I'm work on Restful API , I have exception message when i want to make seeding fake data in database.
I make database fresh .

I make model with migration and controller:
Migration: 000000_create_posts_table.php
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('title');
$table->text('content');
$table->dateTime('date_written');
$table->String('feature_image')->unllable();
$table->integer('votes_up')->unllable();
$table->integer('votes_down')->unllable();
// TelationShipe.
$table->integer('user_id');
$table->integer('category_id');
$table->timestamps();
});
Model: Post.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
protected $fillable = [
'title' , 'content' , 'date_written' ,
'feature_image' , 'votes_up' ,
'votes_down' , 'user_id' ,
'category_id'
];
}
Controller: PostController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class PostController extends Controller
{
//
}
Seeder: DatabaseSeeder.php
<?php
use Illuminate\Database\Seeder;
class DatabaseSeeder extends Seeder
{
/**
* Seed the application's database.
*
* #return void
*/
public function run()
{
factory(\App\Post::class , 100 )->create();
}
}
Factory: PostFactory.php
<?php
/** #var \Illuminate\Database\Eloquent\Factory $factory */
use App\User;
use Faker\Generator as Faker;
use Illuminate\Support\Str;
/*

*/
$factory->define(User::class, function (Faker $faker) {
return [
'title' => $faker->title,
'content' => $faker->text(400),
'date_written' => $faker->new(),
'feature_image' => $faker->imageUrl(),
'votes_up' => $faker->numberBetween(1 , 100),
'votes_down' => $faker->numberBetween(1 , 100),
'user_id' => $faker->numberBetween(1 , 15),
'category_id' => $faker->numberBetween(1 , 15),
];
});
but the actual output console :

243| }
244|

Exception trace:

Answer 1

Change this line
From
'date_written' => $faker->new(),
To
'date_written' => now(),
now() will return a Carbon instance of the current time which your database migration require
There's no such function on faker generator called new
Hope this helps
