.0/samples/sinatra-sample/log/development.log does not exist. Creating a new one…
Starting GlassFish server at: 192.168.1.145:3000 in development environment…
Writing log messages to: /Users/arungupta/tools/jruby-1.2.0/samples/sinatra-sample/log/development.log.
Press Ctrl+C to stop.

And then the output is available at “http://localhost:3000/hi” and looks like:

Neat and simple!

You’ll hear all about it at Develop with Pleasure, Deploy with Fun: GlassFish and NetBeans for a Better Rails Experience at Rails Conf next week.

Here is the order in which I’ll seek any help:

Project Website
IRC #sinatra
Twitter
Mailing List

The next blog will show how to create a Sinatra CRUD application and run it using GlassFish.

Please leave suggestions on other TOTD (Tip Of The Day) that you’d like to see. A complete archive of all the tips is available here.
