Any way i got article from sobbour website, but  i am not satisfied with the code because the component automatically resize for big and thumb by 2 method directly, it will make bounced my hosting with trash image. And some lines were not realible any more with CakePHP, here is my modified Code (save it to /appName/controller/components/image.php)

<?php

class ImageComponent extends Object

{

var $contentType = array(‘image/jpg’,'image/bmp’,'image/jpeg’,'image/gif’,'image/png’,'image/pjpg’,'image/pbmp’,'image/pjpeg’,'image/ppng’,'image/pgif’);

function upload_image_and_thumbnail($fileData,$size,$subFolder,$prefix) {

if (strlen($fileData['name'])>4)

{

$error = 0;

$destFolder = WWW_ROOT.$subFolder;

$realFileName = $fileData['name'];

if(!is_dir($destFolder)) mkdir($destFolder,true);

$filetype = $this->getFileExtension($fileData['name']);

$filetype = strtolower($filetype);

if(!in_array($fileData['type'],$this->contentType)){

return false;exit();

}

else if($fileData['size'] > 700000 ){

return false;exit();

}

else

{

$imgsize = GetImageSize($fileData['tmp_name']);

}

if (is_uploaded_file($fileData['tmp_name']))

{

if (!copy($fileData['tmp_name'],$destFolder.’/’.$realFileName ))

{

return false;

exit();

}

else {

$this->resize_img($destFolder.’/’.$realFileName, $size, $destFolder.’/’.$prefix.$realFileName);

unlink($destFolder.’/’.$realFileName);

}

}

return $fileData;

}

}

function delete_image($filename)

{

unlink($filename);

}

function resize_img($tempFile, $size, $newFile)

$filetype = $this->getFileExtension($tempFile);

$filetype = strtolower($filetype);

switch($filetype) {

case “jpeg”:

case “jpg”:

break;

case “gif”:

break;

case “png”:

$img_src = imagecreatefrompng ($tempFile);

case “bmp”:

$img_src = imagecreatefromwbmp ($tempFile);

break;

}

$true_width = imagesx($img_src);

$true_height = imagesy($img_src);

$size = explode(‘x’,strtolower($size));

if ($true_width>=$true_height)

{

$width=$size[0];

$height = ($width/$true_width)*$true_height;

}

else

{

$height=$size[1];

$width = ($height/$true_height)*$true_width;

}

$img_des = imagecreatetruecolor($width,$height);

imagecopyresampled ($img_des, $img_src, 0, 0, 0, 0, $width, $height, $true_width, $true_height);

// Save the resized image

switch($filetype)

{

case “jpeg”:

case “jpg”:

imagejpeg($img_des,$newFile,80);

break;

case “gif”:

imagegif($img_des,$newFile,80);

break;

case “png”:

imagepng($img_des,$newFile,80);

break;

}

}

function getFileExtension($str)

{

$i = strrpos($str,”.”);

if (!$i) { return “”; }

$l = strlen($str) – $i;

$ext = substr($str,$i+1,$l);

return $ext;

}

}

?>

<?php

class DeJavu extends Appcontroller {

var $components = array(“Image”);

function add(){

….any code….

$this->Image->upload_image_and_thumbnail($this->data['Webinfo']['file'],’150×150′,’img’,'logo_’);

….any code….

}

}

?>

<?xml version=”1.0″ encoding=”utf-8″?>
<mx:Application xmlns:mx=”http://www.adobe.com/2006/mxml” layout=”absolute” creationComplete=”creationComplete()”>
<mx:Script source=”streaming.as”/>
<mx:TextInput x=”10″ y=”10″ id=”rtmpUrl” text=”your rtmp address”/>
<mx:Button x=”216″ y=”10″ id=”connectBtn”/>

<mx:TextArea x=”10″ y=”40″ height=”221″ id=”msgBoard” width=”222″ />
<mx:Button x=”178″ y=”269″ id=”sendBtn”/>
</mx:Application>

