Dream your application like youtube? First of all, this application is only working in UNIX Machine, and has not been tested to Windows. This article is taken from written of johndahl.

First, install the gem:

sudo gem install rvideo
.

sudo port install ffmpeg
.

sudo port install ffmpeg +lame +libogg +vorbis +faac +faad +xvid +x264 +a52
.

sudo gem install flvtool2
.

file = RVideo::Inspector.new(:file => "#{FILE_PATH}/filename.mp4")
file.video_codec # => mpeg4
file.audio_codec # => aac
file.resolution # => 320x240

command = "ffmpeg -i $input_file -vcodec xvid -s $resolution$ $output_file$"
options = {
:input_file => "#{FILE_PATH}/filename.mp4",
:output_file => "#{FILE_PATH}/processed_file.mp4",
:resolution => "640x480"
}

transcoder = RVideo::Transcoder.new

transcoder.execute(command, options)

transcoder.processed.video_codec # => xvid

• First Create file by uploading the video to your "#{APP_ROOT}/files/file_name.video_ext", you can use act_as_attachment to do it. Example your file is input.mp4.

• Then in your controller you can run file inspector object like script below:

file = RVideo::Inspector.new(:file => "#{APP_ROOT}/files/input.mp4")

file = RVideo::Inspector.new(:raw_response => @existing_response)

file = RVideo::Inspector.new(:file => "#{APP_ROOT}/files/input.mp4", :ffmpeg_binary => "#{APP_ROOT}/bin/ffmpeg")

file.fps # => "29.97"
file.duration # => "00:05:23.4"

• To transcode video, you should initialize a trancoder object :

transcoder = RVideo::Transcoder.new
.

• Then pass a command and valid options to the execute method.

recipe = "ffmpeg -i $input_file$ -ar 22050 -ab 64 -f flv -r 29.97 -s"
recipe += " $resolution$ -y $output_file$"
recipe += "\nflvtool2 -U $output_file$"
begin
transcoder.execute(recipe, {:input_file => "/path/to/input.mp4",
:output_file => "/path/to/output.flv", :resolution => "640x360"})
rescue TranscoderError => e
puts "Unable to transcode file: #{e.class} - #{e.message}"
end

• If the job succeeds, you can access the metadata of the input and output files with:

transcoder.original # RVideo::Inspector object
transcoder.processed # RVideo::Inspector object

• Or you can use another Template for you View:
  

<% if video.processing_status == 2 %>
<div id="videoplayer<%= video.id %>">
<p>This item requires Macromedia Flash Player 7.</p>
<p>To get the latest version please <a href="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" target="_blank">click here</a>.</p>
</div>
<script type="text/javascript">
var so = new SWFObject("/flash/vidplayer.swf?filePath=<%= url_for_file_column(video, 'file') %>.flv&thumbPath=<%= url_for_file_column(video, "file")%>.jpg", "vidplayer", "336", "326", "7", "");
so.addParam("menu", "false");
so.write("videoplayer<%= video.id %>");
</script>
<strong><%= video.title.titleize %></strong><br />
<%= video.body %><br/>
<%= link_to image_tag("icon_video.gif"), url_for_file_column(video, "file") %>
<%= link_to "download original", url_for_file_column(video, "file") %>
<% else %>
<strong><%= video.title.titleize %></strong><br />
<%= video.body %><br/>
<%= link_to image_tag("icon_video.gif"), url_for_file_column(video, "file") %>
<%= link_to "download original", url_for_file_column(video, "file") %>
<p>This video is still being converted, or else there has been some kind of error.</p>
<% end %>

• Make it simple and never think as frustration then you will success.

--------------------------
Summary
--------------------------
clickatell gem is served to you for sending sms from your ruby application or shell console. This way is only work in linux, BSD and OSX. To use this gem, you will need sign up for an account at the Clickatell website. Once you are registered and logged into your account centre, you should add an HTTP API connection to your account. This will give you your API_ID.


