Laravel Models

In this segment we will focus on creating the model needed for the application. If you remember in the last post on migrations, we created one migration to represent the charities. Now we will utilize Laravel’s powerful Eloquent ORM, which will allow us to represent our database using PHP objects.
Creating Laravel models is actually very simple when done via Artisan. Head to the project root in the command line and enter the following command

php artisan make:model Charity

afterwards open the newly created file app/Charity.php and add the following contents


<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Charity extends Model
{
//
protected $table = 'charities';
protected $fillable = [
'user_id',
'name',
'description',
'monthly_amount'
];
}

The $table variable let’s Eloquent know which table to associate the model with; It is usually not needed, however I prefer to put it in. Next is a $fillable array that holds every attribute needed on a POST request to create a new record. If you look, you will see that there are 2 more Laravel models in the app/ directory. Check them out and read them over and get a good understanding of what’s going on.
app/User.php


<?php
namespace App;
use Laravel\Cashier\Billable;
use Laravel\Spark\Teams\CanJoinTeams;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Foundation\Auth\User as BaseUser;
use Laravel\Spark\Auth\TwoFactor\Authenticatable as TwoFactorAuthenticatable;
use Laravel\Spark\Contracts\Auth\TwoFactor\Authenticatable as TwoFactorAuthenticatableContract;
class User extends BaseUser implements TwoFactorAuthenticatableContract
{
use Billable, TwoFactorAuthenticatable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'email',
'name',
'password',
];
/**
* The accessors to append to the model's array form.
*
* @var array
*/
protected $appends = [
'using_two_factor_auth'
];
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = [
'card_brand',
'card_last_four',
'extra_billing_info',
'password',
'remember_token',
'stripe_id',
'stripe_subscription',
'two_factor_options',
];
}

app/Team.php


<?php
namespace App;
use Laravel\Spark\Teams\Team as SparkTeam;
class Team extends SparkTeam
{
//
}

Laravel Migrations

In this segment we are going to focus on prepping our database. Migrations are a way for you as a developer to manage the schemas for your application’s database tables. This is also where you define the skeleton of your Eloquent models, since their attributes are based off the table they correspond to. For a more in depth understanding of migrations and how they work, go through my Learning Laravel posts.

Command Line Time

Head to the command line and go to the root of the project we created in the last post. Using the artisan CLI tool, we will generate some migrations. Enter the following command

php artisan make:migration create_charities_table --create=charities

This will create a new migration file in the database/migrations folder. Open it up and copy the following code

<?php use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreateCharitiesTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('charities', function (Blueprint $table) { $table->increments('id'); $table->integer('user_id')->unsigned(); $table->foreign('user_id')->references('id')->on('users'); $table->string('name'); $table->string('description'); $table->decimal('monthly_amount',5,2); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::drop('charities'); } }

The first thing we add is a foreign key constraint, so that we can easily identify which charities belong to which user, this will become more apparent in the models post. The next three should be self explanatory; We are collecting the name, description and monthly donation amount for the charity. The monthly_amount will also serve as the amount that is charged for one-time donations. If you noticed there are multiple migrations in the database/migrations folder. We can leave these alone for now, but it would be well worth the time to go through and really understand what those files are doing. In any case when you are ready head back to your command line and issue the following command:

php artisan migrate

Your database is now migrated. If you received any error, make sure your database details are correct in your .env file located at the root of your project directory. Next we will build our Eloquent models. Stay tuned, and remember if you like what you read SHARE IT, and follow me on Twitter @mastashake08
