krzysztofrewak/laravel-conditional-seeders

About

Relatively often I needed to put some logic into seeders and run them accordingly to some conditions (eg. I didn't want to duplicate or overwrite some data, I just wanted to run it once, I just wanted to run it only on certain environment, etc.). Putting these conditions into run() method was making these seeders less readable and putting them into DatabaseSeeder could be dangerous enough (because someone could just ran it from the console).

I added a method authorize() to an abstract Seeder. Method is returning true by default, so it should be completely backward compatible with existing seeders. Conditionally disabling any seeder from running is extremely easy:

class DisabledTestSeeder extends Seeder
{
    public function run(): void
    {
        // (...)
    }

    protected function authorize(): bool
    {
        return false;
    }
}

Of course, it can look like this (to ensure that it will fire only when users table would be empty):

protected function authorize(): bool
{
    return User::count() === 0;
}

Installation

Include this package with Composer:

composer require krzysztofrewak/laravel-conditional-seeders ^1.0

Now you can switch base class of your seeders in database/seeders directory to \KrzysztofRewak\ConditionalSeeder\ConditionalSeeder. By overwriting authorize() method you can conditionally switch on/off seeder in question.

Please remember to change base class of DatabaseSeeder to \KrzysztofRewak\ConditionalSeeder\ConditionalSeeder too. Without it, it won't work properly.
