Routing

http://laravel.com/docs/routing

GET

// app/routes.php
Route::get('/', function()
{
    return 'Hello World';
});

POST

Route::post('foo/bar', function()
{    return Input::all();
});

ROUTING

Recibir Parámetros de la URL

Route::get('user/{id}', function($id)
{    return User::find($id)->get();
});

Asociar una ruta a un método

Route::get('user/{id}', 'UserController@showProfile');

ROUTING

Laravel soporta Resourceful Controllers

Route::resource('photos', 'PhotoController');


Route::get('photos', 'PhotoController@index');Route::get('photos/create', 'PhotoController@create');
Route::post('photos', 'PhotoController@store');
Route::get('photos/{id}', 'PhotoController@show');
............

REST

Verb	Path	Action	Route Name
GET	/photos	index	resource.index
GET	/photos/create	create	resource.create
POST	/photos	store	resource.store
GET	/photos/{id}	show	resource.show
GET	/photos/{id}/edit	edit	resource.edit
PUT/PATCH	/photos/{id}	update	resource.update
DELETE	/photos/{id}	destroy

Filtros

Se ejecutan antes y/o despues de cada
request a la ruta que lo apliquemos.

Route::get('/administrator', ['before' => 'admin'], function()
{    // podemos asumir que el usuario esta logueado.
    return 'Admin page!';
});

Route::filter('admin', function()
{
    if (!Auth::check())
    {
        // Redirect al login
    }
});

Eloquent ORM

http://laravel.com/docs/eloquent

$users = User::all(); // Todos los usuarios de la DB
User::create(['nombre' => 'Pablo']); // Crea al usuarioUser::find(1)->delete(); // Borra al usuarioUser::find(1)->nombre; // Pablo

// app/models/User.php

class User extends Eloquent {    // Todo opcional
    protected $table = 'usuarios';    protected $fillable = ['nombre', 'mail'];    protected $guarded = 'id';
    protected $hidden = 'password';
}

Relaciones


  $user = Post::whereSlug('el-post')->user;


  $comments = Post::find(1)->comments;

class Post extends Eloquent {

    public function comments() {
        return $this->hasMany('Comment');
    }

    public function user() {
        return $this->belongsTo('User');
    }
}

Paginación


$someUsers = User::where('votes', '>', 100)->paginate(15);
// En la vista
{{ $someUsers->links() }}

Fluent Query Builder

http://laravel.com/docs/queries

Métodos también disponibles utilizando un modelo de Eloquent.
DB::table('users')-> se reemplaza por User::

// Todos los usuarios$users = DB::table('users')->get();

// El primer usuario cuyo campo 'name' sea John$user = DB::table('users')->where('name', 'John')->first();

// Solo el valor del campo nombre$name = DB::table('users')->where('name', 'John')->pluck('name');

// Varios filtros$users = DB::table('users')
                    ->where('votes', '>', 100)
                    ->orWhere('name', 'John')
                    ->get();

// JoinsDB::table('users')
            ->join('contacts', 'users.id', '=', 'contacts.user_id')
            ->join('orders', 'users.id', '=', 'orders.user_id')
            ->select('users.id', 'contacts.phone', 'orders.price');

Migrations

Control de Versión para nuestra base de datos.

Rollback

php artisan migrate:rollback

php artisan migrate:make --create="users" create_users_table

php artisan migrate:make add_votes_to_user_table --table=users

Jeffrey Way's Generators

https://github.com/JeffreyWay/Laravel-4-Generators

php artisan generate:migration create_posts_table
--fields="title:string, body:text"

php artisan migrate

Blade Template Engine

http://laravel.com/docs/templates

Layout

// Archivo en /app/views/layout.blade.php<html>
    <body>
        HTML general a todo el proyecto, botoneras, etc.
        <div class="container">
            @yield('content') // Contenido variable para cada vista
        </div>
    </body>
</html>

Extender un Layout

@extends('layouts.master')

@section('content')
    <p>This is my body content.</p>
@stop

PHP parser y flow control

@for ($i = 0; $i < 10; $i++)
    The current value is {{ $i }}
@endfor

@foreach ($users as $user)
    <p>This is user {{ $user->id }}</p>
@endforeach

@while (true)
    <p>I'm looping forever.</p>
@endwhile
@if (condition)
    <p>I'm looping forever.</p>@elseif(condition)
    <p>I'm looping forever.</p>@else
    <p>I'm looping forever.</p>
@endif

{{ date() }} es igual a <?php echo date(); ?>
