Symfony Base Admin. New project

At the end of April 2014 I wanted to start testing Symfony taking a base project that was already done in Bonfire/ Codeigniter.

Now the time has come, and I’ve been working with Symfony for about 3 months, so I have more MVC knowledge with the framework. At the same time I was searching for something that was similar as Bonfire to start an easy Admin Panel for some projects. I searched for two weeks but didn’t find anything similar, so no surprise there is no easy panel, you must make your own. And it’s not rocket science, so instead of complaining, let’s do it ;)

With this basic principles in mind:

  • As least components as possible, using Symfony last edition, currently 2.5.* as defined in composer.json
    If we add a new component, is because it’s used somewhere, and it’s commented along with a proper commit in the repository. The goal is that the vendors folder is clean and to to keep the starting codebase to a minimum extent.
  • An easy way to link existing SQL tables to entities, using Doctrine ORM. ( There is no import functionality as in Bonfire )
  • Use the quite well documented Sonata, to make this possible, adding the basic functionality and some examples of how to achieve CRUD functionality.
  • Twitter bootstrap in the admin and if possible also in the front-end, to keep a well designed responsive base design 

Putting this in a Public repository on github so anyone can fork it, modify it and use it for any project.

OOP Fundamentals

There are many different takes on object oriented programming. I’ve saw this video of “Uncle Bob” latest week and I wanted to write a post about the fundamentals of OOP programming.

http://vimeo.com/64086087

I like the way he explains OOP, interfaces, polymorphism and other related areas of object oriented methodology. So before starting with my post series of Symfony, I wanted to review a couple of basics, and how they are supposed to be used.

The benefits of working using OOP is that the application itself becames minimal, and the modules can be coded in independant pieces, that have a decoupled arquitecture and are independantly deployed, hence repairing a certain part does not brake the others. In Symfony this modules are called bundles. A good programming example, is the Symfony components itself, and another Business Logic example I’ve seen recently with independant Bundles is Elcodi.

HISTORY

The formal programming concept of objects was introduced in the 1960s in Simula 67, a major revision of Simula I, a programming language designed for discrete event simulation, created by Ole-Johan Dahl and Kristen Nygaard of the Norwegian Computing Center in Oslo.  Simula introduced the notion of classes and instances or objects (as well as subclasses, virtual methods, coroutines, and discrete event simulation) as part of an explicit programming paradigm.

DEFINITIONS. THE BIG 3

Encapsulation is the packing of data and functions into a single component. The features of encapsulation are supported using classes.

Inheritance is when an object or class is based on another object or class, using the same implementation or specifying implementation to maintain the same behavior (realizing an interface; inheriting behavior). It is a mechanism for code reuse and to allow independent extensions of the original software via public classes and interfaces. The relationships of objects or classes through inheritance give rise to a hierarchy.

Polymorphism is when source code dependancy is opposed to the source of control.

Symfony2 Routing cheat sheet

Symfony2 Forms cheat sheet

Symfony 2. New series of Posts coming !

It’s been quite a while I don’t post anything here.

And there is a good reason: I’m quite busy. My family comes to visit a Berlin, got a new full time job as a developer, and when I come back home I still keep on reading documentation and doing simple code examples, that I do not push anywhere because they are only learning sh!ts so far.

But soon I’m planning to release some stuff and maybe create some new sites with Symfony, that serve a purpose. But no more client work for some time, I just want to arrive home, and do other things as reading books, hearing some music or just hang around with friends. Also it’s about 3 months I’m going to a very cool Salsa class every Tuesday and Sunday. Salsakurs is now Mittlestuffe, not anymore the boring basics :)

One of the most interesting books I read so far, and still re-reading it when I want to apply some stuff is “A Year with Symfony” . A name that honours the labour, since it’s only 3 months I started learning the framework and I still feel that I know only 10% of it.

So I wish you all a good, sunny and entertaining Summer!

 

Neues Projekt: Codeigniter wegen Symfony 2

Ich habe noch 1 Woche Zeit. Die Aufgabe ist, diese kleine MVC Projekt:

https://github.com/martinberlin/onstage

In Codeigniter MVC, nach Symfony 2 MVC framework Weiterentwicklung

Dann Ich freue ich mich sowohl in Bezug auf die Frameworks vergleichen in Hinsicht auf:

  • Geschwindigkeit
  • Struktur und Data Models
  • und wie schwer ist es, eine Admin-Panel zu Entwickeln
    (and how hard is to code an admin panel, in case my german is not so clear)

 

How to add Bonfire to an existing Codeigniter framework project

MISSION: Integrate simple codeigniter project https://github.com/martinberlin/onstage
with bonfire powerfull HMVC modules and administration access.

Step 1

Copy application and bonfire folders into project root.

 

Step 2

Modify existing MY_loader class that will be overridden by Step 1 with your custom functions. In my case, I was using sparks library and the existing codeigniter theme functionality. So I left :

application/core

/* load the MX_Loader class */
require APPPATH.”third_party/MX/Loader.php”;

/* This will be class MY_Loader extends CI_Loader {}  in your Codeigniter project */

class MY_Loader extends MX_Loader {

// And copied here my custom methods.

}

Step 3

Routing and class names:

http:/onstage/public/index.php/event/hamburg/215  (Local test)
Fatal error: Cannot redeclare class Events in C:\xampp\htdocs\onstage\bonfire\libraries\events.php on line 33

Small fail: It seems bonfire already has a class called events. And collides with my own events controller…So I will rename it to something else and change routing accordingly.

So, we update the route:
$route['event/(:any)/(:num)'] = “eventos/lookup/$1/$2″;
And the corresponding file controllers/events.php to eventos.php . This is the beautiful part of MVC. We just changed some files and routing, but the URL call will be exactly the same. This internal changes won’t affect at all any frontend functionality.

Ok and now the latest routing update, this time in the apache virtual host, the codeigniter goes to the root. But the Bonfire default is the public directory.

With this change, so far, almost all old codeigniter project is working like before, with the added plus that now has a Bonfire administration. But we have still some routes to correct.
For example, the old city route is no longer working:

http://onstagekonzerte.de/hamburg/

Drops a 404. But the application/config/routes.php are there :
$route['hamburg'] = “home/hamburg”;
$route['munich']    = “home/munich”;

And the home controller has those methods inside. So I yet have to find those.

UPDATE:

The solution to my path problem was solved in two steps:

a)  First changing the application/config.php and removing the index.php page from the index_page variable:
$config['index_page'] = ”;

b)  Modifying the view paths to css / js external HTML resources, referring to step 2 since bonfire goes to /public as default:

<link rel=”stylesheet” href=”/public/css/alpha_background.css”>  So now new route will be :
<link rel=”stylesheet” href=”css/alpha_background.css”>

After this I had http://onstagekonzerte.de running in the front exactly as before, with the benefit of having a complete bonfire admin in the back-end.

I’ve posted this in the bonfire forum to see if I can get some feedback and also to share with others, since this is a completely open project where all changes will be shared on a github account where anyone can fork, edit, and comment on changes.
