This is a reoccuring requirement: you need a profile for some object in your project.
FE you have a company, a member or a location that should get an address, a marker on the map, an icon, homepage etc.

So I created a small silverstripe module that adds a profile tab to any object you choose in your Silverstripe CMS backend.

It basically extends the very handy addressable module and inherits all functionality from it like automatic geocoding, regex field to validate postcodes, set allowed countries and rendering of a static google map.
If you just need an Address I recommend to use the addressable module.

Install it easy by:
Simply extend your Object in your _config.php:

Object::add_extension('myObject', 'Profileable');

To add the automatic geocoding add:

Object::add_extension('myObject', 'Geocodable');

and of course run: dev/build?flush=all

It also renders the profile in semantic hContact mircroformat markup, just place $getFullProfileHTML in your template and style it.
If you want to render the Profile different just copy the Profile.ss over to your theme and start editing.

In the last days, i was trying to find a solution hosting multiple Express apps on my vServer the same Server.

Starting with Apache and mod_proxy, i ended up with a plain node solution, which i really like.

Let’s take a quick look on some different approaches out there:

—1—

Using apache on port 80 as a proxy

ProxyPass /nodeurls/ http://localhost:9000/
ProxyPassReverse /nodeurls/ http://localhost:9000/

via stackoverflow

– no websockets
++ probably the easiest way to integrate with your running AMPP-stack

—2—

Using a node.js app on port 80 as a Wrapper for other node apps.

express.createServer()
  .use(express.vhost('hostname1.com', require('/path/to/hostname1').app)
  .use(express.vhost('hostname2.com', require('/path/to/hostname2').app)
.listen(80)

via stackoverflow

++ you can use websockets on port 80
– apps crash/restart/stop globally
–what about your apache or the like?

—3—

Using node.js with node-http-proxy on port 80

var http = require('http')
, httpProxy = require('http-proxy');

httpProxy.createServer({
  hostnameOnly: true,
  router: {
    //web-development.cc
    'www.my-domain.com': '127.0.0.1:3001',
    'www.my-other-domain.de' : '127.0.0.1:3002'
  }
}).listen(80);

++ proxy websockets to any port
– you might need to move your old web server to another port

The really cool thing about using node-http-proxy is its capability of proxying websockets.
So you can have your apps running independtly on different ports while serving everything to the user over port 80 and use stuff like socket.io.

Since i’m new to node.js and miles away from beeing a admin, any feedback is highly appreciated :)

to be honest i didn’t find a clean way yet, but i thought this workaround might be worth sharing.

…since Silverstripes‘ Userforms Module Uses jQuery for Validation you can put these lines of code in your UserDefinedForm.ss Template:

jQuery(document).ready(function(){
    jQuery('form label').each(function(){
      jQuery(this).parent().find('input, textarea').attr('placeholder', jQuery(this).html());
      jQuery(this).remove();
    })
  });

This will iterate over the labels in the form , build placeholder attributes from each one and then remove it.

If anyone knows a way how to do this in PHP, i’d appreciate a comment :)

I might be a bit late (yeaikno it exist over a year now and a bunch of blogs had it covered) but nevertheless i would like to point out a very helpful online tool i recently ran into:

jsPerf

Its basically a online benchmark tool for testing different approaches in javascript.
It covers some important aspects of benchmarking, that your homemade bench probably wont have like milliseconds accuracy & statistical analysis.
The tests are run on your browser and the results will feed the “browserscope”. A graph of the “highest known results” for the participating browsers.
So we can see some kind of comparison.

Almost all classic concurrent approaches are covered, my favorites are:

String concatenation

JavaScript Template Engines, in this revision its: juicer, mustache, ejohn, kissy, nTenjin
( yes it has revisions :) )

switchClass OR removeClass and addClass

fastest jQuery selectors to remove class

See if you can find some, you struggled with lately:
http://jsperf.com/browse

JsPerf has some further interesting options like
autorun
append #run to the URL of the test case

filters for the browserscope
filters are: popular, all, desktop, family, major, minor, mobile, prerelease

chart types of browserscope
append #chart=table to the test case’s URL
types are: bar(default), table, column, line, and pie

Give it a try, daily!

I recently started digging into node.js and the express framework.
One thing i like about it is that it comes with the beautiful jade template engine by default.

Here are some things that come real hany when you are working with jade.

This one really saved my mental health in more than one case.
Just paste your HTML and you get nice and clean jade code:

http://html2jade.aaron-powell.com/

If you are using Netbeans, make sure you don’t miss to install the beautifully working plugin for .jade files.

If you are developing in PHP and want to check out jade anyway, check this out:

No seriously, check THIS:

This small composer.json file is used in a project i am working on atm, feel free to use it at own risk. I will provide non-periodical updates and hopefully soon a full upgrade to symfony 2.1.x including doctrine orm 2.2.x.

I still did not get the point regarding dependency resolution, so i simply “composed” the composer file by writing down my own requirements (“i want only the hottest, newest stuff!!”, then tracked down the error messages, removing them by explicetly writing down the missing dependencies by using the latest “dev-*” versions. After that i tried to run the project, which actually did not work, but selective downgrade of some of the bundles (framework, security-extra blahblah) finally did the job.

Feel free to use it in your own projects:

{
	"require" : {
              "symfony/symfony" : "v2.0.12",
              "doctrine/common" : "2.1.4",
              "doctrine/orm" : "2.1.6",
              "symfony/finder" : "v2.0.12",

              "symfony/assetic-bundle" : "2.0-dev",
              "twig/extensions" : "dev-master",
              "jms/security-extra-bundle" : "1.1.0",
              "sensio/framework-extra-bundle" : "2.0-dev",
              "sensio/distribution-bundle" : "2.0-dev",
              "sensio/generator-bundle" : "2.0-dev"

 	},
        "autoload" : {
            "psr-0" : {
                "Acme" : "src/",
            }
        }
}

Create a file named “composer.json” in your project’s root directory, then paste the above code into it and save it.

