Laravel Factory – generate fake json array data with random amount of iterations in a single column

In ListingFactory.php I have something like this

return [
    'reviews' => json_encode([
        'user' => fake()->name(),
        'body' => fake()->paragraph(),
    ]),
]

Additionally, in the DatabaseSeeder.php I have this at the moment

AppModelsListing::factory(10)->create();

The current problem is that it will always generate one instance of review. What I want is a random number of reviews in a range.

For example, right now the table column of Review will always be [{}], I want something like [{}, {}, {}] or [].

    Simply generate your fake data in loop.

    $reviews = [];

foreach(range(1,10) as $i) { // f.e. run it 10 times
  $reviews[] = [
     'user' => fake()->name(),
     'body' => fake()->paragraph(),
  ]
}

return [
      "reviews" => json_encode($reviews),
 ]

    I would believe that randomElements() can do what you want, it takes x elements from a sequence. Combine that with a random number and you would achieve that.

    json_encode(fake()->randomElements(
    [
        [
            'user' => fake()->name(),
            'body' => fake()->paragraph(),
        ],
        [
            'user' => fake()->name(),
            'body' => fake()->paragraph(),
        ],
        [
            'user' => fake()->name(),
            'body' => fake()->paragraph(),
        ],
    ],
    random_int(1, 3),
)),

    If you would change the amount of reviews, increase random_int(1, 10) for a sequence of 10.

    Don’t make it complicated. Just generate a random number and then generate that many reviews.

    $reviews = [];
$amount = rand(1,10);

for($x = 0; $x < $amount; $x++ ){
   $reviews[] = [
        'user' => fake()->name(),
        'body' => fake()->paragraph(),
    ];
}


return [
    "reviews" => json_encode($reviews),
];