--------------------------
Proof of Concept
--------------------------

• install gem : {$} gem install clickatell

• import or checkout the clickatell trunk repositroy

svn co svn://lukeredpath.co.uk/var/svn/opensource/clickatell/trunk clickatell-trunk

OR

git clone git://github.com/lukeredpath/clickatell.git

• You can now use the library directly. You will need your API_ID as well as your account username and password.

require 'rubygems'
require 'clickatell'

api = Clickatell::API.authenticate('your_api_id', 'your_username', 'your_password')
api.send_message('6285212345678', 'Hello from clickatell & teapoci')

• Full documentation for the API is available in the RDocs. For debugging purposes, the API allows you to view gateway URIs as they are requested, printed to $stdout. You can enable this by turning on debug_mode.
  

Clickatell::API.debug_mode = true
.

• The Clickatell gem also comes with a command-line utility that will allow you to send an SMS directly from the command-line.

• You will need to create a YAML configuration file in your home directory, in a file called .clickatell that resembles the following:
  

# ~/.clickatell
api_key: your_api_id
username: your_username
password: your_password

• You can then use the sms utility to send a message to a single recipient:

{$} sms 6285212345678 'Hello from clickatell & teapoci'
.

• You can also specify a custom Sender ID – the name or number that will appear in the “From” label on the recipients phone. You can either add a “from” key to your .clickatell file or manually using the—from option:

{$} sms --from 'Luke Redpath' 447771234567 'Hello from clickatell'

Before

• Install plugin : ruby script/plugin install http://svn.rubyonrails.org/rails/plugins/auto_complete/

• Modify your product.rb

class Product < ActiveRecord
belongs_to :category

def category_name
category.name if category
end

def category_name=(name)
self.category = Category.find_or_create_by_name(name) unless name.blank?
end

end

• Create or Modify your categories_controller.rb at def index

def index

@categories = Category.find(:all, :conditions => ['name LIKE ?', "%#{params[:search]}%"])

end

• Create a new file & add script below in views/categories/index.js.erb or index.rjs.
  

<%= auto_complete_result @categories, :name %>

• Open your view which is containing form field for your production controller. Then add text_field_with_auto_complete to your wanted text_field, example :

<%= f.label :category_name %>
<%= text_field_with_auto_complete :product, :category_name, { :size => 15 }, {:url => formatted_categories_path(:js), :method => :get, :with =>" 'search=' + element.value" } %>

#if you get error for formatted_categories_path
#go to your route.rb then add : map.resources :categories

#if get error on text_field_with_auto_complete
#go to your route.rb then add :
#map.resources :products, :collection => {:auto_complete_for_product_category_name => :get }

• Don't forget to put script below into your layout example application.html.erb/rhtml or production.html.erb/rhtml

<%= javascript_include_tag :defaults %>

This way is very simple and fast to make us states list for your view or drop down menu.

• ruby script/plugin install http://svn.techno-weenie.net/projects/plugins/us_states/
  
• <%=us_state_select :post, :state %>

There's many sites that provide you country list in sql file, so you can import it to your database. I would like to introduce you ruby way to create country list for your drop down menu. Let's we start :

• gem install tzinfo

• ruby script/plugin install tzinfo_timezone

• Add the code below to your Application_helper.rb
  

def make_attributes(hsh)

unless hsh.nil?
output = ""

hsh.each
do key, val
output << "
#{key}=\"#{val}\""
end
end
output
end



def country_code_select(object, method, priority_countries=nil, options={},
html_options={})


countries =
[TZInfo::Country.all.collect{xx.name},
TZInfo::Country.all_codes].transpose.sort

if
priority_countries.nil?
output = select(object, method, countries, options,
html_options)

else
output = "< id="'#{object}_#{method}'"
name="'#{object}[#{method}]'#{make_attributes">\n"


if
options[:include_blank] == true
output <<
""
end


priority_countries.each do pc
if options[:selected] ==
pc[:code] or options[:selected] == pc[:name]
output <<
"#{pc[:name]}\n"
else
output <<
"#{pc[:name]}\n"
end
end

output <<
"----------------------------\n"

output <<
options_for_select(countries, options[:selected])

output <<
"< / select >\n"
end
output

end

• Add this code to your view :

Good Luck

.

There's many render types that we can use for our view. Rails Render is a strong method that helps you to render your web pages. It comes with many flavors including:

• Render Action : render an action in the current controller, you can specify if you want layout printed or not.

render :action => "show_home_page", :layout=> false

.