And now let create streaming.as script :

import flash.events.MouseEvent;
import flash.events.NetStatusEvent;
import flash.events.SyncEvent;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.net.SharedObject;

import mx.controls.Alert;

public var NetCont:NetConnection;
public var NetStrem:NetStream
public var SharObj:SharedObject;

public function creationComplete():void{
connectBtn.label = “Connect”;
connectBtn.addEventListener(MouseEvent.CLICK, ConnectServer);

sendBtn.label = “Send”;
sendBtn.addEventListener(MouseEvent.CLICK, SendChat);
}

public function ConnectServer(event:MouseEvent):void{
NetCont = new NetConnection();
NetCont.client = new NetConnectionClient;
NetCont.connect(rtmpUrl.text);
NetCont.addEventListener(NetStatusEvent.NET_STATUS, createSharedObject);
}

public function createSharedObject(event:NetStatusEvent):void{

if(NetCont.connected){
SharObj = SharedObject.getRemote(“SampleMessage”,NetCont.uri,false,false);
SharObj.connect(NetCont);
SharObj.addEventListener(SyncEvent.SYNC, SharObjView);

}else{

Alert.show(‘Unable to Connect Internet or Rtmp Address’);

}
}

public function SharObjView(event:SyncEvent):void{
msgBoard.htmlText += SharObj.data['SampleMessage']+”<br>”;

}

public function SendChat(event:MouseEvent):void{
SharObj.setProperty(“SampleMessage”,enterMsg.text);
}

There are 2 optional for using SharedObject in ActionScript specially for flex SharedObject.getLocal() method or the SharedObject.getRemote()

What we use for internet connection is using getRemote. And here is code for next connection client :

package
{
public class NetConnectionClient
{
public function NetConnectionClient()
{
}
public function onBWDone(… rest):void
{

}
public function onBWCheck(… rest):uint
{
//have to return something, so returning anything
return 0;
}

public function onMetaData(info:Object):void {
trace(“metadata: duration=” + info.duration + ” width=” + info.width + ” height=” + info.height + ” framerate=” + info.framerate);
}
}
}

SELECT *, COUNT(addresses.id) AS jumlah_address
FROM users LEFT OUTER JOIN addresses ON addresses.user_id = users.id
GROUP BY users.id

Is that you will do ? it will give you result = 1, it should be 0. So, let look to query below :

SELECT *, IF(addresses.id IS NULL, 0, COUNT(addresses.id)) AS jumlah_address
FROM users LEFT OUTER JOIN addresses ON addresses.user_id = users.id
GROUP BY users.id

For More complex sorting and case :

example if user want sort based on city name then user name, but if Jakarta and Bandung are sorted at the top before other cities alphabetically. Here’s the way:

SELECT *, IF(city == ‘Jakarta’, 0, IF(city == ‘Bandung’, 1, 2)) AS city_index
FROM users LEFT OUTER JOIN addresses ON addresses.user_id = users.id
GROUP BY users.id
ORDER BY city_index ASC, city ASC

I just want share my testing with Ruby coverage code or Rcov. It is fun (for me, dont know for others) playing with Rcov report, i think it is like bugs tracking but i dont know other people called it or maybe it is like tool to coverage test your application codes.

First think you have to do is installing the gem :

gem install rcov

and then write simple code to run it as rake then save it in your_app/lib/tasks :

require ‘rcov/rcovtask’

namespace :test do
namespace :coverage do

desc “Delete aggregate coverage data.”

task(:clean) { rm_f “coverage.data” }
end

desc ‘Aggregate code coverage for unit, functional and integration tests’

task :coverage => “test:coverage:clean”

%w[unit functional integration].each do |target|

namespace :coverage do

Rcov::RcovTask.new(target) do |t|

t.libs << "test"
t.test_files = FileList["test/#{target}/*_test.rb"]
t.output_dir = File.dirname(__FILE__)+”/report_rcov/#{target}”
t.verbose = true
t.rcov_opts << '–rails –aggregate coverage.data'

end
end

task :coverage => “test:coverage:#{target}”

end

system(” \”C:/Program Files/Mozilla Firefox/firefox.exe\” ” +
“file:///”+File.dirname(__FILE__)+”/report_rcov/unit/index.html”)

end

Absolutly i am using windows if you are using another OS not windows you could change the 4th line from bottom to :

system(open File.dirname(__FILE__)+”/report_rcov/unit/index.html”)

