Example:

Criteria criteria = getSession().createCriteria(Order.class);
criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);

I will write here in a few weeks about my experiences with it. But the idea behind the framework is cool. Instead of writing native code you write web pages. That are interpreted by the browser widget of the device. But the web server is not running on a server somewhere in the internet, no it is running on the device so you can use the whole functionality of the devices API. Sounds cool, doesn’t it. Does anyone already has played with this framework, i am realy looking forward for some feedback.

Functions like:

NOW()

addDays(NOW(),1)

So I downloaded the source code of DbUnit and added them. You can downdload the patch here, or the patched jar here.

Short Documentation

In every DateTime field in your dbunit fixture you can use the following functions:

addDays(baseDate, days), addHours(baseDate, hours),

addMinutes(baseDate, minutes) and addSeconds(baseDate, seconds)

Example 1:

<table date="addDays(NOW(),2)"/>

Example: 2:

<table date="addDays(NOW(), -2)"/>

Example: 3:

<table date="addSeconds(2000-01-01 00:00:00, 1)"/>

It was very helpful for me, I hope it is also helpful for you. If you find any bugs or have ideas for improving the functionality, do not hesitate to write a comment.

What I found was the FULLTEXT index of mysql.

In Detail it is described here. I provide you a short summary:

1. Create a fulltext index

ALTER TABLE entities ADD FULLTEXT KEY search_text (title);

2. Execute a select

SELECT id,title FROM entities WHERE  MATCH(title) AGAINST (’jazz’ IN BOOLEAN MODE);

My approach is very easy. Just use standard sqlite and like.

A statement will look then like: SELECT * FROM table WHERE hackstack like ‘%needle%’;

Because like is case insensitive it fits my needs quite good. Of course no stemming, but that is okay for me.

Installing Ruby

First you need to install ruby.

1. Download the latest ruby version from http://www.ruby-lang.org/en/downloads/ .
2. Execute the installer.
3. Add the Path to the ruby executable to your PATH. (You find detailed description how to expand the PATH here.)

Install Gem

Gem is the ruby packet manager. We need it beecause rails is a gem itself.

1. Download the latest version ruby gems from http://rubyforge.org/frs/?group_id=126
2. Exctract the archive
3. Navigate on a command shell to the top directory (This directory contains the file setup.rb)
4. Execute the setup file with the command : ruby setup.rb

Installing rails

We already installed ruby and the gem packet manager. The last step is that we install rails itself.

1. Open a command shell.
2. Type the command : gem install rails.

That’s it ! If you want to test your installation just type on your command shell the following command.

rails myapp

This should create a rails app skeleton with the name myapp.

undefined method `controller_path' for SupportMailer:Class

That is because the actionmailer does not support partials out of the box. (here is the belonging Trac Ticket) .

But there are two workarounds:

Patching the actionmailer staticly

This workaround is metioned in the Bug Report so I will describe its usage first, though I don’t like it.

1. open your ruby directory (C:\Programm files\ruby or /usr/local/ruby) and then navigate to this subdirectory lib\ruby\gems\1.8\gems\actionmailer-1.x.x\lib\action_mailer.
2. open the file base.rb
3. add the following line right before/above the private statement:

   # enable partials in ActionMailer templates, there is still a lot to be
   # done to make it work with auto multi-part partials
   def self.controller_path #:nodoc:
     return  ''
   end

4. Restart your Server

That’s it. Now you can use partials inside your mail templates.

Patching the actionmailer at runtime

This is my prefered way to deal with this “Bug”.

I add  the following file in my rails app under the path config/actionmailer_patch.rb

module ActionMailer

  class Base

    # enable partials in ActionMailer templates, there is still a lot to be
    # done to make it work with auto multi-part partials
    def self.controller_path #:nodoc:
      return  ''
    end
  end
end

Then include this file to your rails app by adding the following line to your config/environment.rb file:

require "actionmailer_patch"

After a restart of your webbrick server/fcgi process you should be able to use partials in ActionMailer Templates.

Comparing the solutions

The first solution has to be executed on every computer you run your app on. After every upgrade of the actionmailer this task has to be redone.

The second solution has to be done for every of your rails apps.

I usally have more mashiens and version sthen apps, that is why I prefer the second solution.