• Render partial: it renders part of your web page.

render :partial => "left_menu"

.

• Render template: render a page, the file path is relative to your application.

render :template=> "templates"

.

• Render file: absolute path is needed

render :file => "#{RAILS_ROOT}/public/file.html"

.

• Render text

render :text => "You can put any text here"

.

• Render Json

render :json => {:name => "Teapoci"}.to_json

.

1 . Nice Edit

• Create your text area in your form_tag range

<%= text_field "demo", "tea_poci", "id"=>"myArea2", :rows=>10, :cols=>22%>

.

• Create additional button for option of using text editor or not.

<%= submit_tag "Add Editor",:type => 'button', "onclick"=>"addArea2();" %>

<%= submit_tag "Remove Editor",:type => 'button',
"onclick"=>"removeArea2();" %>

• Put this code under submit_tag "Remove Editor" :

<script type="text/javascript" src="http://js.nicedit.com/nicEdit-latest.js">


</script>

<script type="text/javascript">


//<![CDATA[

var area1, area2;

function addArea2() { area2 = new nicEditor({fullPanel : true}).panelInstance('myArea2');}

function removeArea2() { area2.removeInstance('myArea2'); }


bkLib.onDomLoaded(function() { toggleArea1(); });


//]]>


</script>

• Done !! You can see image below :

• [~] gem install RedCloth

• [~] ruby script/plugin install svn://errtheblog.com/svn/plugins/acts_as_textiled

• [~] script/plugin install http://svn.webtest.wvu.edu/repos/rails/plugins/textile_editor_helper/

• [~] rake textile_editor_helper:installGo to yor Model / Active Record that is corresponding to your text_area and put :

class MyModel < ActiveRecord
acts_as_textiled :my_text

end

• Enable your prototype.js.

<%= javascript_include_tag 'prototype' %>
.

• Here's a short code for your rhtml or html.erb :

<%= textile_editor 'item', 'my_text' -%>
<%= textile_editor_initialize -%>

• Demo Editor here

• Download widgEditor

• Extract the files

• Copy the widgEditor.js file into your applications public/javascripts folder (you can configure it by changing this file)

• Copy the widgEditor.css file into your applications public/stylesheets folder.

• Copy all the images from the widgEditor distribution to your public/images folder.

• Include the javascript and css files in your layout file.

• Give any text field you want to be an editor field a class of “widgEditor”.

• Here's a short code for your view :

<'HEAD'>
<'/HEAD'>
<% form_tag :action => 'what ever' do %>
< %= stylesheet_link_tag 'widgEditor' %>
< %= javascript_include_tag 'widgEditor' %>
< %= text_area 'node', 'content', :cols => "50", :rows=>"3", :class=>"widgEditor" %>
<% end %>
<% end_form_tag %>

There's many ways to create photo gallery, i want share my experience with very instant photo gallery. Begginer or advance can do it, it's easy. I am using windows OS, Ruby ruby 1.8.5. Let's Start your ruby

• Step 1 : Download Rmagick(2.3.0) & imageMagick(6.4.0) in 1 Package Here (Download Package).

if you use linux, install imageMagick Library (sudo apt-get install libmagick9-dev) and then install rmagick (sudo gem install rmagick), after that skip step 2.

• Step 2 : extract package to /ruby/your_app/tmp, make sure that rmagick-2.x.x.tar.gz and rmagick-2.x.x-x86-mswin32.gem are in that tmp folder. After that run it:

gem install rmagick --local
.

• Step 3 : Install attachment_fu plugin
  

ruby script/plugin install http://svn.techno-weenie.net/projects/plugins/attachment_fu/

• Step 4 : Generating the Scaffolding Code

ruby script/generate scaffold_resource Gallery
.

