Hi I am new to creating factories on Laravel and I am setting up a blog website. I had this going just fine and now it isn't working anymore.

When I use "tinker" to add fake data using (App/Models/Post::factory(30)->create();), below error keep occurs. Could anyone please educate me why this error occurs?

App/Models/Post::factory(30)->create(); 
PHP Warning: Use of undefined constant App - assumed 'App' (this will throw an Error in a future version of PHP) in F:\coding\laravel\test-laraveleval()'d code on line 1 
PHP Warning: Use of undefined constant Models - assumed 'Models' (this will throw an Error in a future version of PHP) in F:\coding\laravel\test-laraveleval()'d code on line 1

  • In `php artisan tinker`, try either `Post::factory(30)->create()`, or `\App\Models\Post::factory(30)->create()`. If neither of those works, make sure you have a `Post.php` file within `app/Models`, with the namespace `namespace App\Models;`. Also, in the future, please include code for the Model in your question; it'll help us debug this faster. – Tim Lewis Mar 16 '22 at 17:40

    You're using forward slash ( / ) when you should be using back slash ( \ ). `App\Models\Post::factory(30)->create()` – IGP Mar 16 '22 at 19:27
  • This is really helpful. Thanks. Next time I'll add the relevant codes also. – Malith2007 Mar 17 '22 at 04:55

You have to define factory rules such that you have a constraint in your database that checks for category name uniqueness.

You should read how to write a custom factory in Laravel 8:Examples how to generate factories. enter image description here
