Backend CodeIgniter Models

When to use this skill

• Database operations
• Using entities
• Query builder
• Data validation

Workflow

• Extend CodeIgniter\Model
• Define table and fields
• Use entities for type safety
• Enable validation
• Use callbacks

Instructions

Model with Entity

<?php

namespace App\Models;

use CodeIgniter\Model;

class UserModel extends Model
{
    protected $table = 'users';
    protected $primaryKey = 'id';
    protected $returnType = 'App\Entities\User';
    protected $allowedFields = ['name', 'email', 'password'];
    protected $useTimestamps = true;
    protected $validationRules = [
        'email' => 'required|valid_email|is_unique[users.email]',
        'password' => 'required|min_length[8]'
    ];

    protected $beforeInsert = ['hashPassword'];

    protected function hashPassword(array $data)
    {
        if (isset($data['data']['password'])) {
            $data['data']['password'] = password_hash($data['data']['password'], PASSWORD_DEFAULT);
        }
        return $data;
    }
}

Entity

<?php

namespace App\Entities;

use CodeIgniter\Entity\Entity;

class User extends Entity
{
    protected $casts = [
        'id' => 'integer',
        'is_active' => 'boolean',
        'created_at' => 'datetime'
    ];

    public function setPassword(string $password)
    {
        $this->attributes['password'] = password_hash($password, PASSWORD_DEFAULT);
        return $this;
    }
}
