Use RAW Eloquent Queries with Slim PHP - php

Question

I am working on a project with SlimPHP and Eloquent.
I am trying to run a RAW SQL query within a Model's method, like this:
/models/Form.php
<?php
namespace models;
class Form extends \Illuminate\Database\Eloquent\Model {
protected $table = 'forms';
public function getResponses($form_id)
{
// HERE
$select = \Illuminate\Support\Facades\DB::select('select 1');
return 1;
}
}
I am using Capsule to bootstrap the ORM.
The code above gives me:
Fatal error: Call to a member function select() on a non-object in
/vagrant/vendor/illuminate/support/Illuminate/Support/Facades/Facade.php
on line 208
Documentation is of very help in this case, could you shed some light on this?
thanks

Answer 1

Read the setup instructions on github closely and make sure you follow them correctly.
With Capsule you should use Illuminate\Database\Capsule\Manager or as DB "Facade".
$select = \Illuminate\Database\Capsule\Manager::select('select 1');
I usually import it and define an alias:
use Illuminate\Database\Capsule\Manager as DB;
// ...
$select = DB::select('select 1');

Plus if you need to do raw query, it may help to call setAsGlobal() after bootEloquent() like this
$capsule->addConnection($sqliteDb);
$capsule->bootEloquent();
$capsule->setAsGlobal(); // <--- this

In Slim 4,
we can use $this->getConnection()->select($sql);
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Product extends Model{
protected $table = 'products';
public $timestamps = false;
protected $fillable = ["name", "price", "quantity", "supplier", "image", "category"];
public function getProductsByCategory(){
$sql = 'SELECT p.id,
p.name,
p.price,
p.quantity,
p.supplier,
p.image,
p.category,
(SELECT IF(COUNT(*) >= 1, TRUE, FALSE) FROM favorite f WHERE f.user_id = 1 AND f.product_id = p.id) AS isFavourite,
(SELECT IF(COUNT(*) >= 1, TRUE, FALSE) FROM carts c WHERE c.user_id = 1 AND c.product_id = p.id) AS isInCart
FROM products p';
return $this->getConnection()->select($sql);
}
}
