HTTP AUTH logout method

Jozsef — Tue, 12 Mar 2013 12:27:23 +0000

This code cause logout feeling for your user. The browser will ask again the username and password.

<?php
  header('WWW-Authenticate: Basic realm="protected area"');
  header('HTTP/1.0 401 Unauthorized');
?>

I use it with a logout controller, that set a session variable to true and redirect the request to the home page. And the home page check this session variable, and if it true, it sends these headers and set back the session variable to null.

This is my method, but you can use this HTTP auth logout method as you like.

Fastest and easy to use URL shortener

Jozsef — Tue, 31 Jul 2012 13:57:46 +0000

Here is my favorite URL shortener tool: RX.hu. This is fast and really easy to use URL shortener. There are some alias for it: resize-linx.com, resize-links.com, resizelinks.com, etc. All of these are the same link shortener tool. No advertisement all. There is the fastest redirection that I have ever seen. Try it and use it.

jQuery link click href value

Jozsef — Wed, 02 Nov 2011 18:24:28 +0000

I've wrote these words on google. And I don't find the exact solution.

The problem:
What Should I write in the href? If I write # sign then browser go to the top of page. I wouldn't like to go to the top of page.

Here is the HTML:

<a href="#" id="example" >Click</a>

jQuery code:

<script>
$('#example').click(function() {
  alert('Hello');
  return false;
});
</script>

The
return false;
command is the key. When use this return value. The links lost their default behavior.

PHP normalize function

Jozsef — Fri, 07 Oct 2011 09:54:58 +0000

I post my normalization function. This function find all illegal characters (like: Ő, Ű, ú, í, etc. ) and replace it to latin1 chars. (like: O, U, u, i, etc.) This function works for me on hungarian words. Try it on your text and post your comment about it.

<?php
function normalize($string) {
    $string = strtr($string, array('ő' => 'o', 'ű' => 'u', 'Ő' => 'O', 'Ű' => 'U'));
    $a = 'ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖŐØÙÚÛÜŰÝÞßàáâãäåæçèéêëìíîïðñòóôõöőøùúûűüýýþÿŔŕ';
    $b = 'AAAAAAACEEEEIIIIDNOOOOOOOUUUUUYbsaaaaaaaceeeeiiiidnooooooouuuuuyybyRr';
    $string = utf8_decode($string);    
    $string = strtr($string, utf8_decode($a), $b);
    return utf8_encode($string);

Locomotive CMS

Jozsef — Mon, 18 Jul 2011 18:15:30 +0000

Today, I found a really good CMS. I'm looking for ruby 3 CMS for a while. I found this CMS solution that use my favorite NoSQL database system: MongoDB. I think multi site feature is rare in ror applications. Locomotive CMS do it.

Locomotive is an open source CMS for Rails 3. It's super flexible and integrates with Heroku and Amazon

Some features from technical Specs:
My favorite point: MongoDB with Mongoid
I've already used in some project: Devise authentication solution. I think this is the best authentication gem.
HAML: HTML Abstraction Markup Language. I think SASS and HAML make easy html writing.
The following items were totally new for me:

Liquid
Safe, customer facing template language
Formtastic
Form builder with semantically rich / accessible markup
InheritedResources
Makes controllers more powerful and cleaner
Carrierwave
Classier solution for file uploads
Jammit-S3
Industrial Strength Asset Packaging

I try this awesome CMS and I will post about my experiences.

Resolve Ruby on Rails UTF-8 error message: invalid multibyte char (US-ASCII)

Jozsef — Fri, 11 Feb 2011 11:02:21 +0000

I got the following error when i run a rake db:seed command on may RoR application:
invalid multibyte char (US-ASCII)

I found the soution and the error has gone away:
You should add a line to your file:

# encoding: utf-8

You can change the utf-8 to any other encoding that you use.
I added this line to my seeds.rb file and all UTF-8 code have been executed without errors.

Update:
The good news: ruby 2.0+ has utf-8 default encoding. If you use 2.0 or newer you don't need to insert this line to your code.

Good luck!

how to install Ruby on rails webshop?

Jozsef — Fri, 04 Feb 2011 15:52:03 +0000

You have installed RoR3 and now you want to install a rails3 webshop.

I think the best solution is Spree. This is the only rails3 based e-commerce solution at this time.

How do you install this shop?

rails new rails3-shop
cd rails3-shop

edit Gemfile and add new line

gem 'spree'

Install new spree site.

rails g spree:site
rake spree:install
rake db:migrate
rake db:seed
rails server

The rails server command starts the webrick server. You should go to http://localhost:3000/ to check spree.
The first registration will be the admin user.

HTML number formatting with PHP

Jozsef — Tue, 04 Jan 2011 07:32:16 +0000

Here is my HTML number formatter. Sometimes the browsers wrap the numbers along thousand separator or decimal pont, but this function prevents this event.

function html_number_format($number, $decimals = 2, $dec_point = '.', $thousands_sep = ',') {
  if ($number === FALSE) {
    return '---';
  }
  return '<span style="white-space: nowrap;">'.number_format($number, $decimals, $dec_point, $thousands_sep).'</span>';

How to install Phusion Passenger for ruby 1.9.2

Jozsef — Sun, 03 Oct 2010 10:32:59 +0000

There are some easy steps to install Phusion Passenger for ruby 1.9.2 and apache2 on Ubuntu Linux.