• Step 5 : Create Gallery Table for DataBase or Gallery Migration, open your db/migrate/001_create_galleries.rb, then insert it :

class CreateGalleries < Migration
t.column :filename, :string, :limit => 255
t.column :path, :string, :limit => 255
t.column :parent_id, :integer
t.column :thumbnail, :string, :limit => 255
t.column :size, :integer
t.column :width, :integer
t.column :height, :integer
end
end

def self.down
drop_table :galleries
end
end

• Step 6 : After that run this command : rake db:migrate

• Step 7 : Set up your picture size, open app/models/gallery.rb
  

class Gallery < ActiveRecord

has_attachment :storage => :file_system,
:resize_to => '>550x>413',
:thumbnails => { :thumb => '>100x>75'},
:size => 0.megabyte..3.megabytes,
:content_type => :image,
:processor => 'Rmagick'
validates_as_attachment

end

• Step 8 :Edit your controller gallery_controller.rb
  

def index

@gallery_pages = Paginator.new(self, Gallery.find(:all).count, 5, params[:page])
@photos = Gallery.find(:all, :order => 'created_at DESC', :limit => @gallery_pages.items_per_page, :offset => @gallery_pages.current.offset)

respond_to do |format|
format.html # index.rhtml
format.xml { render :xml => @gallery.to_xml }
end
end


def create

@gallery = Gallery.new(params[:gallery])
@galleries = Gallery.find(:all)

respond_to do |format|

if @galleries << @gallery flash[:notice] = 'Gallery was successfully created.' format.html { redirect_to(@gallery) } format.xml { render :xml => @gallery, :status => :created, :location => @gallery }
else
format.html { render :action => "new" }
format.xml { render :xml => @gallery.errors, :status => :unprocessable_entity }
end
end
end

• Step 9 :Edit your uploading form to your new.rhtml

• Step 10 : Activate your server and run your application.

I really dont understand what happen in my government brain nowdays, Indonesia is not Religion Country, but why because of a movie, many important site are blocked by government request, examples are Youtube.com, Rapidshare.com and many things. Even I read on Okezone.com and Detik.com, the government will block all blog sites. It's damn jerk. My government never think that if they block many digital audio visual services online, they will freeze many e-learning sites that use youtube.com for their support media. And it freezes creativities of netters that already have been appreciating their idea to blog sites.

You know what my works are reduced to 40%, because youtube is really helping me by their tutorial online, and watch my favourite USA broadcast. I was hopeless in minutes, but my brain gave me idea. These are other ways to access blocked sites.

1. USING PUTTY for TELNET
It will change your IP address to Singapore Address, I got this tutorial from palzum.blogsome.com. You can follow steps below:

• Download putty for windows & linux here (save it to c:\windows for WIN_OS)
• Modify your browser Network/Connection Setting trough this way :

[ For Mozzila/Flock/FireFox]
-------------------------------

click Tools --> Options --> Advanced --> NetWork Settings, then do setting like screenshot below :


[FOR INTERNET EXPLORER]
--------------------------------
1. click Tools - Internet Options - Connections - Lan Settings
2. Marked 'Proxy Server' and click 'Advance' button
3. Set it like the following screenshot

• [windows] Click Start Menu => Run and enter putty -P 222 -N -D 9999 -C net@cepat.abangadek.com
  
• [linux] open your terminal then type it. ssh -o "CompressionLevel=9" -C -D 9999 -p 22 -N net@cepat.abangadek.com
  
• Enter password : cepat123, then minimize your putty (never close your putty!!)
  
• Open your browser and see there that now you can access back the blocked sites.

• open google and type browse anonymously free, you will get many online services that offer browsing anonymouse. Example we take http://surfatworkfree.info/
• and enter the blocked site address to a provided box or field of url then press 'browse' button.

[1] you can import svn http://svn.nanorails.com/plugins/action_mailer_tls/ to your /vendor/plugins/

[2] edit your environment.rb by adding the last line this code:

require "smtp_tls"

ActionMailer::Base.raise_delivery_errors = false
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.server_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'gmail.com',
:user_name => "convert.ruby.to@gmail.com",
:password => "rubyisred",
:authentication => :plain
}

def paginate_collection(collection, options = {})

default_options = {:per_page => 10, :page => 1}
options = default_options.merge options

pages = Paginator.new self, collection.size, options[:per_page], options[:page]
first = pages.current.offset
last = [first + options[:per_page], collection.size].min
slice = collection[first...last]
return [pages, slice]
end

@pages, @users = paginate_collection User.find_custom_query, :page => @params[:page]