Open your shell or CMD then execute rake test:coverage or open rake -T

rake test:coverage # Aggregate code coverage for unit,…
rake test:coverage:clean # Delete aggregate coverage data.
rake test:coverage:clobber_functional # Remove rcov products for functional
rake test:coverage:clobber_integration # Remove rcov products for integration
rake test:coverage:clobber_unit # Remove rcov products for unit
rake test:coverage:functional # Analyze code coverage with tests …
rake test:coverage:integration # Analyze code coverage with tests …
rake test:coverage:unit # Analyze code coverage with tests …

Here I attached sample report from rcov. I hope this written can be useful for you gentleman and ladies.

ActiveRecord::Base.connection.execute ‘select * from users’

To return array of hashes, you can use it :

ActiveRecord::Base.connection.select_all

.

I am writing this article with accompanied by a cup of coffee while waiting MU Vs Chealsea for Champion Final. Back to the topic. You should know many familiar online translation like google and altavista. Now i will like to introduce you about gibberish in rails. Let start it :

• Install the plugin to your app rails.

ruby script/plugin install http://svn.myutil.com/projects/plugins/gibberish_rails/
or
ruby script/plugin install svn://errtheblog.com/svn/plugins/gibberish

• After that go to your Application_controller.rb then use arround_filter for implementation of gibberish :

class ApplicationController < ActionController::Base
around_filter :set_language

private
def set_language
Gibberish.use_language(session[:language]) { yield }
end
end

• Another method is described in README file. Like :

class ApplicationController < ActionController::Base
around_filter :use_best_guess_locale

private
def use_best_guess_locale
session[:locale] = GibberishRails.best_guess_locale(params[:locale], request.env['HTTP_ACCEPT_LANGUAGE']) if ( ! session[:locale] || params[:locale] || RAILS_ENV == ‘development’ )

Gibberish.use_language(session[:locale]) {yield}
end
end

• To create new dictionary, you can create it in YAML file such as es.yaml :

welcome_friend: ¡Recepción, amigo!
welcome_user: ¡Recepción, {user}!
love_rails: Amo los carriles.

• Need more information & interaction ? Browse here

_

• Install the plugin to your ruby app

ruby script/plugin install http://os.flvorful.com/svn/plugins/super_in_place_controls

• In your layout or rhtml / html.erb put it :

<%= stylesheet_link_tag ‘in_place_styles’ %>

• Done !!, let start to implement it in your view file (click the image below to enlarge).

• For regular text_field you can change it to be :

in_place_text_field :product, :title

• For regular text_area, you can change it to be :

in_place_text_area :product, :description

• For regular select_tag, you can change it to be:

in_place_select :product, :product_type, :choices => %w(Awesomeness Coolness Phatness RubyBliss).map { |e| [e, e] }

• For regular radio_collection, you can change it to be :

in_place_radio :product, :price, :choices => %w(199 299 399 499 599 699 799 899 999).map { |e| [e, e] }

• For check box collection you can change it to be:

in_place_check_box :product, :category_ids, :choices => Category.find(:all).map { |e| [e.id, e.title] }, :display_text => :collection

• And for date you can change to be :

in_place_date_select :product, :display_begin

• for more style you can addcalendar_date_select_includes "blue" to the pages you want to use the calendar select on. The other styles for the calendar_date_select are “blue”, “plain”, “red”, “silver”, “default”.

• Online Demo : DEMO

• Get API Key HERE

• Download this code and paste it to your app_name/lib folder

• Then in your controller, put it :

require ‘daylife’
a = Daylife::API.new(‘your api key’,'sharedsecret’)
r = a.execute(‘search’,'getRelatedArticles’, :query => ‘sam adams’, :limit => 5)
if(r.success?)
r.articles.each {|a| puts a.headline }
puts r.articles[1].source.daylife_url
else
# output the error message
puts “Error: #{r.code}: #{r.message}”
end

• Now your dream comes true to have site like Yahoo News or at least like daylife.com

• What else can you do with this dayAPI? Read More Here

• Has been tested and working nice