1. Install rvm system wide
sudo bash < <( curl -L http://bit.ly/rvm-install-system-wide )

2. Install ruby 1.9.2
rvm install 1.9.2

3. add new line in /etc/bash.bashrc
[[ -s /usr/local/lib/rvm ]] && . /usr/local/lib/rvm

4. install passenger
sudo -i # you need root shell rvm use 1.9.2-p0@global # or your version, use: rvm list gem install passenger --pre # only passenger 3 works with 1.9.2 that is in beta state

5. install apache module
passenger-install-apache2-module

6. create /etc/apache2/mods-available/passenger.load file for loading
/usr/local/rvm/gems/ruby-1.9.2-p0@global/gems/passenger-3.0.0.pre4/ext/apache2/mod_passenger.so file:
LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.2-p0@global/gems/passenger-3.0.0.pre4/ext/apache2/mod_passenger.so

7. create /etc/apache2/mods-available/passenger.conf file:
PassengerRoot /usr/local/rvm/gems/ruby-1.9.2-p0@global/gems/passenger-3.0.0.pre4 PassengerRuby /usr/local/rvm/wrappers/ruby-1.9.2-p0@global/ruby

8. Optional virtual host in the common way
Suppose you have a Rails application in /somewhere. Add a virtual host to your
Apache configuration file and set its DocumentRoot to /somewhere/public:

ServerName www.yourhost.com
DocumentRoot /somewhere/public # <-- be sure to point to 'public'!

AllowOverride all # <-- relax Apache security settings
Options -MultiViews # <-- MultiViews must be turned off

9. Enable passenger module and config
a2enmod passenger

10. restart apache
/etc/init.d/apache2 restart

11. Deploy your ruby on rails or rack based application.

PHP: easy to use open-source Timer class

Jozsef — Thu, 29 Apr 2010 16:39:36 +0000

I share my Timer class with you. This is an easy to use class. If you use this you will never have to think about the way of execution time measuring.

PHP Timer class

<?php
/**
 * Usage:
 * $timer = new Timer();
 * // Run some important slow or fast commands...
 * echo $timer;
 * 
 * <small>Execution time: 3.456434 sec</small>
 */
class Timer {
    /**
     * Microtime when object has started in second.
     * @var float
     */
    protected $time;

    /**
     * Output string for display ellapsed time.
     * @var string sprintf formatted string.
     */
    protected $template;

    public function __construct($template = '<small>Execution time: %f sec</small>') {
        $this->template = $template;
        $this->reset();
    }

    /**
     * Get elapsed time.
     * @return float Ellapsed time since object creation in second.
     */
    public function getTime() {
        return microtime(TRUE) - $this->time;
    }

    /**
     * Set timer to zero. And start again.
     */
    public function reset() {
        $this->time = microtime(TRUE);
    }

    public function __toString() {
        $time = $this->getTime(); //
        return sprintf($template, $time);
    }

How can you generate thumbnail with php?

Jozsef — Mon, 26 Apr 2010 20:28:11 +0000

You can read about two popular thumbnail generating methods in this article. The first method requires GD library. If you select the other way you need Imagick which is a native php extension to create and modify images using the ImageMagick API. Let's see the code!

First method: GD library

function gd_thumbnail($filename, $width = 200, $height = 200) {
    $source = imageCreateFromString(file_get_contents($filename));
    $x = imageSX($source);
    $y = imageSY($source);

    if ($x > $y) { // landscape orientation
        $height = intval($y/($x/$width));
    } else { // square or portrait orientation
        $width = intval($x/($y/$height));
    }

    $destination = ImageCreateTrueColor($width, $height);
    imageCopyResamled($destination, $source, 0, 0, 0, 0, $width, $height, $x, $y);
    imagejpeg($destination, NULL, 92);
}

Second method: Imagick extension

function im_thumbnail($filename, $width = 200, $height = 200) {
    $image = new Imagick($filename);
    $image->thumbnailImage($width, $height, TRUE);
    echo $image;
}

Usage

You can generate thumbnail image to visitor's browser:

header('Content-type: image/jpeg');
im_thumbnail('path/to/image.jpg'); // you can use gd_thumbnail() here

This code will response a JPEG image.

You can save thumbnail image to file:

$fileContent = gd_thumbnail('path/to/image.jpg'); // you can use im_thumbnail() here
file_put_contents('path/to/image_thumbnail.jpg', $fileContent); // save image

This is very easy, isn't it?

Have a nice day, and use these code as you need.

