jMaki on Rails - Updated for NetBeans 6 M10
Based upon a user request, this is a follow up entry to show how jMaki on Rails For Dummies work on NetBeans 6 Milestone 10. Some of the steps are simplified and more details are provided. The updates from the previous blog entry are highlighted in this color.
- Download NetBeans 6.0 M10 (Full version) and configured to install only "Base IDE", "Java IDE", "Web and Java EE" and "Ruby" modules. A cutting-edge build can be obtained from the hudson build.
- Download and install
jMaki
plug-in in NetBeans update center.
- In NetBeans '
Tools', 'Plugins', select 'Downloaded', click on 'Add Plugins ...'. - Select the downloaded .NBM module, click on 'Install' button (bottom left corner). Follow the next few instructions to install jMaki plug-in and restart the IDE.
- To verify, go to '
Tools', 'Plugins', select 'Installed'. It should show 'jMaki Ajax support' with today's installation date.
- In NetBeans '
- Create a new "Ruby on Rails Application" Project, lets say named '
jmaki_ror'. Take everything else as default. - Create a new controller by right-clicking the project,
select '
Generate ...', select 'controller', specify the Name as 'jmaki' and Views as 'yahoo'. - jMaki-enable the Rails app
- Right click on your Rails project, select "Rails Plugins ...".
- Select the "Repositories" tab.
- Click "Add URL" and specify "
http://jmaki-goodies.googlecode.com/svn/trunk/rails_plugins". This adds the plug-in registry to the list of repositories used for searching plug-ins. - Now install the jmaki runtime. Select the "New Plugins" tab .
- Multi-select
jmaki_coreandjmaki_yahooand press "Install". Follow the instructions and the two plug-ins will be installed. After the installation is complete, you'll see the following:
and click on 'Close'. - Expand '
Views', right-click on 'layouts', select 'New', select 'RHTML file ...'. Enter the 'File Name' as 'standard'. This will add 'standard.rhtml' in layouts sub-tree. Enter the following fragment before <body>:
<head>
<%= stylesheet_link_tag "jmaki-standard", :media => "all" -%>
<%= javascript_include_tag "jmaki" -%>
<%= jmaki_setup -%>
</head> - Within <body>, add the following fragment:
<%= @content_for_layout %> - In '
Controllers', 'jmaki_controller.rb', add the following fragment before 'def yahoo' line:
layout "standard"
- Download and Configure the MySQL database
- Download MySQL 5.0 Community Server and install by taking all the default values.
- In a command prompt window, Start MySQL
server using the command: '
mysqld-nt --user root'. - Create database using the command: '
mysqladmin -u root create jmaki_ror_development'. You need to make sure that the database name in this script is changed to match the project name. - Right select the NetBeans project, select '
Generate', select 'model', specify the arguments as 'grid', click 'OK'. This will generate, in NetBeans project, Database Migrations, migrate,001_create_grids.rb. - Open
001_create_grids.rb, changeself.uphelper method such that it looks like:
def self.up
create_table :grids do |t|
t.column :company, :string
t.column :price, :float
t.column :change, :float
t.column :percent_change, :float
t.column :last_updated, :string
end
end - Right-select NetBeans project, select '
Run Rake Target', 'db', 'migrate'. This generates the database table. - Execute the query to insert data into the table.
- The easiest way to run this query is to run
mysql client in the command prompt window as: '
mysql --user root'. - Enter the command as '
use jmaki_ror_development' to see the following interaction:
mysql> use jmaki_ror_development;
Database changed - And then execute the query given below:
insert into grids values (1, 'A Co', 71.72, 0.02, 0.03, 'Jan 1, 2007, 10:00am' );
insert into grids values (2, 'B Inc', 29.01, 0.42, 1.47, 'Feb 1, 2007, 10:00am' );
insert into grids values (3, 'C Group Inc', 83.81, 0.28, 0.34, 'Mar 1, 2007, 10:00am' );
insert into grids values (4, 'D Company', 52.55, 0.01, 0.02, 'Apr 1, 2007, 10:00am' );
- The easiest way to run this query is to run
mysql client in the command prompt window as: '
- Add jMaki-wrapped Yahoo DataTable widget
- In NetBeans project, in '
Views', 'jmaki', 'yahoo.rhtml', drag-and-drop 'Data Table' widget from the 'Yahoo' category of jMaki palette.- Until the jMaki data model for grid and data
widgets is consistent between Java and JRuby, you need to replace the
generated code in '
yahoo.rhtml' with the following:
<%= jmaki_widget 'yahoo.dataTable',
:args => {
:columns => [
{ :title => 'Company', :width => 200, :locked => false },
{ :title => 'Price', :width => 75, :renderer => 'usMoney' },
{ :title => 'Change', :width => 75, :renderer => 'change' },
{ :title => '% Change', :width => 75, :renderer => 'pctChange' },
{ :title => 'Last Updated', :width => 85, :renderer => 'italic' }
]
},
:value => @table_data
-%> - '
@table_data' is defined in 'jmaki_controller' in 'def yahoo' as:
def yahoo
@table_data = []
Grid.find_all().each do |data|
@table_data << [ data.company, data.price, data.change, data.percent_change, data.last_updated]
end
end
- Until the jMaki data model for grid and data
widgets is consistent between Java and JRuby, you need to replace the
generated code in '
- In NetBeans project, in '
- That's it, run your app and view the page at '
http://localhost:3000/jmaki/yahoo'. Now jMaki-wrapped Yahoo DataTable widget is picking data from the MySQL database.
And as a next step, you can WAR'up this RoR application and deploy it on GlassFish V2 using these instructions.

How do we add pagination to this widget? Looking at the properties available for this widget in the documentation doesn't mention anything about pagination.

Chris, more details about jMaki pagination are available at:

Thank you for your response. Yes, I did read that article, but I was hoping their would be support for pagination as the original Yahoo DataTable has. Will the version in jMaki be updated to match what is available as part of the YUI tools?