Now run

$ curl -s http://getcomposer.org/installer | php

After that, download all dependencies by typing

$ php composer.phar install

The easiest way to create a full project including AcmeDemoBundle, AppKernel and the whole stuff is to download the symfony 2 standard distribution without vendors and calling the script from there. The only thing to do is to modify the path to autoload.php, which should point to vendor/.composer/autoload.php.

Now you are able to upgrade your project’s dependencies to the newest versions by simply modifying the composer.json file. Have fun!.

…for some reason i needed to get t h i s to work before going to sleep.

I’m running OSX 10.7.3 with macports which usually does the job, but  Google’s V8 Javascript Engine is not available as a port yet.

So… homebrew to the rescue:

installed it:

/usr/bin/ruby -e "$(/usr/bin/curl -fsSL https://raw.github.com/gist/323731)"

and installed v8

brew install v8

wait, this seems too easy.

PECL installed some beta version of the PHP extension.

sudo pecl install channel://pecl.php.net/v8js-0.1.2

added

extension=v8js.so

to the php.ini file.

und bitteschön:

$v8 = new V8Js();
var_dump($v8->executeString("

//hey i'm Javascript Code

//INSIDE PHP !

//wow.
var hello = 'Hallo';

function helloWorld( string ){
return hello + ' ' + string;
}

helloWorld('World');

"));

Such things might come in handy one day, you know.

When you duplicate a page in the Silverstripe Sitetree, related “has_one” Items are automatically copied, which is nice.

But if you have, lets say, multiple related images on that Page, those are not copied when you duplicate that Page.

After reading this discussion, i found out that it’s actually pretty easy to “fix” this.

This what i ended up with and seems to be working fine:

//assuming your page has the following related Dataobjects

public static $has_many = array(
'Images' => 'MyImageDataObject'
);

public static $many_many = array(
'Something' => 'AnotherPageTypeOrWhatever

);

The following code would automatically duplicate the has_many related DataObjects
and just set the relation to the many_many Objects on the created page:

        

          

              
<?php 

public function duplicate() {
 
  $items_to_duplicate = array(
    'Images',
    'Somehting'
  );
 
  $page = parent::duplicate();
 
  //duplicate has many items
  foreach ($this->has_many() as $key => $className) {
    if (in_array($key, $items_to_duplicate)) {
      foreach ($this->{$key}() as $item) {
        $newField = $item->duplicate();
        $id = get_class($this) . 'ID';
        $newField->{$id} = $page->ID;
        $newField->write();
      }
    }
  }
 
  //set the relation to many_many items on created page
  foreach ($this->many_many() as $key => $className) {
    if (in_array($key, $items_to_duplicate)) {
     $page->{$key}()->addMany($this->{$key}()->getIdList());
    }
  }
 
  return $page;
}

..as already suggested in the forum, i still think this would make a handy core feature, wouldn’t it?
Would be cool to globally specify relations to duplicate in the page-config with something like

public static $relations_to_copy = array(
 'Images',
 'Somehting'
);

Ever wondered how to use the modulo operator in twig, the template engine of symfony?

Actually its like in PHP:

{{ 11 % 7 }}

As described here

But i guess for most use cases modulus is used to check if a number is divisible by another number.
Therefore Twig has the very conveniant divisibleby test function.

{% if loop.index is divisibleby(3) %}

Another modulo use case is to check odd and even rows in loops. There Twig has the built-in function cycle to help you.

{{ cycle(['odd', 'even'], i) }}

Once you know its so eeasy;)

We thought we had to improve our SilverStripe setup script for our development environment.
So Max and me rewrote it to add submodules and some other improvements.

Just run:

./install_silverstripe.sh mynewproject tags/2.4.7

and you have

• silverstripe project folder structure
• the tutorial theme
• a already filled git repository
• sapphire as submodule
• cms as submodule
• Uploadify as submodule
• DataObjectManager as submodule
• UserForms as submodule

What you then still need to do is:

• create the database
• setup a local vhost
• open your project url and run the install process
• start to code

So here it is:

# install silverstripe + common modules from github
# usage sh install_silverstripe.sh <folder_name> <tag/branch>
# examples: 
# sh install_silverstripe.sh some_folder tags/2.4.5
# sh install_silverstripe.sh some_folder master

#set up project base folder
git clone git@github.com:silverstripe/silverstripe-installer.git $1
cd $1
git checkout $2
#we kill the .git because we want this repo just as starter and init our own repository (instead of export)
rm -rf .git

#set permissions for install
chmod 0777 assets assets/*
chmod 0666 .htaccess mysite/_config.php assets/*/*

git init

git submodule add git@github.com:silverstripe/silverstripe-cms.git cms
cd cms
git checkout $2
cd ..
git add cms
git commit -m "checked out submodule cms to $2"

git submodule add git@github.com:silverstripe/sapphire.git sapphire
cd sapphire
git checkout $2
cd ..
git add sapphire
git commit -m "checked out submodule sapphire to $2"

# add common modules
git submodule add git://github.com/unclecheese/Uploadify.git uploadify
git submodule add git://github.com/unclecheese/DataObjectManager.git dataobject_manager
git submodule add git://github.com/silverstripe/silverstripe-userforms.git userform

git submodule init
git submodule update

git add .
git commit -m "Initial Commit"