    $x = imageSX($source);
    $y = imageSY($source);

    if ($x > $y) { // landscape orientation
        $height = intval($y/($x/$width));
    } else { // square or portrait orientation
        $width = intval($x/($y/$height));
    }

    $destination = ImageCreateTrueColor($width,$height);
	imageCopyResampled($destination,$source,0,0,0,0,$width,$height,$x,$y);
    imagejpeg($destination);
}

function im_thumbnail($filename, $width= 200, $height = 200) {
    $image = new Imagick($filename);
    $image->thumbnailImage($width, $height, TRUE);
    echo $image;
}

header('Content-type: image/jpeg');


//$t = new Timer();

im_thumbnail('IMG_4449.JPG');

PHP: How to get public properties of object

Jozsef — Fri, 16 Apr 2010 10:08:48 +0000

Sometimes you need all public properties of an object. I've also met this problem. I tried to find some usable native function on php.net, but the only native solution is the ReflectionProperty class. I think It claims too much resource. I've written an own function that has solved this issue.

Let's see the function

/**
 * It gets all public properties of given $object.
 * @param object $object It must be object.
 * @return array that contains all public property name as key and their values. example:
 * array('property1' => array('foo'), 'property2' => false);
 */
function getPublicProperties($object) {
    $result = get_object_vars($object);
    if ($result === NULL or $result === FALSE) {
        throw new ValueException('Given $object parameter is not an object.');
    }
    return $result;
}

Why does this function work so good?

This function works well when you call inside actual object either you call outside the object, because in both situation the function can see only public properties. The result is a hash. You can search faster on hash than in number indexed array: isset($hash['property']) or array_key_exists('property', $hash) is faster than in_array('property', $array) would be. So we are lucky because get_object_vars($object); returns with hash. The keys of this hash are the name of property.

How to generate dynamic javascript files with Ruby on Rails?

Jozsef — Thu, 07 Jan 2010 11:35:28 +0000

The problem

I want to write JavaScript files that use dynamic informations via Ruby on Rails. I think my solution also works with rails 2 and 3.
What can dynamic JavaScript do for you? You can write JavaScript on your ERB (embedded ruby) file beside HTML code. This is very simple, but not the best solution for a longer jQuery script.
For example:
Translation in JavaScript: translation with I18n.t() Rails method would be great in separated JavaScript file with ERB capability.

// some jquery code before alert
alert(<%= I18n.t(:forbidden_message) %>);
// some jquery code after alert

My solution

You will read about my ERB generated JavaScript solution. Haml users also can use this method.
Let see the tutorial.

ERB dynamic JavaScript with Ruby on Rails tutorial

Create a new project for this tutorial:

rails new dynamic_js_tutorial
cd dynamic_js_tutorial

Generate "js" controller, with following command on directory of your rails project:

rails generate controller js script1 script2 script3

This command produces the following output:

      create  app/controllers/js_controller.rb
       route  get "js/script3"
       route  get "js/script2"
       route  get "js/script1"
      invoke  erb
      create    app/views/js
      create    app/views/js/script1.html.erb
      create    app/views/js/script2.html.erb
      create    app/views/js/script3.html.erb
      invoke  test_unit
      create    test/functional/js_controller_test.rb
      invoke  helper
      create    app/helpers/js_helper.rb
      invoke    test_unit
      create      test/unit/helpers/js_helper_test.rb

Rename *.html.erb files to *.js on js views directory:

mv app/views/js/script1.html.erb app/views/js/script1.js
mv app/views/js/script2.html.erb app/views/js/script2.js
mv app/views/js/script3.html.erb app/views/js/script3.js

This extension helps the editors, IDEs and programmers to recognize JavaScript syntax type.

You should modify app/controllers/js_controller.rb file:

class JsController < ApplicationController
  layout false # This controller generates only javascript files
  before_filter :js_content_type # set HTTP header information 
   
  def js_content_type
     response.headers['Content-type'] = 'text/javascript; charset=utf-8'
  end

  def script1
    @dynamic_message = "hello" # modified
  end

  def script2

  end

  def script3

  end
end

Edit app/views/js/script1.js javascript file:
```
alert('<%= @dynamic_message %>');
```

Include script1.js in your layout file (app/views/layouts/application.html.erb):

<!DOCTYPE html>
<html>
<head>
  <title>JsProba</title>
  <%= stylesheet_link_tag :all %>
  <%= javascript_include_tag :defaults, '/js/script1.js' %>
  <%= csrf_meta_tag %>
</head>
<body>

<%= yield %>

</body>
</html>

You can include your ERB generated JavaScript files any other layout, too.

Try out the ruby generated JavaScript code!

We need a HTML page to try out our dynamic JavaScript code in action.
We have to generate a HTML test page, what we can request.
Generate this page with this command:

rails generate controller home index

This command produce the following output:

      create  app/controllers/home_controller.rb
       route  get "home/index"
      invoke  erb
      create    app/views/home
      create    app/views/home/index.html.erb
      invoke  test_unit
      create    test/functional/home_controller_test.rb
      invoke  helper
      create    app/helpers/home_helper.rb
      invoke    test_unit
      create      test/unit/helpers/home_helper_test.rb

As you see the home_controller.rb and index.html.erb files created.

Now you can try out the code in action.
Start rails server with rails server command and visit this URL: http://localhost:3000/home/index
And you can also check the generated JavaScript source code here: http://localhost:3000/js/script1.js.
